Abstract
We study the impact of financial deepening on economic volatility for Sub-Saharan African countries (SSA) from 1982 to 2019 in a trivariate panel cointegration framework. Two measures, broad money and domestic credit as a percentage of GDP, are used to capture the financial deepening holistically. The analysis considers the possibility of cross-sectional heterogeneity and endogenous structural breaks. The study finds that financial deepening indicators share a long-term relationship with economic volatility. Panel parameter estimates by Dynamic OLS (ordinary least square), Pooled Mean Group, and Fully Modified OLS suggest that broad money influences economic volatility positively when financial deepening is represented by broad money. On the other hand, when domestic credit is chosen as the proxy for financial deepening, the impact is negative. Thus, while domestic credit helps lower economic volatility, broad money increases it. At the same time, the estimators indicate that broad money has a stronger relationship with economic volatility as compared to domestic credit for SSA countries. The study offers policy suggestions based on the empirical findings that emphasise financial inclusion and wider credit availability through the spread of the banking network for attaining the goal of reduced GDP volatility and steady economic development. An increase in the money supply might lead to increased economic activity in the short run but results in increased GDP volatility over the longer term.

Notes
The data include information on the following SSA countries: Benin, Botswana, Burkina Faso, Cameroon, Congo, Rep., Gabon, Kenya, Lesotho, Madagascar, Mali, Mauritius, Rwanda, Senegal, Sierra Leone, South Africa, Sudan, Togo.
Results are available on request.
We also examine panel unit root tests using the Levin et al. (LL) test (Levin et al. 2002) and the IPS (Im et al. 2003). While the LL test does not allow the autoregressive coefficient to vary, the IPS test considers its heterogeneity. Both tests assume cross-sectional independence. These tests show GDP volatility to be I(0) while the other three variables—broad money, domestic credit, and trade—are I(1).
