My new paper on real exchange rates and growth is now online. Here is the summary in abstractese:
I provide evidence that undervaluation (a high real exchange rate) stimulates economic growth. This is true particularly for developing countries, suggesting that tradable goods suffer disproportionately from the distortions that keep poor countries from converging. I present two categories of explanations as to why this may be so, focusing on (a) institutional/contractual weaknesses, and (b) market failures. A formal model elucidates the linkages between the level of the real exchange rate and the rate of economic growth.
The paper is still raw, so comments are appreciated.
