摘要

We study the effects of airport ownership (private vs. government) on welfare in the pres ence of airport complementarity, where each airport is located in a different country. Con sidering Cournot competition in the airline market, the unique Nash equilibrium is such that the two countries privatize their airports, even though both countries are better off, from a welfare perspective, with public (government-owned) airports. Considering a differ entiated Bertrand competition in the airline market, the same result prevails if the cross price elasticities are sufficiently high, otherwise the symmetric government-ownership of airports may also be a Nash equilibrium.
