We study the monotonicity of sender's equilibrium strategy with respect to her type in signalling games. We use counterexamples to show that when the sender's payoff is non-separable, the Spence-Mirrlees condition cannot rule out equilibria in which the sender uses non-monotone strategies. These...

Our objective is to understand how a firm’s product development capability (PDC) affects the launch strategy for a durable product that is sequentially improved over time in a market where consumers have heterogeneous valuations for quality. We show that the launch strategy of firms is...

The paper studies Akerlof's market for lemons in a new way. We firstly construct mixed Perfect Bayesian Nash equilibria in which all qualities are sold on the market even if the seller's strategy set is reduced to prices. Then we turn to the best-reply matching (BRM) approach developed by...

When potential shareholders cannot observe the business conditions of the firms, the latter desiring to acquire capital by an IPO and operating under less favourable business conditions have a strong incentive to appear more successful.

This paper addresses the question of delegation in an organisation where there is an initial asymmetry of information between the principal and the agent. We assume that the principal cannot use revelation techniques à la Baron Myerson to elicit agent's superior information and in contrast, we...
