Exploring the existence of environmental Phillips curve in South Asian countries.

Considering the economic activities that trigger alarming situations for the global atmosphere and ecology, this work probes the associations of unemployment (UNE), GDP, population growth (POP), renewable (REN), non-renewable energy use (ENE), and ecological footprints (EF) for South Asian countries. The annual data of 1991-2019 is analyzed for empirical results. This is the first study that employs panel as well as country-specific estimations for South Asian countries by utilizing the Pool mean group (PMG) and autoregressive distributed lag (ARDL) methods, respectively. The study also validates the environmental Phillips curve (EPC) for selected counties. The empirical evidence in all models confirms the positive effects of GDP, ENE, and POP on environmental dilapidation whereas REN and UNE reduce environmental deprivation. The findings confirm the presence of the EPC in South Asian countries. This work presents some important policy instruments for south Asian countries to reduce environmental pollution. In the efforts to improve air quality, these countries have increased unemployment. These nations have to raise the share of renewable energy to the total energy consumption. This will sustain their economies with an increasing employment ratio. At the same time, there is a need to revise the urban policies because the increasing population is also a contributing factor towards environmental degradation.
