Monopoly Quality Degradation and Regulation in Cable Television
基于Mussa-Rosen垄断质量选择模型，计算有线电视市场质量降级程度及监管影响，发现质量降级下限为11%至45%，受监管市场质量更高、降级更少。
Using an empirical framework based on the Mussa‐Rosen model of monopoly quality choice, we calculate the degree of quality degradation in cable television markets and the impact of regulation on those choices. We find lower bounds of quality degradation ranging from 11 to 45 percent of offered service qualities. Furthermore, cable operators in markets with local regulatory oversight offer significantly higher quality, less degradation, and greater quality per dollar, despite higher prices.
