每周商店级数据的市场份额模型是有用的，以了解竞争结构，提供自己的和交叉价格弹性。然而，这些模型不能用来检查在特定的时间段内哪些品牌的市场份额会被哪些品牌夺走。正是出于这一目的，我们提出了一个新的模式，它确实允许这样的检查。我们说明了两个产品类别在两个市场的模型，我们提供的份额转换估计。我们还演示了如何使用我们的模型来分解自身和交叉价格弹性。
Market share models for weekly store-level data are useful to understand competitive structures by delivering own and cross price elasticities. These models can however not be used to examine which brands lose share to which brands during a specific period of time. It is for this purpose that we propose a new model, which does allow for such an examination. We illustrate the model for two product categories in two markets, and we provide share-switching estimates. We also demonstrate how our model can be used to decompose own and cross price elasticities.
