This paper develops an analytically tractable general-equilibrium model of inventory dynamics based on a precautionary stockout-avoidance motive. The model’s predictions are broadly consistent with the U.S. business cycle and key features of inventory behavior. It is also shown that...

Conventional wisdom has it that inventory investment destabilizes the economy because it is procyclical to sales. Khan and Thomas (2007) show that the conventional wisdom is wrong in a general equilibrium (S,s) model with capital. We argue that their finding is not robust—the conventional...

I study the aggregate implications of the entry of Multinational Firms (MNFs) in a two country Dynamic Stochastic General Equilibrium model in which firms have heterogeneous productivity in the sense of Ghironi and Melitz (2005). Unlike the extant open economy macroeconomics literature, this...

There is substantial evidence that countries or regions with stronger trade linkages tend to have business cycles which are more synchronized. However, the standard international business cycle framework cannot replicate this finding. In this paper we study a multiple- country model of...

Presented at the 10th EABCN Workshop on Uncertainty over the Business Cycle, European Central Bank, Frankfurt.

The nature of the business cycle appears to have changed. Prior to the 1990s, recoveries from recessions were quick and steep; after the past three recessions, however, recoveries were weak and prolonged. We consider the effect of a number of countercyclical policies intended to shorten...

This paper constructs several models in which, unlike the standard neoclassical growth model, positive news about future technology generates an increase in current consumption, hours and investment. These models are said to exhibit procyclical news shocks. We find that all models that exhibit...
