Linkages between investment flows and financial development: causality evidence from selected African countries

This paper introduces previously missing financial components(efficiency, activity and size) in the assessment of the finance-investment nexus. Using VAR models in the perspectives of VECM and short-run Granger causality, three broad findings are established: (1) while finance led investment elasticities are positive, investment elasticities of finance are negative; (2)but for Guinea Bissau, Mozambique and Togo, finance does not seem to engender portfolio investment; (3)contrary to mainstream literature, financial efficiency appears to impact investment more than financial depth. Four policy implications result: (1)extreme caution is needed in the use of single equation analysis for economic forecasts; (2)financial development leads more to investment flows than the other way round; (3) financial allocation efficiency is more relevant as means to attracting investment flows than financial depth; (4) the somewhat heterogeneous character of the findings also point to shortcomings in blanket policies that are not contingent on country-specific trends in the finance-investment nexus.
