Optimum intérieur et financement efficient d'un bien public :une expérience
This experiment provides results in voluntary contribution for a public goods using a payoff function which defines a Pareto optimum inside the strategic contributions space. Two optima are tested. One is defined at 30% of the subjects' endowment, an the other at 70%. The Nash equilibrium of these games remains the non contribution to the public good. The experiment results show that the over but inefficient contribution is not due to a confusion made by the subjects but is rather due to the subjects' voluntary decision. Next, a public good is easily provided when the optimal point is defined at a low contribution level, even if it is not always fully provided. This last results highlight a coordination problem to reach the social optimum, and identify two behaviors named Reactive Behavior and Optimum Lover.
