Abstract
Cash transfer programs are rapidly becoming a key component of the social safety net of many countries in Sub-Saharan Africa. The primary aim of these programs is to help households improve their food security and smooth consumption during periods of economic duress. However, beneficiary households have also been shown to use these programs to expand their microentrepreneurial activities. Cluster-randomized trials carried out during the rollout of large-scale programs in Malawi and Zambia reveal that children may increase their work in the household enterprise through such programs. Both programs increased forms of work that may be detrimental to children, such as activities that expose children to hazards in Malawi and excessive working hours in Zambia. However, both programs also induced positive changes in other child well-being domains, such as school attendance and material well-being, leading to a mixed and inconclusive picture of the implications of these programs for children.

1. Introduction
Cash transfer programs providing regular unconditional income support to ultrapoor and vulnerable households are rapidly becoming a key component of the social safety net of many countries in Sub-Saharan Africa (World Bank 2018). The primary aim of these programs is to help households improve food security and smooth consumption during periods of economic duress. Beyond this primary aim, cash transfers may increase the investment of credit-constrained beneficiary households in (typically agricultural) microenterprises. For instance, see Handa, Daidone et al. (2018), who summarize impacts of eight cash transfer programs in Sub-Saharan Africa, including the ones in Malawi and Zambia studied here.1
For a combination of reasons, children may increase their work in the expanded household enterprise. Cash transfer programs often target households with a high ratio of dependents to healthy adults. As a result, these households may be constrained in their capacity to augment the labor supply of adult members. Moreover, labor market imperfections may limit the ability of households to hire external labor. Liquidity constraints may raise the shadow price of inputs that require cash payments, such as hired labor, making it more efficient to rely on family labor (Singh, Squire, and Strauss 1986). And the benefits of acquiring experience working in the household enterprise may grow as the enterprise expands.2
Understanding program impacts on child engagement in productive activities is important because these activities may have implications for child well-being both immediately and in the long run. This paper provides experimental evidence confirming that, in households receiving unconditional cash support, children may work more for the household enterprise. The focus is on large-scale, unconditional, government-run cash transfer programs in Malawi and Zambia. These programs have been selected for the analysis because they target comparable and particularly relevant populations: labor and credit-constrained, ultrapoor, smallholder farmers. The study relies on cluster randomized designs to establish the effects of these programs.
There are differences in program design features across the two countries. Transfer size, for instance, depends on household composition in Malawi, but is flat in Zambia. And, although the core identification strategy (randomization) is the same across the country studies, there are some differences in the evaluation designs. The time between baseline and endline data collection, for example, was two years in Malawi and three years in Zambia. One cannot therefore conclusively explain differences in the evaluation findings for the two countries. There are nonetheless broad similarities in these findings across the two settings, suggesting that the results are relevant more generally for unconditional cash transfer programs targeting similar populations.
As documented also elsewhere (for instance, Handa, Daidone et al. 2018; Handa, Natali et al. 2018), both programs (and other programs in the region) strongly expanded household productive investment and, especially, entrepreneurial activities in agriculture. Adult household members deepened their engagement in the household enterprise and reduced their participation in work for pay outside the household. The reduction in paid work could imply that adults face heavy demands on their time and cannot expand their net labor supply or that they prefer working in the household enterprise. Beneficiary households hired more labor. And children (ages 8–17) increased their work for the household enterprise. In Malawi, children, too, shifted out of work for pay outside the household, a substitution pattern consistent with the findings of previous studies (such as Covarrubias, Davis, and Winters 2012; Prifti et al. 2017), but not observed to the same extent in Zambia.
This study examines whether the programs affected child engagement in productive activities that may have negative consequences for their well-being. It also explores contemporaneous impacts on those domains of child well-being that may be affected by or determined simultaneously with these activities. First, it looks at child engagement in excessive working hours, defined using age-specific thresholds recommended by the International Conference of Labour Statisticians (ILO 2008). While work on the household farm increased in both countries, engagement in excessive hours of productive activities rose only in Zambia. A key concern is that child engagement in excessive working hours may lower school participation. However, both programs raised school attendance. Moreover, relying on a survey module extensively tested by the United Nations Children’s Fund (UNICEF) (Dayıoğlu 2012), the study finds that the program in Malawi increased child exposure to work-related hazards, such as carrying heavy loads and working with dangerous tools. (This information was not collected in Zambia.) Nonetheless, child health in Malawi improved slightly.
The study contributes to the literature on cash transfer programs and child engagement in productive activities.3 Although considerable heterogeneity exists in the conclusions about different programs, most studies find that cash transfers either have no impact or lower child participation in economic activities and household chores.4 A comparatively large literature focuses on cash transfer programs that are conditional on schooling and that have been implemented in Latin America. The most well known is Mexico’s Prospera Program (for example, see Behrman, Parker, and Todd 2009; de Janvry et al. 2006; Skoufias and Parker 2001). However, the evidence is also growing on the effects of unconditional cash transfer programs (for instance, see Edmonds 2006; Edmonds and Schady 2012; Handa et al. 2016; Sebastian et al. 2016). Few studies document the effects of cash transfers on potentially harmful types of child labor, such as long working hours and hazardous work. One exception is Edmonds (2006), who finds that the South African old-age pension significantly decreases child full-time employment, defined as 40 or more hours of paid work a week.5 Another exception is Edmonds and Shrestha (2014), who find that conditional scholarships and school stipends reduce child labor in carpet weaving in Nepal, a sector associated with trafficking and bonded labor. These beneficial effects last only for the duration of the intervention and disappear when scholarships are discontinued.
The remainder of this paper has the following structure. Section 2 provides necessary background information by describing the design of the two programs and the accompanying evaluations. Section 3 supplies the descriptive statistics of the sample, discusses the validity of the evaluations by exploring attrition, balance, and program take-up, and describes the estimation strategy. Section 4 shows how the programs affected household entrepreneurial activities, child work, and child well-being. Section 5 discusses and concludes.
2. Background6
This section provides background on the two programs and information about the evaluation design and the data.
Malawi’s Social Cash Transfer Program
Malawi’s Social Cash Transfer Program (SCTP) is an unconditional cash transfer program that aims to reduce poverty and hunger and to increase school enrollment rates among ultrapoor households. The program is administered by the Ministry of Gender, Children and Social Welfare (MoGCSW) with policy oversight by the Ministry of Economic Planning and Development (MoEPD). The pilot stage of the SCTP, implemented in Mchinji District in 2006, had a wide range of positive impacts, including increased food security, ownership of agricultural tools, and curative care seeking (Miller, Tsoka, and Reichert 2010). Because of these results, the program was rapidly expanded, becoming a key part of Malawi’s social safety net and reaching about 170,000 households across 18 districts by the end of 2015.
