The aim of this study is to examine the effect of foreign direct investment (FDI), institutional performance and scientific innovations on environmental degradation (ecological footprints) in selected OIC member countries. In this study, panel data analysis of selected OIC lower-middle income member countries over the period of 2000-2022 has been carried out. Cross-section dependance test has been done to check if there is cross-section dependence present among the variables and then second generation unit rot test has been employed to test the level of stationarity. Upon the recommendation of these tests, Pool Mean Group (PMG) has been applied to investigate the long run associations among the dependent and independent variables. The findings of this study show that FDI  has significant negative impact on ecological footprint and has been acting as environmentally friendly in lower-middle countries. Scientific innovations has significant positive impact on ecological footprint whereas Institutional performance has positive impact on ecological footprint has significant negative impact in high lower-middle income countries. Furthermore, the study has trade openness has positive and significant impact on ecological footprint and GDP per capita has insignificant impact on ecological footprint.

Appropriate economic choices are very much dependent on stability of prices. It will bring certainty regarding purchasing power of the money. This research uses Johenson cointegration approach covering time duration from 1980 to 2018. The empirical estimates of this study shows that in long run all explanatory variables (unemployment, government consumption expenditures, unit price of imports, interest rate and money supply) have momentous influence in accelerating inflation in Pakistan. The findings show that decrease in unemployment and increase in unit value of imports will enhance inflation in long run. Due to the decrease in the government consumption expenditure there will be low investment, low production, and increased aggregate demand associated with high inflation. There exists positive relation between interest rate and inflation. The increase in money supply enhances inflation. Lagged value of error correction model is significant having appropriate sign. Furthermore, this study uses Granger Causality test to check the existence of uni or bi directional relationship among highlighted variables.
