Many models in the economics literature deal with strategic situations with privately informed agents. In those models the information structure is assumed to be exogenous and common knowledge. We consider whether such models, and the results they produce, are robust with respect the...

We analyse credit market equilibrium when banks screen loan applicants. When banks have a convex cost function of screening, a pure strategy equilibrium exists where banks optimally set interest rates at the same level as their competitors. This result complements Broecker's (1990) analysis,...

We analyze which normal form solution concepts capture the notion of forward induction, as defined by van Damme (JET, 1989) in the class of generic two player normal form games preceded by an outside option. We find that none of the known strategic stability concepts (including Mertens stable...

In this paper, we study how access pricing affects network competition when subscription demand is elastic and each network uses non-linear prices and can apply termination-based price discrimination. In the case of a fixed per minute termination charge, we find that a reduction of the...

European and the US mobile communication services markets have developed in rather different ways. There are striking differences in termination regulation and retail pricing models and one may wonder why this occurred and whether either of the markets outperforms the other in terms of...