The SCTP targets ultrapoor, labor-constrained households. Households are classified as labor constrained if the number of household members, divided by the number of household members who are fit to work exceeds three.7 Households are classified as ultrapoor if they are unable to meet their most basic needs.8 Targeting is carried out in three stages. First, potentially eligible households are identified by village social protection committees based on the stated criteria of ultrapoor and labor constrained. The district commissioners office then administers a targeting survey to these households, and the data are processed at the ministry in Lilongwe to confirm eligibility based on a proxy-means test (for the poverty criterion) and on demographic composition (for the labor-constrained criterion). The final approved lists are then sent back to the district commissioners office for confirmation. The approximate coverage rate is 10 percent of all households in program areas.
Although the SCTP is not conditional on school attendance, transfer amounts vary with the size of the beneficiary households and with the number of primary- and secondary-school-age children (table 1). During the period of the study, the average total monthly value of the transfers among households was about MK 2,571 (US$3.70), which equals 18 percent of the baseline consumption of beneficiary households. Transfers are paid in cash at local pay points every two months. At enrollment, households are told about program rules and regulations; the reason the households were selected; the main objectives of the program (to reduce food insecurity and to support the well-being of children, including their schooling); the initial three-year duration of household participation in the program, after which the participation will be reassessed; and payment procedures and amounts. During the initial three years, benefit amounts are not altered even if there are changes in household composition.

Zambia’s Multiple Category Targeting Program
Zambia’s Ministry of Community Development, Mother, and Child Health has been experimenting with various models of targeted cash transfer programs since 2004. The Multiple Category Targeting Program (MCP) aimed to reduce hunger and support the health, nutrition, and schooling of children. It was introduced as a pilot program in 2011, reaching approximately 10,000 households. In 2015, the government decided to consolidate the country’s various cash transfer programs into a single unified program, and MCP households were retargeted for potential eligibility in the new unified program in late 2015. The policy change and retargeting did not affect the impact evaluation of the MCP that was completed in 2014.
The MCP targeted households falling into one of the following four categories: households headed by a female member and including orphans; households headed by an elderly member (ages more than 60) and including orphans; households with a disabled member; and households with other critical situations (such as households with two elderly members who are unable to support themselves economically). Households were selected by members of the community welfare assistance committees (CWACs), in collaboration with staff from the District Social Welfare Office. Specifically, a short targeting form was administered to all households in the pilot sites to capture information on demographic composition and family relationship status. Information retrieved from these forms was processed at the ministry in Lusaka to produce final eligibility lists, which were shared with the District Social Welfare Office for final approval. There is no poverty criterion for eligibility, but the pilot sites are so poor that 90 percent of eligible households fall below Zambia’s extreme poverty line. Because of the categorical targeting procedure described above, expected program coverage rates are between 10 percent and 15 percent.
The program provided a flat transfer (that is, independent of the size of the beneficiary household) equal to K 55 (about US$12) a month, an amount considered sufficient at the time to provide one meal a day to each household member. The transfer was raised to K 60 in 2012 and K 70 in 2013 to account for inflation; it represented approximately 28 percent of beneficiary preprogram consumption. Transfers were paid in cash at local pay points every two months. Similar to the Malawi program, recipients were told during the enrollment process about the program objectives, rules, payment amounts and payment processes, and that eligibility was for an initial three years.
Evaluation Designs
In both countries, program expansion plans included the integration of cluster randomized evaluations.9 (See table 1 for a summary of the evaluation setup.) In Malawi, 29 village clusters (VCs) in the districts of Mangochi and Salima were randomly assigned to either a treatment or a control (delayed treatment) group. The 29 study VCs were selected in two steps in September 2012. First, within each of the two districts, two smaller geographical areas known as Traditional Authorities (TAs) were randomly selected for the study. The random selection of TAs was carried out by lottery at a meeting of the Social Protection Technical Group, chaired by the ministry. Next, 15 VCs (of 24) in Salima and 14 VCs (of 21) in Mangochi were randomly selected from these TAs to be incorporated in the study. (The number was higher in Salima because the VCs there were smaller.) In each VC, household targeting for participation in the program was carried out between November 2012 and May 2013. The baseline survey was conducted shortly thereafter, between June and October 2013. In Salima, all eligible households in each VC were interviewed. In Mangochi, where the VCs were larger, study households were randomly sampled from the eligibility lists. In November 2013, shortly after completion of the baseline survey (see below), VCs were randomly assigned to the treatment or control groups by coin toss held publicly in the district commissioners office in each district, resulting in a total of 14 VCs entering the program immediately.10 The remaining VCs were told that they would eventually enter the program, the exact date to be determined. Households in these VCs were not told their eligibility status until the VCs entered the program, which was after the study ended. The disbursement of transfers in treatment VCs commenced in December 2013.
Many features of the design of the impact evaluation in Zambia resemble those of the impact evaluation in Malawi. A total of 92 CWACs in the districts of Luwingu (Northern Province) and Serenje (Central Province) in Zambia were randomly allocated to a treatment and a control group. In June 2010, the Ministry of Community Development, Mother, and Child Health selected 46 CWACs per district by means of a public lottery involving district and provincial officials. From January to September 2011, households in these CWACs were targeted for participation in the program. More than 100 eligible households were identified per CWAC, and the study team randomly selected 33 of these households for incorporation in the impact evaluation based on the desired sample size derived from power calculations. The baseline survey was conducted between November and December 2011. Shortly after the finalization of the baseline survey (see below), the ministry assigned an equal number of study CWACs to the program group or a control group by means of a public coin toss in each district, following a process identical to the one in Malawi. The first transfers were paid out in February 2012.
Data and Outcome Variables
Both evaluations rely on information collected through surveys administered to a knowledgeable household member.11 In Malawi, baseline data were collected from 3,531 eligible households from July to September 2013. The same households were reinterviewed at endline, between October and November 2015. In Zambia, baseline data from 3,078 eligible households were collected from November to December 2011. Endline data were collected in the same period of 2014. (See table 1 for an overview of the evaluation timelines.) In both countries, the questionnaire module on child productive activities was particularly extensive at endline. The study involved the use of this information to construct variables for (hours of) participation in economic activities in the seven days prior to the interview and in household chores in the day prior to the interview.12
In Malawi, the evaluation examined four categories of economic activities carried out by children in the week prior to the endline survey: farmwork for the household (excluding livestock), caring for livestock owned by the household, work in the nonfarm household business, and paid work outside the household (including formal wage work and informal piecework). And the evaluation examined three categories of household chores carried out in the day prior to the endline survey: collecting water or firewood; taking care of children, cooking, or cleaning; and taking care of elderly or sick household members.13 Measures of the combined involvement of children in economic activities and household chores were also constructed.
