Our study examines the announcement effects of 343 international greenfield investments by 289 U.S. firms for their impact on shareholder wealth. This paper develops five hypotheses based on the positive-multinational-network hypothesis. The evidence indicates that market reactions to announcements by firms entering developing countries are more favorable than those entering developed countries. In addition, the results show that the wealth effect for firms entering a host country for the first time is greater than for those that are already operating within the country. As for the long run, greenfield firms have shown improvement in their operating performance and stock performance.
