We introduce the concept of "group cohesion" to capture the economic consequences of ubiquitous social relationships in group production. We measure group cohesion, adapting the "oneness scale" from psychology. A comprehensive program of new experiments reveals the considerable economic impact...

We report two studies investigating whether, and if so how, different interventions affect voter registration rates. In a natural field experiment conducted before the 2015 UK General Election, we varied messages on a postcard sent by Oxford City Council to unregistered student voters...

Experimental research has shown that ordinary people often perform remarkably well in solving coordination games that involve no conflicts of interest. While most experiments in the past studied such coordination games among socially distant anonymous players, here we study behaviour in a set of...

According to the Description-Experience gap (DE gap), people act as if overweighting rare events when information about those events is derived from descriptions but as if underweighting rare events when they experience them through a sampling process. While the is now clear evidence that the DE...

We investigate whether relative performance feedback can create biases in confidence leading it to 'snowball'. We study elicited confidence about own performance, relative to other group members, in three stages. As subjects move across stages, we change group composition so that new groups...