In Zambia, it has been possible to construct mostly comparable outcome variables. However, there are two categories of productive activities for which no information was collected: farmwork for the household and taking care of elderly or sick household members. In Zambia, the household questionnaire also collected data on individual participation and hours worked in any paid work and unpaid work (the latter including household chores) during the two weeks before the interview. This information was available both at baseline and endline, and it has been used to establish baseline balance. The remaining outcome variables are described in the supplementary online appendix, table S1.
3. Empirical Strategy
The section supplies descriptive statistics of the sample, discusses the validity of the evaluations by exploring attrition, balance, and program take-up, and lays out the estimation strategy.
Sample and Descriptive Statistics
The regression sample is restricted to children on whom there is complete information at baseline and endline. In Malawi, the sample is further restricted to children ages 6–15 at baseline. The lower age limit is set at 6 because data on engagement in economic activities and household chores were collected from this age. The upper age limit is set at 15 to ensure that the individuals in the sample are minors at follow-up, two years after the baseline. In Zambia, the sample is restricted to children ages 5–14 at baseline. Because Zambia endline data were collected three years after the baseline, endline ages correspond with those in Malawi and range from 8 to 17 in both countries. The regression analysis consistently applies these restrictions so that each regression used to assess the impacts of the program on child activities is estimated on the same sample of children.14 The baseline sample size is 6,733 and 4,816 for Malawi and Zambia, respectively. By endline, these samples had been reduced to 5,806 and 3,999 children, implying an average attrition rate among individuals of about 14 percent and 17 percent, respectively.
Tables 2 and 3 describe the baseline characteristics of the households and children in the samples in Malawi and in Zambia, respectively. Among households, tables 2 and 3 examine the determinants of program eligibility (panels a and b), the determinants of transfer size (panel c), and outcome variables (panel d). At the level of the child, the tables examine demographics (panel e) and outcome variables (panel f). In both tables 2 and 3, column (1) reports baseline mean values for the control group in the full sample of children (and related households) as observed at baseline. This information is used to describe the sample. Baseline balance and differential attrition are discussed in the next subsection.

Poverty and food consumption:
The sample households are ultrapoor. The baseline daily per capita consumption of households eligible to benefit from the cash transfer programs under study was equal to approximately US$0.35 in both countries (not displayed).15 Concomitant with low consumption, the clear majority of households in both countries occupied basic dwellings with floors and roofs made of natural materials (mostly sand, mud, or grass). It was not uncommon for household members to live on one meal a day (21 percent and 27 percent in Malawi and Zambia, respectively), and most households survived at least partly on assistance, such as cash or food aid (72 percent and 60 percent, respectively).
Credit constraints:
About 28 percent and 16 percent of the control households in Malawi and Zambia, respectively, had borrowed money in the year prior to the endline interview. (See online appendix, table S2 for more detail.) Households that borrowed money primarily did so to support consumption and health expenditures. Only 2 percent and 3 percent of households in Malawi and Zambia, respectively, had borrowed money to invest in the farm or nonfarm business, and, in both countries, only 2 percent of households had borrowed money to finance education expenditures. Households mostly borrowed from relatives, neighbors, and friends (67 percent and 84 percent of the control households, respectively).
Livelihoods:
A large majority of households in both countries owned or cultivated land (97 percent and 92 percent, respectively). However, the area of land owned or cultivated was small (respectively, an average of about 2 and 1 hectares in Malawi and Zambia). Among more than half the households in Malawi, the harvested maize—the staple crop in Malawi—lasted for less than four months (not measured in Zambia). Livestock ownership was less common in Malawi than in Zambia (24 percent vs 58 percent). It was also less common for households in Malawi to sell livestock (7 percent vs 19 percent). In Malawi, about 24 percent of households ran nonagricultural enterprises (not measured in Zambia).16 The monthly profits of these enterprises were low: an average of about US$11 a month for households reporting that they ran nonagricultural enterprises.
Household composition:
Most households (88 percent and 71 percent in Malawi and Zambia, respectively) were labor constrained (see section 2). In both countries, the majority of households each had nearly four members below the age of 21. Possibly because of differences in targeting criteria across the two countries, there were dissimilarities in household composition between the two countries. InMalawi, over half the household shad one or more disabled members. In Zambia, this share was lower, at 26 percent. InMalawi, respectively, 21 percent and 14 percent of households hosted orphans and were headed by a female or by an elderly person. In Zambia, the latter two categories (female or elderly headed) were more common, at 57 percent and 29 percent.
Children:
In both countries, children were about 10 years old on average at baseline. About 73 percent and 66 percent of children in Malawi and Zambia, respectively, were in school. Children had completed about 2.5 and 1.8 grades of education, on average. Although the baseline indicators are somewhat limited, the available information suggests that it was quite common for children in both countries to engage in economic activities and household chores. In Malawi, 1 percent of children cared for livestock; 5 percent supported a household nonagricultural business; and 9 percent engaged in economic activities for pay outside the household. About 43 percent and 35 percent of children collected water or firewood or helped by taking care of children, cooking, or cleaning. In Zambia, about 1 percent engaged in economic activities for pay outside the household, and 68 percent carried out unpaid economic activities and household chores.
Attrition and Balance
The evaluations examined whether the attrition rate among children was affected by the programs. This was accomplished by regressing the indicator for attrition on the indicator for living in a treated village and on the stratification variables, that is, the four TAs in Malawi and the two districts in Zambia. The results are reported in tables 2 and 3, column (2), panel g, for Malawi and Zambia, respectively. In the treatment group, point estimates are about 2 and 3 percentage points higher in Malawi and Zambia, respectively, but this difference is not statistically significant.
Tables 2 and 3 examine balance in the baseline characteristics of all households and children observed at baseline (column (2)), households and children that could not be reobserved at endline (the attritor sample, column (3)), and households that could be reobserved (the panel sample, column (4)). There are generally few differences observed in the baseline characteristics of households in the control and treatment clusters. In both countries, there is a small but statistically significant difference in child age. In Malawi, children in the treatment group are slightly older than those in the control group, and vice versa in Zambia. There is no clear explanation for this difference. The regressions include age fixed effects, thereby limiting concerns that age differences may drive impacts on child work.
