Testing a Theory of Exact Aggregation
检验了Jorgenson等人(1982)的精确加总限制在消费者行为模型中的重要性，发现数据强烈拒绝该限制，而按人口特征分层是更好的建模策略。
This paper assesses the importance of exact aggregation restrictions in the context of Jorgenson, Lau and Stoker's (1982) model of aggregate consumer behaviour, and analyzes demographic variables. We find the exact aggregation restrictions are strongly rejected by the data, and stratification of observations by demographic characteristics is a superior modelling strategy.
