Asymmetric effects of energy consumption and economic growth on ecological footprint: new evidence from Pakistan.

This study explores the asymmetric effects of both aggregate and disaggregate forms of energy consumption along with economic growth on environmental quality for Pakistan covering the period from 1971 to 2014. We have employed unit root test with breaks for stationary checks, BDS test for nonlinearity check and nonlinear autoregressive distributed lag (NARDL) approach for assessing the asymmetric co-integrating relationships among the variables by decomposing them into positive and negative shocks. The empirical findings for aggregate consumption reveal that only negative shocks have a significant impact on ecological footprint.
