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 introduce the concept of "group cohesion" to study the economic consequences of social relationships in team production. We measure group cohesion, adapting the "oneness scale" from psychology to group level. A series of experiments, including a pre-registered replication, reveals that higher...

This paper reports a new and significant experimental demonstration that market participants adjust their bids towards the price observed in previous market periods when - by design - individuals' values should not be affiliated with the market price. This demonstration implies that market...

The "grammar of trust" is one the most explored loci in game theory and behavioural economics. However, still much needs to be understood about the nature of trust in non-enforceable, personalised interactions, in markets and within organizations. This experimental study aims at contributing to...

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...

The 'grammar of trust' is one of the most explored loci in behavioural and experimental economics. This experimental study aims at contributing to the understanding of new dimensions of trust by exploring how risky trust may foster a trustee's behavioural change. It investigates trustee's...

It is commonly assumed that friendship should decrease strategic uncertainty in games involving tacit coordination. However, this has never been tested on two "opposite poles" of coordination, namely, games of strategic complements and substitutes. We present an experimental study having...

It is commonly assumed that friendship should generally benefit agents' ability to tacitly coordinate with others. However, this has never been tested on two "opposite poles" of coordination, namely, games of strategic complements and substitutes. We present an experimental study in which...

We introduce "group cohesion" to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the "oneness scale" from psychology. A series of experiments, including a pre-registered replication, reveals strong positive...

Friendship is commonly assumed to reduce strategic uncertainty and enhance tacit coordination. However, this assumption has never been tested across two opposite poles of coordination involving either strategic complementarity or substitutability. We had participants interact with friends or...
