The chapter introduces the concept of MultiMexicans, Mexican multinational companies, as a way to study how firms from emerging markets expand internationally. It compares traditional models of multinational firms from advanced economies with new models specific to emerging market firms. By analyzing MultiMexicans, we can better understand how the home country influences international expansion and the challenges these firms face when going global. The chapter concludes by summarizing the book's contents and lessons learned from studying MultiMexicans in various industries.
