The issue of the order dependence of iterative deletion procedures is well known in the game theory community, and conditions on the dominance concept underlying these procedures have meanwhile been detected which ensure order independence (see, e.g., the criteria of Gilboa et al. (1990) and Apt...

It is well-known that in finite strategic games true common belief (or common knowledge) of rationality implies that the players will choose only strategies that survive the iterated elimination of strictly dominated strategies. We establish a general theorem that deals with monotonic...

Within a laboratory experiment we investigate a principal-agent game in which agents may, first, self-select into a group task (GT) or an individual task (IT) and, second, choose work effort. In their choices of task and effort the agents have to consider pay contracts for both tasks as offered...

What is the motivational effect of imposing a minimum effort requirement? Agents may no longer exert voluntary effort but merely meet the requirement. Here, we examine how such hidden costs of control change when control is considered legitimate. We study a principalagent model where control...

From a game-theoretic point of view, fraudulent accounting to embellish the financial status of a firm and the use of drugs to enhance performance in sports are very similar. We study the replicator dynamics of such games. We allow for heterogeneous populations, such as highly talented versus...

We consider a principal-multiagent framework with adverse selection when contracting is possible ex ante. However, enforcement of contracts is imperfect, which results in inefficiencies. We study how group contracting may or may not mitigate those inefficiencies.

In this paper signals are observed by two receivers who have different preferences about the sender and therefore respond to information about himin different ways. This can result in a Catch-22 for the sender; if he sends a signal to induce a positive response from one receiver, this may induce...

We introduce the concept of a paramaterized collection of games with side payments and determine a bound on epsilon so that all sufficiently large games in such a collection have non-emplty epsilon-cores. A parametrized collection of games is described by (a) the number of approximate player...

We study pair-wise decentralized trade in dynamic markets with homogeneous, non-atomic, buyers and sellers that wish to exchange one unit. Pairs of traders are randomly matched and bargaining a price under rules that offer the freedom to quit the match at any time. Market equilbria, prices and...
