In a vertical differentiation model, we investigate whether the property of finiteness holds when the average cost function depends on the quantity. We prove that this property holds when the cost function has increasing returns. In the case of cost functions with decreasing returns, we prove...

The paper studies how second degree price discrimination can be implemented in a duopoly with differentiated products. Two firms serve consumers having heterogeneous willingness to pay for the good, willingness to pay being private knowledge. Consumers choose from a menu of tariffs and are...

While the paper examined the effect of different tax regimes on the Israeli automobile market, the main contribution of this paper is the methodology it employs. As demonstrated, owr framework provides a methodology for examining the effects of changes in tax regimes in differential product...

Using the simple model of Comanor and Frech (1985), I show that vertical mergers and exclusive dealing contracts are not behaviorally equivalent.

We study dynamic price adjustment under imperfect competition when consumers have non-time-separable preferences. In our model an intertemporal link arises in the consumers' maximization problems because current price and firms must take this into account when making their decisions. The main...

In this paper we consider a model of oligopolistic competition where firms make a two-dimensional product line decision. They choose a location in style space, thus, inducing horizontal differentiation, and produce different qualities (a product line) of a given good (vertical differentiation),...
