Inequality convergence revisited: Evidence from stationarity panel tests with breaks and cross correlation

  • Lin, Pei-Chien
  • Huang, Ho-Chuan (River)

This paper empirically examines whether there exists stochastic convergence of income inequality among 48 contiguous states within the US over the 1916–2005 period. For that purpose, we employ the recently developed panel stationarity test of Carrion-i-Silvestre, Del Barrio-Castro and López-Bazo (2005), which assumes a highly flexible trend function by incorporating an unknown number of structural breaks. In addition, the issues of cross-sectional dependence as well as control for finite-sample bias are accommodated through bootstrap methods. Overall, for the US case, our analysis provides strong evidence in support of the hypothesis of inter-state inequality convergence. Moreover, the results are robust to alternative inequality measures applied, different notions of stochastic convergence defined, and alternative panel stationary test employed.
