Abstract

For a strategic market game (as introduced by Shapley and Shubik), following Dubey and Rogawski (1990), we provide a full explicit characterisation of the set of trading equilibria (in which all goods are traded at a positive price), for both the “buy and sell†and the “buy or sell†versions of this model under standard assumptions on the utility functions. We interpret and illustrate our equilibrium-characterising conditions; we also provide simple examples of trading equilibria, including those of non-interior strategy profiles (in which at least one trader is using the whole endowment in at least one good or money).