The most salient and important violation of baseline balance occurs in the case of Zambia, where children in treatment clusters had significantly worse educational outcomes than children in control clusters. In the full baseline sample and in the panel sample, they were about 6 percentage points less likely to attend school and had completed about 0.3 fewer school grades (table 3, column (2), panel f). This finding appears to be a statistical coincidence because the experiment in Zambia was balanced on most other domains captured at baseline (see also Seidenfeld, Prencipe, and Handa 2012). Work for pay within Malawi’s attritor sample is not balanced either (table 2, column (3), panel f). The joint test of orthogonality does not reject the null hypothesis that the baseline variables are jointly orthogonal to the treatment, providing support to the internal validity of the estimates (tables 2 and 3, panel f).
The baseline characteristics of children in the panel sample differ from those of attritors in a few respects (see online appendix, table S3). For example, in both countries, panel children were significantly younger than children who attrited, presumably because older children are more likely to move out of the household. The findings represent program impacts only on the sample of children that could be observed at endline, and impacts may not be identical among children who could not be tracked.
Program Take-Up
In Malawi, nearly all households (99 percent) in the treatment clusters reported that they were program beneficiaries (online appendix, table S4). Among these households, 96 percent had received transfer payments in the three months prior to the endline interview. In the control clusters, effectively none of the households reported that they had received transfer payments.17 In Zambia, the share of households reporting at endline that they were beneficiaries was lower, at 75 percent. Among these households, 95 percent had received transfer payments in the three months prior to the endline interview.18 The share of households reporting program receipt in control clusters was 2 percent.
In Malawi, beneficiary households were asked how they spend the transfers. They indicated they spend the transfers on immediate priorities such as food, clothing, and health care, but also commonly reported they invested in education (56 percent), livestock (31 percent), or agricultural inputs (23 percent) (online appendix, table S4).19
Regression Specification
Because many of the outcomes of interest are only measured at endline, the study mainly relies on cross-sectional regressions estimated based on data from the endline surveys. The robustness of the results is tested using a variety of alternative specifications, as described below.
The main cross-sectional specification is as follows:
| (1) |
where Outcomeiv represents the outcome variable for household (or individual) i living in cluster v. The term Tv is a dummy variable equal to 1 if the cluster in which the household or individual is located received the transfer program. Xiv is a vector comprised of a small set of baseline control variables, including fixed effects for the stratification variables and fixed effects for the enumerators who carried out the interviews.20 For individual-level regressions, the control variables also include gender and age fixed effects. For Malawi, there are also controls for the determinants of transfer size as measured at baseline (table 2, panel c). εiv is the error term.
In all regressions, standard errors are clustered at the unit of randomization (village cluster in Malawi; the CWAC in Zambia). To account for the low number of village clusters in Malawi, p-values are estimated using the wild bootstrap method (Cameron, Gelbach, and Miller 2008).21 The coefficient of interest is β2, which represents the impact of the transfer on household and individual outcomes. Given nonuniversal take-up, the estimated impacts in Zambia should be interpreted as intent-to-treat effects. In Malawi, where take-up was effectively universal, the intent-to-treat effect is equal to the average effect of treatment on the treated.
4. Results
This section examines the effects of the programs on household entrepreneurial activities, child work, and child well-being.
Household Entrepreneurial Activities
Consistent with Handa, Daidone et al. (2018), the study finds that the two programs enabled households to expand their agricultural enterprises substantially. Beneficiary households were 2 and 9 percentage points more likely to own or cultivate land in Malawi and Zambia, respectively (table 4). The area of land owned and cultivated increased by approximately 9 and 10 percent. The probability that households sold crops rose by 11 and 16 percentage points. The impacts on livestock ownership and sales were even more pronounced. In Malawi, the probability that households owned and sold livestock both more than doubled because of the program (an increase of 34 and 8 percentage points, respectively). In Zambia, the ownership and sale of livestock increased by 27 and 7 percentage points, respectively.22 In Malawi, there was also an increase in the likelihood that households run a nonagricultural business (12 percentage points). Monthly profits from these businesses rose by about US$4 for the average household, indicative of a markedly larger increase among households with active enterprises. In Zambia, the point estimate for household engagement in nonagricultural businesses, while positive, is smaller and not statistically significant. A possible explanation is that study sites in Zambia were more isolated than those in Malawi, with fewer opportunities for engagement in nonagricultural businesses. (Zambian households in the control group were significantly less likely to be operating a nonagricultural business than those in Malawi, 9 percent vs 21 percent.)

In both countries, adults increased their engagement in household enterprises accordingly, while simultaneously lowering their engagement in work for pay outside the household (table 5). In Malawi (Zambia), adults increased their participation in nonlivestock agricultural activities by 12 (5) percentage points, livestock herding by 13 (3) percentage points, and work in nonagricultural businesses by 3 (3) percentage points. Paid work outside the household decreased by 12 (6) percentage points. As a result, program impacts on the net engagement of adults in economic activities were limited in both countries. The point estimates for engagement in economic activities are 2 and 3 percentage points in Malawi and Zambia, respectively; only the latter was statistically significant. These findings could imply that adults face heavy demands on their time also in the absence of the program and cannot substantially expand their labor supply. In Malawi, adults also boosted their engagement in household chores (not measured in Zambia). Some of these activities, such as collecting water and firewood (which increased by 5 percentage points), may play a role in the expansion of the household enterprise.

Households hired more labor to support the expansion of household entrepreneurial activities. During the agricultural season before the endline interview, beneficiary households in Malawi and Zambia were, respectively, 5 and 18 percentage points more likely to hire help to work on the household farm, that is, hired labor roughly quadrupled relative to the control group (table 4). The data do not allow to establish whether labor market imperfections prevented households from hiring even more labor.
The findings favor the interpretation that, because of poverty and credit constraints, households were limited in their capacity to invest in household enterprises. The introduction of the cash transfer programs enabled households to boost their productive investment. Handa, Natali et al. (2018) study the effects of the MCP and another cash transfer program in Zambia on long-term living standards, including productive activities, in more detail. They show that these investments resulted in substantial multiplier effects, allowing households to raise their expenditure and investments beyond the value of the transfers, which helps explain the drastic expansion in household productive activities. Households accommodated the expansion of the household enterprise by reallocating adult labor and recruiting on local labor markets. Children also increased their work in the household enterprise.
