The Adjustment of Global External Imbalances: Does Partial Exchange Rate Pass-Through to Trade Prices Matter?
Christopher Gust and Nathan Sheets
Abstract:
This paper assesses whether partial exchange rate pass-through to trade prices has important implications for the prospective adjustment of global external imbalances. To address this question, we develop an open-economy DGE model in which firms set their prices with an eye toward maintaining their competitiveness against other producers; this feature of the model generates a variable desired markup and, hence, pass-through that is less than complete. With trade price elasticities of unity or greater, we find that for a given move in the exchange rate the nominal trade balance adjusts more when pass-through is high. However, an ofsetting consideration is that the exchange rate tends to be more sensitive to shocks in a low pass-through environment. We show that the relative importance of these considerations depends on the structural features of the economy, including the magnitude of the trade price elasticities and the sensitivity of private spending to shocks.
