Similar to Levati and Neugebauer (2001), a clock is used by which participantscan vary their individual contributions for voluntarily providing apublic good. As time goes by, participants either in(de)crease their contributiongradually or keep it constant. Groups of two poorly and two...

We perform an experimenta linvestigation using a dictator game inwhich individuals must make a moral decision —to give or not to give anamount of money to poor people in the Third World. A questionnaire inwhich the subjects are asked about the reasons for their decision showsthat, at least in...

´This paper aims to analize the role of personal identity indecision making. To this end, it starts by reviewing criticallythe growing literature on economics and identity. Consideringthe ambiguities that the concept of social identity poses, our proposalfocuses on the concept of personal...

Even though decision-making in small teams is pervasive in business and in private life, littleis known about subjects’ preferences with respect to individual and team decision-making andabout the consequences of respecting these preferences. We report the results from anexperimental...

Economics has devoted little attention so far as to whether the type of decision maker matters for economic decisions. However, many important decisions like those on monetary policy or a company’s business strategy are made by (small) groups rather than an individual. We compare behaviour of...

Many decisions in economics and finance have to be made under severe time pressure. Furthermore, payoffs frequently depend on the speed of decision-making, like, for instance, when buying and selling stocks. In this paper, we examine the influence of time pressure and time-dependent incentive...

We experimentally investigate whether individuals can reliably detect cooperators in an anonymous decision environment by allowing participants to condition their choices in an asymmetric prisoner's dilemma and a trust game (i) on their partner's donation share to a self-selected charity, and...

We report some experiments conducted to test whether ambiguity influences behavior in a coordination game. We study the behavior of subjects in the presence of ambiguity and attempt to determine whether they prefer to choose an ambiguity safe option. We find that this strategy, which is not...

Belief elicitation is important in many different felds of economic research. We show that how a researcher elicits such beliefs-in particular, whether the belief is about the participant's opponent, an unrelated other, or the population of others-affects the processes involved in the formation...

Whereas many others have scrutinized the Allais paradox from a theoretical angle, we study the paradox from an historical perspective and link our findings to a suggestion as to how decision theory could make use of it today. We emphasize that Allais proposed the paradox as a normative argument,...
