Network Competition and the Timing of Commercials
研究少数电视台竞争时，广告插播时机的选择如何影响观众数量。通过理论模型和美国四大电视网的数据分析，发现均衡时所有电视台会同时播放广告，但随着节目进行协调程度下降。
In a market with a small number of networks, the timing of the commercial breaks is a very important factor in determining the number of viewers facing a channel. Using a theoretical model and statistical analysis with empirical data from the four networks in the United States, we analyze the equilibrium achieved in this network monopolistic competition. Among other things, it is shown theoretically and empirically that in equilibrium all networks broadcast commercial breaks at the same time. As the ability to coordinate is not always possible, it is shown that, as the program progresses, the level of coordination decreases.
