In diesem Beitrag diskutieren wir den in der Literatur heftig umstrittenen Aspekt, ob Vertrauen (Institutionen) nur ein Komplement zu formellen Institutionen (Vertrauen) sein oder diese(s) möglicherweise sogar substituieren kann (können). Wir fassen Vertrauen als spezifische, kooperative...

The aim of this paper is threefold: we first discuss the appropriateness of the traditional trust-game-tree for the analysis of trust relationships. Following the definition put forward by Lee et al. (2005) that confident expectations and a willingness to be vulnerable are critical components of...

We conduct a laboratory experiment to analyze the effect transactions costs and inertia have on charitable giving. We conjecture that transaction costs will have a greater effect on donations if the solicitation is received when the opportunity cost of time is high. Inertia could become a factor...

In the vast majority of experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In some situations such endowments might create a so-called “house money effect”. We identify two reasons why the source of endowment might matter for negative reciprocity:...

Both the law and culture make a central distinction between acts of commission that overturn the status quo and acts of omission that uphold it. In everyday life acts of commission often elicit stronger reciprocal responses than do acts of omission. In this paper we compare reciprocal responses...

Previous research has suggested that communication and especially promises in-crease cooperation in laboratory experiments. This has been taken as evidence for internal motivations such as guilt aversion or preference for promise keeping. The goals of this paper are to examine messages under a...

The hold-up problem has played a central role in the study of firm boundaries, which is a fundamental element of the economic study of organizations. We study a previously unex-plored mechanism by which integration between two parties could resolve the problem. Based on the social identity...

We study the effect of the addition of a futures market, in which contracts maturing in the last period of the life of the asset can be traded. Our experiment has two treatments, one in which a spot market operates on its own, and a second treatment in which a spot and futures market are active...

In this paper we use laboratory experiments to test the theoretical predictions derived by Villegas-Palacio and Coria (2010) about the effects of the interaction between technology adoption and incomplete enforcement. They show that under Tradable Emissions Permits (TEPs), and in contrast to...

Common identity and peer punishment have been identified as important means to reduce free riding and to promote cooperation in teamwork settings. This paper examines the relative importance of these two mechanisms, as well as the importance of income distribution in team cooperation. In a...
