Relative Prices and Hysteresis: Evidence from US Manufacturing

A central tenet of economics is that prices matter. A corollary is that in a world with sunk costs, historical prices can affect current economic outcomes. There exists a large theoretical literature on exchange rate hysteresis, but recent empirical treatments are scarce. To fill the gap, I employ new measures of real exchange rates (RERs) to study the impact of large, temporary movements in relative prices on the US manufacturing sector. To identify a causal impact of RER movements on manufacturing, I test whether sectors more exposed to international trade respond differently when relative prices appreciate. I also compare the US experience to Canada's in the mid-2000s, when high oil prices and a falling US dollar led to an equally sharp appreciation of the Canadian dollar. I find that temporary RER shocks have a surprisingly persistent impact on employment, output, and productivity in relatively more open manufacturing sectors.
