On the Formal Theory of Inspection and Evaluation in Product Markets
构建了消费者在不完全信息下的行为形式理论，商品由多个可观察性不同的特征描述，消费者最优策略涉及检查（抽样观察一般特征）和评估（消费观察具体特征），并分析了比较静态。
This paper builds a formal theory of consumer behavior under imperfect information when goods are described by multiple characteristics which vary in their degree of "ob servability."An optimal strategy for the consumer is shown to exist.In general, this strategy is shown to involve both inspection (sampling to observe general characteristics of goods) and evaluation (consumption of goods to observe specific characteristics) .Comparative statics of the optimal strategy are.also analyzed
