Do financial innovations benefit or harm expected welfare? For innovations that provide greater access to banks, researchers have argued that lower transaction costs and better project assessments result in expected welfare gains. Others, however, have shown that with incomplete markets,...

What causes currency substitution (foreign money substituting for domestic money)? What significance has it had in recent banking crises? And what is the relationship between currency conversion and macroeconomic volatility in Latin America?Gomis-Porqueras, Serrano, and Somuano study how agents...

This paper assesses whether a causal relationship exists between recent increases in female labor force participation and the increased prevalence of obesity amongst women. The expansions of the Earned Income Tax Credit (EITC) in the 1980s and 1990s have been established by prior literature as...

The authors study optimal monetary policy in a model in which fiat money and private debt coexist as a means of payment. The credit system is endogenous and allows buyers to relax their cash constraints. However, it is costly for agents to publicly report their trades, which is necessary for the...

In this paper, we show that Ricardian equivalence does not hold in a representative agent framework if one considers goods whose current consumption affect future marginal utilities. We find that, when the intertemporal elasticity of substitution changes over time, the timing of lump sum...

This paper explores the incentives that students and instructors face when a new technology that grants access to online class materials is introduced. We examine the consequences for attendance and for the composition of live lectures. We also analyze how various sources of heterogeneity in...

This paper presents a theoretical framework that incorporates both preventive actions and treatment opportunities to study health outcomes. In particular, we allow for an agent's eating decision to alter the distribution of future health shocks. Once a shock is realized medical care can be used...
