We use a sequential voluntary contribution game to compare the relative impact of a first-mover’s non-binding announcement versus binding commitment on cooperation. We find that a non-binding announcement and a binding commitment increase individual contributions to a similar extent. Since announced contributions systematically exceed commitments, in sessions with a non-binding announcement, second-movers tend to contribute more to the group activity than in sessions with a binding commitment. Yet, second-movers appear to be more motivated towards achieving a social optimum when the (...) first-mover uses commitment. We also find that a non-binding announcement has a higher impact on individual propensity to cooperate than the ex post contribution of the first-mover. However, the failure to make announced contributions decreases cooperation even though the first-mover is reassigned in every period. (shrink)

We investigate the limits of communication and leadership in avoiding coordination failure in minimum effort games. Our environment is challenging, with low benefits of coordination relative to the effort cost. We consider two leader types: cheap-talk leader-communicators who suggest an effort level, and first-mover leaders who lead by example. Both types of leadership have some ability to increase effort in groups with no history, but are insufficient in groups with a history of low effort. Using the strategy method for followers’ (...) responses, we attribute the persistence of coordination failure to the presence of followers who do not follow the leader. (shrink)

Originally published in 1941, this book contains the French text of Jean-Jacques Rousseau's 1755 treatise Discours sur l'origine et les fondements de l'inégalité parmi les hommes, in which he examines the artificial origins of human social structures designed to keep one group elevated above another. The preface by F. C. Green provides the historical context for Rousseau's essay and explains its influence on the authors of the French Revolution. This book will be of value to anyone with an interest in (...) French history or political philosophy. (shrink)
