We experimentally study behavior in a simple voting game where players have private information about their preferences. With random matching, subjects overwhelmingly follow the dominant strategy to exaggerate their preferences, which leads to inefficiency. We analyze an exogenous linking...

I suppose that people react with anger when others show themselves not to be minimally altruistic. With heterogeneous agents, this can account for the experimental results of ultimatum and dictator games. Moreover, it can account for the surprisingly large fraction of individuals who offer an...

We test whether promises per se are effective in enhancing cooperative behavior in a form of a trust game. In Charness & Dufwenberg (2006) we found considerable effectiveness for free-form personalized pre-play statements-of-intent ("promises"), in support of a theory of belief-dependent guilt...

We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others' expectations in order to avoid guilt, as can be modeled using psychological game...

Reciprocity is one of the main basic social relations that constitute societies. It consists of being favourable to others because others are favourable to you (and not from an exchange in the strict sense). It rests on three possible rationales: (1) balance (comparison, matching), often related...

This chapter reviews the theory of the voluntary public and private redistribution of wealth elaborated by economic analysis in the last forty years or so. The central object of the theory is altruistic gift-giving, construed as benevolent voluntary redistribution of income or wealth. The theory...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...

What is the role of intuitive versus deliberative cognitive processing in human cooperation? The Social Heuristics Hypothesis (SHH) stipulates that (i) intuition favors behaviors that are typically advantageous (i.e. long-run payoff-maximizing), and that for most people cooperation is typically...
