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...

We introduce intention-based social preferences into a mechanism design framework with independent private values and quasilinear payoffs. For the case where the designer has no information about the intensity of social preferences, we provide conditions under which mechanisms which have been...

The goal of this paper is to draw some lessons for economic theory from research in psychology, social psychology and, more briefly, in biology, which purports to explain the formation of social preferences. We elicit the basic mechanisms whereby a variety of social preferences are determined in...

Experimental evidence from dictator games and simple choice situations indicates concerns for fairness and social welfare in human decision making. At the same time, models of inequality averse agents fail to explain the experimental data of individuals who reduce their payoff below a fair split...

It is standard in experimental economics to use decontextualized designs where payoff structures are presented using neutral language. Here we show that cooperation in such a neutrally framed Prisoner’s Dilemma is equivalent to a PD framed as contributing to a cooperative endeavour....

We introduce intention-based social preferences into a Bayesian mechanism design framework. We first show that, under common knowledge of social preferences, any tension between material efficiency, incentive compatibility, and voluntary participation can be resolved. Hence, famous impossibility...

Altruism, giving and pro-social conduct, and reciprocity, are the basis of the existence and performance of societies, through their various occurrences: in families; among the diverse motives of the political and public sector; as the general respect and moral conduct which permit life in...

To statistically infer the motives underlying pro-social behavior, econometric models of choice are required. Such inference is comparable across studies if the choice model yields estimates that are precise in-sample and robust out-of-sample. Analyzing two extensive dictator game data sets, I...

We re-examine the seminal persuasion model of Dye (1985), focusing on the contracting power of current shareholders. Current shareholders determine the disclosure policy of a manager, who may be informed about the firm's value. Current shareholders desire higher future stock prices and dislike...
