Abstract:
This study replicates Leigh and Jencks’ (2007) analysis of the relationship between income inequality and mortality. Using L&J’s preferred specification, I am able to closely reproduce their original findings after reconstructing their data from original sources. When I use multiple imputation instead of their method of linear interpolation, I largely confirm their results. When I extend their data from 2003 to 2018, I again do not find a significant relationship between income inequality and mortality. As a result, I conclude that my replication exercise confirms L&J’s results, providing even stronger evidence for the view that income inequality is not adversely related to mortality.
