Notes: Risk aversion measures are standardised. Robust standard errors are reported in parentheses. Standard errors are clustered at sex worker level for sex act level analysis (Columns (3) and (4)). Each reported coefficient estimate is based on a separate OLS regression. ***p 0.01, **p 0.05, *p 0.1.SRRP stands for self-reported risk preferences. CRRA stands for constant relative risk aversion. Higher CRRA and lower SRRP mean greater risk aversion. Columns (3) and (4) refer to the two last paid sex intercourses.
Sex worker characteristics are age, last days expenditures, household size, marital status, altruism, preference for present, big five personality trait, religiosity, self-efficacy, self-control, happiness and depression index (cf. Table 7).
Enumerator characteristics include CRRA G&P, age, marital status, children, experience in surveying sex workers and years of experience in surveys.In column (2), the reported coefficients refer to the interaction term , see Appendix 2.
