Title : Framing and cooperation in public good games: an experiment with an interior solution.

Author(s) : Marc WILLINGER, Anthony ZIEGELMEYER

Abstract : We show that experimental subjects tend to contribute more to the public good if they perceive the actions of the others as a source of positive externality rather than a source of negative externality. In our experiment partial contribution to the public good is the unique subgame perfect equilibrium for the repeated game.

Key-words : Experimental economics; Public goods
