英文摘要：
Economic competition between humans leads to income inequality, but, so far, there has been little understanding of underlying quantitative mechanisms governing such a collective behavior. We analyze datasets of household income from 67 countries, ranging from Europe to Latin America, North America and Asia. For all of the countries, we find a surprisingly uniform rule: Income distribution for the great majority of populations (low and middle income classes) follows an exponential law. To explain this empirical observation, we propose a theoretical model within the standard framework of modern economics and show that free competition and Rawls\' fairness are the underlying mechanisms producing the exponential pattern. The free parameters of the exponential distribution in our model have an explicit economic interpretation and direct relevance to policy measures intended to alleviate income inequality.

中文摘要：
人类之间的经济竞争导致收入不平等，但到目前为止，人们对支配这种集体行为的潜在数量机制知之甚少。我们分析了67个国家（从欧洲到拉丁美洲、北美和亚洲）的家庭收入数据集。对于所有国家，我们都发现了一个惊人的统一规则：绝大多数人口（中低收入阶层）的收入分配遵循指数规律。为了解释这一实证观察，我们在现代经济学的标准框架内提出了一个理论模型，并表明自由竞争和罗尔斯的公平是产生指数模式的潜在机制。我们模型中指数分布的自由参数具有明确的经济解释，并与旨在缓解收入不平等的政策措施直接相关。
