Competing to Sell the Reference Product

In a sequential model of vertical product differentiation in which consumers are loss-averse, I analyse how firms compete to sell the reference product when they set prices. I find that there are two subgame perfect equilibria: one where the reference point for all consumers is the higher-quality product; and the other where the reference point is the lower-quality product. However, applying the risk-dominance criterion, I obtain that the sole risk-dominant equilibrium is for the higher-quality firm to sell the reference product. Since the hedonic price of the higher-quality product is the highest, consumers do not suffer any psychological disutility in the risk-dominant equilibrium.
