The striking thing about the happiness-income paradox is that over the long-term--usually a period of 10 y or more--happiness does not increase as a country's income rises. Heretofore the evidence for this was limited to developed countries. This article presents evidence that the long term nil relationship between happiness and income holds also for a number of developing countries, the eastern European countries transitioning from socialism to capitalism, and an even wider sample of developed countries than previously studied. It also finds that in the short-term in all three groups of countries, happiness and income go together, i.e., happiness tends to fall in economic contractions and rise in expansions. Recent critiques of the paradox, claiming the time series relationship between happiness and income is positive, are the result either of a statistical artifact or a confusion of the short-term relationship with the long-term one.
幸福-收入悖论引人注目的一点是,从长期来看——通常是 10 年或更长时间——随着一个国家收入的增长,幸福感并不会提高。迄今为止,这方面的证据仅限于发达国家。本文提供的证据表明,幸福感与收入之间的这种长期零关系也适用于一些发展中国家、从社会主义向资本主义过渡的东欧国家,以及比之前研究中更为广泛的发达国家样本。它还发现,在这三组国家中,短期幸福感和收入是相关的,即幸福感在经济收缩时下降,在经济扩张时上升。最近对悖论的批评声称,幸福感和收入之间的时间序列关系是正相关的,这要么是由于统计上的人为因素,要么是由于将短期关系与长期关系混淆。
