Golosov and Lucas recently argued that a menu-cost model, when made consistent with salient features of the microdata, predicts approximate monetary neutrality. I argue here that their model misses, in fact, two important features of the data. First, the distribution of the size of price changes in the data is very dispersed. Second, in the data many price changes are temporary. I study an extension of the simple menu-cost model to a multiproduct setting in which firms face economies of scope in adjusting posted and regular prices. The model, because of its ability to replicate this additional set of microeconomic facts, predicts real effects of monetary policy shocks that are much greater than those in Golosov and Lucas and nearly as large as those in the Calvo model. Although episodes of sales account for roughly 40% of all goods sold in retail stores, the model predicts that these episodes do not contribute much to the flexibility of the aggregate price level.

We examine the source of the large fall and rebound in US trade in the recent recession. While trade fell and rebounded more than expenditures or production of traded goods, we find that relative to the magnitude of the downturn, these trade fluctuations were in line with those in previous business cycle fluctuations. We argue that the high volatility of trade is attributed to more severe inventory management considerations of firms involved in international trade. We present empirical evidence for autos as well as at the aggregate level that the adjustment of inventory holdings help explain these fluctuations in trade.
