Three essays on leadership and cooperation in public good games

The issues explored in this thesis concerns public good games. We tackle the topic from di erent prospectives focusing on leadership and cooperation. Each chapter considers public good games from di erent angles. In the first chapter, we analyse reference dependent agents (that use a reference point to determine their choices) and standard agents who interact in simultaneous or in sequential public good situations. The second chapter consists of a sequential repeated public good experiment where subjects participate to a competitive mechanism to become leader in a group. Finally, in the third chapter, we study the implication of non- and semi-parametric methods in the re-analysis of two well-known public good experiments.
