Abstract

Does encouraging trader participation enhance market competitiveness? This paper shows that, when trader preferences are interdependent, trader market power does not necessarily decrease with greater participation, and traders need not become price takers in large markets. Thus, larger markets can be less liquid and associated with lower ex ante welfare. In the linear-normal model, the necessary and sufficient condition on the information structure is provided under which price impact is monotone in market size. A condition is given when the rational expectations equilibrium, which is typically not fully revealing within the considered class of preference interdependencies, is obtained in large markets.
