| Abstract: |
We consider a model of a TV oligopoly where TV channels transmit advertising
and viewers dislike such commercials. We show that advertisers make a lower
profit the larger the number of TV channels. If TV channels are sufficiently
close substitutes, there will be underprovision of advertising relative to
social optimum. We also find that the more viewers dislike ads, the more
likely it is that welfare is increasing in the number of advertising financed
TV channels. A publicly owned TV channel can partly correct market
distortions, in some cases by having a larger amount of advertising than
private TV channels. It may even have advertising in cases where advertising
is wasteful per se. |
