Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. An efficient risk classification system generates premiums that fully reflect the...

This paper analyzes the trade of an indivisible good within a two-stage mechanism, where a seller first negotiates with one potential buyer about the price of the good. If the negotiation fails to produce a sale, a second-price sealed-bid auction with an additional buyer is conducted. The...

We study the policy choice of an incumbent politician who is concerned with the public's perception of his capability. The politician decides whether to maintain the status quo or to conduct a risky reform. The success of the reform critically depends on the ability of the politician in oce,...

This article is an experimental investigation on decision making in online auction markets. We focus on a widely used format, the Buy-It-Now auction on eBay, where sellers post prices at which buyers can purchase a good prior to an auction. Even though, buyer behavior is well studied in...

A contingent contract in a transferable utility game under uncertainty specifies an outcome for each possible state. It is assumed that coalitions evaluate these contracts by considering the minimal possible excesses. A main question of the paper concerns the existence and characterization of...

Did the recent transition to liberal democracy in Eastern Europe consitute revolutions? Here, game theory is used to structure an explanation of institutional change proposed by Harold Innis (1950).

This paper develops an extension of the recursive core to the setting of overlapping coalitions. We show that the cooperative game theoretical traditional way of separating a deviant coalition from the game played by the ones left behind is no more satisfactory. We therefore introduce a new...

The rationalizability of a choice function by means of a transitive relation has been analyzed thoroughly in the literature. However, not much seems to be known when transitivity is weakened to quasi-transitivity or acyclicity. We describe the logical relationship between the different notions...
