We investigate pricing and demand issues for four fresh potato categories (russet, red, white, and minor colored), organic fresh potatoes, and two processed potato categories (frozen/refrigerated and dehydrated) using a nonlinear generalized almost ideal demand system (GAIDS) that is closed...

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 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)...
