We study the macroeconomic consequences of tariffs. We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. We find that tariff increases lead, in the medium term, to economically and statistically significant declines...

This paper reviews the large and growing literature which tests PPP and other models of the long-run real exchange rate. We distinguish three different stages of PPP testing and focus on what has been learned from each. The most important overall lesson has been that the real exchange rate...

We document a new international stylized fact describing the relationship between real exchange rates and external asset holdings. Economists have long argued that the real exchange rate is associated with the net international investment position, appreciating as external wealth increases. This...

This paper studies how the monetary policy regime affects the relative importance of nominal exchange rates and inflation rates in shaping the response of real exchange rates to shocks. We document two facts about countries with floating exchange rates where monetary policy controls inflation...

Economic historians' Divergence debates since 2000 have asked a different question from that asked by Angus Maddison. The issue has become "when did countries' contemporaneous purchasing powers diverge?", not "when did countries' productivity grow at different rates?" The two questions have...

Historical data for over hundred years and 14 countries is used to estimate the long-run effect of productivity on the real exchange rate. We find large variations in the productivity effect across four distinct monetary regimes in the sample period. Although the traditional Balassa-Samuelson...

Long half-lives of real exchange rates are often used as evidence against monetary sticky price models. In this study we show how exchange rate regimes alter the long-run dynamics and half-life of the real exchange rate, and we recast the classic defense of such models by Mussa (1986) from an...
