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 new settlements, where the arts and knowledge of countries far advanced in refinement are introduced, it is probable that capital has a tendency to increase faster than mankind: and if the deficiency of labourers were not supplied by more populous countries, this tendency would very much raise the price of labour. In proportion as these countries become populous, and land of a worse quality is taken into cultivation, the tendency to an increase of capital diminishes; for the surplus produce remaining, after satisfying the wants of the existing population, must necessarily be in proportion to the facility of production, viz. to the smaller number of persons employed in production. Although, then, it is probable, that under the most favourable circumstances, the power of production is still greater than that of population, it will not long continue so; for the land being limited in quantity, and differing in quality; with every increased portion of capital employed on it, there will be a decreased rate of production, whilst the power of population continues always the same.

白话

在新殖民地,先进技艺和知识被引入,资本往往比人口增长更快;若没有人口稠密国家补充劳动力,工资会被推得很高。但随着人口增多、劣质土地被耕种,资本增长势头减弱,因为剩余产出取决于生产便利程度,即更少人生产。尽管最有利条件下生产力仍大于人口力,但土地有限且质量递减,每增加一份资本,产出率下降,而人口力不变。所以增长终会放缓。

李嘉图分析新殖民地资本增长快于人口,但土地有限导致收益递减,增长势头最终减弱。
