Relative performance evaluation (RPE) is, at least on paper, enjoying widespread popularity in determining the level of executive compensation. Yet existing empirical evidence of RPE is decidedly mixed. Two principal explanations are held responsible for this discord. A constructional challenge arises from intricacies of identifying the correct peers. And on a simpler note, corporate...

Work and trade relationships are often governed by relational contracts, in which incentives for cooperative action today stem from the prospective future benefits of the relationship. In this paper, we study how reductions in clarity about the financial consequences of actions, induced by incomplete information about the costs of providing quality, affect relational contracts in...

This paper studies optimal dynamic tax policy under the threat of political reform. A policy will be reformed ex post if a large enough coalition of citizens supports reform; thus, sustainable policies are those that will continue to attract enough political support in the future. We find that optimal marginal capital taxes are either progressive or U-shaped, so that savings are...

BACKGROUND A small but increasing number of studies suggest that non-invasive brain stimulation by means of transcranial direct current stimulation (tDCS) can modulate arithmetic processes that are essential for higher-order mathematical skills and that are impaired in dyscalculic individuals. However, little is known about the neural mechanisms underlying such stimulation effects,...

Midbrain dopamine neurons encode reward prediction errors. In this issue of Neuron, Takahashi et al. (2016) show that the ventral striatum provides dopamine neurons with prediction information specific to the timing, but not the quantity, of reward, suggesting a surprisingly nuanced neural implementation of reward prediction errors.

Risk equalization mechanisms mitigate insurers’ incentives to practice risk selection. On the other hand, incentives to limit healthcare spending can be distorted by risk equalization, particularly when risk equalization payments depend on realized costs instead of expected costs. In addition, cost based risk equalization mechanisms may incentivize health insurers to distort the...

Die von den grössten amerikanischen Indexfonds gesammelten Mittel sind enorm, ihr Einfluss dementsprechend. Es entsteht die Befürchtung, dass der Wettbewerb in manchen Sektoren darunter leidet.

Extensive cleaning or checking of patients with obsessive-compulsive disorder (OCD) are often interpreted as strategies to avoid harm and as an expression of the widespread belief that OCD patients are more risk-averse. However, despite its clinical significance, the neural basis of risk attitude in OCD is unknown. Here, we investigated neural activity during risk processing using...
