We study how changes in market structure affect how firms engage in second-degree price discrimination. Specifically, we study how a large incumbent cable firm changes its menu of price-quality offerings and mixed bundles in response to entry. Competition strongly decreases the rate at which prices increase in quality and induces the incumbent to introduce additional medium- to high-quality offerings that the incumbent could have introduced absent competition but chose not to. Our findings are relevant for the broadband industry because they suggest that competition can improve broadband quality through direct pricing effects without any changes in investment in maximum quality.

捆绑销售：竞争对二级价格歧视的影响

我们研究市场结构的变化如何影响企业如何参与二级价格歧视。具体来说，我们研究了一家大型现有有线电视公司如何根据进入改变其价格质量产品和混合捆绑的菜单。竞争极大地降低了质量价格上涨的速度，并促使现有企业推出额外的中到高质量产品，而现有企业本可以在没有竞争的情况下引入但选择不这样做。我们的研究结果与宽带行业相关，因为它们表明竞争可以通过直接定价效应提高宽带质量，而无需改变对最高质量的投资。
