We study individual behaviour in a repeated linear public good experiment in which, in each period, subjects are required to contribute a minimum level and face a certain probability to be audited. Audited subjects who contribute less than the minimum level are convicted to pay the difference...

We present results from an experiment with multiple public goods, where each good produces benefits only if total contributions to it reach a minimum threshold. The experiment allows us to compare contributions in a benchmark treatment with a single public good and in treatments with more public...

Experiments involving multiple public goods with contribution thresholds capture many features of charitable giving environments in which donors try to coordinate their contributions across various potential recipients. We present results from a laboratory experiment that introduces endowment...

This paper studies contributions and punishments in a linear public good game, where group members have different sources of endowment. We compare the behavior of homogeneous groups, in which subjects are exogenously assigned the same endowments, with that of heterogeneous groups, in which half...
