Convergence in Per Capita Energy Consumption among African Countries: Evidence from Sequential Panel Selection Method

Abstract

ABSTRACT: This paper applies a battery of panel unit root procedures to test for convergence in per capita energy consumption among 22 African countries. Specifically, the study implements both the conventional panel unit root testing procedures and the Sequential Panel Selection Method (SPSM). The results from the standard panel unit root tests provide evidence of convergence in per capita energy consumption for the 22 countries as a group. However, these procedures lack the ability to separate the series in the panel into stationary and nonstationary groups. The results from the SPSM procedure provide support for per capita energy consumption convergence for Angola, Mozambique,
