THE SUPPLY‐DRIVEN INPUT‐OUTPUT MODEL: A NEW INTERPRETATION BUT STILL IMPLAUSIBLE
反驳了Gruver提出的供给模型生产函数理论基础,认为其仅在极特殊情况下成立;同时论证小投入系数变化不足以作为使用供给模型进行影响研究的理由,并指出不同方法得出的就业估计差异很大。
ABSTRACT. In this reply, I argue that the production function proposed by Gruver provides a theoretical foundation for the supply model only in a most trivial case. He proposes a more general alternative which is, however, still very implausible. Furthermore, against Rose and Allison, I argue that small input‐coefficient changes provide an insufficient excuse for using the supply model for impact studies, and I show that employment estimates may be quite different depending on the approach used.
