Recent experimental studies find excessive truth-telling in sender-receiver games. We show that this phenomenon is robust to the random intervention of a truthful regulator. In addition, intervention significantly increases the excessive trust of receivers while the overall percentage of...

Conditional commitment devices such as price matching guarantees or legal contracts can be highly efficient and improve the outcomes for involved parties. In the context of public goods, however, empirical evidence on the cooperation-enhancing effect of conditional commitments is scarce. In this...

We report results from a laboratory experiment that explores the effects of preference communication and leader selection mechanisms in group decision-making.
