We study the response of factor allocation and the skill premium to trade liberalizations in a model that combines exogenous determinants of comparative advantage--that result from sectoral productivity and factor endowment differences across countries--with endogenous determinants of...

How do changes in the economic environment such as reductions in international trade costs or reductions in firms innovation costs impact aggregate productivity? More generally, how do changes in economic policies that affect market size, market structure, and the costs and benefits to firms of...

and that the derivative at the balanced growth equilibrium can be computed analytically from the primitives of the model.

We build a business cycle model where employers' screening of heterogeneous workers plays a central role in determining both the flows into and out of unemployment. The model can address how differences between the US and European labor market flows affect business cycle dynamics. It provides a...

This paper presents and estimates a sticky-price model with heterogeneous households and financial frictions. Frictions in state-contingent asset markets lead to imperfect risk-sharing among households with idiosyncratic labor incomes. I study the impacts of the introduced …financial frictions...

We develop a dynamic politico-economic model of public investment where decisions can be made at several levels of government: federal, state, or county. The model predicts that in the absence of internal mobility, the higher level of government would fund all investments that present positive...

We explore how developmental and regulatory impediments to resource reallocation limit the ability of developing countries to adopt technologies: an efficient economy quickly innovates; but when the economy is unable to fully use resources liberated by closing firms, or when policy distortions...

the incentive to adjust the workforce. I relax this assumption and introduce wage bargaining with multiple workers. A reduced-form empirical decomposition suggests that transitory shocks to sales have a strong effect on wages, but that permanent shocks have a very small effect on wages. I...

Many studies using business-level microdata have documented large size average differences across plant ages. New businesses tend to be much smaller than their established industry competitors. This size gap also closes slowly, taking well over a decade on average. We show that even for...
