Financial Innovation and Divisia Monetary Aggregates: Comment on Ford, Peng, Mullineux (1992)
指出Ford等人(1992)论文中的数学论证错误，并证明即使存在非中性技术变革，基于机会成本的加权体系仍然适用。
This note shows that there is an error in the mathematical argument deployed by Ford et al . (1992). Once this is corrected, we see that, remarkably, the standard opportunity cost based weighting system remains appropriate even in the face of non‐neutral technical change .
