Experimentation and Learning in a Differentiated-Products Duopoly
研究双寡头企业不确定产品差异化程度时的定价行为，企业通过需求差异学习，价格差异越大信息越多；替代性高时价格离散加剧，差异化高时价格压缩。
This paper explores price-setting behavior in the context of a duopoly in which firms are uncertain about the degree of product differentiation. Firms learn from the difference in their realized demands in light of the price differential. The informativeness of this market experiment is shown to be increasing in size of the price differential. In markets with highly substitutable products, price dispersion is enhanced as firms adjust their prices so as to generate more information. In markets with highly differentiated products, firms compress their prices as they prefer to reveal less about the extent of product differentiation.
