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
In the natural advance of society, the wages of labour will have a tendency to fall, as far as they are regulated by supply and demand; for the supply of labourers will continue to increase at the same rate, whilst the demand for them will increase at a slower rate. If, for instance, wages were regulated by a yearly increase of capital, at the rate of 2 per cent., they would fall when it accumulated only at the rate of 1-1/2 per cent. They would fall still lower when it increased only at the rate of 1, or 1/2 per cent., and would continue to do so until the capital became stationary, when wages also would become stationary, and be only sufficient to keep up the numbers of the actual population. I say that, under these circumstances, wages would fall, if they were regulated only by the supply and demand of labourers; but we must not forget, that wages are also regulated by the prices of the commodities on which they are expended.

白话
社会自然发展时，若工资只由劳动力供求决定，劳动供给持续增加而需求增加较慢，工资便有下降趋势。例如资本年增2%时工资可维持，若只增1.5%工资就降，增1%或0.5%降得更低，直到资本停滞，工资仅够维持现有人口。但工资还受其所购商品价格调节，不能只看供求。所以，判断工资走势要同时看劳动供求和物价，不能单看资本增长。
上下文
李嘉图在《政治经济学及赋税原理》中分析工资规律，提出工资受劳动供求与商品价格双重调节。
今日一问
你评估收入前景时，是否只盯着岗位供求，而忽略了物价与资本增速的变化？
