A comment on "Is having more channels really better? A model of competition among commercial television broadcasters"

his paper shows that the analysis of Liu et al. (2004) contains a substantive error-the asserted pure-strategy Nash equilibrium leading to their Theorems I and 2 is really not an equilibrium. We show that in their model, either pure-strategy Nash equilibria do not exist or, unlike their asserted main result, when a pure-strategy equilibrium exists, increasing the number of commercial television broadcasters does not result in lower-quality programs. Possible modifications of Liu et al.'s model that may help restore the desired result are discussed.
