Injecting money might improve the living standards in the villages receiving the funds, but doing so may well drive up the cost of food throughout the country, causing residents of non-subsidized villages to fall into poverty.

其次，必须认识到经济体是复杂并且相互联系的。比如，考虑一项政府政策，其中的补贴以印钞为资金来源，对象为1,000个村庄的村民。对整体经济来说，这未必是件好事。注入资金可能会改善获得补贴的村庄的生活水平，但也会大大推高整个国家的食品成本，导致无补贴村庄的村民陷入贫困。微观干预的宏观经济影响是贫困之所以持续的一个重要原因，尽管干预的初衷是对抗贫困。
