Consumer boycotts often provide a disciplinary mechanism against firms deviating from established social norms. Such actions tend to be organized by people through reference groups with a social mission. The intensity of the group identity is, however, private information. Therefore, the...

Habits are an important cause of sluggish consumption adjustment in response to price shocks. This paper studies shifts within the consumption bundle under endogenous habit formation. I put forward a model with good-specific, or 'deep', habits that cause persistence in good-specific consumption....

Standard media economics models imply that increased platform competition decreases ad levels and that mergers reduce per-viewer ad prices. The empirical evidence, however, is mixed. We attribute the theoretical predictions to the combined assumptions that there is no advertising congestion and...

This paper analyzes persuasive advertising and pricing in oligopoly if firms sell differentiated products and consumers have heterogeneous social attitudes towards the consumption by others. Deriving product demand from primitives, we show that the demand-enhancing effect of persuasive...

Afriat (1967) showed the equivalence of the strong axiom of revealed preference and the existence of a solution to a set of linear inequalities. From this solution he constructed a utility function rationalizing the choices of a competitive consumer. We extend Afriat's theorem to a class of...

We study the relation between ad networks, consumer privacy and the online advertising market. We consider two publishers that can outsource their ad inventories to an ad network, in a market where consumers and advertisers endogenously multi-home. Differently from publishers, the ad network...

We study optimal pollution abatement under a mixed oligopoly game when firms engage in emissions-reducing R&D that is imperfectly appropriable. The regulator uses a tax to curb emissions. Results show that in a mixed oligopoly, the public firm has positive emissions reduction in equilibrium;...
