A Simple Vertical Differentiation Model for Simulating Product Introduction and Preliminary Merger Screening

نویسنده

  • Bruce Lyons
چکیده

The purpose of this model is to examine how the entry of a new product of intermediate quality affects the pricing of existing products, and how it this is changed by alternative ownership patterns. We show how the model’s predictions are consistent with some apparently puzzling consistencies in unregulated pharmaceuticals pricing. We also demonstrate how the model can be calibrated for a quick first filter on the expected consequences of a merger (with or without remedies) between two firms with overlapping product ranges.

Vertical Integration and Competition Policy

Recently, the European Commission has decided to implement a simplified procedure in the context of vertical integration. If the combined market shares of the merging firms are less than 25 percent, upstream and downstream, the Commission will consider the merger harmless. The purpose of this study is to examine the welfare aspects of vertical integration in a simple model and investigate the a...

On vertical mergers and their competitive effects

It is well known that vertical integration can change the pricing incentive of an upstream producer. However, it has not been noticed that vertical integration may also change the pricing incentive of a downstream producer and the incentive of a competitor in choosing input suppliers. I develop an equilibrium theory of vertical merger that incorporates these additional strategic considerations....

Prediction of Nitrogen Injection Performance in Conventional Reservoirs Using the Correlation Developed by the Incorporation of Experimental Design Techniques and Reservoir Simulation

Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous computer processing time. In such cases, a simple statistical model may be a good approach to...

An Analysis of Bundle Pricing in Horizontal and Vertical Markets : The Case of the U . S

In this paper, we investigate substitution/complementarity relationships among products sold with different bundled characteristics and under different vertical arrangements. Our conceptual model demonstrates the interactive price impacts emanating from product differentiation, market concentration and market size. The model is applied to the U.S. cottonseed market using transaction level data ...

A Finite Element Model for Simulating Flow around a Well with Helically Symmetric Perforations

In a perforated well, fluids enter the wellbore through array of perforation tunnels. These perforations are typically distributed in a helical pattern around the wellbore. Available numerical models to simulate production flow into cased-and-perforated vertical wells have complicated boundary conditions or suffer from high computational costs. This paper presents a simple and at the same time ...
