在最近的一篇文章中，斯特鲁普和吉夫特试图“证明在南越稻米生产中观察到的劳动力边际产出实际上为零”（第417页）。[1]他们为支持这一结论而引用的数据是与零没有显著差异的生产函数劳动系数。[2]然而，我们认为斯特鲁普和吉夫特的结论是没有根据的，原因有二。首先，他们只使用家庭劳动而不是全部劳动投入。也就是说，他们排除了所有雇佣劳动。其次，他们对家庭劳动投入的衡量实际上是家庭水稻劳动加上家庭副作物劳动的总和，而不是仅仅是水稻劳动。这两种规格都可能
In a recent article for this journal, Stroup and Gift attempt "to show that the observed marginal product of labor in South Vietnamese rice production is virtually zero" (p. 417).1 The data they adduce to support this conclusion are production-function labor coefficients that are not significantly different from zero.2 However, we believe Stroup and Gift's conclusions are unwarranted for two reasons. In the first place, they have used only familylabor instead of total-labor input. That is, they have excluded all hired labor. In the second place, their measure of family-labor input is actually the sum of family labor on rice plus family labor on secondary crops, instead of only rice labor. Either of these specifications might have made
