Cheap Talk Games: Comparing Direct and Simplified Replications

To study strategic information transmission in organizations, we conduct a simplified version (with only three states) of the sender-receiver game experiment designed by Wang, Spezio, and Camerer (2010), in which an informative sender advises an uninformed receiver to take an action (to match the true state), but has incentives to exaggerate. We also have the same subjects play the original five-state game. We find similar “overcommunication” behavior with Taiwanese subjects – messages reveal more information about the true state than what equilibrium predicts – that let us classify subjects into various level-k types. However, results from the simplified version are closer to equilibrium prediction, with more senders robustly classified as level-2.
