This study examines the effect of real exchange rate changes on multinational firms and incorporates the effect of intra-industry competition on the relation between exchange rates and firm value. To test the relation more effectively, tests are conducted using a sample of automotive firms from the United States and Japan. Consistent with theoretical predictions, there is significant exposure to exchange rate shocks. Moreover, there is evidence of time-variation in exchange rate exposure, which is consistent with changes in the competitive environment within the industry. Finally, evidence is presented that is consistent with foreign sales being a major determinant of exposure and the effectiveness of operational hedging through foreign production.

Differences in culture, proxied by differences in religion and language, cannot be ignored when examining why investor protection differs across countries. We show that a country's principal religion predicts the cross-sectional variation in creditor rights better than a country's natural openness to international trade, its language, its income per capita, or the origin of its legal system. Catholic countries protect the rights of creditors less well than Protestant countries. A country's natural openness to international trade mitigates the influence of religion on creditor rights. Culture proxies are also helpful in understanding how investor rights are enforced across countries.