Children’s Productive Activities
Child engagement in nonlivestock agricultural activities rose by 6 percentage points in Malawi (not measured in Zambia) (table 6). Caring for livestock more than doubled, increasing by 7 and 4 percentage points in Malawi and Zambia, respectively. Support among children for household nonagricultural enterprises was unaffected in Malawi, but expanded by 3 percentage points in Zambia. In Malawi, mirroring the findings on adults, children shifted away from economic activity for pay outside the household (a reduction of 6 percentage points). In Zambia, where children were less likely to engage in economic activities for pay to begin with, no such shift was observed. A potential explanation for this difference is that the study sites in Zambia were more isolated than those in Malawi, with fewer opportunities for engagement in nonagricultural businesses and work outside the household. Accordingly, the probability that children were engaging in any economic activities did not change significantly in Malawi (point estimate of +3 percentage points), while it increased significantly, by 6 percentage points, in Zambia.23

For Malawi, regressions also include controls for household composition (dummy variables for whether the household includes 3 members, 4 or more members, number of members below 21 years of age, number of members between 21 and 29 years of age). P-values in brackets, estimated using the wild bootstrap method (parameters: 999 replications, Rademacher weights), clustering at the unit of randomization level (village cluster for Malawi, Community Welfare Assistance Committee for Zambia).

Both programs also increased child engagement in household chores. Children in Malawi and Zambia were, respectively, 10 and 3 percentage points more likely to collect water or firewood. And, in Malawi, children were 9 percentage points more likely to care for other children, cook, and clean. Some of these household chores may contribute directly to the household enterprise; others may do so indirectly, by relieving adults of some duties.24
Robustness Checks
This section explores robustness to using attrition corrections and randomization-based inference.25 It first examines the attrition corrections. Online appendix, table S7 shows Horowitz-Manski bounds (Horowitz and Manski 1998). Lower and upper bounds are obtained by estimating regression specification (1) on the full sample of children present at baseline, imputing outcome values for attritors according to the two most extreme possible scenarios. The most extreme scenarios correspond to assigning the values 0 to all attritors from the treatment group and 1 to all attritors from the control group or vice versa. The Horowitz-Manski bounds are wide and comprise zero for all outcome variables. Hence, strong differences in the outcomes for attritors by treatment status could render the estimates invalid.
The findings are robust to correcting for attrition using inverse probability weights (Fitzgerald, Gottschalk, and Moffitt 1998). The predicted probability that children are observed at follow-up was obtained based on equation (1), but with the term X augmented to include all the covariates in table 2. The weights are obtained as the inverse of this probability. The weighted point estimates and significance levels reported in table 7, columns (1) and (3) are effectively unchanged relative to the original estimates displayed in table 6.

The results are robust to bounding treatment effects in the spirit of Lee (2009). The control panel sample, which had a lower attrition rate, was trimmed so that the attrition rate equals the rate in the treatment group.26 To obtain the upper bound of the treatment effect, the control group was trimmed by randomly removing children with outcome variables equal to 1. To obtain the lower bound, the trim involved randomly removing children with outcome variables equal to 0. Regression (1) was then reestimated on these trimmed samples. As expected given the small difference in attrition rates among treatment groups, these bounds are sufficiently narrow for most of the originally statistically significant program impacts to remain significant (online appendix, table S7). The only exceptions occur in the case of Zambia, in which the lower bounds for the collection of water and firewood and for participation in any economic activities or household chores have the same sign as the original estimate, but are no longer statistically significant.
The findings are also robust to using randomization inference (table 7, columns (2) and (4)). Following Fujiwara and Wantchekon (2013), treatment status at the original level of randomization is randomly reassigned, and the impact of this placebo treatment is estimated using specification (1). This procedure is repeated 1,000 times to obtain p-values, which equal the proportion of reestimated impacts that are larger in absolute value than the original estimated impact.27
Child Well-Being
This subsection examines whether the programs affected child engagement in productive activities that may have negative implications for child well-being. Those domains of child wellbeing are explored that may be affected by or simultaneously determined with these activities.
Excessive working hours:
At low levels of intensity, child engagement in common economic activities and household chores may be innocuous or beneficial to children. However, long hours in these activities may have negative implications. The study therefore tested the program impacts on excessive working hours. Because the appropriate number of working hours depends on the age of the child, the focus is on three age-groups recommended by the International Labour Organization (ILO 2008): under 12, 12–14, and 15–17. Within these age-groups, ILO (2008) recommends, respectively, applying the following thresholds to establish excessive hours of economic activities: 1, 14, and 43 hours per week. For all age categories, ILO (2008) suggests a threshold of 28 hours for household chores.
In Malawi, children in the two older ILO age-groups (12–14 and 15–17) had increased their engagement in economic activities by about 5 to 6 percentage points by endline. (The point estimate for older children is not statistically significant; see table 8, panel a, columns (1)–(3)). Among children in the youngest ILO age bracket (under 12), the point estimate is small and not significant. Children in all age-groups increased their engagement in household chores, although, at 13 percentage points, this increase appears especially strong among younger children. In Zambia, children in all age-groups increased their engagement in economic activities by about 5 to 6 percentage points (table 8, panel a, columns (4)–(6)). Engagement in household chores rose only among older children, by about 5 percentage points.

Notes:
Regular school attendance is defined as follows. Malawi: the child did not miss more than two consecutive weeks of school during the 12 months before the interview. Zambia: the child attended five days of school during the week before the interview (lower number of observations, due to children in boarding schools or children who were on holidays during the week before the interview). In Panels A and B, regressions are obtained by using the endline data and estimating regression specification (1) on subsamples by age group. In Panel C, regressions are obtained by using both the baseline and the endline data and estimating a difference-in-differences specification, on subsamples by age group. Hence, the number of observations used for Panel C regressions is double the number displayed in the table. The sample includes children aged 6-15 and 5-14 years at baseline, in Malawi and Zambia respectively (8-17 years at endline in both countries). Regressions include fixed effects for gender, age, stratification variable (Traditional Authority for Malawi, district for Zambia) and enumerator. For Malawi, regressions also include controls for household composition (dummy variables for whether the household includes 3 members, 4 or more members, number of members below 21 years of age, number of members between 21 and 29 years of age). P-values in brackets, estimated using the wild bootstrap method (parameters: 999 replications, Rademacher weights), clustering at the unit of randomization level (village cluster for Malawi, Community Welfare Assistance Committee for Zambia).

In Malawi, there is no evidence that program receipt encourages child engagement in excessive hours performing economic activities and household chores (table 8, panel b). These findings (1) are explained by a shift away from work for pay outside the household, which leaves net engagement in economic activities in the younger age-group unaffected, and (2) suggest that children who engage in household chores in response to the program do so at modest intensity. In Zambia, we do observe a rise in excessive engagement in economic activities and household chores of 5 to 6 percentage points in all age-groups. For younger children, this increase is driven primarily by greater engagement in economic activities, while, among the two older age-groups, the increase is driven by excessive engagement in household chores. However, cumulative density functions suggest that changes in the hours doing household chores may not have been drastic for children who were pushed over the 28-hour threshold. (The results are available upon request.)
