This study is the first attempt to investigate the stationarity of natural gas consumption for 50 US states by employing nonlinear unit root test over the period 1960-2008. We concluded that natural gas consumption in approximately over 60% of states follow a nonlinear behavior. While for 27 US states, natural gas consumption is a non-stationary process, then any shock to natural gas consumption is likely to be permanent and such policies will have a permanent impact, for the rest of 23 states natural gas consumption is a stationary process that any shock to natural gas consumption is to be transitory.
