Why the Rich Are Nastier Than the Poor – A Note on the Distribution of Wealth When Individuals Care for Payoff Differentials
研究了当个体通过损害他人来提升相对地位时，最优投资随自身财富增加而增加、随他人财富增加而减少，解释了富人为何更可能采取损害行为。
In view of empirical and evolutionary findings on the relevance of relative payoffs we study--as a benchmark case--a model in which individuals maximize payoff differentials having the opportunity to invest in their relative standing by harming others. Interestingly, optimal investments are increasing in individuals' own wealth and decreasing in the wealth of others. Copyright 2000 by WWZ and Helbing & Lichtenhahn Verlag AG
