About the Event
Fierce competition has been blamed as the engine behind product proliferation and the complexity that proliferation brings. Product proliferation has been blamed for widespread productivity losses in manufacturing. In this presentation we will summarize results from different work but will give special attention to insights from two sources using game theory models (modelling horizontal and vertical competition). In the vertical competition model we analyse different scenarios depending on which member has the first-mover advantage in terms of pricing and on which member has the power to determine the number of product variants that are put on sale. The objective of this work is to study the interaction between pricing and assortment strategies and to investigate how the power structure affects these decisions in a supply chain. In the horizontal competition model we consider how the number of product variants compares with that of a monopolist.
