We show that concerns for fairness may have dramatic consequences for the optimal provision of incentives in a moral hazard context. Incentive contracts that are optimal when there are only selfish actors become inferior when some agents are concerned with fairness. Conversely, contracts that...

This Paper reports on a two-task principal-agent experiment in which only one task is contractible. The principal can either offer a piece-rate contract or a (voluntary) bonus to the agent. Bonus contracts strongly outperform piece rate contracts. Many principals reward high efforts on both...

Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

We provide experimental evidence that contractual incompleteness, ie, the absence of third party enforcement of workers’ effort or the quality of the good traded causes a fundamental change in the nature of market interactions. If contracts are complete the vast majority of trades are...

In this study we find that the set of policies that favor liberalization in credit markets (regulatory quality) are negatively correlated with countries’ resilience to the recent recession as measured by output growth in 2008 and 2009.

Starting in Spain in the twelfth century, parliaments gradually spread over the Latin West. The paper quantifies the activity of medieval and early-modern parliaments, which also makes it possible to analyse the influence of this institutional innovation. In the early-modern period parliaments...

China’s economic reforms have resulted in spectacular growth and poverty reduction. However, China’s institutions look ill-suited to achieve such a result, and they indeed suffer from serious shortcomings. To solve "China puzzle" this paper analyses China’s institution - a regionally...

We investigate the impact of slavery on the current performances of the US economy. Over a cross section of counties, we find that the legacy of slavery does not affect current income per capita, but does affect current income inequality. In other words, those counties that displayed a higher...

The inheritance of contemporary financial economics invites us to consider financial stability as integral to a liberal market setting. The crisis however demonstrated that financial markets may prove highly dysfunctional in the absence of adequate mechanisms of regulation and governance. This...

We use variation in oil output among Brazilian municipalities to investigate the effects of resource windfalls. We find muted effects of oil through market channels: offshore oil has no effect on municipal non-oil GDP or its composition, while onshore oil has only modest effects on non-oil GDP...
