Abstract of associated article: When agents face coordination problems their choices often impose externalities on third parties. If an agent cares about them or believes others do, they can affect equilibrium selection. We present evidence from lab experiments showing that changes in the size and the sign of third-party externalities have a significant impact on tacit coordination. Decision makers are more willing to incur a cost to try to avoid imposing a large negative externality on a third party, than they are to avoid a small negative externality or to generate a large positive externality. However, when decision-makers' incentives are at odds with the interests of third parties, many of them appear to ignore third-party externalities even if they are large in magnitude, and ignoring them implies substantial earning inequalities and reductions in group earnings. Individuals revealed to be other-regarding in a non-strategic allocation task often behave as-if selfish when trying to coordinate. We discuss explanations for our findings.
