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
Agriculture like all other trades, and particularly in a commercial country, is subject to a re-action, which, in an opposite direction, succeeds the action of a strong stimulus. Thus, when war interrupts the importation of corn, its consequent high price attracts capital to the land, from the large profits which such an employment of it affords; this will probably cause more capital to be employed, and more raw produce to be brought to market than the demands of the country require. In such case, the price of corn will fall from the effects of a glut, and much agricultural distress will be produced, till the average supply is brought to a level with the average demand.

白话
农业像其他行业一样,尤其在有商业的国家,强刺激之后会有反向反应。战争中断粮食进口,粮价高涨,高利润吸引资本涌入农业,结果生产超过需求,粮价因过剩下跌,农业陷入困境,直到平均供给和平均需求重新平衡。核心是:农业投资会过度反应,形成周期。今天农业政策要警惕一哄而上,建立预警和调整机制,避免“价高伤农、价低也伤农”的循环。

你所在的行业,是否也容易在强刺激后出现过度投资和随后的萧条?
