H2. monetary policy variables influence output in the short-term but not in the long-run in the CFA zones. First, the absence of cointegration among real output and the monetary policy variables in both zones confirm the neutrality of money in the long term. With the exception of overall money supply, the significant effect of money on output in the short-run is more relevant in the UEMOA zone, than in the CEMAC zone in which only financial system efficiency and financial activity are significant. Practical implications – First, compared to the CEMAC region, the UEMOA zone’s monetary authority has more policy instruments for offsetting output shocks but fewer instruments for the management of short-run inflation. Second, the CEMAC region is more inclined to non-traditional policy regimes while the UEMOA zone dances more to the tune of traditional discretionary monetary policy arrangements. A wide range of policy implications are discussed. Inter alia: implications for the long-run neutrality of money and business cycles; implications for credit expansions and inflationary tendencies; implications of the findings to the ongoing debate; country-specific implications and measures of fighting surplus liquidity.

Design/methodology/approach – In framing the financial dimension in a more concrete and tractable manner, the author examines the concerns of how domestic financial initial dynamics of depth (economic and financial systems), efficiency (banking and financial systems), activity (banking and financial systems) and size, play out in the financial development benefits of financial globalization. The estimation approach consists of assessing the impact of financial globalization through out the conditional distributions of domestic financial development dynamics. Findings – The introduction of previously missing financial dimensions into the debate generates a number of important findings. Only financial initial (threshold) conditions of size are necessary to materialize the benefits of financial globalization. While financial depth only partially validates the hypothesis, dynamics of efficiency and activity (credit) do not confirm the hypothesis. Practical implications – Addressing the issue of surplus liquidity in African financial institutions could improve the benefits of financial size and potentially reverse the trends of financial efficiency and activity. Depending on the context of sampled countries, the appropriate role of policy has always been either to stem the tide of capital flows or encourage them. Policymakers who have been viewing their challenges exclusively from the latter perspective for benefits in growth (finance) might be getting the financial dynamics badly wrong.
