A Quadratic Modeling and Turning Point Approach	2023	11	.pdf	application/pdf	6770	430	51	Trade Openness and Carbon Dioxide Emissions There is a lack of consensus concerning trade openness and CO2 emission (Karedla et al., 2021). Since our interest is to find out if the relationship between trade openness, FDI, and CO2 emission is non linear or monotonic, we employ a quadratic function which allows the effect of the independent variable (X) on the dependent variable to change.	cache/ajee-1414.pdf	txt/ajee-1414.txt
