Stable Trading Structures in Bilateral Oligopolies
This paper analyses the formation of trading groups in a bilateral market with strategic traders. A trading structure (a partition of the set of traders into trading groups) is strongly stable if no coalition of traders can deviate and increase the utility of some of its members while making no other member worse off. It is weakly stable if no coalition of traders can deviate and make all its members strictly better off. The only strongly stable trading structure is the grand coalition, where all agents trade on the same market. Other weakly stable trading structures exist and are characterized by a strong ordering property: trading groups can be ranked by size and cannot contain very different numbers of traders of the two types. In the particular example where traders have log-linear utility functions, the set of weakly stable trading structures is completely characterized.
