Using a two-period duopoly model with vertical differentiation, we show that there exists a unique subgame perfect equilibrium where the first entrant supplies a lower quality and gains higher profits than the second entrant. We also prove that this entry sequence is also socially efficient.

We analyse a model of vertical differentiation focusing on the trade-off between entering early and exploiting monopoly power with a low quality, versus waiting and enjoying a dominant market position with a superior product. We show that, in a relevant parameter region, there exists a unique...

We consider a market for vertically differentiated goods where firms enter over time, after having developed innovations characterised by different quality levels. We show that patent height and length interact to determine the ultimate emergence of duopoly. In general, imposing quality...

We study a Bertrand game where two sellers supplying products of different and unverifiable qualities can outwit potential clients through their (costly) deceptive advertising. We characterize a class of pooling equilibria where sellers post the same price regardless of their quality and low...

There are two competing sellers of an experience good, one offers high quality, one low. The low-quality seller can engage in deceptive advertising, potentially fooling a buyer into thinking the product is better than it is. Although deceptive advertising might seem to harm the buyer, we show...

We study a game in which two competing sellers supplying experience goods of different quality can induce a perspective buyer into a bad purchase through (costly) deceptive advertising. We characterize the equilibrium set of the game and argue that an important class of these outcomes features...

We study a competitive insurance market in which insurers have an imperfect informative advantage over policyholders. We show that the presence of insurers privately and heterogeneously informed about risk can explain the concentration levels, the persistent profitability and the pooling of risk...
