We study a two-stage R&D project with an abandonment option. Two types of uncertainty influence the decision to start R&D. Demand uncertainty is modelled as a lottery between a proportional increase and decrease in demand. Technical uncertainty is modelled as a lottery between a decrease and...

We study a two-sided market where a platform attracts firms selling differentiated products and buyers interested in those products. In the unique subgame perfect equilibrium of the game, the platform fully internalizes the network externalities present in the market and firms and consumers all...

To account for the illegal nature of price-fixing agreements, detection probabilities are introduced in a dynamic oligopoly. It follows that for a trigger strategy to sustain a non-cooperative collusive equilibrium as a SPNE both the discount rate and all per-period detection probabilities have...

A monopolist in public transport may oversupply frequency relative to the social optimum, as van Reeven (2008) demonstrates with homogeneous consumers. This result generalizes for heterogeneous consumers who know the timetable. Whether a monopolist oversupplies or undersupplies frequency depends...

An increase in cartel discovery probability due to irregular price movements that result from cartel defection is shown to increase cartel stability as short-run defection profits are less likely to be earned.

This paper studies the relationship between three key elements of the marketing mix, namely, price, product, and promotion, in a model where a seller employs informative advertising to launch a new product. We propose a fairly general advertising technology for the study of three promotional...

The condition is derived for Friedman 's trigger strategy to sustain a collusive market equilibrium as a noncooperative Nash equilibrium given subjective beliefs as to the antitrust authority's ability of suc- cesfully dissolving the illegal cartel.

This paper shows how a firm can use non-targeted advertising to exploit consumers' desire for social status. A monopolist sells multiple varieties of a good to consumers who each care about what others believe about his wealth. Advertising allows consumers both to buy different varieties and to...

Evolutionary and environmental economics have a potentially close relationship. This paper reviews past and identifies potential applications of evolutionary concepts and methods to environmental economics. This covers a number of themes: resource use and ecosystem management; growth and...
