摘要

A firm may decide to make total-surplus-reducing purchase recommendations in response to consumer heterogeneity in an experience good setting with endogenous prices. First, we show under which conditions the firm chooses to make such biased recommendations in a monopoly setting. Second, we propose a duopoly model with differentiated products in which single-product firms compete in uniform prices and recommendation policies. We establish when and why both firms bias their recommendations. This bias can disappear when the market becomes less competitive, one firm exits, or both firms merge.

中文摘要

在体验品市场中,面对内生价格与消费者异质性,企业可能选择做出降低总剩余的购买推荐。首先,我们展示了在垄断情境下,企业选择做出此类有偏推荐的条件。其次,我们提出一个差异化产品的双寡头模型,其中单一产品企业在统一定价和推荐策略下竞争。我们确定了双方企业何时以及为何会偏向其推荐。当市场竞争减弱、一家企业退出或两家企业合并时,这种偏差可能消失。
