The external influence of scholarly activity has to date been measured primarily in terms of publications and citations, metrics that also dominate the promotion and grant processes. Yet the array of scholarly activities visible to the outside world are far more extensive and recently developed...

Policies and explicit private incentives designed for self-regarding individuals sometimes are less effective or even counterproductive when they diminish altruism, ethical norms and other social preferences. Evidence from 51 experimental studies indicates that this crowding out effect is...

Empirical research suggests that - rather than improving incentives - exerting control can reduce workers' performance by eroding motivation. The present paper shows that intention-based reciprocity can cause such motivational crowding-out if individuals differ in their propensity for...

Awards are widespread in all countries and are prevalent both in the public sphere and in the private sector. This paper argues, and empirically supports, that awards serve public functions and economists should take them seriously. Using a unique cross-country data set, we suggest that awards...

Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from...

The widespread use of markets leads to unprecedented material well-being in many societies. We study whether market interaction, as a side effect, erodes moral values. An encompassing understanding of the virtues and vices of markets, including their possible impact on moral values, is necessary...

This paper studies the impact of a key feature of competitive markets on moral behavior: the possibility that a competitor will step in and conclude the deal if a conscientious market actor forgoes a profitable business opportunity for ethical reasons. We study experimentally whether people...

Economic and social interaction takes place between individuals with heterogeneous characteristics. We investigate experimentally the emergence and informal enforcement of different contribution norms to a public good in homogeneous and different heterogeneous groups. When punishment is not...

This paper investigates optimal contest design when the designer s payoff is increasing in competitive balance between contestants. A two-player contest with asymmetric effort costs (asymmetric abilities) is considered. Competitive balance is measured by the difference in winning probabilities...

This paper examines whether policymakers, economists at the Israeli Finance Ministry, act in their personal pension decisions in accordance with the rational behaviour assumptions underlying the pension policies they advance. We find that while economists' decisions regarding three other...
