In this paper, we document a novel fact that disclosures of public information reshape social dynamics in China. Using the staggered roll-out of a quasi-natural experiment of air pollution information disclosure and a novel high-frequency data set of social and public events, we find...

Using a novel city-level high-frequency panel data set of social and public events in Chinese cities, we document that extreme high temperatures significantly reshape social dynamics. Extreme high temperatures lead to an increase in social cooperation, and the effects are more salient when...

This paper proves the existence, for a translation-invariant preorder on a divisible commutative group, of a complete preorder extending the preorder in question and satisfying translation invariance. We also prove that the extension may inherit a property of continuity. As an application, we...

Costly competitions between economic agents are modeled as contests. Researchers use laboratory experiments to study contests and test comparative static predictions of contest theory. Commonly, researchers find that participants’ efforts are significantly higher than predicted by the standard...

We prove the existence, for a translation-invariant preorder on a divisible commutative group, of a complete preorder extending the preorder in question and satisfying translation invariance (theorem 1). We also prove that the extension may inherit a property of continuity (theorem 2). This...

We show that the problem of evaluating infinite sequences (or streams) of utilities by a unique utility (or social welfare function) can be stated in terms of fuzzy subsets of the set of infinite utility sequences. For each stream, its evaluation can be viewed as its degree of membership to the...

This paper belongs to my research program on violence and terrorism started in 1993, as a consequence of the growing concern regarding the increase in Colombian violence, and especially for its escalation during the 1990’s. After 14 years of research, particularly after developing a model of...

This paper develops a theory of sequential lending in groups in micro-finance that centers on the notion of dynamic incentives, in particular the simple idea that default incentives should be relatively uniformly distributed across time. In a framework that allows project returns to accrue over...

Intergenerational transfers are both common and markedly unequal. This study conducts a large-scale experiment to explore how Americans and Chinese perceive the fairness of unequal wealth transfers. In the experiment, workers and their parents completed assignments. Workers' payoffs originated...