Education outcomes:
A key concern is that increased child engagement in economic activities, household chores and, particularly, excessive hours may interfere with schooling. Therefore, table 8, panel c, examines program impacts on education. Because education outcomes were not balanced at baseline in the case of Zambia, difference in differences estimates are shown for the impacts on education. Program impacts on school attendance are positive, and the impacts are larger among older children, who are at higher risk of dropping out. In Malawi, school attendance rose by about 8 percentage points among the two lower age-groups and 15 percentage points among the older age-group. In Zambia, school attendance increased by 7 and 8 percentage points, respectively, among the older age-groups, while it did not increase significantly among the youngest age-group. In Malawi, there was a transfer top-up precisely to support school-age children, which could explain the larger impacts. Changes in education expenditures broadly correspond with the impacts on school attendance. The expansion in school attendance is driven by a drop in the share of children who are out of school because of a lack of the ability to pay for education.
The results here are consistent with the review by Handa, Daidone et al. (2018), who show that six of the eight cash transfer programs in Sub-Saharan Africa (including the ones studied here) increased school enrollment among secondary-school-age children. The results are also consistent with the program impacts on schooling outcomes presented by Kilburn et al. (2017) on Malawi and Handa, Natali et al. (2018) on Zambia. Kilburn et al. analyze the short-term impact of Malawi’s SCTP on education outcomes, relying on the same experimental setup and using midline data collected one year after the start of the program. They find that the program raised school enrollment and reduced dropouts. An increase in household spending on education (uniforms and school supplies, in particular) is proposed as the key mechanism driving the observed impacts.28
The study here does not find that the effects of the transfers on the highest grade of education completed in either Malawi or Zambia were statistically significant.29 There are multiple plausible explanations for the lack of impact on grade progression. One possibility is that the children who enter school because of the programs are disadvantaged students who do not progress so easily. Results from conditional cash transfer programs in Brazil, Colombia, and Mexico confirm that school achievement is lower among age-groups among which there are enrollment effects (Behrman, Sengupta, and Todd 2000; de Janvry et al. 2006; Garcia and Hill 2010). Beyond student selection, the study locations are extremely poor, and school quality is low; so, simply sending children to school may not necessarily raise achievement in this context. A final possible explanation is that program-induced participation in (excessive hours of) economic activities and household chores slowed grade progression.
A dedicated, embedded qualitative data collection exercise on child labor was implemented in Malawi in June 2016, that is, about a half year post-endline. In-depth interviews and focus group discussions were held with youth, caregivers, and teachers in eight treatment villages. A full discussion of the qualitative findings can be found in Zietz, de Hoop, and Handa (2018). Because they confirm and help to contextualize and interpret the quantitative findings, the qualitative findings related to work and school attendance are briefly discussed here.
Caregivers, youth, and teachers all identified potential interference with school as the main negative aspect of child engagement in household chores and economic activities. All three groups of respondents discussed instances of children not attending school or reducing their effort in school because of obligations to provide for their households. Caregivers, however, generally indicated that they prioritize child engagement in economic activities only in situations of severe and acute need. Moreover, caregivers generally perceived school attendance as important and indicated that prioritizing children’s engagement in economic activities causes feelings of guilt and regret. The latter may explain why, in the quantitative analysis, an increase in work on the household farm did not appear to deter school attendance.
Types of economic activities:
For well-being, the implications of child engagement in productive activities depend not only on working hours, but also on the type of activities in which children engage. Children in Malawi shifted away from work for pay outside the household into work for the household enterprise. A decomposition in the main analysis sample reveals that the category “paid work outside the household” consists almost entirely (97 percent) of ganyu labor, that is, informal piecework at low pay. Ganyu is the option of last resort among the very poor. Indeed, other studies examining the effects of the SCTP on mental well-being suggest that a reduction in ganyu is associated with a significant reduction in indications of depression among adolescents (Angeles et al. 2017). Hence, a reduction in paid work represents an improvement among children.
Engaging in economic activities may also be problematic if it exposes children to hazards that may affect their physical or mental health. Based on Malawi endline data—information on hazards was only collected in Malawi at endline—and relying on a UNICEF survey module extensively tested by Dayioglu (2012), an investigation was conducted on the effects of exposure to four hazards during engagement in economic activities and household chores: carrying heavy loads; working with dangerous tools; exposure to dust, fumes, or gas; and exposure to extreme cold, heat, or humidity.30 Malawi’s SCTP increased the likelihood that children engage in any of these hazardous activities by 4 percentage points (relative to 25 percent among children in control villages) (table 9). Exposure to all four individual hazards rose significantly.

To understand more clearly what drives the observed increase in hazardous work, the study relied on data on the control villages and, within these, compared the prevalence of hazards between children who participated in any economic activities during the week before the interview and those who did not. Exposure to hazards is nearly 80 percentage points higher in the first group than in the second (online appendix, table S9). Thus, the economic activities in which children engage in this setting inherently entail the four measured hazards, and changes at the extensive margin result in almost one-to-one changes in exposure to hazards.
Health outcomes:
Increased exposure to hazards did not translate into more illness and injury in the short term. The program in Malawi slightly reduced illness during the 12 months prior to the endline survey (bottom of table 9), suggesting that, in the short run, any negative effects on health because of work-related hazards may be offset by positive income effects.31 Of course, the economic activities carried out by children may have longer-term implications not captured by this study.
The qualitative findings presented in Zietz, de Hoop, and Handa (2018) help in understanding the hazards measured in the endline survey. Children carry heavy loads when they collect water and firewood for the household, when they harvest maize and sugarcane on the household farm, and when they transport sand and water while making bricks for pay. Dangerous tools are mostly limited to panga knives and shovels, while the use of heavy machinery is not reported. Children are exposed to dust when they farm on dry land and sweep the floor in and around the household dwelling, which can result in coughs and breathing problems. Children are also exposed to smoke, while cooking, for instance. There was some mention of exposure to extreme heat because of farmwork in the midday sun and exposure to extreme noise when working near maize mills. Injuries were regularly reported, but they tended to be minor.32 These qualitative observations help explain why an increase in hazards does not translate into a deterioration in health outcomes in the quantitative data.
