利润函数的蒙特卡罗模拟表明，灵活的功能形式可以排名几乎相同的艾伦-Uzawa部分替代弹性或价格和固定因素弹性。灵活的函数形式近似的产出价格弹性通常比近似的投入价格或固定要素弹性。Minflex Laurent函数形式并没有表现出比translog和广义Leontief对应形式更好地近似潜在的弹性。
Monte Carlo simulations of profit functions indicate that flexible functional forms may be ranked nearly the same with respect to Allen-Uzawa partial substitution elasticities or price and fixed factor elasticities. Flexible functional form approximations of output price elasticities are generally worse than approximations of input price or fixed factor elasticities. Minflex Laurent functional forms did not appear to approximate underlying elasticities any better than did their translog and generalized Leontief counterparts.
