Abstract:

We utilize a laboratory experiment with two 2-player dominance-solvable games to quantify how a payo-irrelevant truth aects player behavior. While the truth substantially aects participants' choices in both games, the eect is greater in the game without a dominant strategy. Shares of consistently truthful participants are similar across the games, suggesting that fundamentally honest people are unaected by strategic environments. The share of occasionally truthful participants, however, is larger, and the average lie size is smaller in the game without a dominant strategy. Tacit coordination around the commonly-known truth in that game boosts payos, signifying truthfulness as a strategic decision.
