Learning-by-exporting proponents argue that exporting increases productivity by exposing producers to new technologies or through product quality upgrading. This study is based on the observation that the technological superiority and severity of product quality requirements are not the same in...

Persistent interest rate differentials account for much of the currency carry trade profitability. "Commodity currencies" offer high interest rates on average, while countries that export finished goods tend to have low interest rates. We develop a general equilibrium model of international...

Persistent differences in interest rates across countries account for much of the profitability of currency carry trade strategies. "Commodity currencies'' tend to have high interest rates while low interest rate currencies belong to exporters of finished goods. This pattern arises in a...
