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 RER shocks 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, and that the magnitude of the shock in the early 2000s was large enough to have played a role in the onset of secular stagnation, lending support to the Bernanke Hypothesis.
