This study applies wavelet coherency analysis to examine the relationship between the U.S. per capita real GDP and six income inequality measures over the period 1917 to 2012. Wavelet analysis allows the simultaneous examination of correlation and causality between the two series in both the...

This paper uses a cross-state panel for the United States over the 1976 to 2007 period to assess the relationship between income inequality and the inflation rate. Employing a semiparametric instrument variable (IV) estimator, we find that the relationship depends on the level of the inflation...

This paper examines the role of financial development on U.S. state-level income inequality in the 50 states from 1976 to 2011, using fixed-effect estimation. We find robust results whereby financial development linearly increases income inequality for the 50 states. When we divide 50 states...

This paper contributes to the sparse literature on inequality convergence by empirically testing convergence across the U.S. States. This sample period encompasses a series of different periods that are discussed in the existing literature -- the Great Depression (1929-1944), the Great...
