The present study attempted to test income convergence of the Indian states. For the analysis, the study utilized panel linear and recently developed panel nonlinear unit root tests for the period 1980-1981 to 2007-2008. Use of recently developed panel nonlinear unit root test was the innovation...

We propose a nonlinear heterogeneous panel unit root test for testing the null hypothesis of unit-roots processes against the alternative that allows a proportion of units to be generated by globally stationary ESTAR processes and a remaining non-zero proportion to be generated by unit root...
