Two duopolists compete in price on the market for a homogeneous product. They can ‘profile’ consumers, i.e., identify their valuations with some probability. If both firms can profile consumers but with different abilities, then they achieve positive expected profits at equilibrium. This...

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...

This paper develops a new sufficient statistic approach for estimating the marginal internality from sin good consumption. It models a biased consumer who faces uncertain health harms and receives mandatory health insurance. I show that the marginal internality can be identified by observing how...

Non-communicable diseases (NCDs) cause about 71% of all deaths globally and a considerable increase in health care costs. To tackle this problem, several Governments have designed "sin taxes", i.e, extra payments related to the quantity of unhealthy contents of specific goods. However, unhealthy...

Non-governmental organizations (NGOs) are exerting growing pressure on firms to eliminate product components (such as palm oil) that are harmful to the environment (such as rainforests) or replace such components with NGO-certified sustainable components. Under which conditions does NGO pressure...

This paper addresses the question whether taxes on unhealthy food are suitable for internalizing intergenerational externalities inflicted by parents when they decide on their children's diet. Within an OLG model with an imperfectly altruistic parent, the optimal steady state tax rate on...

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...

The objective of this paper is to explain populist attitudes that are prevailing in a number of European democracies. Populist attitudes expectedly lead to social protests and populist votes. We capture the populist wave by relying not on voting behavior but rather on values that are...
