We consider a society with informed individuals (adults) and naive individuals (children). Adults are altruistic towards their own children and possess information that allows to better predict the behavior of other adults. Children benefit from adopting behaviors that conform to the social norm...

People often form expectations about others using the lens of their own attitudes (the so-called consensus effect). We study the implications of this for trust and trustworthiness. Trustworthy individuals are more \optimistic" than opportunists and are accordingly less afraid to engage in...

We study Nature's trade-off when endowing people with the cognitive ability to distinguish between different time periods or different prizes. Our key premise is that cognitive ability is a scarce resource, to be deployed only where and when it really matters. We show that this simple insight...

We formally explore the idea that punishment of norm-breakers may be a vehicle for the older generation to teach youngsters about social norms. We show that this signaling role provides sufficient incentives to sustain costly punishing behavior. People punish norm-breakers to pass information...

We use a simple cost-benefit analysis to derive optimal similarity judgments - addressing the question: when should we expect a decision maker to distinguish between different time periods or different prizes? Our key premise is that cognitive resources are costly and are to be deployed only...

We measure satisfaction about experimental outcomes, personal and other participants' behaviour after a multiperiod "hybrid contribution" multiplayer prisoner's dilemma called the "vote with the wallet" game. Our work shows that participants who cooperated above median (which we defi ne as...

We run a modified dictator game experiment to investigate the determinants of donation choices to philanthropic organizations. We find experimentally that the adoption of a simple form of accountability such as the disclosure of information on the ranking of aggregate contributions received by...

We devise a ‘nudging' natural experiment to test the impact of a simple form of advertising on environmentally responsible products with/without the increase of the responsible product price. We find that the simple use of a small shelf-poster explaining the importance of buying a green...
