We compare the welfare effects of two different business strategies dealing with these problems....</p>

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...

Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and...

The privatization process in Eastern Europe is not irreversible. Future governments may want to (partially) expropriate successful private firms in order to subsidize unsuccessful ones. We use a simple median voter model to predict the policy of future governments. It is shown that there will be...

We show experimentally that fairness concerns may have a decisive impact on the actual and optimal choice of contracts in a moral hazard context. Bonus contracts that offer a voluntary and unenforceable bonus for satisfactory performance provide powerful incentives and are superior to explicit...

The paper offers a selective survey on the incomplete contracts approach to privatization. Furthermore, a simple model of privatization to an owner-manager is developed in which different allocations of ownership rights lead to different allocations of inside information about the firm which in...
