In two-person generosity games the proposer's agreement payoffis exogenously given whereas that of the responder is endogenouslydetermined by the proposer's choice of the pie size. Earlier resultsfor two-person generosity games show that participants seem to caremore for eciency than for equity....

Sanctions are widely used to promote compliance in principal-agent-relationships.While there is ample evidence confirming the predicted positive incentive effect of sanctions,it has also been shown that imposing sanctions may in fact reduce complianceby crowding-out intrinsic motivation. We add...

We analyze the effect of investments in corporate social responsibility(CSR) on workers’ motivation. In our experiment, a gift exchange game variant,CSR is captured by donating a certain share of profits to a charity. Weare testing for CSR effects by varying the possible share of profits given...

Actual behaviour is inuenced in important ways by moral emotions,for instance guilt or shame (see among others Tangney et al., 2007). Belief-dependant models of social preferences using the framework of psycho-logical games aim to consider such emotions to explain other-regardingbehaviour. Our...

Recent research has cast some doubt on the general validity of outcome-basedmodels of social preferences. We develop a model based on cognitive dissonance thatfocuses on the importance of self-image. An experiment (a dictator game variant)tests the model.First, we nd that subjects whose choices...

Empirical evidences show that investors tend to be biased toward investing indomestic (home bias) and local (local bias) stocks. Familiarity is considered to be one of thereasons. A similar concept was proposed by Goldstein and Gigerenzer (1999, 2002), known asthe recognition heuristic: “when...

In generosity games, one agreement payo is exogenously given,whereas the other is endogenously determined by the proposer's choice of the"pie" size. This has been shown to induce pie choices which are either efficiencyor equality seeking. In our experiment, before playing the generosity...

There is ample evidence that women do not react to competition as mendo and are less willing to enter a competition than men (e.g., Gneezy et al.(2003), Niederle and Vesterlund (2007)). In this paper, we use personalityvariables toto understand the underlying motives of women (and men) toenter a...

We examine in controlled experiments how individuals make choices when faced withmultiple options. The choice tasks mimic the selection of health insurance, prescriptiondrug, or retirement savings plans. However, in our experiment, the available options canbe objectively ranked. We ¯nd that the...

We experimentally show that current models of reciprocity are in-complete in a systematic way using a new variant of the ultimatumgame that provides second-movers with a marginal-cost-free punish-ment option. For a substantial proportion of the population, the de-gree of first-mover unkindness...
