Economics of International Business sets out a new agenda for international business research. Mark Casson asserts that it is time to move the subject on from sterile debates about transaction cost economies and resource-based theories of the firm. Instead of focusing on the individual firm, the new agenda focuses on the global systems view of international business. A static view of the firm’s environment is replaced by a dynamic view which highlights the volatility of the international business environment. Coping with volatility requires entrepreneurial skills, flexibility and the need to synthesize information on a global basis. To co-ordinate the global system properly, entrepreneurs must co-operate through social networks of trust, as well as competing. Constructing a network of joint ventures, it is argued, is simply not enough.
