AbstractWe investigate the impact of movements in the real exchange rate on economic growth based on …ve-year average data for a panel of over 150 countries in the post Bretton Woods period. Unlike previous literature, we use external instruments to deal with possible reverse causality from growth to the real exchange rate. Our country-speci…c instruments are (i) global capital ‡ows interacted with individual countries' …nancial openness and (ii) the growth rate of o¢ cial reserves. We …nd that a real appreciation (depreciation) reduces (raises) signi…cantly annual real GDP growth, more than in previous estimates in the literature. However, our results con…rm this e¤ect only for developing countries and for pegs.
Non-technical summaryThis paper takes another look at the effect of the real exchange rate on economic growth per capita from a medium term perspective, which is a question still unsettled in the literature following previous work by Rodrik (2008) and others. Its main contribution to the literature is in the identification strategy based on instrumental variables (IV). We aim at identifying exogenous movements in the real exchange rate, notably movements that are not driven by country-specific growth shocks, such as productivity shocks. We estimate the effect of real exchange rate movements on growth on a large panel of close to 150 countries over a sample of five-year periods from 1970 to 2010.The paper uncovers three main results:• Our identification strategy finds a strong and statistically significant positive (negative) effect of real depreciation (appreciation) on real per capita growth over five-year average periods. The effect is visible in developing countries and pegs, and is not significant or wrongly signed in advanced countries and floats.• The effects appear to be approximately symmetric between appreciations and depreciations, although large depreciations appear to have a stronger impact than large appreciations on average.• The effects that we estimate through the IV approach are much larger than previous comparable results in the literature.Our overall conclusion is that the real exchange rate does matter for growth in developing economies, but substantially less so in advanced ones, which confirms and strengthens the conclusions of Rodrik (2008).It should also be pointed out that our results suggest that using the exchange rate as a policy lever could be beneficial only in the early stages of economic development, while it becomes irrelevant in the long term...
