We study the implications of two solidarity conditions on the efficient location of a public good on a cycle, when agents have single-peaked, symmetric preferences. Both conditions require that when circumstances change, the agents not responsible for the change should all be affected in the...

We construct a simple three person trust game with one trustor and two trustees. The trustor has the possibility to either trust both trustees or none, while the trustees make their decisions either sequentially or simultaneously, depending on the treatment. When trustees play sequentially,...

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be su cient to make all agents in the river cooperate and acknowledge property rights as a prerequisite for...

We test a mechanism whereby groups are formed voluntarily, through the use of voting. These groups play a public-goods game, where efficiency increases with group size (up to a limit, in one treatment). It is feasible to exclude group members, to exit one's group, or to form larger groups...
