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.

In most countries, many of the largest corporations are controlled by large shareholders.We show that, under reasonable assumptions, this stylized fact implies that portfolio holdings of U.S. investors should exhibit a home bias in equilibrium.We construct an estimate of the world portfolio of shares available to investors who are not controlling shareholders.This available world portfolio differs sharply from the world market portfolio.In regressions explaining the portfolio weights of U.S. investors, the world portfolio of available shares has a positive significant coefficient but the world market portfolio has no additional explanatory power.This result holds when we control for country characteristics.
