Estimation of multi-output production functions with incomplete data: A generalised maximum entropy approach
提出一种基于信息理论的方法，仅利用生产数据即可估计多产出多要素企业的生产函数，无需活动特定投入分配或价格数据，适用于病态问题，模拟数据表现良好。
One problem commonly encountered when analysing multiproduct-multifactor firms is the lack of activity-specific input data. The present study contributes to the empirical literature on production functions by presenting an information theoretic approach to estimating production functions in the absence of activity-specific input allocations. The procedure relies solely on production data, so that behavioural hypotheses (e.g., profit maximisation) are not required and estimation can proceed in the absence of price data. In addition, the method can be applied to ill-posed problems. The proposed procedure is demonstrated with simulated production data and exhibits favourable statistical properties.
