Many people are fired from their jobs for poor performance. However, it is difficult to distinguish whether they are fired because they are not well suited for their job (sorting explanation) or because the firms are trying to provide incentives for effort (incentive explanation). This paper...

We extend the $\Delta$-rationalizability (see Battigalli and Siniscalchi 2003) to infinite strategic form games with incomplete information. The most important feature of the $\Delta$-rationalizability is that there is no specified epistemic type space \`{a} la Harsanyi. However, we can impose a...

We consider a two-sided, finite-horizon search and matching model with heterogeneous types and complementarity between types. The quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market. When search is costless and all agents...

This paper presents a micro-model of knowledge creation and transfer in a small group of people. It is intended to contribute eventually to the development of microfoundations for aggregate models of knowledge externalities used in various literatures, such as those pertaining to endogenous...

Self regulation is a mechanism of quality vigilance that is frequently used in credence good industries. The providers in these markets generally form a Self Regulated Organization (SRO), composed by some members of the industry, whose main job is to convince consumers through an active...

We solve in closed form the optimal consumption / portfolio choice problem for the class of isoelastic utility functions under incomplete information about the mean return of the stock price. Our approach consists in converting the original investor's problem into an equivalent program where the...
