[As domestic sources of outside finance are limited in many countries around the world, it is important to understand factors that influence whether foreign investors provide capital to a country's firms. We study 4,409 firms from twenty-nine countries to assess whether and why concerns about corporate governance result in fewer foreign holdings. We find that foreigners invest less in firms that reside in countries with poor outsider protection and disclosure and have ownership structures that are conducive to governance problems. This effect is particularly pronounced when earnings are opaque, indicating that information asymmetry and monitoring costs faced by foreign investors likely drive the results.]

We merge portfolio theories of home bias with corporate finance theories of insider ownership to create the optimal corporate ownership theory of the home bias. The theory has two components: (1) foreign portfolio investors exhibit a large home bias against countries with poor governance because their investment is limited by high optimal ownership by insiders (the “direct effect” of poor governance) and domestic monitoring shareholders (the “indirect effect”) in response to the governance and (2) foreign direct investors from “good governance” countries have a comparative advantage as insider monitors in “poor governance” countries, so that the relative importance of foreign direct investment is negatively related to the quality of governance. Using both country‐level data on U.S. investors' foreign investment allocations and Korean firm‐level data, we find empirical evidence supporting our optimal corporate ownership theory of the home bias.
