This paper investigates the role of horizontal and vertical market structures in pricing differentiated products. The conceptual model demonstrates how substitution and complementarity relationships between products and across vertical channels relate to market concentration and market size. The...

This paper investigates the pricing and vertical organization of differentiated products under imperfect competition. In a multiproduct context, we examine how substitution/complementarity relationships among products and vertical structures relate to the exercise of market power. The analysis...

This paper investigates bundle pricing under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschmann index (GHHI)...

This paper investigates the pricing of differentiated products in a vertical sector, with a focus on the role of industry concentration. We propose concentration indices that extend the classical Hirschman-Herfindahl Index (HHI) to include vertical structures that manage differentiated products....

We investigate the survival of new seeds in the US hybrid corn seed market between 2002 and 2007. Controlling geographic location, we find that product characteristics and market structure variables have significant impacts on the hazard of corn hybrids. The results also suggest spill-over...

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...

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...

This paper investigates the pricing of patented traits in the U.S. hybrid corn seed market under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product...

The paper investigates bundle pricing under imperfect competition. In a multiproduct context, the substitution/complementarity relationships among products can affect pricing in complex ways. This is used to motivate multi-product generalizations of the Herfindahl-Hirschmann index, which capture...
