Financial System Development and Economic Growth in Sub-Saharan Africa
(West African Institue of Financial Economic Managemnt, 2016) Egwaikhide, F. O.; Oyinlola, M. A.; Omisakin, O.; Adeniyi, O. A
This paper contributes to the age-old debate on the link between financial development and economic growth by examining the role of monetary policy. There is a possibility that monetary policy enhances financial system performance with attendant impact on growth. To unveil this influence, this paper employs fixed effects and System GMM on data from 28 sub-Saharan African countries over the period 1996 to 2014. Results from the baseline estimation using fixed effects indicate that financial development indicators are negatively and significantly associated with growth for two of the three measures used (LGDP and PGDP), while money growth is positively related albeit insignificantly. The results largely remain the same on interaction with money growth. The coefficients of the interactive terms though largely negative are, however, not significant. The results from System GMM presents a different outcome. First, all measures of financial development turn out positive (except BBD) and insignificant. Financial development equally turns negative but insignificant after interacting with money growth. Overall, monetary policy measures, together with their interactions with financial development indicators, show up as weak growth predictors if not dampening, suggestive of the plausible independence of the nexus on the actions of monetary authorities in these countries.

Foreign Direct Investment, Economic Growth and Financial Sector Development in Small Open Developing Economies
(Elsevier B. V., 2012) Adeniyi, O. A.; Omisakin, O.; Egwaikhide, F. O.; Oyinlola, M. A.
The present paper examines the causal linkage between foreign direct investment (FDI) and economic growth - in Cote d'Ivoire, Gambia, Ghana, Nigeria and Sierra Leone - with financial development accounted for over the period 1970-2005 within a trivariate framework which applies Granger causality tests in a vector error correction (VEC) setting. Three alternative measures of financial sector development - total liquid liabilities, total banking sector credit and credit to the private sector - were employed to capture different ramifications of financial intermediation. Our results support the view that the extent of financial sophistication matters for the benefits of foreign direct investment to register on economic growth in Ghana, Gambia and Sierra Leone depending on the financial indicator used. Nigeria, on the other hand, displays no evidence of any short- or long-run causal flow from FDI to growth with financial deepening accompanying. In sum, therefore, what should be of utmost urgency is concerted efforts in most of these countries, which have typically been in the throes of economic reforms, to upgrade their financial structure to better position them to reap the desirable growth promoting effects of FDI flows.
Oil Price Shocks and the Macroeconomy: Chronicles of Theory and Empirics
(Centre for Petroleum, Energy Economics & Law (CPEEL), 2016) Adeniyi O. A.; Orekoya S. O.; Oyinlola, M. A.; Omisakin, O.
Understanding energy-economy interactions has occupied the attention of academics and policymakers for several decades. The preponderance of empirical attempts in this sphere has focused on the impact of oil price shocks on the aggregate economy in both developed and developing economies. This expansive literature has undoubtedly produced diverse and often conflicting results. In this paper, we therefore provide a survey of this vast literature on the oil shocks-macroeconomy relationship. In particular, we carefully document a considerably elaborate account of both the theoretical propositions as well as empirical exercises in this literature especially over the last three decades on the relationship in question. The core idea behind the foregoing is the hope that this will help both academic researchers and policymakers in the quest for a better understanding of the oil price-macroeconomy nexus particularly in resource dependent settings.
Responsiveness of Trade Flows to Changes in Exchange rate and Relative prices: Evidence from Nigeria
(Eastern Macedonia and Thrace Institute of Technology, 2010) Oyinlola, M. A.; Adeniyi, O. A.; Omisakin, O.
This paper examines the long-run and short-run impacts of exchange rate and price changes on trade flows in Nigeria using exports and imports functions. The bounds testing (ARDL) approach to cointegration is applied on a quarterly data from 1980Q1 to 2007Q4. The results indicate that in both the short-run and long-run Nigeria’s trade flows are chiefly influenced by income- both domestic and foreign-, relative prices, nominal effective exchange rates and the stock of external reserves. The results also reveal that in the long-run, devaluation is more effective than relative prices in altering imports demand at both baseline and augmented models. The reverse is, however, the case for exports demand. Furthermore, the sum of the estimated price elasticities of export and import demand in Nigeria exceeds unity indicating that the Marshall-Lerner (ML) condition holds thus implying that a devalued naira might hold considerable promise as the panacea to rising trade deficits.

Structural Breaks and the Finance-Growth Hypothesis in ECOWAS: Further Empirical Evidence
(Eastern Macedonia and Thrace Institute of Technology, 2014) Omisakin, O.; Adeniyi, O. A.
This study makes a cross sectional case in investigating the validity, or otherwise, of the finance driven growth hypothesis in the ECOWAS countries using annual data from 1970 to 2008 for seven countries namely: Burkina Faso, Cote d’Ivoire, The Gambia, Ghana, Nigeria, Senegal and Togo. In contrast to earlier studies on developing countries, this study specifically tests for the possibility of structural breaks/regime shifts in the finance-growth long run relationship by employing the Gregory and Hansen (1996) residual based test which accounts for endogenous structural break. While the Gregory-Hansen structural break cointegration result confirms the existence of cointegration relationships among the selected countries despite the breakpoints, the Granger-causality test result indicates a general pattern of causality running from financial development to economic growth in most of the countries. Also, the striking feature of the result of our estimated growth model generally lends credent to the importance of financial development in explaining growth dynamics among the selected countries, thus reinforcing the finance-driven growth hypothesis.
Structural Breaks, Parameter Stability and Energy Demand Modelling in Nigeria
(Eastern Macedonia and Thrace Institute of Technology, 2012) Omisakin, O.; Adeniyi, O. A.; Oyinlola, M. A.
This paper extends previous studies in modeling and estimating energy demand functions for both gasoline and kerosene petroleum products for Nigeria from 1977 to 2008. In contrast to earlier studies on Nigeria and other developing countries, this study specifically tests for the possibility of structural breaks/regime shifts and parameter instability in the energy demand functions using more recent and robust techniques. In addition, the study considers an alternative model specification which primarily captures the price-income interaction effects on both gasoline and kerosene demand functions. While the conventional residual-based cointegration tests employed fail to identify any meaningful long run relationship in both functions, the Gregory- Hansen structural break cointegration approach confirms the cointegration relationships despite the breakpoints. Both functions are also found to be stable under the period studied. The elasticity estimates also follow the a priori expectation being inelastic both in the long- and short run for the two functions.
The Dynamics of Stock Prices and Exchange Rate: Evidence from Nigeria
(West African Monetary Institute, 2012) Oyinlola, M. A.; Adeniyi, O. A.; Omisakin, O.
This paper probed the long-run and short-run dynamics between stock prices and exchange rates in Nigeria using the Johansen and Gregory-Hansen cointegration analyses, causality test and Exponentional General Autoregressive Conditional Heteroskedasticity modeling on daily data from January 2, 2002 to August 11, 2011.The results showed that there is no long run relationship between stock prices and exchange rate in Nigeria, albeit, with a structural break date of mid April 2007, which coincides with the period when the stock prices plumped precipitously from the impact of global financial crisis in early 2007. In addition, the results indicated that there is a unidirectional relationship from stock prices to exchange rate and that the EGARCH modeling suggested that a 100% increase in stock prices would lead to a 1.66% appreciation of the exchange rate. Thus, it is imperative for monetary authorities in Nigeria to take into account the role of stock market development in the conduct of its exchange rate policy.
