A Search Model Where Consumers Choose Quantity Based on Expected Price
研究了消费者面临搜索成本时，基于预期价格决定购买数量的价格博弈模型，发现均衡预期价格高于垄断价格，且少量完全知情消费者无法改变这一结果。
I describe a price game in which consumers face search costs and base their quantity decision on the expected price. Because of search costs, the choice of the firm they will buy from is described by a random process. I show that the expected equilibrium price is above the monopoly price. This result does not change if demand comes from a small share of perfectly informed consumers with zero search costs.