5. Concluding Discussion
This paper examines the potential cascading effects on children of increased investment in the household enterprise induced by unconditional cash transfer programs. The focus is on cash transfers provided to ultrapoor, labor- and credit-constrained households in Malawi and Zambia. In both countries, cash transfers resulted in an expansion of (mainly agricultural) household microentrepreneurial activity. Households accommodated the expansion of the household enterprise by reallocating adult labor supply and hiring external labor. Children, too, began to work more on the household farm. In Malawi, the increase in child work on the household farm was offset by a reduction in work outside the household for pay. In Zambia, no such reduction was observed, possibly because the areas studied in Zambia are particularly remote and far from markets and trading centers. Limited opportunities to work outside the household for pay likely reduced the margin for program impact on these types of economic activities.
The implications for child well-being of increased work on the household farm cannot be fully captured. In Zambia, child engagement in excessive working hours, defined using age-specific thresholds, increased. In Malawi, because of the offsetting reduction in work for pay outside the household, no such increase is observed. Both programs raised school attendance. However, the study did not measure longer-term indicators of human capital accumulation, such as learning in school and progression to higher education levels. The study also did not explore how increased work on the farm, along with school attendance, affected child leisure and sleep, critical elements of child well-being and development.
The program in Malawi increased child exposure to work-related hazards, such as carrying heavy loads and working with dangerous tools. Nonetheless, contemporaneous indicators of child health improved slightly in Malawi, suggesting that positive income effects may have outweighed the implications of exposure to hazards in the short run. Indeed, both programs substantially improved nutrition outcomes and indicators of child material well-being, such as ownership of a pair of shoes, possessing two sets of clothes, and sleeping under an insecticide-treated mosquito net (AIR 2016; UNC 2016). However, some negative health consequences of hazardous work may become manifest only in the longer run, for instance, the effects of exposure to toxic materials or back injuries resulting from carrying heavy loads at an early age. Because the study observed both positive and potentially negative changes in the lives of children, it reached no definitive conclusion about the net effect of these programs on child well-being.
The study did not conclusively establish the exact reasons children work more in the household enterprise. Here, we briefly reflect on plausible mechanisms. First, adults in beneficiary households may have limited ability to expand their net labor supply. Both programs target households with few able-bodied adults. While both programs increased adult work in the household enterprise, this increase was largely offset by a decrease in work for pay outside the household. The latter could imply that adults already face heavy demands on their time and cannot expand their net labor supply.
Second, while beneficiary households hire more labor, it nonetheless seems plausible that the recruitment of external labor is hampered by labor market imperfections, such as seasonality in agricultural production, which can lead to shortages on the labor market when households need additional hands (Rosenzweig 1988). Furthermore, hired labor and family labor may notbe perfect substitutes (de Janvry, Fafchamps, and Sadoulet 1991; Taylor and Adelman 2003). Bhalotra and Heady (2003, 198), for example, suggest that “the problem of moral hazard with hired labor may generate preference for family labor.”
Third, the enterprises run by program beneficiaries typically require skills obtained outside the formal education system. The importance of these skills may grow as the household enterprise expands, as suggested, for instance, by Bhalotra and Heady (2003). Early engagement in the household enterprise may be a way to acquire these skills and, hence, a reason for children to work. The quantitative surveys do not capture on-the-job learning. However, participants in the qualitative interviews mentioned that work in the household enterprise is important to skill formation. Thus, in relation to the acquisition of farming skills, a 15-year-old girl mentioned that, “if we were to just sit and watch the parents do it, we could be in trouble in future after the parent’s passing” (Zietz, deHoop, and Handa 2018, 250). Finally, liquidity constraints extend the shadow price of inputs that require cash payments, such as hired labor, making it more efficient to rely on family labor to expand productive activity (Singh, Squire, and Strauss 1986). The study areas are mostly in remote locations, and households have little contact with the market economy. It is plausible that having cash is valuable for these households, limiting their willingness to spend it on hired labor.
The main policy implication of this study is that programs resulting in expanded household productive activities need to take the potential implications for children seriously. As shown here, even in cash transfer programs, which are widely considered an important tool for supporting poor and vulnerable children, the implications for child well-being are not obvious. The same holds for programs that have the explicit objective of expanding household entrepreneurial activity. Monitoring changes in children’s time use and the implementation of complementary interventions, such as the provision of information on the importance of schooling, should be considered in conjunction with these programs.
Future studies might consider using outcome variables beyond the time-use indicators used in this study. Besides their effect on schooling, excessive hours of work and chores may also affect the time available for other activities, such as play and sleep. And, if direct interviews with children are feasible, measures of psychosocial well-being and affect should also be considered as a tool for capturing mental health. In programs that strongly affect long working hours, it would be helpful to use additional indicators that capture performance in school and a broader spectrum of child activities. Furthermore, a generic module for the measurement of hazardous activities, such as the one used in this study, may miss relevant work-related hazards. The measures of hazards used in quantitative surveys could be adapted to reflect more closely the hazards that are most relevant among children in a study population. Moreover, while child engagement in work and chores may have negative effects, it may also have benefits, such as on-the-job learning. A better view on the benefits of child engagement in work and chores could improve understanding of the impact of policy interventions on child well-being. More could be done to understand how changes in household production technology affect the child’s experience in supporting the household enterprise, including exposure to hazards and opportunities for on-the-job learning.

Footnotes
For a broader review of the literature on social protection and asset formation, see Hidrobo et al. (2018).
Accordingly, a nonexperimental literature finds that child labor may increase with household farmland in extremely poor rural settings. For a discussion, see Basu and Tzannatos (2003); Edmonds (2007); Fors (2012). For recent examples, see also Basu, Das, and Dutta (2010); Dumas (2013); Oryoie, Alwang, and Tideman (2017). Several recent papers find that the expansion of nonagricultural household enterprises may boost child engagement in household chores and economic activities. Augsburg et al. (2012), for example, find that microcredit in Bosnia led borrowers to expand their household businesses and increased the labor supply of older children. Nelson (2011) documents a similar pattern in a microcredit program in Thailand.
For a discussion of this literature, see Dammert et al. (2018); de Hoop and Rosati (2014); Fiszbein and Schady (2009). This paper also links to the literature on cash transfers and schooling. For literature reviews, see Baird et al. (2014); Fiszbein and Schady (2009); Handa and Davis (2006); Saavedra and Garcia (2012). Moreover, the study relates to the literature on the impact of capital (grants) on microentrepreneurial activities. See de Mel, McKenzie, and Woodruff (2014); Green et al. (2016); McKenzie, Assaf, and Cusolito (2017).
