How are the welfare costs from monopoly distributed across U.S. households? We answer this question for the U.S. credit card industry, which is highly concentrated, charges interest rates that are 3.4 to 8.8 percentage points above perfectly competitive pricing, and has repeatedly lost antitrust...

We present a general model of child labor that incorporates the various components presented in the literature as explanations for its existence. Our proposal is to mitigate the phenomenon by encouraging temporary emigration. It emerges that the remittances sent by the emigrating parents might...

Governments often aim to influence the amount and sectoral allocation of private investments through explicit or implicit subsidies. The rules used to select projects to benefit from subsidies may vary, depending on the policy objective. This paper develops a general framework to allocate...

This paper investigates the role of testing and age-composition in the Covid-19 epidemic. We augment a standard SIR epidemiological model with individual choices regarding how much time to spend working and consuming outside the house, both of which increase the risk of transmission. Individuals...

Production of commodities based on open-access renewable natural resources (NR) has usually been examined under "low" congestion (LC) – where MC AC and both increase with output. I identify two additional congestion categories, "high" (HC) and "super" (SC) congestion – where AC is...

We model a higher education system that admits students according to their admission signal (e.g., matriculation GPA, SAT), which is, in turn, affected by their cognitive ability and socioeconomic background. We show that subsidizing education loans increases neither human capital stock nor...

This paper is a practical guide for researchers and practitioners who want to understand spillover effects in program evaluation. The paper defines spillover effects and discusses why it is important to measure them. It explains how to design a field experiment to measure the average effects of...

This paper seeks to extend the domain of identity economics by exploring motivational foundations of in-group cooperation and out-group competition. On this basis, we explore the reflexive interaction between individual economic decisions and social identities in response to technological change...

This paper examines the reflexive interplay between individual decisions and social forces to analyze the evolution of cooperation in the presence of "multi-directedness," whereby people's preferences depend on their psychological motives. People have access to multiple, discrete motives....

Driven by an ever-growing number of studies that explore the effectiveness of institutional mechanisms meant to mitigate cooperation problems, recent years have seen an increasing interest in the endogenous implementation of these institutions. In this paper, we test within a unified framework...
