Credit Frictions in the Great Recession
Although a credit tightening is commonly recognized as a key determinant of the Great Recession, to date, it is unclear whether a worsening of credit conditions faced by households or by firms was most responsible for the downturn. Some studies have suggested that the household-side credit channel is quantitatively the most important one. Many others contend that the firm-side channel played a crucial role. We propose a model in which both channels are present and explicitly formalized. Our analysis indicates that the household-side credit channel is quantitatively more relevant than the ...

The Macroeconomic Dynamics of Labor Market Policies
We develop a dynamic macroeconomic framework with worker heterogeneity, putty-clay adjustment frictions, and firm monopsony power to study the distributional impact of labor market policies over time. Our framework reconciles the well-known tension between low short-run and high long-run elasticities of substitution across inputs of production, especially among workers with different skills within a same education group. We use this framework to evaluate the effects of redistributive policies such as the minimum wage and the Earned Income Tax Credit. We argue that since these policies ...

Asset Prices and Unemployment Fluctuations
Recent critiques have demonstrated that existing attempts to account for the unemployment volatility puzzle of search models are inconsistent with the procylicality of the opportunity cost of employment, the cyclicality of wages, and the volatility of risk-free rates. We propose a model that is immune to these critiques and solves this puzzle by allowing for preferences that generate time-varying risk over the cycle, and so account for observed asset pricing fluctuations, and for human capital accumulation on the job, consistent with existing estimates of returns to labor market experience. ...

The Distributional Impact of the Minimum Wage in the Short and Long Run
We develop a framework with rich worker heterogeneity, firm monopsony power, and putty-clay technology to study the distributional impact of the minimum wage in the short and long run. Our production technology is disciplined to be consistent with the small estimated employment effects of the minimum wage in the short run and the large estimated elasticities of substitution across inputs in the long run. We find that in the short run, a large increase in the minimum wage has a small effect on employment and therefore increases the labor income of the workers who were earning less than the new ...

Fiscal Unions Redux
Before the advent of sophisticated international financial markets, a widely accepted belief was that within a monetary union, a union-wide authority orchestrating fiscal transfers between countries is necessary to provide adequate insurance against country-specific economic fluctuations. A natural question is then: Do sophisticated international financial markets obviate the need for such an active union-wide authority? We argue that they do. Specifically, we show that in a benchmark economy with no international financial markets, an activist union-wide authority is necessary to achieve ...

Evolution of Modern Business Cycle Models: Accounting for the Great Recession
Modern business cycle theory focuses on the study of dynamic stochastic general equilibrium models that generate aggregate fluctuations similar to those experienced by actual economies. We discuss how this theory has evolved from its roots in the early real business cycle models of the late 1970s through the turmoil of the Great Recession four decades later. We document the strikingly different pattern of comovements of macro aggregates during the Great Recession compared to other postwar recessions, especially the 1982 recession. We then show how two versions of the latest generation of real ...

Careers in firms: estimating a model of learning, job assignment, and human capital aquisition
This paper develops and structurally estimates an equilibrium model of the labor market that integrates learning, job assignment, and human capital acquisition to account for the main patterns of job and wage mobility characteristic of careers in firms. A key innovation is the modeling of firms? incentives to experiment that arise from the ability of firms, through job assignment, to affect the rate at which they acquire information about workers. The resulting trade-off between output and information implies that a firm?s retention and job assignment policy solves an experimentation problem: ...

Learning-by-employing: the value of commitment under uncertainty
We analyze commitment to employment in an environment in which an infinitely lived firm faces a sequence of finitely lived workers who differ in their ability to produce output. The ability of a worker is initially unknown to both the worker and the firm, and a worker's effort affects the information on ability that is conveyed by performance. We characterize equilibria and show that they display commitment to employment only when effort has a persistent but delayed impact on output. In this case, by providing insurance against early termination, commitment encourages workers to exert effort, ...
