This paper models individual choices of social groups and the formation of group identity, and examines the conditions with which the group identity reinforces the productivity of individuals. A social group is defined as a network that provides with a market for interactions to its members....

We develop a model of consulting (advising) where the role of the consultant is that she can reveal signals to her client which refine the client’s original private estimate of the profitability of a project. Importantly, only the client can observe or evaluate these signals...

In this paper, we study efficient dissolution of partnerships in a context of incomplete information. We generalize the results of Cramton, Gibbons and Klemperer (1987) to situations where the partnership takes on a common value that may depend upon all partners' types, so that each partner's...

We investigate the issue of implementation via individually rational ex-post budget-balanced Bayesian mechanisms. We demonstrate that all social choice rules that generate a nonnegative ex-ante surplus, including ex-post efficient ones, can generically be implemented via such mechanisms. The...

When a partnership comes to an end partners have to determine the terms of the dissolution. A well known way to do so is by enforcing a buy/sell option. Under its rules one partner has to offer a price for the partnership and the other agent can choose whether she wants to sell her share or buy...

In this paper we characterize the optimal allocation mechanism for $N$ objects, (permits), to $I$ potential buyers, (firms). Firms' payoffs depend on their costs, the costs of competitors and on the final allocation of the permits, allowing for externalities, substitutabilities and...

This paper is motivated by a practical income (or wealth) taxation problem: For a public good economy where the provision of public goods is to be financed by income taxes collected from individuals, what is the optimal feasible tax mechanism when a social planner is relatively uninformed of the...

In an abstract model of division problems, we study division rules that are not manipulable through a reallocation of individual characteristic vectors within a coalition (e.g. reallocation of claims in bankruptcy problems). A coalition can be formed if members of the coalition are connected on...

The Harris-Todaro model is reinterpreted under an evolutionary game approach, including the behavior of migrants under bounded rationality in a process of imitation or learning. A first feature is an improvement upon Harris-Todaro by replacing the sign-preserving function of the adjustment...

We report experimental results using a multi-task for simple two-player, two- stage extensive-form games. It is suggested that by creating the perception of a "level playing field" the participants are relieved of responsibility for others since competition on a level playing field is presumed...
