THE CHARITY OF THE EXTREMELY WEALTHY
研究发现白手起家的亿万富翁比继承财富的亿万富翁更可能签署捐赠誓言、进入大额捐赠榜单，且捐款更多，并探讨了财富来源与慈善行为关联的可能解释。
In this article, we show that, compared to billionaires who have inherited their wealth, billionaires who have made their own wealth are more likely to sign the Giving Pledge and more likely to be in the Million Dollar Gifts list or the Philanthropy Top 50 list of big givers. If they give, self‐made billionaires also tend to donate more money. We explore several possible explanations for this correlation between the origin of billionaires' wealth and their charitable giving, and present evidence that suggests that self‐made billionaires tend to spend more money, both by giving money away and by buying expensive items.
