大卫·李嘉图《政治经济学及赋税原理》· On the Principles of Political Economy and Taxation · 投资
Will not this principle account for the different effects, which it was remarked were produced on the prices of commodities, from the altered value of money during the Bank-restriction? It was objected to those who contended that the currency was at that period depreciated, from the too great abundance of the paper circulation, that, if that were the fact, all commodities ought to have risen in the same proportion; but it was found that many had varied considerably more than others, and thence it was inferred that the rise of prices was owing to something affecting the value of commodities, and not to any alteration in the value of the currency. It appears however, as we have just seen, that in a country where commodities are taxed, they will not all vary in price in the same proportion, either in consequence of a rise or of a fall in the value of currency.

白话
这个原理能否解释银行限制时期货币价值变动对商品价格产生的不同影响？当时有人反驳说，如果纸币过多导致货币贬值，所有商品应该同比例上涨；但发现许多商品涨幅差别很大，于是推断是商品本身价值变了，而非货币价值变了。然而，正如我们刚看到的，在商品被征税的国家，由于货币价值升降，商品价格不会同比例变动。

李嘉图回应银行限制时期关于货币贬值的争论，用赋税原理解释价格不同比例变动。
今日一问
当物价普遍上涨但涨幅不一时，你如何判断是货币贬值还是商品本身变化？
