Purpose The purpose of this paper is to investigate the determinants of portfolio equity flows to the Sub-Saharan African (SSA) region over the period 1996-2010. Design/methodology/approach The study uses a sample of 14 SSA countries to estimate the baseline regression through employing the system generalized methods of moment dynamic panel estimation framework. To check the robustness of the estimation results, the study further analyses the data set using the random effects-generalized least squares (EGLS) estimator. The Random effects-generalized least squares estimator is also referred to a the Estimated Generalized least Squares (EGLS) estimator. Findings The paper finds a significant positive relationship between financial development and portfolio equity flows. Furthermore, while the study surprisingly finds trade openness to have a significant negative relationship, political stability is found to have a significant positive relationship with portfolio equity. To check for the robustness of these results, the authors further analyse the data set using the random EGLS estimator. The result of the EGLS estimator confirms that there is a robust positive relationship between financial development and portfolio equity flows to SSA. However, the results suggest that neither trade openness nor political stability is a robust determinant of portfolio equity flows to the sub-region. Practical implications Policy measures should aim at enhancing financial sector development, political stability and rule of law. A transparent judicial system that enhances rule of law and deepens democratic governance in countries in the sub-region is critical, but even more critical is deepening the financial sector, given the important role financial development plays in portfolio equity flows as suggested by the findings. A range of measures and appropriate policy responses are therefore needed for countries that have to manage macroeconomic and financial stability risks to deepen the financial sector. Originality/value Most studies on private capital flows to SSA have focussed on foreign direct investment flows with no or scanty evidence on the drivers of portfolio equity flows. This study fills this gap in the literature.
