虽然离散选择模型很好地描述了差异化商品的需求结构，但在其应用中仍有两个重要问题尚未解决。首先，对选择集的总需求是外生固定的。第二，多个类别的商品不能无限制地处理。在本文中，我们通过建立一个与离散选择模型一致的完全效用最大化问题来解决这些缺陷，并推导出对应用研究的启示。然后，我们将结果应用于番茄酱和蛋黄酱市场，并调查因考虑多个类别的商品而产生的差异。
Although discrete choice models are well suited to describing the demand structure of differentiated goods, two important problems remain unsolved in their application. First, the total demand for a choice set is exogenously fixed. Second, multiple categories of goods cannot be handled in an unrestrictive way. In this paper, we address these flaws by formulating a complete utility maximization problem that is consistent with discrete choice models and derive the implications for applied research. We then apply the results to the ketchup and mayonnaise markets and investigate the differences arising from the consideration of multiple categories of goods.
