Most of the studies on the impact of debt on Pakistan economy are backdated to a decade and hence the need to re‐investigate the impact to ascertain the level of effect is encouraged. To investigate the target research, the neoclassical growth equation was expanded by augmenting the equation with other variables of interest (Trade openness and FDI) with the intent of proffering solution in reviving the economy via policy implication. Pakistan's annual data of 1970–2016 were estimated with ARDL and Granger causality approaches for both short‐ and long‐run effects. The main variable external debt is negatively and significantly related to Pakistan's GDP both in the short and long run; Trade openness has a positive and significant impact on the GDP; FDI also has a negative and significant relationship with GDP in the short run but a positive and significant impact on GDP in the long run; and investment has a significantly positive impact on GDP in the short run. Basically from the findings, it is observed that the debt swelling is of hurting effect to the economy. The policy implication should be framed around encouraging the trade openness, but with care, as the first lag is depicting negative impact, FDI must be encouraged with an eye on its long‐term impact on the economy and finally, investment should be given maximum attention in order to crowd out the effect of external debt in the economy.

This research work is developed with interest on the performance of Turkish sustainable development amidst high inflow of foreign direct investment (FDI) and excessive usage of fossil fuels (crude oil and gas). Turkey has been identified as among the countries yet to ratify their agreements with both Kyoto and Paris agreements in fight to reduce the global warming. It is essential to investigate to know if Turkey is promoting climate change as could be among the reason why it fails to work in line the agreement to reduce the global warming. The authors adopted quantile regression (QR) to study the linear relationship that exist among the selected variables in order to have a valid conclusion on the stand of the Turkey towards the control of global warming. Our findings are: A negatively significant relationship between the carbon emission and the agriculture in the all the quantiles except the 90% quantile which shows a positive relationship. Also, the ordinary least square (OLS) estimate which acts as a robust check to the quantile findings confirms a negative relationship between the carbon emission and agriculture. A positively significant relationship is established between energy use and carbon emission in all the quantiles. EU (energy use) is statistically significant for the 30, 40, 50, 70, 80 and 90% quantiles. EU is more statistically significant for the 90% quantile than lower quantiles. Again, a mixed (both positive and negative) relationship is established between foreign direct investment and carbon emission in all the quantiles which shows that FDI is impacting the Turkish environment a mixed manner. It shows that the foreign investors still engage in both clean and dirty production in Turkey. This finding gives support to both pollution halo/haven hypothesis (PHH) in Turkey. However, a 1% point increase in GDP per capita increases the carbon emission both in the 10% quantiles and OLS by 2.82 and 2.797% respectively. This shows a positive relationship that exist between GDP per capita and the carbon emission. GDP is statistically significant for all quantiles, and show that there is a strong relationship between CO2 and GDP. Turkish sustainable policies should focus on promotion of clean FDI and agricultural practice with economic growth anchored on renewable energy sources. [ABSTRACT FROM AUTHOR]
