Links between economic growth and inequality are of growing interest for researchers and policy makers. Previous studies of this relationship have focused mainly on inequalities in income rather than in

wealth. Yet from many perspectives wealth inequality is arguably more important. Using a new panel data set from Credit Suisse for 45 sample countries over the period 2000–2012, this study investigates the effects of wealth inequality on economic growth.

**Empirical results from system GMM estimation suggest that the wealth inequality is negatively associated with cross-country economic growth. T**his result is robust to alternative estimators and measures of wealth inequality, as well as the econometric specification. Further empirical investigation reveals that impact of wealth inequality on growth is mitigated by better governance.

**mpirical results suggest that the rising wealth inequality significantly hampers overall economic freedom, property rights protection, freedom to trade, soundness of money and regulatory environment. Furthermore, this negative effect of wealth inequality is reinforced at a lower level of democracy. **These findings are robust to alternative measures of wealth inequality, economic freedom, treatment for endogeneity, and model specification.

We test whether income inequality undermines female and male life expectancy in the United States. We employ data for all 50 states and the District of Columbia and two-way fixed effects to model state-level average life expectancy as a function of multiple income inequality measures and time-varying characteristics.

**We find that state-level income inequality is inversely associated with female and male life expectancy. We observe this general pattern across four measures of income inequality and under the rigorous conditions of state-specific and year-specific fixed effects**. If income inequality undermines life expectancy, redistribution policies could actually improve the health of states.
