In this paper we present some new results for the dynamic agent model by Iossa and Rey (2014, "Building Reputation for Contract Renewal: Implications for Performance Dynamics and Contract Duration,'' Journal of the European Economic Association, 12, 549−574) while also correcting some errors...

"Implicit Contracts, incentive compatibility, and involuntary unemployment" (MacLeod and Malcomson, 1989) remains our most highly cited work. We briefly review the development of this paper and of our subsequent related work, and conclude with reflections on the future of relational contract...

The paper analyzes the choice of organizational structure as solution to the trade-off between controlling behavior based on authority rights and minimizing costs for implementing high efforts. The analysis includes the owner of a firm, a top manager and two division heads. If it is more...

The paper analyzes how the choice of organizational structure leads to the best compromise between controlling behavior based on authority rights and minimizing costs for implementing high efforts. Concentrated delegation and hierarchical delegation turn out to be never an optimal compromise. If...

We study dynamic moral hazard when the principal can only commit to spot contracts. Principal and agent are ex ante symmetrically uncertain about the difficulty of the job, and update their beliefs on observing output. Since the agent's effort is private, he has an additional incentive to shirk...

We study dynamic moral hazard with symmetric ex ante uncertainty about the difficulty of the job. The principal and agent update their beliefs about the difficulty as they observe output. Effort is private and the principal can only offer spot contracts. The agent has an additional incentive to...

We characterise optimal contracts in a dynamic principal-agent model of joint production in which project opportunities are heterogenous, utility from these projects is non-transferable and the agent has the option to quit the relationship at any time. In order to demand the production of...

Motivated by the ever-growing complexity of projects and the consistent trend of outsourcing of individual tasks or components, we study the contract-design problem faced by a firm (or organization) for executing a project consisting of multiple tasks, each of which is performed by an individual...

We study a relational contracting model with two agents where each agent faces multiple tasks: effort toward the agent's own project and helping effort toward another agent's project. We first propose the two-step approach, which is useful for characterizing the equilibrium of relational...

This paper studies organizational design as the allocation of decision rights, primarily focusing on its interplay with agents' career motives. I identify a new tradeoff between delegation and centralization, which arises solely from career concerns: When delegated, an agent takes inefficient...
