Firms compete for a contract and subcontract part of the work. If subcontracting takes place before the award of the contract, the revenue equivalence result breaks down, as subcontractors anticipate that their bids influence the probability of the firm winning the contract. Properties of the...

We analyze the classic moral hazard problem with the additional assumption that agents are inequity averse. The presence of inequity aversion alters the structure of optimal contracts. When the concern for equity becomes more important, there is convergence towards linear sharing rules. The...

We study the impact of internal decision-making structures on the stability of collusive agreements. To this end, we use a three-firm spatial competition model where two firms belong to the same holding company. The holding company can decide to set prices itself or to delegate this decision to...

We analyze the Moral Hazard problem, assuming that agents are inequity averse. Our results differ from conventional contract theory and are more in line with empirical findings than standard results. We find: First, inequity aversion alters the structure of optimal contracts. Second, there is a...

It is commonly observed that people refuse to obtain more detailed infor- mation about their health status, e. g. by not taking genetic tests, even if this information is costless and only disclosed to the individual. This observation is in contrast to the predictions of expected utility theory....

We consider a regulator who does not know how many firms should be granted a license to enter a market as he has limited information on their setup costs. We propose two auction formats which implement the efficient market structure. In a "jumping English auction" the price for a license...

By offering or choosing a contract the informed agent might reveal information to the principal which could be used for immediate renegotiation. This is discussed in an axiomatic approach. We show that if, given the revealed information, there exists a contract which is preferred by everyone,...

If bidders can acquire information during the auction the descending auction is no longer equivalent to a first-price-sealed-bid auction. Revenue equivalence does not hold. The incentive to acquire information can even be larger in a descending auction than in an ascending auction.
