This essay provides an introduction to our recent work on robust mechanism design. The objective is to provide an overview of the research agenda and its results. We present the main results and illustrate many of them in terms of a common and canonical example, the single unit auction with...

The mechanism design literature assumes too much common knowledge of the environment among the players and planner. We relax this assumption by studying implementation on richer type spaces, with more higher order uncertainty. We study the "ex post equivalence" question: When is interim...

A number of studies, most notably Cr?mer and McLean (1985, 1988), have shown that in Harsanyi type spaces of a fixed finite size, it is generically possible to design mechanisms that extract all the surplus from players, and as a consequence, implement any outcome as if the players’ private...

Neeman (2004) and Heifetz and Neeman (2006) have shown that, in auctions with incomplete information about payoffs, full surplus extraction is only possible if agents’ beliefs about other agents are fully informative about their own payoff parameters. They argue that the set of...

We say that a social choice rule is implementable with (small) transfers if one can design a mechanism whose set of equilibrium outcomes coincides with that specified by the rule but the mechanism allows for (small) ex post transfers among the players. We then show in private-value environments...

Multi-product firms are modelled as locally interacting entities that gather information on the profitability of product combinations in an environment defined in terms of their currently supplied markets. They learn from their own past play. Local information gathering may slow down convergence...

Based on the axiomatic framework of Choquet decision theory, we develop a closed-form model of Bayesian learning with ambiguous beliefs about the mean of a normal distribution. In contrast to rational models of Bayesian learning the resulting Choquet Bayesian estimator results in a long-run bias...

We study compliance dynamics generated by a large set of behavioral rules describing social interaction in a population of agents facing an enforcement authority. When the authority adjusts the auditing probability every period, cycling in cheating-auditing occurs: Intensive monitoring induces...

En este trabajo se analiza la evolucion de una economia con dos tipos de firmas (innovadoras y no-innovadoras) y dos tipos de trabajadores (altamente calificados y poco calificados), en el que las decisiones de los trabajadores se encuentran definidas por conductas imitativas de comportamiento y...
