The large, persistent fluctuations in international trade that can not be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings....

This paper examines micro data on U.S. firms' inventories during different macroeconomic episodes. Much of the analysis focuses on the 1981-82 recession, a recession that was apparently precipitated by tight monetary policy. We find important cross-sectional effects in this period: firms that...

In this paper we provide a framework to study the aggregate dynamic behavior of an economy where individual units follow (S,s) policies. We characterize structural and stochastic heterogeneities that ensure convergence of the economy's aggregate to that of its frictionless counterpart, determine...

This paper studies the dynamic properties of an imperfectly competitive economy with inventory holdings. In particular, we focus on the serial correlation in aggregate output and employment produced by the holding of inventories in one sector of the economy and the co-movement between sectors of...

This paper develops an open-economy macroeconomic model which can be used to interpret the observed fluctuations in output, inventories,prices,and exchange rates in the medium-sized economies of the world. The model is consistent with the major empirical regularities that have been discovered in...

Firms respond to fluctuations in demand by changing their inventories and their levels of production. The relative magnitudes of the inventory and production responses have important implications for the overall cyclical behavior of the economy. Government policies that affect the costs of...

Manufacturers' finished goods inventories move less than shipments over the business cycle. We argue that this requires marginal cost to be more procyclical than is conventionally measured. We construct, for six manufacturing industries, alternative measures of marginal cost that attribute...

In a recession, jobs are destroyed and inventories are liquidated. I concentrate on the intertemporal mechanisms that result in economy-wide job destruction and inventory runoffs. Forces that raise the real interest rate -- especially temporarily -- also cause destruction and runoffs. I consider...

We review and interpret recent work on inventories, emphasizing empirical and business cycle aspects. We begin by documenting two empirical regularities about inventories. The first is the well-known one that inventories move procyclically. The second is that inventory movements are quite...

Econometric aspects of recent research on inventory models are surveyed. The discussion emphasizes issues relevant to instrumental variables estimation of a first order condition of the Holt et al. (1960) linear quadratic inventory model, including choice of instruments, covariance matrix...
