Who Benefits from Information Disclosure? The Case of Retail Gasoline
研究了在线价格信息披露对竞争的影响，发现披露使平均利润率提高9%，但在高搜索区域（收入较高）利润率增加最少甚至下降，表明信息披露可能产生重要的分配效应。
How does online price disclosure affect competition when both consumers and firms can use the disclosed information? This paper addresses this question exploiting the sequential implementation of an online price-disclosure policy in the Chilean retail gasoline industry. The results show that disclosure increased margins by 9 percent on average, though the effects varied across the country depending on the intensity of local search behavior. Because margins increased the least, and even decreased, in high-search areas, where income is also higher, the results also show that price disclosure policies may have important distributional effects.
