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...

A number of competing social preference models have been developed inspired by the evidence from economic experiments. We test the relative performance of some of these models using an experimental design that is aimed at capturing pure distributional concerns in a multi-person setting. We find...

By using hypothetical choice experiments, this paper presents evidence that individuals' concern for relative consumption depends on their relative consumption. Individuals with consumption levels above society's average consumption level tend to have, in general, lower concern for relative...

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods...

In the vast majority of laboratory experiments documenting the existence of reciprocity subjects are endowed with windfall funds. In many environments with salient fairness considerations such endowments are known to inflate subjects’ other-regarding behavior, thereby creating a so-called...

We conduct a laboratory experiment to study whether giving people more time to donate to charity reduces donations. People may intend to donate, but because of the transaction costs of doing so, postpone making the payment until they are less busy, and having postponed making the donation once,...

We contribute to the theory of the firm by experimentally investigating a bilateral trade relationship in which standard theory assuming self-regarding preferences predicts that the seller will be better off by investing in the outside option to improve his bargaining position. The seller’s...

We study whether group identity helps mitigate inefficiencies associated with appropriable quasi-rents, which are often created by relationship-specific investments in bilateral trade relationships. Based on previous findings that group identity strengthens other-regarding preferences, we...

We develop, and experimentally test, models of informal agreements. Agents are assumed to be honest but suffer costs of overcoming temptations. We extend two classical bargaining solutions -- split-the-difference and deal-me-out -- to this informal agreement setting. For each solution there are...
