This paper specifies a general set of conditions under which the impacts of a policy can be identified using data generated under a different policy regime. We show that some of the policy impacts can be identified under relatively weak conditions on the data and structure of a model. Based on...

Does student aid increase college attendance or simply subsidize costs for infra-marginal students? Settling the question empirically is a challenge, because aid is correlated with many characteristics that influence educational investment decisions. A shift in financial aid policy that affects...

We present a variety of alternative estimates of the effect of training on the probability of employment for adult male participants in the 1976 Comprehensive Employment and Training Act (CETA) program. Our results suggest that CETA participation increased the probability of employment in the...

Without large increases in the number of health workers to treat HIV/AIDS (HAHW), most developing countries will be unable to achieve universal coverage with antiretroviral treatment (ART), leading to large numbers of potentially avoidable deaths among people living with HIV/AIDS. We use Markov...

Difference in differences methods have become very popular in applied work. This paper provides a new method for inference in these models when there are a small number of policy changes. This situation occurs in many implementations of these estimators. Identification of the key parameter...

Does the format of a financial aid program influence how it affects college decisions? This paper examines this question by focusing on state appropriations to public postsecondary institutions. While these funds subsidize tuition costs for in-state students, the in-kind format of the aid an...

In Israel, as in many other countries, a high school matriculation certificate is required by universities and some jobs. In spite of the certificate's value, Israeli society is marked by vast differences in matriculation rates by region and socioeconomic status. We attempted to increase the...

We use large-scale surveys of Chilean college applicants and college students to explore the way students form beliefs about earnings and cost outcomes at different institutions and majors and how these beliefs relate to degree choice and persistence. Linking our survey records to administrative...

This paper tests how migrants' willingness to remit changes when given the ability to direct remittances to educational purposes using different forms of commitment. Variants of a dictator game in a lab-in-the-field experiment with Filipino migrants in Rome are used to examine remitting behavior...

A central tax policy parameter that has recently received much attention, but about which there is substantial uncertainty, is the overall elasticity of taxable income. We provide new estimates of this elasticity which address identification problems with previous work, by exploiting a long...
