This paper compares the performance of alternative estimation approaches for Public Goods Game data. A leave-one-out cross validation was applied to test the performance of five estimation approaches. Random effects is revealed as the best estimation approach because of its un-biased and precise...

We propose an intergroup competition scheme (ICS) to theoretically solve free-riding in team production and provide experimental evidence from a voluntary contribution mechanism (VCM) public goods game. The ICS includes an internal transfer payment from the lowest to highest contributing team...

We propose an intergroup competition scheme (ICS) to solve the free-riding problem in the public goods game. Our solution only requires knowledge of the group contributions, is budget balanced and with the right parameters a dominant strategy. The main innovations of our design are that the...
