The U.S. dollar holds a dominant place in the invoicing of international trade, along two complementary dimensions. First, most U.S. exports and imports invoiced in dollars. Second, trade flows that do not involve the United States are also substantially invoiced in dollars, an aspect that has...

This paper provides an introduction to the recent literature on macroeconomic stabilization in closed and open economies. We present a stylized theoretical framework, and illustrate its main properties with the help of an intuitive graphical apparatus. Among the issues we discuss: optimal...

In this Paper we show that a currency area can be a self-validating optimal policy regime, even when monetary unification does not foster real economic integration and intra-industry trade. This is because profit-maximizing producers in a currency area adopt endogenous pricing strategies that...

It is well known that the extent of pass-through of exchange rate changes to consumer prices is much lower than to import prices. One explanation is local distribution costs. Here we consider an alternative, complementary explanation based on the optimal pricing strategies of firms. We consider...

Import competition from China is pervasive in the sense that for many good categories, the competitive environment that US firms face in these markets is strongly driven by the prices of Chinese imports, and so is their pricing decision. This paper quantifies the effect of the...

Large exporters are simultaneously large importers. In this paper, we show that this pattern is key to understanding low aggregate exchange rate pass-through as well as the variation in pass-through across exporters. First, we develop a theoretical framework that combines variable markups due to...
