Abstract

We compare the welfare of different combinations of monetary and currency policies in an open-economy macroeconomic model that incorporates two important features of many small economies: a high level of vertical international trade and a prevalent use of a large trade partner's currency as the invoicing currency for both imports and exports. In this environment, a small economy prefers a fixed exchange rate regime over a flexible regime, while the larger economy prefers a flexible exchange rate regime. There are two main causes underlying our results. First, in the presence of sticky prices, relative prices adjust through changes in the exchange rate. Multiple stages of production and trade make it more difficult for one exchange rate to balance the whole economy by adjusting several relative prices throughout the vertical chain of production and trade. Namely, there is a trade-off between delivering an efficient relative price between home and foreign final goods and delivering an efficient relative price between home and foreign intermediate goods. Second, because the small economy uses the larger economy's currency in trade, it faces a high degree of exchange rate pass-through under a flexible regime and hence suffers from the lack of efficient relative prices in vertical trade. The larger economy, however, does not face this problem because its level of exchange rate pass-through is low.
