Douglas Wind and Pelmutter advocated four approaches to international business: the ethnocentric approach, polycentric approach, regiocentric approach, and geocentric approach. The ethnocentric approach involves exporting the same products designed for the domestic market to foreign countries. The polycentric approach decentralizes decision-making to foreign executives. The regiocentric approach markets similar products designed for a region to neighboring countries. The geocentric approach operates subsidiaries globally as independent companies coordinated by the headquarters.
