Income Inequality, Financial Development, and Macroeconomic Fluctuations
研究了收入不平等与消费增长波动之间的关系，发现高收入国家中不平等加剧波动，而低收入国家中不平等反而降低波动，并指出金融发展水平可能解释这一差异。
We examine the relationship between income inequality and variability in aggregate consumption growth. In high-income countries, greater income inequality appears to be associated with more volatility in consumption growth, whereas in lower-income countries, higher levels of income inequality tend to be associated with less volatility. We present evidence that variability in real GDP growth is also related to income inequality in the same way. Our results suggest that the level of financial development may help to explain why the distribution of income affects the short-run variability of consumption and output differently in high-income countries than in low-income countries.
