题目:  Influencer as Selector of Good Deals

摘要：In a consumer search model with experience goods and both horizontal and vertical product differentiation, we study the impacts of an influencer whose primary function is to select good deals for its followers. We establish conditions under which an influencer is viable and show that its presence in general benefits consumers but hurts firms as a whole. We also examine how changes in various market conditions affect the prospect of influencer marketing. Finally, we endogenize firms' quality choices and study how the presence of an influencer affects firms' incentives to invest in quality.
