Table 7. PSM model using one nearest-neighbor matching that compares adopting and not-adopting fields in terms of yields, gross revenues, and net revenues per hectare.
| Variable | Coefficient | (AI Robust s.e.) | P value | |
|---|---|---|---|---|
| Yield | Adoption (1 vs 0) | -6.915 | (252.557) | 0.978 |
| Gross revenue | Adoption (1 vs 0) | -1880.058 | (1141.726) | 0.100 |
| Net revenue 1 | Adoption (1 vs 0) | -1887.052 | (1366.867) | 0.167 |
| Net revenue 2 | Adoption (1 vs 0) | -2106.106 | (1377.132) | 0.126 |
| Net revenue 3 | Adoption (1 vs 0) | -2089.473 | (1443.235) | 0.148 |
Total number of observations for yield analysis is 809 fields in the 2017/2018 Dong Xuan season, whereas for revenue analysis the number of observations is only 766 due to an unobserved selling price of rice in the case of all rice consumed by households.
