THE IMPACT OF BESTSELLER RANK ON DEMAND: EVIDENCE FROM THE APP MARKET*
利用苹果应用商店前100名应用的日度销售排名数据，研究今日畅销排名对明日需求的因果影响，发现排名第一的应用比未上榜应用消费者愿意多支付约4.5美元，且排名效应在头部递减但前50名仍显著。
This article uses daily data on the ranking by sales of the top 100 apps sold through Apple’s App Store to provide evidence of the causal impact of today’s bestseller rank information on tomorrow’s demand. The estimates indicate that the willingness to pay of consumers is about $4.50 greater for a top ranked app than for the same unranked app. The results also indicate that the effects of bestseller status on willingness to pay decline steeply with rank at the top ranks, but remain economically significant for the apps in the first half of the top 100 list.
