We experimentally disentangle two potential sources for endogenous social interactions effects. By comparing groups where the group norm is publicly observable with those where it is not we can measure the size of any endogenous observation effect. By comparing connected with disconnected groups...

People are shown to be “more (less) trusting as others are on average more (less) trusting” in a binary-choice-with-social-interactions model that is estimated using cross-section data from more than sixty countries, with mean trust as an explanatory variable. These endogenous effects...

This article establishes that there are significant social influences on the decisions made by individuals about whether to trust others. These social interactions effects may arise from exogenous-environmental characteristics or from endogenous effects that make people conform to the particular...

The idea that people follow trust norms when making trust decisions is developed in an evolutionary model of adaptive play by boundedly rational agents. Because it neither implies nor is it implied by cooperation, trust is not modelled as cooperation in a Prisoners' Dilemma but as a coordination...

We experimentally study the impact of framing effects in a repeated sequential social dilemma game. Our between-subjects design consists of two group level (“Wall Street” vs. “Community”) and two individual level (“First (Second) Movers” vs. “Leaders (Followers)”) frames. We find...
