Advertising in a social network as a signal of quality
In: Moscow University Economics Bulletin, Heft 2, S. 118-139
Abstract
Advertising in a social network has a number of characteristics that distinguish it from other types of advertising, and which may be of key importance in answering the question about its ability to serve as a signal of quality. In the game-theoretic model presented in this paper, the monopolist sends an advertising signal to bloggers who act as "opinion leaders" in the social network. The latter, in turn, make decisions about posting advertising messages on their blogs, taking into account the impact that this action may have on their reputation. The paper investigates the question of when advertising can serve as a reliable signal of quality in a separating equilibrium.
