Estimating Production Functions of Multiproduct Firms
针对多产品企业缺乏产品层面投入分配数据的问题，提出利用产品价格和产出需求来估计产品层面投入分配和生产函数的策略，对研究多产品企业生产行为的经济学者有用。
Abstract Multiproduct firms constitute a considerable share of firms and account for an even greater share of production. Nevertheless, the vast majority of production function estimates are based on the assumption that firms are single-product manufacturers. This assumption is due to a lack of data on how firms allocate their inputs across their various product lines. I provide a strategy for estimating product-specific input allocations and production functions of multiproduct firms involved in monopolistic competition. The strategy is based on using firms’ product prices and output demand in solving for product-level input allocations.
