Economists have been theorizing that other-regarding preferences influence decision making. Yet, what are the corresponding psychological mechanisms that inform these preferences in laboratory games? Empathy and Theory of Mind (ToM) are dispositions considered to be essential in social...

Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

Abundant evidence suggests that high levels of contributions to public goods can be sustained through self-governed monitoring and sanctions. This experimental study investigates the effectiveness of decentralized sanctioning institutions where punishment opportunities are restricted to agents...
