【主题】Endogenous Horizontal Product Differentiation in a Mixed Duopoly
【摘要】This paper aims to study the strategic role of a welfare-maximizing public firm in a horizontal product differentiation model under both Bertrand and
Cournot competition. We find that (i) the mixed homogeneous goods market arises under Bertrand firms when the product differentiation is very costly, but it is
impossible under Cournot competition because the private obtains no incentives to produce homogeneous products with the public firm; (ii) when the investment is very effective, the public firm always takes the responsibility to undertake the differentiation investment under both Bertrand and Cournot, while the private firm
responds to be a free-rider and enjoys the benefits from resulting product differentiation; (iii) Bertrand firms produce heterogeneous products in a wider range
of parameter values compared to Cournot firms. However, when products are differentiated under both modes, Cournot competition leads to a higher degree of
product differentiation. We also apply our model into international trade to see the effect of endogenous horizontal product differentiation on trade patterns.
