Abstract
We experimentally investigate communication in sender-receiver games with imperfect incentive alignment. We consider both
a priori meaningless messages and messages with pre-established meanings. Under four canonical incentive conditions, we get communication outcomes. However, it is by no means a fait accompli. We observe significant deterioration and recoding of
a priori meanings, sucker behavior by receivers, and focal point and initial condition effects. A conservative
partial common interest (PCI) condition generally is a reliable, albeit coarse predictor of the form of communication. Equilibrium selection criteria sometimes improve on the PCI prediction but neither
influentiality, ex ante efficiency, nor Farrell's
neologism-proofness refinement is reliable across all games, and equilibria are not always obtained. Considering comparative statics, equilibrium selection criteria are helpful but imperfect predictors of how equilibrium frequencies respond to incentives, whereas the less ambitious PCI prediction is never rejected by the data.