An exception is de Hoop et al. (Forthcoming), who show that Pantawid Pamilia, a large-scale conditional cash transfer program in the Philippines, raised child participation in economic activities for pay. The authors suggest that transfers that were provided conditional on children’s school participation did not cover the (average) direct cost of education. Children who start attending school end up working more to make up for the cost differential.
Edmonds (2006) explains that the reduction in child work is consistent with liquidity constraints because the timing of the pension is fully anticipated.
The descriptions of program and study design draw heavily on AIR (2016); Seidenfeld, Prencipe, and Handa (2012); UNC (2014, 2016).
According to the program’s operation guidelines, the concept of fit to work is operationalized as household membeis who are 19–64 years of age who do not have any illnesses or disabilities, and, for those members ages 19–25, who are not in school.
A household is classified as ultrapoor if any of the following conditions is verified: (a) the household has an average of only one meal a day, (b) the household survives from begging, (c) the household is undernourished, (d) the household does not possess any valuable assets, and (e) the household does not receive any monetary help, food, or gifts from others.
The evaluation of Malawi’s SCTP was implemented by the University of North Carolina at Chapel Hill and the Center for Social Research of the University of Malawi, with the technical support of the UNICEF Office of Research–Innocenti and the Food and Agriculture Organization of the United Nations. The evaluation of Zambia’s MCP was conducted by the American Institutes for Research, with the technical support of UNICEF Innocenti.
VCs were randomly ordered in each district, and the coin toss determined whether the top half or the bottom half of the list would enter the program immediately. The public coin toss was important so that all TAs understood that they had an equal chance of entering the program early and could explain this to their constituents.
Several additional data collection efforts were undertaken as part of each evaluation, but this study does not depend on them. These include midline quantitative data, direct interviews with adolescents and youth (Malawi only), community questionnaires, and embedded qualitative interviews.
In Malawi, the endline questionnaires were administered directly before the start of the lean season, while, in Zambia, they were administered during the lean season. Because the intensity and the type of economic activities vary across seasons, the study also explored indicators of child economic activities during the year before the survey (see section 4, robustness checks). The lean season is the period of the year when, for example, food supplies become scarcer because of the lull between harvest and planting or between planting and harvest.
Our classification partially deviates from ILO (2008), which classifies “collecting water of firewood” as an economic activity.
Whenever this paper presents findings on households, the reference is to households with relevant sampled children.
For calculations, see Seidenfeld, Prencipe, and Handa (2012); UNC (2014).
Reported businesses at baseline were mainly petty trading (46 percent), selling charcoal or firewood (29 percent), and selling craft goods (14 percent). Other, less common businesses included home brewing, taxi and transportation services, and hospitality (bars and restaurants).
At endline, the government of Malawi had enrolled 95 percent of households in control clusters as part of the expansion of the program. However, these households had not yet started receiving transfer payments.
If reported household beneficiary status one year earlier (measured as part of a midline survey) is taken into account, this share rises to 90 percent. These self-reported figures are slightly at odds with information from the ministry. While no household refused the offer of the transfer at the launch of the program, some child-headed households graduated from the program, and some households no longer fulfilled other demographic eligibility criteria. However, ministry records suggest that this figure is closer to 10 percent than to the 25 percent calculated on the basis of self-reports.
In Zambia, information on how households spent the transfers was collected only at midline, showing the most substantial increases in the same expenditure categories.
Enumerator fixed effects improve the precision of the estimates, particularly in Zambia, without substantive implications for the point estimates.
After regression specification (1) is estimated with standard errors clustered at the unit of randomization, the Stata boottest command is applied on the null hypothesis of zero treatment effect (default parameters: 999 replications, Rademacher weights).
Ownership of livestock may be not only a productive investment, but also a way for households to store value in the absence of access to savings instruments. Although impacts on livestock are large at the extensive margin, these impacts do not necessarily reflect drastic increases at the intensive margin. For instance, in Malawi and Zambia, the average number of chickens owned by households in the sample rose by 1 and 2, respectively. The average number of goats and sheep owned increased by 0.5 and 0.6, respectively. Impacts on other types of livestock are more limited. (The results are available on request.)
Online appendix, table S5 shows the impacts on the hours worked by children. The findings are qualitatively similar to those at the extensive margin and confirm that children augmented their engagement in work in household enterprises. In Malawi, this increase was offset by the reduction in hours worked outside the household for pay, leaving net working hours unaffected. In Zambia, engagement in economic activities was up by over 20 minutes a week, a rise of about 45 percent.
Endline data for the control group show clear gender patterns in the activities carried out by boys and girls in both countries (online appendix, table S6). Boys were significantly less likely to engage in household chores and significantly more likely to engage in economic activities. Gender differences were bigger in Malawi than in Zambia. The study examined whether program impacts on child activities differed among boys and girls. In Malawi, some of the increases in engagement in household agricultural enterprises and household chores were significantly weaker among girls than among boys. In Zambia, where gender differences in child activities are smaller, statistically significant heterogeneity is not observed in program impacts by gender.
The study also explored robustness to using alternative outcome measures: productive activities carried out in the 12 months before the endline interview (as opposed to seven days) and, in Malawi, self-reported engagement in economic activities (as opposed to proxy-reported). These alternative outcome measures are not available for all productive activities and only for older children. The findings are consistent with an increase in children’s work in the household agricultural enterprise. (The results are available on request.)
In Malawi, 76 children were removed to equalize the attrition rate at 14.9 percent in the treatment and control groups. In Zambia, 57 children were removed to equalize the attrition rate at 18.1 percent.
This is implemented with the user-written ritest Stata command (Heß 2017).
The findings of the study here are also consistent with Ravallion and Wodon (2000), who conclude that school subsidies boosted school attendance significantly in Bangladesh without a corresponding reduction in child labor, a result challenging the common view that child labor displaces schooling.
The impacts on the probability of completing primary education and on the probability of completing lower secondary education were also examined. There is no evidence that these probabilities are significantly affected by the programs. Similarly, there are no statistically significant impacts on child logical reasoning in Malawi, as measured by a Raven’s test. (The results are available upon request.)
The investigation also involved the measurement of a fifth hazard: exposure to loud noise or vibration. The findings on this hazard are not displayed because only 2 percent of children in the data are exposed to loud noise. These five hazards were included in the study because Dayıoğlu (2012) shows that, after accounting for these five hazards, the measurement of additional hazards does not significantly change estimates of the incidence of hazardous work.
Point estimates for the same health outcomes in Zambia are also negative, but smaller and not statistically significant. (The results are available on request.)
Cases were also mentioned of youth facing bullying, violence, or intimidation during their chores or economic activities. Zietz, de Hoop, and Handa (2018) describe these cases in more detail.
