摘要：We analyze a Hotelling location-then-price duopoly game under demand un-certainty with uniformly distributed consumers in a standard quadratic costs sce-nario. The novelty of our approach consists of assuming that rms' beliefs arerepresented by non-extreme-outcome-additive (neo-additive) capacities. We derive rms' subgame-perfect product design decisions under ambiguity. Furthermore, weinvestigate the inuence of ambiguity and ambiguity attitude on equilibrium productdifferentiation and contrast our results with an environment of risky rms. We ndthat the impact of the degree of con dence or ambiguity is particularly signi cantwhen it comes to delivering accurate explanations for a wide range of phenomenarelated to observed product design behavior.
