Exchange Rate Uncertainty and the Law of One Price

This paper develops a framework for analyzing the impact of exchange rate uncertainty on the Law of One Price. Using the prices of very disaggregated, homogeneous products in a very open economy, Chile, where no institutions exist for hedging exchange risk, it then tests the model in a bivariate GARCH in mean context. Little evidence is found that short-run exchange rate uncertainty consititutes a barrier to goods arbitrage.
