Secondary schools in the developed world differ in the degree of differentiation and in the first age of selection of pupils into different tracks. In this paper, we account for the heterogeneity of tracking time with a simple stochastic model which conjugates the returns from specialization...

This paper constructs a dynamic model of health insurance to evaluate the short- and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions...

Estimates using admissions lotteries suggest that urban charter schools boost student achievement, while charter schools in other settings do not. Using the largest available sample of lotteried applicants to charter schools, we explore student-level and school-level explanations for this...

We present a theory explaining the impact of ability tracking on academic performance based on grading policies. Our model distinguishes between initial ability, which is mainly determined by parental background, and eagerness to extend knowledge. We show that achievements of low ability...

We argue that once we take into account the students’ rational enrollment decisions, mismatch in the sense that the intended beneficiaries of affirmative action admission policies are made worse off ex ante can only occur if selective universities possess private information. Ex ante mismatch...

Pressing questions about the merits of market accountability in K-12 education have spawned a large scholarly literature. Unfortunately, much of that literature is of limited relevance, and some of it is misleading. The studies most widely cited in the United States used intense scrutiny of a...

Research on centralized school assignment mechanisms often focuses on whether parents who participate in specific mechanisms are likely to truthfully report their preferences or engage in various costly strategic behaviors. However, a growing literature suggests that parents may not know enough...

This paper constructs a dynamic model of health insurance to evaluate the short- and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions...

In our efforts to better understand how policies geared towards poverty reduction may impact teen childbirth, we analyzed the impact of the 10-20-30 provision of the American Recovery and Reinvestment Act of 2009 (ARRA, P.L. 111-5) on teen childbirth. The 10-20-30 provision allocated at least...

This paper quantifies the unequal welfare effects of tax competition. I derive the optimal tax and transfer schedules in a free mobility union composed of countries that can either compete or set a uniform federal tax rate. In the absence of fiscal coordination, governments internalize that any...
