Ethics is a field in which the gap between words and actions looms large. Game theory and the empirical methods it inspires look at behavior instead of the lip service people sometimes pay to norms. We believe that this special issue comprises several illustrations of the fruitful application of...

The notion of choice inconsistency is widely spread in the literature on behavioral economics. Several approaches were used to account for the observation that people reverse their choices over time. This paper aims to explain the formation of resolutions regarded as internal self-binding...

Absentmindedness is a special case of imperfect recall which according to Piccione and Rubinstein (1997a) leads to time inconsistencies. Aumann, Hart and Perry (1997a) question their argument and show how dynamic inconsistencies can be resolved. The present paper explores this issue from a...

Euro coins have a common European side and an individual national side. Thanks to coin migration, coins bearing a panoply of national sides are in circulation throughout the euro area. In this paper, we model the mixing of coins circulating in the euro area countries and in particular the extent...

Hypocrisy is the act of claiming moral standards to which one's own behavior does not conform. Instances of hypocrisy, such as the supposedly green furnishing group IKEA's selling of furniture made from illegally felled wood, are frequently reported in the media. In a controlled and incentivized...

We explore aversion to the use of algorithms in moral decision-making. So far, this aversion has been explained mainly by the fear of opaque decisions that are potentially biased. Using incentivized experiments, we study which role the desire for human discretion in moral decision-making plays....

Cash payments are simple, secure, efficient and anonymous and therefore popular with consumers. At the same time, these properties also make cash a focal point for potential illegal uses. An oft-voiced opinion in the public debate is that cash promotes the shadow economy and is used as a means...

There is an ongoing debate about genetic engineering (GE) in food production. Supporters argue that it makes crops more resilient to stresses, such as drought or pests, and should be considered by researchers as a technology to address issues of global food security, whereas opponents put...

This article explains the emergence of an unique equilibrium resolution as the result of a compromise between two selves with different preferences. The stronger this difference is, the more generous the resolution gets. This result is in contrast to predictions of other models in which sinful...

We study the influence of taxation on labour supply using a specifically designed representative survey of the German population. First, we investigate whether taxes generally matter for the labour supply decisions of our respondents. Around 41 per cent report taking taxes into consideration,...
