The Comparative Analysis

Reference of the Study	Method	Findings
IEP (2011)	Correlation Analysis	The authors found a statistically significant and negative correlation between GPI and all WGI (VA, PSAVT, GE, RQ, RL, and CC).
Nadeem et al. (2020)	Unit Root Tests & ARDL Approach	The authors found that VA correlate negatively with terrorism and positively with peace.
Iheonu et al. (2021)	The Ordinary Least Square (OLS), the Tobit regression, and the Quantile Regression (QR)	The authors found that GE increases peace, where the preliminary level of peace is at its lowest level.
Fisher et al. (2021)	Linear Regression	The authors found that RG is highly correlated with sustainability rather than peace.
Deyshappriya (2015)	Linear Regression	The author found that the lack of CC negatively affects the per capita economic growth, while peace stimulates the economic growth of the tested countries.
Nguyen et al. (2021)	Fixed-Effects Regression	The authors found that better GE and public administration benefit peace and prosperity.
Our Study	Feasible Generalized Least Squares (FGLS)	We found that the effects of independent variables [five WGI (VA, PSAVT, GE, RQ, and CC)] on the dependent variable (GPI) are statistically negative and significant, with a significance level of 5%.
