We study the behavior of football (soccer) referees in the German Bundesliga. Referees are requested to act as impartial agents. However, they may be tempted to allocate benefits and rewards in a biased way. Agency theory has long neglected this form of malfeasance of economic agents, but has...

We examine the degree of trust and reciprocity in an experimental trust game with 662 participants from six different age groups, ranging from 8 year old primary school children to retired persons in their late sixties. Although both trust and reciprocity have been identified as fundamental...

We compared the behavior of groups and individuals in a two-person trust game. The first mover in this game, the sender, receives an endowment and can send any part of it to the responder; the amount sent is tripled, and the responder can then return to the sender any portion of the tripled sum....

We test for behavioral differences between groups and individuals in gift-exchange experiments. Related studies establish group behavior as typically closer to the game-theoretic equilibrium. We show that this result may depend crucially on the decision making procedure within groups. A novel...

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 examine the publications of authors affiliated with an economics research institution in Canada in (i) the Top-10 journals in economics according to journals' impact factors, and (ii) the /Canadian Journal of Economics/. We consider all publications in the even years from 1980 to 2000....

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...

Economic decisions have been shown to depend on actual outcomes as well as perceived intentions. In this paper, we examine whether and how the relative importance of outcomes or intentions for economic decision develops with age. We report the result of ultimatum games with children, teens and...

Direct democracy with its use of referenda avoids the prototypical principal-agent problems of delegation in indirect democracies, especially since elected representatives are usually not committed by law to keep their promises. Sequential or more complex referenda may, however, result in an...

In a large scale newspaper experiment 5,132 readers of the German weekly, Die Zeit, participated in a three-person bargaining game. In our data analysis we focus on (1) the influence of age, gender, profession and the medium chosen for participation on bargaining behavior and on (2) the external...
