英文摘要：
Inequality and its consequences are the subject of intense recent debate. Using a simplified model of the economy, we address the relation between inequality and liquidity, the latter understood as the frequency of economic exchanges. Assuming a Pareto distribution of wealth for the agents, that is consistent with empirical findings, we find an inverse relation between wealth inequality and overall liquidity. We show that an increase in the inequality of wealth results in an even sharper concentration of the liquid financial resources. This leads to a congestion of the flow of goods and the arrest of the economy when the Pareto exponent reaches one.

中文摘要：
不平等及其后果是最近激烈辩论的主题。通过一个简化的经济模型，我们讨论了不平等性和流动性之间的关系，后者被理解为经济交换的频率。假设代理人的财富分布为帕累托分布，这与实证结果一致，我们发现财富不平等与总体流动性之间存在反向关系。我们表明，财富不平等的加剧导致流动性金融资源更加集中。当帕累托指数达到1时，这会导致商品流动的堵塞和经济停滞。
