The Impact of Product Differentiation on Symmetric R&D Networks

Alghamdi, Mohamad . 2020

This paper examines the impact of product differentiation on an R&D network. We find that when firms produce goods that are complements or independent, R&D expenditure, prices, firms’ net profits and total welfare are always higher under price competition than under quantity competition. When goods are substitutes, R&D expenditure and profits are higher under quantity competition than under price competition. Also, when goods are substitutes and products are sufficiently differentiated, then total welfare is higher in the Bertrand equilibrium than under the Cournot equilibrium. Beyond this threshold level of product differentiation, Cournot competition is superior in terms of social welfare. The paper finds that the key threshold level of product differentiation, determining the relative superiority of the Cournot and Bertrand equilibrium when goods are substitutes, depends on the cost efficiency of R&D and the number of collaborative partnerships that firms are participate, relative to the size of the network. We show that when goods are substitutes, if the network is dense so that the number of partnerships is large relative to the number of firms operating in the market, then the threshold value of the product differentiation parameter can be small.
