Seasonal Marketing and Timing New Product Introductions
研究提出一种方法，在不改变模型基本假设的前提下，将已知的季节性模式简洁地加入任何动态模型，并展示了该方法如何为新产品引入时机提供战略启示，同时给出了实证应用。
A study shows how to add known seasonal patterns to any dynamic model parsimoniously, and without changing the fundamental model assumptions, illustrates how the method provides strategic implications for timing new product introductions, and provides an empirical application.The study transforms time so that, during high seasons, time is moving faster than normal time.The study also changes the product's growth along its life cycle and suggests that timing introduction decisions are dependent on the shape of the product's life cycle.
