Migrations have intensified with the advent of globalisation. Societies once solidly monocultural are becoming increasingly multicultural. It is, however, not clear how social capital would travel across cultural boundaries. A multicultural environment might result on agents preferring to...

This paper compares individual with collective contracts using modified repeated gift exchange games. The game had two variations, both following a partner design. In the individual variation different workers in the same firm can receive separate wages, and in the collective variation all...

In this paper we consider data from a large number of economic experiments, and look for demographic effects that may be a source of subject pool bias if not carefully accounted for in the subsequent statistical analysis. Our dataset contains information on 2,408 subjects and 597 experimental...

We study individual decision making in a lottery-choice task performed by three subject populations: gamblers under psychological treatment (“addicts”), gamblers’ relatives (“victims”), and normal (as far as gambling is considered) individuals. We find that addicts are willing to take...

This study explores how a self-fulfilling prophecy can solve a social dilemma. We ran two experimental treatments, baseline and automata. Both consisted of a finitely repeated public goods game with a surprise restart. In the automata treatment it was announced that there might be automata...

Experimental subjects usually self-select to the laboratory and this may introduce a bias to the derived conclusions. We analyze data stored by a subject-pool management software at an experimental laboratory and speculate about the eect of individual decisions on returning. In particular, we...

We propose an intergroup competition scheme (ICS) to solve the free-riding problem in the public goods game. Our solution only requires knowledge of the group contributions, is budget balanced and with the right parameters a dominant strategy. The main innovations of our design are that the...

This is a study about the possibility of self-governance. We designed two versions of a step-level public good game, with or without a centralized sanctioning mechanism (CSM). In a baseline treatment participants play 14 rounds of the non-CSM game. In an automatic removal (AR) treatment...

This study uses a novel application of priming to provide experimental evidence that aspirations and social comparisons may be influenced by non factual sources. A textual narrative eliciting social comparison is shown to dramatically alter material aspirations. This is despite the narrative not...

We compare individual with collective contracts using variations of a repeated gift- exchange game. Firms consist of one employer and three workers. In the individual variation (I) different workers can receive separate wages. In the collective variation (C) workers receive the same wage. I and...
