We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting (Varian, Journal of Public Economics, 1994). Our findings support the theoretical argument that sequential contributions result in lower overall provision than...

We study the effect of group size on cooperation in voluntary contribution mechanism games. As in previous experiments, we study four- and eight-person groups in high and low marginal per capita return (MPCR) conditions. We find a positive effect of group size in the low MPCR condition, as in...

We investigate social norms for dictator game giving using a recently proposed norm-elicitation procedure (Krupka and Weber, 2013). We elicit norms separately from dictator, recipient, and disinterested third party respondents and find that elicited norms are stable and insensitive to the role...

Previous experiments have found a moderate, positive effect of group size on cooperation in voluntary contribution mechanism (VCM) games. This effect has been typically observed in experiments with groups of size 4 or more, and contrasts with results from n-person prisoner’s dilemma and...

We experimentally investigate a repeated “inspection game†where, in the stage game, an employee can either work or shirk and an employer simultaneously chooses to inspect or not inspect. The unique equilibrium of the stage game is in mixed strategies with positive probabilities of...

This paper investigates how social comparison information about referent others (i.e. learning what similar others do and how they are treated) affects reciprocal relationships. Using a three-person gift-exchange game we study how employees’ reciprocity towards an employer is affected by...
