耐用品营销对旧型号有淘汰效应。我考虑两种情况：承诺（在第一阶段决定在营销上投资多少）和不承诺（在第二阶段决定）。我关注的事实是，引入更高质量的模型会降低使用旧模型的消费者的效用。我表明，在这两种情况下，市场营销的均衡水平高于社会最优水平。问题的关键在于，更大的过时效应促进了替代需求，驱使垄断者花费超过社会最优水平。
Durable-goods marketing has an obsolescence effect on older models. I consider two cases: commitment (where the decision on how much to invest in marketing is made in the first period) and noncommitment (where the decision is made in the second period). I focus on the fact that the introduction of a higher quality model lowers the utility of consumers using an older model. I show that, in both cases, the equilibrium level of marketing rises above the socially optimal level. The point is that a larger obsolescence effect promotes replacement demand, driving the monopolist to spend more than is socially optimal.
