Since I do not think that this point is made clear in books or papers, I would like to discuss it in some detail. Consider two economies E1 and E2. The workers in E1 are more cooperative and hard-working. Those in E2 are selfish and lazy. Hence, the labor productivity in the firm in E1 is higher for equally given levels of physical inputs.

The people in E3 are more harmonious and other-regarding within the household. Those in E4 ar
