A country?s social welfare depends on firms? profits and consumers? surplus. Given unions of countries, a country?s aim is to maximize its own social welfare when it decides to enter or exit a union. For examining unions, we use the notion of a cover as elaborated in Koray (2007).We utilize the findings of İlkiliç(2010) about the Cournot equilibrium in our setting to examine core stability and efficiency of covers of countries.We adapt different rights? structures based on; free exit, free entry, approved exit and approved entry introduced by Sertel (1992) to the context of covers, along with introducing some stronger structures and study how stability of covers varies when linkage costs are imposed upon countries.
