What are the effects on the labor market and aggregate income of frictions that restrict women's labor decisions that impede labor participation and composition being equal between men and women? To answer this question, I develop an occupational general equilibrium model with heterogeneous...

Controversies about aid effectiveness go back decades. Some experts charge that aid has enlarged government bureaucracies, perpetuated bad governments, enriched the elite in poor countries, or just been wasted. Others argue that although aid has sometimes failed, it has supported poverty...

Many existing classifications of developing countries are dominated by income per capita (such as the World Bank’s low, middle, and high income thresholds), thus neglecting the multidimensionality of the concept of ‘development’. Even those deemed to be the main ‘alternatives’ to the...

Recent years have seen rising discussion of ethical consumption as a means of stemming global warming, challenging unsavory business practices, and promoting other pro-social goals. This paper first lays out a conceptual framework for understanding the spread of ethical consumption, in which...

Although there has been little economic research on 'ethical consumption' in a general sense, work on its various aspects is growing. This paper reviews economic research on ethical consumption, examining both demand-and supply-side aspects. It is argued that the most promising way to see...

We estimate wage differentials across different sectors of the Mexican economy. The results suggest that the wage differential between the formal and informal sectors is significant and larger than the differential between industry and services. The findings suggest that significant differences...

Does the disclosure of information about corrupt activities induce a sustained reduction in corruption? We use longitudinal data on audits of municipal governments in Puerto Rico to answer this question. We find that corruption is lower in municipalities audited before an election. However,...

I study the impact of the COVID-19 pandemic on the formal employment of entrants from each post-Great Recession year. Using longitudinal Mexican social security records and an individual fixed-effects difference-in-differences design, I find that the pandemic caused more recent entrants from...

I review a contemporary branch of the informal sector literature that focus on understanding the way firm behavior is affected by the presence of informality and how such distortions have an impact on aggregate variables. The authors in this group all make use of dynamic general equilibrium...
