In two laboratory studies involving 285 undergraduate students presented with a one-shot real choice we observe a systematic influence of time delay on the preferences for two lotteries, equal in expected value, but different in the degree of probability and outcome. The more the outcome is...

In this paper, attitude and trust are studied in the context of a food scare (dioxin) with the aim of identifying the components of attitude and trust that significantly affect how purchases are determined. A revised version of the model by MAYER et al. (1995) was tested for two types of food:...

This is an experiment on the effect of norm application in a public good game. We want to investigate whether a control norm affects the contribution level differently, only in relation to the way in which the norm is applied in the game. We compare the amount of public good provided in two...

Inspired by Karl Polanyi’s writings on three allocation modes, namely reciprocity, exchange and redistribution, we first tested a reciprocity ring with ten players. The baseline treatment, with no possibility of socialisation, displayed very low levels of allocative efficiency. Consistently...

We experimentally investigate social effects in a principal-agent setting with incomplete contracts. The strategic interaction scheme is based on the well-known Investment Game (Berg et al., 1995). In our setting four agents (i.e., trustees) and one principal (i.e., trustor) are interacting and...
