Abstract: The aim of our study was to highlight the long-term explanatory factors for the dynamism of the real effective exchange rate in the WAEMU. To get to the end, we used a standard neoclassical model of small open economy to which we made modifications. The Pooled-Mean Group (PMG) methodology for panel data was also used. Our annual data come from the World Bank, the IMF and the BCEAO. These data cover the period 1980-2017. It appears that the fundamentals of the real effective exchange rate in WAEMU are GDP per capita, the terms of trade, the trade balance and foreign direct investment. We recommend strengthening the industrial fabric of the WAEMU countries through the promotion of an incentive tax policy and the diversification of exports. These results negatively affect the maintenance of the fixed exchange rate regime in WAEMU

Abstract: Microfinance is regarded as a panacea for ending the endemic poverty scourge in poor communities. In recent time, upsurge in the number of literature on how microfinance is impacting on the lives of the poor and vulnerable particularly women call for concern. The MFIs provides working capital for poor people to be engage in small businesses and one of the common features is for the loan to create self-employment in non-formal sectors for income-generation. This study examined the impact of microfinance banks on the income level of women beneficiaries in Central and Northern Taraba after joining the microfinance institutions. A survey research was adopted and a sample size of 300 women randomly selected from six local governments with three from each of the two zones used for the study. Statistical Package for Social Sciences (SPSS) was used for data analysis. Result....

Abstract: this research was carried out to analyze the impact of oil revenue on economic growth of Nigeria between 1981 and 2018. Ex – post facto research design was employed; data used for analysis were elicited from Central Bank Statistical Bulletin of 2018. Gross Domestic Product (GDP) was employed as the dependent or effect variable, while oil revenue data was used as a measure of amount of oil revenue accrued to the federal government of Nigeria (independent or causal variable). Foreign Direct Investment (FDI) and Exchange Rate (EXR) were employed as controlled variables. This study employed Auto Regressive Distributed Lag (ARDL) Model to analyze data, other diagnostic tests such as; unit root test, test of Normality, Auto correlation test, Heteroskedasticity test and Breusch-Godfrey Serial Correlation LM test were also carried out and they confirmed the validity and reliability...

Abstract: The paper examined the joint effect of macroeconomic variables such as exchange rate, interest rate, inflation, money supply and degree of openness on small and medium scale enterprises growth in Nigeria spanning from 1999 to 2017 Using Auto Regressive Distributed Lag(ARDL) estimation technique. Secondary sources of data were sourced from CBN Statistical Bulletin, 2017. Relying on the cause and effect theoretical framework, it was found that, Philip Perron (PP) test showed that variables in the series were integrated of difference orders. ARDL bound test revealed that variables in the series moved together in a long run while long run coefficients of ARDL revealed that, money supply and inflation exert insignificant positive..........

Abstract: This study examines the relationship between working capital management and firm performance in Nigeria. To achieve this, we used selected industrial quoted firms in Nigeria that have consistently published their audited financial report between 2014 and 2019. A sample of fifteen (15) firms was used to form the sample of the study to ensure adequate observation for statistical testing. We adopted a panel (balanced) data analysis to identify possible firm's specific types of working capital management in selected Nigerian quoted firms. To this end, we conducted descriptive statistics and correlation analysis to describe the data in the variables in the specified model. Fixed and random effects panel data techniques were conducted as well as the Hausman test which formed basis for selecting the preferred model between fixed and random effects models. Result indicate that debtors management and inventory management both exert negatively and insignificantly on firm performance as proxied by ROA, while cash management show positive but insignificant impact on firm performance. We therefore recommend that efficient management of cash in every business is crucial if the firm is to sustain growth.

Abstract: This study aimed to analyze financial innovations formulated by the National Bank of Rwanda in its monetary policies between 2004 and 2015. The study's findings reveal that financial innovations during the period under review resulted in positive impacts. Financial inclusion widened and deepened, ratios of deposits and credit to the private sector increased, the banking sector became competitive, the number and volume of transactions increased and alternative savings through treasury bills were introduced for the betterment of the banking sector and the economy at large. Resultantly, regional banks established base as due to the fairly stable banking sector. This policy review illustrates that financial innovations affect the account of the monetary policy.

Abstract: Vitamin D-dependent type two rickets (VDDRII) is a rare autosomal recessive disorder caused by mutation in the vitamin D receptor gene, leading to end-organ resistance to 1,25(OH) 2 vitamin D3. VDDR type II causes rachitic changes and alopecia not responsive to vitamin D treatment. Here we present a 7 years old girl with Vitamin D dependent Rickets type II, with dental anomalies.
