The Short-Run Aggregate Profit Function and the Capacity Distribution
分析了生产活动的产能分布与短期总利润函数之间的映射关系，证明了在两种投入情况下该映射是一一对应的，并给出了短期总利润、产出供给和投入需求函数的近似多项式形式。
The mapping between the capacity distribution of production activities and the short-run aggregate profit function is analyzed, with emphasis on the recovery of the former from the latter and the characterization of the profit function. For the case of two inputs, it is shown that the mapping is one-to-one. It is also shown that the short-run aggregate profit and, hence, the output supply and input demand functions can be approximated by polynomials in the reciprocals of normalized input prices. Properties of these functions are also presented. Copyright 1994 by The editors of the Scandinavian Journal of Economics.
