A cultural explanation of the foreign bias in international asset allocation

Abstract

This paper examines the foreign bias in international asset allocation. Following extant literature in behavioral finance, we argue that a society's culture and the cultural distance between two markets play an important role in explaining the foreign bias. In particular, we hypothesize that the degree of a nation's uncertainty avoidance affects the foreign bias (more uncertainty-avoiding countries allocate less to foreign markets), as does the degree of a country's individualism (in individualistic countries performance is more directly attributed to a person and less to teams, causing these individuals to be more aggressive in their foreign asset allocations). We further expect that the degree of cultural distance between two countries affects the amount of money allocated to that market. Based on extensive robustness analyses, we find support for our hypotheses on the role of culture in international asset allocation.
