Saving-Investment Nexus in Developing Countries: Does Financial Development Matter?
(Emerald Publishing Limited, 2013) Adeniyi, O. A.; Egwaikhide, F. O.
The Feldstein-Horioka puzzle is re-examined using a sample of 20 sub-Saharan Africa (SSA) countries. Unlike the extant literature we demonstrate the expediency of sustenance of financial sector reforms for the saving-investment nexus in SSA. Findings showed saving retention coefficients similar in magnitude to those already reported for developing countries, particularly SSA. In addition, however, the results uncovered a telling intervening role for financial deepening in the saving-investment space. Going forward, the precise nature and corresponding policy implications of this role should form an integral part of discussions in both academic and policy circles.
The gelling properties of Dillenia indica mucilage in benzyl benzoate emulgel formulations
(University of São Paulo, 2020) Ajala, T. O.; Eraga, S.; Akin-Ajani, O. D
The objective of the study was to evaluate the gelling properties of Dillenia indica mucilage in benzyl benzoate emulgel formulation. Mucilage was extracted from the fruits of Dillenia indica using established methods and characterized by rheology and swelling. Emulsion (F1) was prepared using the continental emulsification method. Gelling agents (2 %w /v) were prepared by dispersing in distilled water with constant stirring at a moderate speed usinga magnetic stirrer. F1 was added to the gel (0-75 %w /w) to obtain emulgel formulations and evaluated using viscosity, globule size, pH, release profiles and kinetic modeling. Data were expressed as mean ± SD, and similarity factor (f2) was used to compare all formulations. Formulation viscosity was significantly higher with carbopol than with Dillenia; globule sizes increased with concentration of gelling agents, and pH reduced as the concentration of Dillenia increased. All formulations showed controlled release properties with t80 ranging between 114 and 660 min. The release was governed by Korsmeyer-Peppas model. Formulation F5 prepared with 50 % Dillenia showed highest similarity to F4 prepared with 75 %w /w carbopol. Dillenia indica demonstrated acceptable gelling properties comparable with that of carbopol and could be improved for use in emulgel formulations.

Oil Revenue, Institutions and Macroeconomic Indicators in Nigeria
(OPEC Energy Review 37(1), pp. 30-52, 2013) Ushie, V.; Adeniyi, O. A.; Akongwale, S.
The influx of massive revenues during periods of abnormally high oil prices creates enormous challenges for policy-makers in oil-producing countries. In Nigeria, the prudent utilisation of oil revenues has remained elusive for policy-makers over time. While the country has earned sizeable oil revenues from its natural endowment, poverty and income inequality have been persistent. This study tests the sensitivity of several important macroeconomic indicators to oil revenue shocks. We additionally test for the effect of ‘institutional quality’, in recognition of the important role played by the domestic institutional context in shaping the policy responses adopted by successive Nigerian governments to oil windfalls over time. The sensitivity analysis supports the general view that fluctuations in oil revenues have resulted in inflation, lower output growth and real exchange rate appreciation in Nigeria. More importantly, the aforementioned institutional variable is found to be very significant. This finding is consistent with the general assessment of fiscal performance in Nigeria during oil windfalls as being driven by domestic institutional dynamics. Ostentatious public consumption widened fiscal deficits, and government spending has been highly pro-cyclical during windfall episodes. In conclusion, the study offers appropriate policy recommendations, which could be adopted to enhance the management of future oil windfalls in Nigeria.
