A BOX–COX CONSUMER DEMAND SYSTEM NESTING THE ALMOST IDEAL MODEL*
提出一种基于Box-Cox变换的广义消费者需求系统，比几乎理想需求系统等现有模型能更灵活地响应价格和支出变化，且形式简单易用。用日本非耐用品数据验证，新模型在解释力和弹性合理性上优于嵌套模型。
This article proposes a consumer demand system that has a generalized functional form characterized by the Box–Cox transformation. The new model offers a wider range of responses to both price and expenditure changes than the existing price independent generalized linear models, including the almost ideal demand system. Even with these features, its functional form is relatively simple and easy to interpret and implement. An empirical illustration is given for Japanese demand for nondurable goods and services. The results show that the new model is preferable to the nested models in terms of relative explanatory power and producing reasonable elasticities.
