The Impact of the 1992 Cable Act on Household Demand and Welfare
评估1992年《有线电视法》对家庭福利的影响，发现法规虽强制降价10-17%，但系统策略性反应导致家庭福利未变，价格变化是主因。
I measure the benefit to households of the 1992 Cable Act in light of strategic responses by cable systems to the regulations mandated by the act. A discrete-choice differentiatedproduct model of household demand for all offered cable television services forms the basis of the analysis. Aggregation over households and service combinations to the level of the data permits estimation on a cross-section of cable markets from before and after the act. The results indicate that while the regulations mandated price reductions of 10‐17% for cable services, observed system responses yielded no change in household welfare. Post-act changes in cable prices are responsible for most of the difference.
