Experimental evidence on a range of interventions in developing countries is accumulating rapidly. Is it possible to extrapolate from an experimental evidence base to other locations of policy interest (from “reference” to “target” sites)? And which factors determine the accuracy of such...

This paper documents the evolving impact of childbearing on the work activity of mothers. Based on a compiled dataset of 441 censuses and surveys between 1787 and 2015, representing 103 countries and 48.4 million mothers, we document three main findings: (1) the effect of fertility on labor...

This paper examines how a change in the generosity of one social assistance program generates spillovers onto other social assistance programs. We exploit an age discontinuity in the stringency of the 1993 Dutch disability reforms to estimate the causal effect of exit from disability insurance...

Standard economic models of tax compliance have focused on enforcement-driven compliance. Notably, tax administrators also tend to place a great deal of emphasis on the importance of improving "tax morale" by encouraging voluntary compliance, creating a culture of compliance, and changing social...

If the demand for credit by the poor changes little when interest rates increase, lenders can raise fees to cost-covering levels without losing customers. This claim is at the core of sustainable microfinance strategies that aim to provide banking services to the poor while eschewing long-term...

This paper compares trends in wage inequality in the U.S. and Germany using an approach developed by MaCurdy and Mroz (1995) to separate age, time, and cohort effects. Between 1979 and 2004, wage inequality increased strongly in both the U.S. and Germany but there were various country specific...

Since the late 1970s, wage inequality has increased strongly both in the U.S. and Germany but the trends have been different. Wage inequality increased along the entire wage distribution during the 1980s in the U.S. and since the mid 1990s in Germany. There is evidence for wage polarization in...

While many studies have found that the EITC increases the employment rates of single mothers, no study to date has examined whether the jobs taken by single mothers as a result of the EITC incentives are dead-end jobs or jobs that have the potential for earnings growth. Using a panel of...

We construct and estimate an economic model of religious giving. We employ a dynamic consumer optimization model with mortality in which intra-temporal utility stems from both consumption and religious contributions. Individuals also decide how to allocate resources between religious...
