Abstract
Demichelis & Weibull (AER 2008) show that adding lexicographic lying costs to
coordination games with cheap talk yields a sharp prediction: only the efficient
outcome is evolutionarily stable. I show that this result is caused by the discontinuity
of preferences rather than by small lying costs per se. Finally, I discuss
why discontinuity may not be an appealing assumption in evolutionary models.
