Labor markets in turbulent times: some evidence from Mexico
Financial shocks increase the need to shift workers among employers, industries and occupations. These disruptions, in turn, can have adverse impacts on productivity.

The implications of capital-skill complementarity in economies with large informal sectors
In most developing nations, formal workers tend to be more experienced, more educated, and earn more than informal workers. These facts are often interpreted as evidence that low-skill workers face barriers to entry into the formal sector. Yet, there exists little direct evidence that such barriers are important. This paper describes a model where significant differences arise between formal and informal workers even though labor markets are perfectly competitive. In equilibrium, the informal sector emphasizes low-skill work because informal managers have access to less outside financing, and ...

Growing old together: firm survival and employee turnover
Labor market outcomes such as turnover and earnings are correlated with employer characteristics, even after controlling for observable differences in worker characteristics. We argue that this systematic relationship constitutes strong evidence in favor of models where workers choose how much to invest in future productivity. Because employer characteristics are correlated with firm survival, returns to these investments vary across firm types. We describe a dynamic general equilibrium model where workers employed in firms more likely to survive choose to devote more time to productivity ...

Inequality and growth: challenges to the old orthodoxy
Discussions of how best to alleviate poverty often center on the relative merits of policies that boost growth and those that promote redistribution. If greater inequality allows economies to expand faster, or if it?s an inevitable consequence of pro-growth measures, the two principles seem incompatible. Under such a scenario, societies seeking rapid growth rates have to forgo redistribution from rich to poor. Conversely, choosing a high degree of redistribution implies the decision to accept lower growth rates.

Constructing Pure-Exchange Economies with Many Equilibria
We develop a restart algorithm based on Scarf’s (1973) algorithm for computing approximate Brouwer fixed points. We use the algorithm to compute all of the equilibria of a general equilibrium pure-exchange model with four consumers, four goods, and 15 equilibria. The mathematical result that motivates the algorithm is a fixed-point index theorem that provides a sufficient condition for uniqueness of equilibrium and a necessary condition for multiplicity of equilibria. Examining the structure of the model with 15 equilibria provides us with a method for constructing higher dimensional models ...

Why do financial systems differ? History matters
We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different financial structures. Because setting up financial markets is costly in our model, economies that emphasize financial market lending are more likely to continue doing so in the future, all else equal.

Limited enforcement and the organization of production
This paper describes a dynamic, general equilibrium model designed to assess whether contractual imperfections in the form of limited enforcement can account for international differences in the organization of production. In the model, limited enforcement constrains some agents to operate establishments below their optimal scale. As a result, economies where contracts are enforced more efficiently tend to be richer and emphasize large scale production. Calibrated simulations of the model reveal that these effects can be large and account for a sizeable part of the observed differences in ...
