We present a tractable stochastic endogenous growth model that explains how social capital influences economic development. In our model, social capital increases citizens' awareness of government activity. Hence, it alleviates the electoral incentives to under- invest in education, whose...

This paper is the first to use a randomized trial in the US to analyze the short- and long-term educational and employment impacts of an afterschool program that offered disadvantaged high-school youth: mentoring, educational services, and financial rewards with the objective to improve...

This paper is the first to use a randomized trial in the US to analyze the short- and long-term impacts of an afterschool program that offered disadvantaged high-school youth: mentoring, educational services, and financial rewards to attend program activities, complete high-school and enroll in...

We postulate a two-region world, comprised of North (calibrated after the US) and South (calibrated after China). Our optimization results show the compatibility of the following three desiderata: (1) Global CO2 emissions follow a conservative path that leads to the stabilization of...

Since World War II, the United States government has made improved access to higher education a priority. This effort has substantially increased the number of people who complete college - generally thought to be a good thing. We show, however, that such policies can actually increase income...

This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e....

We propose a theoretical model to explain empirical regularities related to the curse of natural resources. This is an explicitly political model which emphasizes the behavior and incentives of politicians. We extend the standard voting model to give voters political control beyond the...

Whereas public student loans are often income contingent, private banks typically offer pure loans, or don't offer loans at all. In order to provide a rationale for these observations, we present a model with perfectly competitive banks and risk averse students who have private information on...

This expository paper describes the factors that contribute to failure of health insurance markets, and the regulatory mechanisms that have been and can be used to combat these failures. Standardized contracts and creditable coverage mandates are discussed, along with premium support, enrollment...

We implement a family of efficient proposals to share benefits generated in environments with externalities. These proposals extend the Shapley value to games with externalities and are parametrized through the method by which the externalities are averaged. We construct two slightly different...
