In this paper we develop a simple heterogeneous-agent model with incomplete markets to explain the prevalence of a large low-productivity, informal sector in developing countries. In our model, the provision of public infrastructure creates a productivity premium for formalization, which...

In this note we develop a simple heterogeneous-agent model with incomplete markets to explain the prevalence of a large, low-productivity, informal sector in developing countries. In our models, taxes levied on formal sector agents are used to finance the provision of a productive public...

Gains from trade come from a certain degree of specialization among trade partners. Specialization in the case of an agriculture-based developing country might be feared to imply a higher reliance than ever on low skill labor. Trade might thus be seen as a step away from the much awaited...

We show that coordination failures may be part of an explanation for the demographic differences between rich and poor countries and their differing attitudes towards the use of child labor. Our analysis is carried out within a two-period, general equilibrium model with endogenous fertility,...

In this paper, we show how coordination failures may explain the prevalence of child labor in developing countries. We do so within a simple game-theoretic setup. Child labor arises in our environment because of the lack of a coordination mechanism between parental decisions to invest in the...

This paper explores the political determinants of societies' tolerance for social exclusion on the basis of ethnicity, religion, or race. We develop a political-economic model of social exclusion with three main features. First, each individual living in this society must submit a political...

We use a household bargaining model to provide a rationale for gender discrimination in pay to disappear. In societies where women have a credible outside option to marriage and have the right to bargain with their future husband over the benefits of their union, the elimination of gender...

We explain the persistence of low performances in African agriculture by analyzing the determinants of farmers' decisions to modernize their farming practices. Owing to sociocultural factors specific to Sub-Saharan Africa, farmers' decisions on farming practices are strategic complements. We...
