Aggregation of Price Risk over Commodities: An Economic Index Number Approach
将指数数的经济理论扩展到生产中商品价格风险的加总，提出加总价格风险的超指数，并与Tornqvist和Fisher型产出数量指数关联，以曼尼托巴省主要作物为例展示其实证重要性。
Abstract This article extends the economic theory of index numbers to the aggregation of price risk over commodities in production. Superlative indexes of aggregate price risk are related to Tornqvist and Fisher—type output quantity indexes. An application to major crops in Manitoba illustrates the empirical importance of the analysis.
