Understanding the way in which knowledge is technically produced and transferred, and how its diffusion path can be characterized is of fundamental importance for the performance of an economy. Although this fact seems to be plausible ex ante, the relevant literature so far has paid less...

A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

In this paper we develop a general model of one-sided and two-sided platform businesses and apply it to a monopolist framework. We have a particular interest in how the social loss and other metrics depend on the strength of the network (direct or indirect) effect. We study how network effects...

The static model of two sided markets proposed by Rochet and Tirole analyses optimal pricing of a monopolistic platform at the equilibrium point. Their framework implicitly assumes that for each prices set by the platform, the equilibrium number of users on each side will be unique. However,...

In this paper we apply a general model of one-sided and two-sided platform businesses to a collusive framework which we model as joint profit maximization. We have a particular interest in how the social loss and other metrics depend on the strength of the network (direct or indirect) effect. We...

This paper proposes methods for identifying indirect network effects with dynamically optimizing consumers purchasing a durable hardware good and associated software. We apply this model to a data drawn from the DVD player and titles markets. We observe model-level prices, sales and...

This paper measures the impact of vertically integrated and exclusive software on industry structure and welfare in the sixth-generation of the U.S. videogame industry (2000-2005). I specify and estimate a dynamic model of both consumer demand for hardware and software products, and software...
