1994 to 2015 on total foreign portfolio investments in liabilities (equity and debt) were collected.Panel data regression analysis incorporating pooled regression, fixed-effects, and random-effects models was estimated. Also, the generalised method of moment estimator was employed to address the problem of endogeneity, usually associated with panel data analysis and as a robustness check for the model. The logit regression model was used to examine the determinant factors of IFRS adoption.Various statistical tests were estimated, such as the diagnostic test, using the histogram and Jarque-Bera statistics, difference-in-difference (DID) test, the unit root test, and the cross-sectional dependence test. The Hausman's chi-square was estimated to determine the best alternative technique between the fixed-effects and random-effects models. Also the Arellano-Bond estimator autocorrelation 〈1〉 and 〈2〉 was used to evaluate the validity of the variable instruments in the model. Besides, the average marginal effect (AME) was estimated for the effect of each covariate on the result. Certain covariates were estimated as control variables in the model.The statistical results show a significant and positive effect of the adoption of IFRS on FPI inflows after the adoption and implementation of IFRS in adopting countries. Equally, the finding further indicates a significant difference in the volume of FPI inflows after the adoption of IFRS than before the adoption, in adopting countries. The statistical estimates also reveal a positive and significant effect of IFRS adoption on FPI in adopting countries, compare with non-adopting IFRS countries where it shows a negative and non-significant relationship. It shows that countries that adopted IFRS experience more inflows in FPI compare with the non-adopting countries in Africa.Furthermore, the logit regression results show that culture, the legal system, political system, investor protection, market capitalisation, and tax were found to be positively significant with the probability of adopting IFRS in the logistic model. This thesis, therefore, suggests that the adoption of IFRS is justified in the selected countries in Africa since the results indicated a positive and significant effect of IFRS adoption on FPI in these countries. Hence, substantiated the assumption of IFRS proponents that adoption will enhance the flow of FPI in adopting countries for economic development. Policies measure to monitor the activities of listed firms and to enforce compliance with IFRS rules and regulations are warranted.These policies would further enable IFRS adopting countries to enhance more flow of FPI.
