We investigate the welfare implications of unfair incentive contracts in comparison with interactions without contracts. Reciprocal people should cooperate conditionally in the latter situation but punish unfairness by non-cooperation. We confirm that some people do cooperate conditionally in a...

This paper investigates whether providing strong cooperation incentives only at the outset of a group interaction spills over to later periods to ensure cooperation in the long run. We study a repeated linear public-good game with punishment opportunities and a parameter change after the first...

This paper presents experimental evidence that tax compliance is path dependent. We show that individuals faced with the same current tax enforcement parameters, will nevertheless choose different compliance if they have faced different tax enforcement parameters in the past. This finding has...

This paper presents experimental evidence that contributions to a public good can be path-dependent for a limited time span. We study a repeated linear public-good game with punishment opportunities. Our data shows that subjects who had experienced a higher marginal return on public-good...

Two pairs of two participants each interact repeatedly in two structurally independent but informationally linked Prisoner's Dilemma games. Neither pair receives feedback about past choices by their own partner but is fully informed about the choices by the other pair. Considering this as a...

This paper presents experimental evidence that tax compliance is path dependent. For given values of the audit probability and the fine for tax evasion, we compare the income declaration of subjects who faced a change in one of the two parameters to that of subjects who experienced no such...
