We study how informal buyer-supplier relationships in the German automotive industry affect procurement. Using unique data from a survey focusing on these, we show that more trust, the belief that the trading partner acts to maintain the mutual relationship, is associated with both higher...

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model where a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract's scope. In this model, the buyer balances the need to incentivize...

We reconsider the endogenous choice of delegation to a manager by two down-stream firms in both a Cournot and a Bertrand vertical market with network effects. An upstream monopolist charges a two-part tariff for a crucial input. By applying the Nash solution in a centralized bargaining, we show...

We investigate the role of mutual trust in long-term vertical relationships involving trades of complex goods. High complexity is associated with high contract incompleteness and hence the increased relevance of trust-based relational contracts. Contrary to expectations, we find that changes in...

Consider a principal-agent relationship in which more eort by the agent raises thelikelihood of success. Does rewarding success, i.e., paying a bonus, increase eort inthis case? I nd that bonuses have not only an incentive but also an income eect.Overall, bonuses paid for success may well reduce...

This paper offers a rationale for limiting the delegation of (real) authority, which neither relies on insurance arguments nor depends on ownership structure. We analyse a repeated hidden action model in which the actions of a risk neutral agent determine his future outside option. Consequently,...

Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South...

This paper presents a moral hazard model analyzing the agent's incentive to commit corporate crime. The principal can only observe profits which the agent can increase by committing crime or exerting effort. It is shown how different incentive contracts, i.e., thresholdlinear, capped bonus and...

While most market transactions are subject to strong incentives, transactions within firms are often not incentivized. We offer an explanation for this observation based on envy among agents in an otherwise standard moral hazard model with multiple agents. Envious agents suffer if other agents...

Political parties play a crucial gatekeeping role in elections, including controlling electoral resources, candidate recruitment, and electoral list compositions. In making these strategic choices, parties aim to encourage candidates to invest in the campaign, while also trying to secure...
