Abstract

We use a sequential voluntary contribution game to compare the relative impact of firstmover’s
non-binding announcement versus binding commitment on cooperation. We find that
non-binding announcement and binding commitment increase individual contributions to a
similar extent. Since announced contributions systematically exceed commitments, in sessions
with non-binding announcement, second-movers tend to contribute more to the group activity
than in sessions with 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
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.
