Taxes and Subsidies in the Input-Output Model
重新审视了Metzler关于里昂惕夫系统中税收和补贴对竞争性供给价格影响的分析，证明其结论在放宽假设后仍成立，并指出Allen关于从价税的结论有误，同时给出了Metzler矩阵的定理及其逆矩阵的有用性质。
This paper reexamines Metzler's analysis of the effects of taxes and subsidies on the competitive supply prices of output in Leontiefs system. It will be shown that Metzler's conclusions are valid even if one removes the assumptions made by Metzler, and that Allen's conclusion concerning the ad valorem tax is false. We present some interesting properties of Leontiefs system, and also provide a theorem on Metzler's matrix, proving it and deriving some useful properties on the inverse matrix of the input-output model
