Licensors of patents essential to a standard are often required to license on reasonable and non-discriminatory (RAND) terms. Using a model with owners of essential patents and licensees who invest into standard-conforming technologies, this paper demonstrates that the non-discriminatory...

Whether input suppliers charge customized (discriminatory) or industry-wide (uniform) prices affects downstream manufacturers' incentives to innovate. This paper investigates the implications of input price discrimination when an upstream monopolist commits to prices before downstream firms make...

This paper studies third degree price discrimination in a monopolistically competitive market. When the number of firms is fixed, price discrimination raises firm profit and reduces consumer welfare relative to uniform pricing. In the long run, the equilibrium product variety under price...

This paper studies the welfare effects of location space constraints when the duopoly sellers are vertically separated. As the downstream firms respond to higher input prices by locating further away from the center of the market, constraining them to locate within the linear city allows the...

This paper studies differential pricing by an upstream monopolist whose cost to supply the intermediate good differs across buyers in the downstream. It is shown that, different from third degree price discrimination based on the downstream firms' cost of transforming the intermediate good into...

This paper considers an entry game in which an incumbent firm operates in a number of markets and a potential entrant seeks to enter some or all of the markets. While price discrimination has usually been thought of as a barrier to entry, in our model it is not and, on the contrary, we find that...

Antitrust laws in many countries prohibit the setting of differential prices across buyers who compete against each other. In this paper, we consider a setting in which a downstream manufacturer holds non-controlling stakes in its rival and both buy input from an unptream monopolist. We find...
