Hotelling's Location Model with Quality Choice in Mixed Duopoly
We investigate a mixed duopoly market by introducing quality choice into the Hotelling-type spatial competition model with linear transportation costs. We show that there does not exist a subgame perfect Nash equilibrium (SPNE) of location choice in the three-stage game that is location-then-quality choice and subsequent price choice. Moreover, we show the conditions of the existence of the quality equilibrium.
