We provide cross-country and time series evidence on the extent of exchange rate pass-through into the import prices of 23 OECD countries. We find compelling evidence of partial pass-through in the short run, especially within manufacturing industries. Over the long run, producer-currency pricing is more prevalent for many types of imported goods. Countries with higher rates of exchange rate volatility have higher pass-through elasticities, although macroeconomic variables have played a minor role in the evolution of pass-through elasticities over time. Far more important for pass-through changes in these countries have been the dramatic shifts in the composition of country import bundles.

This paper argues that the documented discount on diversified firms is not per se evidence that diversification destroys value. Firms choose to diversify. We use three alternative econometric techniques to control for the endogeneity of the diversification decision, and find evidence supporting the selfselection of diversifying firms. We find a strong negative correlation between a firms choice to diversify and firm value. The diversification discount always drops, and sometimes turns into a premium. There also exists evidence of selfselection by refocusing firms. These results point to the importance of explicitly modeling the endogeneity of the diversification status in analyzing its effect on firm value.
