What is the impact of regulatory reforms that enhance credit market efficiency on children’s human capital? Using a parent-child panel dataset, we find that such reforms reduced children’s academic performance in low-income families. Consistent with the view that financial development...

We conduct a field experiment in Sri Lanka providing informal firms incentives to formalize. Information about the registration process and reimbursement of direct costs has no effect. Payments equivalent to one-half to one month (alternatively, 2 months) of the median firm's profits leads to...

In developing economies, mobile-linked services have the potential to significantly reduce transaction costs and provide a truly new conduit that could be used to facilitate the flow of savings into banks. We test this premise by introducing a product that permits Sri Lankan households to...

Longer life expectancy should encourage human capital accumulation, since a longer time horizon increases the value of investments that pay out over time. Previous work has been unable to determine the empirical importance of this life-expectancy effect due to the difficulty of isolating it from...

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...
