Given the intensive and ideologically charged debate over the use of private contractors for publicly funded services, it is somewhat surprising that many social scientists have preferred to explain government outsourcing by the pursuit of economic efficiency. Starting out from different...

We review the literature on public sector outsourcing to explore if the theoretical predictions from the incomplete contracts literature hold up to recent empirical evidence. Guided by theory, we arrange services according to the type and magnitude of their contractibility problems. The...

Why have economic reforms aimed at reducing the role of the state been successful in some cases but not others? Are reform failures the consequence of leviathan states that hinder private economic activity, or of weak states unable to implement policies effectively and provide a supportive...

In recent decades, information and communication technology (ICT) has been associated with far-reaching changes in the design of jobs. However, it still remains unclear whether these changes will lead to more centralization or more decentralization in firms. Previous literature on this debate...

Incentives often fail in inducing economic agents to engage in a desirable activity; implementability is restricted. What restricts implementability? When does re-organization help to overcome this restriction? This paper shows that any restriction of implementability is caused by an...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

In recent decades, many firms offered more discretion to their employees, often increasing the productivity of effort but also leaving more opportunities for shirking. These "high-performance work systems" are difficult to understand in terms of standard moral hazard models. We show...

Social interaction with colleagues is an important job attribute for many workers. To attract and retain workers, managers therefore need to think about how to create and preserve high-quality co-worker relationships. This paper develops a principal-multi-agent model where agents do not only...

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...

Subjective performance evaluations are commonly used to provide feedback and incentives to workers. However, such evaluations can generate significant disagreements and conflicts, the severity of which may be driven by many factors. In this paper we show that a workers' level of self-confidence...
