We show how increased competition in a media market may have implications for the competition between firms that are advertising in that medium. We apply a simple model of a product market with network externalities where firms buy advertising space in a media market and find that there is more...

This paper analyses how competition between media firms influences the way they are financed. In a setting where monopoly media firms choose to be completely financed by consumer payments, competition may lead the media firms to be financed by advertising as well. The closer substitutes the...

We consider a model of strategic informative advertising where the advertising is done on TV and where the TV channels' advertising prices are endogenously determined. We discuss how these prices, and the advertising firms' advertising efforts, vary with the two key parameters of the model: the...

The key to an understanding of the TV industry is the market for TV advertising. We present a model of this market that also encompasses the product markets and the viewer market. Because viewers dislike commercials, there is congestion in advertising, and TV channels offer complementary goods...

By combining a theory of herding behavior with the phenomenon of availability heuristic, this paper shows that non-informative advertisements can affect people’s choices by influencing their perception of product quality. We present a model in which people can learn about product quality by...

We present a theory of how advertising can break a lock-in by distorting beliefs about market shares in markets with network externalities. On the background of the availability heuristic we assume that people learn about market shares by observing product adoption of others, but are not able to...

We consider a model where TV channels transmit advertising, and viewers dislike such commercials. We find that the less differentiated the TV channels’ programs are, the lower is the amount of advertising in equilibrium. Relative to the social optimum, there is underprovision of advertising if...

Research on productive efficiency at the firm level has developed as an important and active strand of research the last decades, both within operations research, management science and economics. However, the interests pursued within the fields have had some differences regarding sound...

Catastrophic risk is currently a hotly debated topic. This paper contributes to this debate by showing two results. First it shown that the value function in dynamic optimization can have an infinite derivative at some point even if the model specification has functional forms that are finite...

An intertemporal optimal strategy for accumulation of reversible capital and management of an exhaustible resource is analyzed for a global economy when resource depletion generates discharges that add to a stock pollutant that affects the likelihood for hitting a tipping point or threshold of...
