The paper reports the first experimental study on people's fairness views on extreme income inequalities arising from winner-take-all reward structures. We find that the majority of participants consider extreme income inequality generated in winner-take-all situations as fair, independent of...

A large-scale economic experiment, conducted on a representative sample of the US popula- tion, shows that cooperation creates special moral obligations. Participants in the experiment, acting as impartial spectators, transferred significantly more money to an unlucky worker when two individuals...

We report the results of a randomized controlled trial testing whether incentivizing physical exercise improves the academic performance of college students. As expected, the intervention increases physical activity. The main result is that it generates a strong and significant improvement in...

A core question in the contemporary debate on distributive justice is how the fair distribution of income is affected by differences in talent and effort. Important theories of distributive justice, such as strict egalitarianism, liberal egalitarianism and libertarianism, all give different...

Can lab experiments on student populations serve to identify the motivational forces present in society at large? We address this question by conducting, to our knowledge, the first study of social preferences that brings a nationally representative population into the lab, and we compare their...

This paper presents a new set of stylized facts about the global variation in universalism, leveraging hypothetical money allocation tasks deployed in representative samples of 64,000 people from 60 countries. Our data reveal large variation in universalism within and across countries, which...

This paper presents novel stylized facts about the global variation in universalism, leveraging nationally representative surveys across 60 countries (N=64,000). We find large variation in universalism within and across countries, which almost entirely reflects heterogeneity in people's moral...
