Cooperation is central to human existence, forming the bedrock of everyday social relationships and larger societal structures. Thus, understanding the psychological underpinnings of cooperation is of both scientific and practical importance. Recent work using a dual-process framework suggests...

In development policy and practice, support to or interventions in value chains are considered to be instrumental for achieving outcomes such as poverty alleviation. This paper reviews methodological discussions on how to show the effects and workings of value chain support in a context of...

We review two fundamentally different ways that decision time is related to cooperation. First, studies have experimentally manipulated decision time to understand how cooperation is related to the use of intuition versus deliberation. Current evidence supports the claim that time pressure (and,...

Recently, the positive theory of rational choice has come under attack from experimental psychologists and economists. Their experimental results, gathered together under the banner of behavioral analysis, show that the maximizing model of rational choice often does not provide a very accurate...

This study examines whether charitable giving increases if donors have more choice about how their donations are used. In a field experiment, employees of large Albanian companies were asked to donate to projects administered by Down Syndrome Albania. Treatments varied in whether participants...

Using survey experiments in the United States and Germany with 12,000 participants, we examine perceptions of life expectancy inequality between rich and poor people. The life expectancy of the poor is underestimated more than that of the rich, leading to exaggerated perceptions of inequality in...

We report on the results of an experiment designed to disentangle behavioral biases in information aggregation of committees. Subjects get private signals about the state of world, send binary messages, and finally vote under either majority or unanimity rules. Committee decisions are...

Recent studies suggest that cooperative decision-making in one-shot interactions is a history-dependent dynamic process: promoting intuition versus deliberation has typically a positive effect on cooperation (dynamism) among people living in a cooperative setting and with no previous experience...

A long time ago most economists would have limited themselves to stating that agreements should be individually rational and efficient and that selecting a specific agreement from that set depends on bargaining and negotiation power whatever that may be. Nowadays hardly any economist will argue...
