This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

Labor market institutions, via their effect on the wage structure, affect the investmentdecisions of firms in labor markets with frictions. This observation helps explain rising wageinequality in the US, but a relatively stable wage structure in Europe in the 1980s. Thesedifferent trends are the...

Since changes in trade openness are typically confounded with other factors, it has been difficult to identify the labor market consequences of increased international trade. The advent of the United States Interstate Highway System provides a unique policy experiment, which I use to identify...

Over the last two decades, earnings in the United States increased at the top and at the bottom of the wage distribution but not in the middle - the intensely debated middle class squeeze. At the same time there was a substantial decline of employment in middle-skill production and clerical...

How do firms respond to technological advances that facilitate the automation of tasks? Which tasks will they automate, and what types of worker will be replaced as a result? We present a model that distinguishes between a task's engineering complexity and its training requirements. When two...

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: how are unemployment, job vacancies, and employment determined as equilibrium phenomena? What...

This paper explores the contribution of the minimum wage to the well documented rise in earnings inequality in Mexico between the late 1980 and the late 1990s. In contrast to the view that sees minimum wages as an ineffective redistributive tool in developing countries, we find that the...

The paper investigates the relationship between underground activities and financial deepening. The access to external finance requires entrepreneurs to disclose credible information through formal documentation. This requirement may be impossible to oblige to for many informal producers who...

Recessions and policy interventions in labour markets in developing countries are characterized not only by changes in the unemployment rate, but also by changes in the proportion of formal or protected jobs. This reallocation between formal and informal jobs is large and occurs mainly because...

A recent boom in commodities-for-manufactures trade between China and other developing countries has led to much concern about the losers from rising import competition in manufacturing, but little attention on the winners from growing Chinese demand for commodities. Using census data for...
