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

If the gold mine from which money was obtained were in the same country, in that case, after the rise of wages, 210_l._ might be necessary to be employed, as capital, to obtain the same quantity of metal that 200_l._ obtained before: for the same reason that the hunter and fisherman required 10_l._ in addition to their capitals, the miner would require an equal addition to his. No greater quantity of labour would be required in any of these occupations, but it would be paid for at a higher price, and the same reasons which should make the hunter and fisherman endeavour to raise the value of their game and fish, would cause the owner of the mine to raise the value of his gold. This inducement acting with the same force on all these three occupations, and the relative situation of those engaged in them being the same before and after the rise of wages, the relative value of game, fish, and gold, would continue unaltered. Wages might rise twenty per cent., and profits consequently fall in a greater or less proportion, without occasioning the least alteration in the relative value of these commodities.

白话

如果金矿和渔猎在同一国家,工资上涨后,矿主也需要多投入10镑资本才能获得同样多的金属,就像猎人和渔夫各需多投入10镑一样。所需劳动量没变,但劳动价格提高了,所以三者都有动力提高自己产品的价值。由于这种动力对三者作用相同,且它们的相对处境在工资上涨前后一样,所以猎物、鱼和金的相对价值保持不变。工资涨20%,利润相应下降,但商品比价不受影响。

上下文

李嘉图假设金矿与渔猎同处一国,说明工资普遍上涨不影响相对价值。

今日一问

如果所有行业成本同步上升,产品比价会变吗?这对你理解通胀有何启发?
