Since the 1970s, there has been mounting empirical evidence that after a certain point, income and happiness, or life satisfaction, are not correlated. However, despite the growing empirical evidence, the new dynamic has not been adequately modeled mathematically. To remedy this gap, in this paper, we go through the literature on the relationship between consumption, income, and happiness and provide a novel mathematical model. As we will see, our model can explain all of the empirical nuances encountered by happiness studies and also helps understand the relationship between reported life-satisfaction and other variables like inequality.

自1970年代以来，越来越多的经验证据表明，在某一点之后，收入和幸福感或生活满意度之间是不相关的。但是，尽管有越来越多的经验证据，但尚未对新的动力学模型进行充分的数学建模。为了弥补这一差距，在本文中，我们浏览了有关消费，收入和幸福之间的关系的文献，并提供了一个新颖的数学模型。就像我们将看到的那样，我们的模型可以解释幸福研究中遇到的所有经验上的细微差别，还可以帮助理解所报告的生活满意度与其他变量（例如不平等）之间的关系。
