Chapter 6: Joint Ventures in the Transatlantic Airline Market

This study investigates, both theoretically and empirically, the effects of joint ventures on traffic. Although alliances are a pre-condition for joint ventures, both cooperation agreements are different in their nature. The reason is that alliances are revenue-sharing agreements, whereas joint ventures also involve a cost-sharing commitment. Our empirical analysis focuses on the transatlantic market, including non-stop routings (interhub markets) and one-stopover routings (interline markets). Our theoretical and empirical findings emphasize the relevance of economies of traffic density and reveal a positive effect of joint ventures on traffic, both in interhub and interline markets.
