英文摘要：
  Growing economic inequalities are observed in several countries throughout the world. Following Pareto, the power-law structure of these inequalities has been the subject of much theoretical and empirical work. But their nonequilibrium dynamics, e.g. after a policy change, remains incompletely understood. Here we introduce a thermodynamical theory of inequalities based on the analogy between economic stratification and statistical entropy. Within this framework we identify the combination of upward mobility with precariousness as a fundamental driver of inequality. We formalize this statement by a \"second-law\" inequality displaying upward mobility and precariousness as thermodynamic conjugate variables. We estimate the time scale for the \"relaxation\" of the wealth distribution after a sudden change of the after-tax return on capital. Our method can be generalized to gain insight into the dynamics of inequalities in any Markovian model of socioeconomic interactions.

中文摘要：
世界上有几个国家的经济不平等现象日益严重。继帕累托之后，这些不等式的幂律结构一直是许多理论和实证工作的主题。但它们的非平衡动态，例如在政策改变后，仍不完全清楚。在这里，我们介绍了基于经济分层和统计熵之间类比的热力学不等式理论。在这一框架内，我们将向上流动与不稳定相结合视为不平等的根本驱动力。我们用一个“第二定律”不等式形式化了这一说法，该不等式将向上流动性和不稳定性作为热力学共轭变量。我们估计了税后资本回报突然变化后财富分配“放松”的时间尺度。我们的方法可以推广到任何社会经济相互作用的马尔可夫模型中，以深入了解不平等的动态。
