题目: Consumer Search and Optimal Information

摘要: This paper studies a consumer search model where consumers' valuation of firms' products are uncertain and the consumers only observe a noisy signal about their valuation if they are matched with firms. Firms simultaneously charge prices and consumers sequentially search. Our goal is to characterize those signal structures which maximize consumer surplus. We show that a generalized unit-elastic demand signal structure is consumer-optimal. The optimal generalized unit-elastic demand signal structure always exists and is unique. For binary value distribution, we show that the unique optimal generalized unit-elastic demand signal structure is also the unique optimal signal structure. We explicitly solve the optimal signal structure and provide a closed form solution. We also show that the informativeness of the optimal signal structure is piecewisely monotone with respect to the search cost.
