Subjective Well-Being and Income: Is There Any Evidence of Satiation?
研究检验了收入超过基本需求后是否不再提升主观幸福感，发现两者关系近似对数线性，未发现满足点。
Many scholars have argued that once “basic needs” have been met, further rises in income are not associated with further increases in subjective well-being. We assess the validity of this claim in comparisons of both rich and poor countries, and also of rich and poor people within a country. Analyzing multiple datasets, multiple definitions of “basic needs” and multiple questions about well-being, we find no support for this claim. The relationship between well-being and income is roughly log-linear and does not diminish as incomes rise. If there is a satiation point, we are yet to reach it.
