We study a two periods entry game where the incumbent .rm, who has private information about his own production costs, makes a non observable long run investment choice, along with a pricing decision observed by the entrant. The investment choice affects both post-entry competition and first...

This paper analyzes the variety of optimal screening contracts in a relatively simple multidimensional framework a` la Armstrong and Rochet (1999), when only three types of agents are present. It is shown, among other things, that the well known principle in optimal contract theory of `no...

The Weak Weak Axiom (WWA) for the aggregate excess demand function ensures uniqueness of equilibrium in regular economies. Jerison (1999) shows that the WWA holds if the excess demand satisfies the hypothesis of Nondecreasing Dispersion of Excess Demand (NDED). This note offers a new hypothesis...

The paper shows that any sigma-transitive preference can be extended to a complete preference preserving sigma-transitivity. The result has potential applications to the theory of choice and specifically to revealed preference theory.

In a framework à la Martin (1993) we introduce a common component in the managers' private information in order to address three related questions: What is the impact of contracts that reward managers on the basis of realized profits on firms' productive and allocative efficiency relative to...

We present a dynamic OLG model of educational signaling, inequality and mobility with missing credit markets. Agents are characterized by two sources of unobserved heterogeneity: ability and parental income, consistent with empirical evidence on returns to schooling. Both quantity and quality of...

Using a difference-in-differences approach, we exploit a quasi-experiment occurred in a large public university located in Southern Italy, to study whether the introduction of a selective admission test affects two indicators of students’ performances: dropout rate and grade point average...
