A Note on the Use of the Cobb‐Douglas Profit Function
指出柯布-道格拉斯利润函数存在内在刚性,常被误读为实证发现,因此提醒研究者谨慎使用,并详细阐述了该函数的特性与证明。
Abstract Factor demand and output supply functions formulated within the framework of the Cobb‐Douglas profit function have been widely used for the study of technological and production behavior of the farm firm. There are certain inbuilt rigidities in this function that have been very often construed as empirical findings by various authors. As such, a note of caution in the use of this function was thought necessary. An attempt is made to spell out the characteristics of this function with proofs.
