This unique, extensive Handbook illustrates that multinational enterprises can contribute substantially to the competitive advantage of small countries. It advances the notion that small nations increasingly need to rely on both home-grown and foreign multinational enterprises to achieve domestic economic success in industries characterized by international competition.The expert contributors explore the roles of firms in a range of small, successful open economies driven by such multinational enterprises across the globe. They juxtapose country data sets against Professor Michael Porter's paradigm of single diamond components and show that these single diamond components reflect merely a set of initial conditions, which can be improved upon through both inward and outward direct investment. Concluding that multinational enterprises create resource linkages between the home and host environments in which they operate, this Handbook proves to be a fascinating read for academics, students and researchers with an interest in business and management, economics and international economics.
