討論提要

Allow quality variation in a duopoly of locationally differentiated products a-la-Hotelling (1929); analyze the impact of quality variations on the choices of the varieties produced.

結論

(1) Contrary to the intuition of the ‘principle of minimum differentiation’, firms prefer to maximally differentiate their products in the variety space so that they can achieve higher levels of quality, price and profits.

(2) It is striking to see that the simple addition of quality as a strategic variable to the classic model of variety differentiation leads to maximal differentiation, a result directly opposite to the ‘Principle of Minimum Differentiation’

延伸研究

Consider the effect of “variety cost of product” on location and quality choices.
