Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid - both internally and...

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

Previous findings on punishment have focused on environments in which the outcomes are known with certainty. In this paper, we conduct experiments to investigate how punishment affects cooperation in a two-person stochastic prisoner's dilemma environment where each person can decide whether or...

The minimax argument represents game theory in its most elegant form: simple but with stark predictions. Although some of these predictions have been met with reasonable success in the field, experimental data have generally not provided results close to the theoretical predictions. In a...

We present and experimentally test a mechanism that provides a simple, natural, low cost, and realistic solution to the problem of compliance with socially determined efficient actions, such as contributing to a public good. We note that small self-governing organizations often place enforcement...

This paper compares two methods to encourage socially optimal provision of a public good. We compare the efficacy of vigilante justice, as represented by peer-to-peer punishment, to delegated policing, as represented by the "hired gun" mechanism, to deter free riding and improve group welfare....

This paper studies the interactions between an individual's self esteem and his social environment in the workplace, at school, and in personal relationships. Because a person generally has only imperfect knowledge of his own abilities, people who derive benefits from his performance (parent,...

This paper explores the power of threats in the absence of binding commitment. The threatener cannot commit to carrying out the threat if the victim refuses payment, and cannot commit to not carrying out the threat if payment is made. If exercising the threat is costly to the threatener, then...

This paper investigates how Confucianism affects individual decision making in Taiwan and in China. We found that Chinese subjects in our experiments became less accepting of Confucian values, such that they became significantly more risk loving, less loss averse, and more impatient after being...

Saving when faced with the immediate option to spend is an unpleasant but not conceptually difficult task. One popular approach contradicts traditional economic theory by suggesting that people in debt should pay off their debts from smallest size to largest regardless of interest rate, to...
