摘要：
We apply a recently developed unit root test that simultaneously accounts for heteroskedasticity and structural breaks to United States monthly natural gas consumption. We find that United States monthly natural gas consumption is stationary. Our results illustrate the importance of accounting for heteroskedasticity when testing for a unit root in energy consumption with higher frequency data. (C) 2014 Elsevier Ltd. All rights reserved.
