Thesis: My thesis explores three questions in the field of development economics. The first article, “Women At Work: Evidence From A Randomized Experiment In Djibouti” studies the determinants of the labor supply of women. Abstract: What keeps women in some developing countries from participating in the labor market? Is it limited job opportunities or limiting social norms? We examined the effects of these two factors on the labor supply decisions of women in urban Djibouti. Women were randomly assigned offers to be employed in a workfare program. The offers were exclusively targeted at women; the work could be performed by any other household member; and the earnings were paid out into a bank account established for the person who performed the work. We find a net increase in labor supply of over 50 percentage points: 96 percent of the women accepted the offers and 73 percent of women performed the work themselves. We observed none of the longer-term effects on labor supply by women that we would have observed if the increases in women’s employment had changed prevailing social norms on women working. Indeed, the women who received the temporary employment offer reverted back to non-participation in the labor market when the program ended. This suggests that, in urban Djibouti, what keeps women from participating in the labor market is not so much deterrent social norms but limited employment opportunities. The second article, “Turning A Shove Into A Nudge? A “Labeled Cash Transfer” For Education” looks at the determinants of households’ education investments. Abstract: Conditional Cash Transfers (CCTs) have been shown to increase human capital investments, but their standard features make them expensive. We use a large randomized experiment in Morocco to estimate an alternative government-run program, a “labeled cash transfer” (LCT): a small cash transfer made to fathers of school-aged children in poor rural communities, not conditional on school attendance but explicitly labeled as an education support program. We document large gains in school participation. Adding conditionality and targeting mothers made almost no difference in our context. The program increased parents’ belief that education was a worthwhile investment, a likely pathway for the results. The third article, “Estimating The Impact Of Microcredit On Those Who Take It Up: Evidence From A Randomized Experiment In Morocco”, studies how increased access to credit impact households in rural areas. Abstract: We report results from a randomized evaluation of a microcredit program introduced in rural areas of Morocco in 2006. Thirteen percent of the households in treatment villages took a loan, and none in control villages did. Among households identified as more likely to borrow, microcredit access led to a significant rise in investment in assets used for self-employment activities, and an increase in profit, but also to a reduction in income from casual labor. Overall there was no gain in income or consumption. We find suggestive evidence that these results are mainly driven by effects on borrowers, rather than by externalities.
