Are quantitatively important real rigidities present in the data? The answer appears to depend on what data one looks at. Recent studies using price data underlying US CPI index provide evidence suggesting a limited role for real rigidities. Evidence from international prices, however, points...

Adjustment primarily occurred through existing importers and exporters changing their product mix. This implies that the macroeconomic impact of such rapid external adjustment does not come from the two channels most focused on in the literature: it does not result from the reallocation 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...
