报告摘要：

We develop a model in which consumers search experts to obtain recommendations and prices to treat a problem, while experts may “cheat” by recommending an unnecessary treatment.  We characterize the optimal sequential search strategy by consumers with a positive search cost, and show that consumer search and expert behavior interact in rich and---at times---surprising ways. In equilibrium, all experts behave honestly if search cost is sufficiently low, but cheating occurs with positive probabilities otherwise. In the latter case, an increase in search cost can actually reduce expert cheating, yielding a higher search benefit that restores optimal consumer search under the higher search cost and also leads to lower prices.
