Abstract: | Abstract. We present a model of equilibrium price dispersion in which a per-unit subsidy to buyers can reduce average prices. The reason is that subsidies have two effects on average prices that work in opposite directions. First, subsidies raise buyers' willingness-to-pay, and by itself this causes firms to charge higher prices. However, since a higher willingness-to-pay lowers the relative cost of search, subsidies also induce more search. This creates a second effect that puts pressure on firms to reduce prices. We show that the second effect can dominate, thus causing an overall reduction in average price. |
