Última On Pricing and Vertical Organization of Differentiated Products: The Case of Soybean Seed Industry AgEcon Shi, Guanming; Chavas, Jean-Paul. This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, a Cournot model is used to examine how substitution/complementarity relationships among products and vertical structures can affect the exercise of market power. This motivates a generalization of the Herfindahl-Hirschman index (termed VHHI) capturing how market concentration and vertical structures interact to influence prices of differentiated products. The analysis is applied to pricing of soybean seeds in the US over the period 2000-2007. The analysis considers two vertical structures employed by biotech firms: vertical integration and licensing. The econometric analysis finds evidence that vertical...

Ano: 2009 URL: http://purl.umn.edu/49186 The Effects of Vertical Organization on the Pricing of Differentiated Products AgEcon Shi, Guanming; Chavas, Jean-Paul. We investigate differentiated product pricing and the effects of vertical organization under imperfect competition. We rely on vertical measures of concentration (termed VHHI) to study how the exercise of market power varies with substitution/complementarity relationships among products and vertical structures. This approach is applied to U.S. soybean seed pricing under vertical integration versus licensing. We find evidence that vertical organization affects seed prices, with an impact ranging from 1.87% to 13.6% of the mean price. These effects vary by institutional setup.We also find that complementarity can mitigate price enhancements associated with market concentration.
