A secondary data in a panel form of 7 banks listed on the Ghana Stock Exchange was examined over a period of 7 years, using a linear multiple regression models. Two key measures of profitability were analyzed in this study that is Return on Asset (ROA) and Return on Equity (ROE). The independent variables included in the regression models were non-performing loans to total loans and advances (NPLR), and loans and advances to total deposits (LATD), bank size, leverage and growth. The results for the study indicated that LATD have significant negative relationship with ROA and ROE but NPLR have insignificant negative relationship with both ROA and ROE. It was recommended that Credit officers must ensure that customers looking for loans meet all the necessary requirements through proper due diligent.

Times series data was used covering the period 1985-2012. The stationary properties of the data were tested using Augmented Dickey-Fuller (ADF) and Phillips Perron (PP) unit root tests. They were all integrated at order I (1). The Johansen Multivariate Cointegration test indicates the existence of long-run equilibrium relationship among the variables in the model. There are no causal relationships between the variables based on the Granger Causality test result. Our equation estimation result indicates a good fit for the model. 96.8% of variations in the dependent variable were as a result of changes in the independent variables. The Durbin-Watson of 1.867475 is a little below the benchmark of 2 but we don’t have to worry about serial correlation problem. Two other diagnostic tests the Breusch-Pagan-Godfrey ...

Data was sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin and Annual reports of various issues. The stationarity of the variables were tested using the Augmented Dickey-Fuller (ADF) unit root test. The ordinary least square (OLS) multiple regression, equation estimation, Johansen multivariate cointegration and Granger Causality analytical techniques were the econometric methods used to analyze the data. Results indicate a significant and positive long run relationship between public health expenditures and economic growth. There was a unidirectional causality between economic growth proxied by GDP and all public health variables in the model namely; Gross Capital Formation (GCF), Total Education Expenditure (TEE) and Total Health Expenditure (THE). The major policy recommendation that emerged from the study is the need for Nigerian policy makers to pay more attention to the health sector and increase its budgetary allocation. Nevertheless the key to good results lies in establishing a strong institutional system that, to the extent possible, links specific expenditure and revenue decisions so as to ensure the usage of the allocated fund as transparently as possible.

Annual time series data 1987-2011 were used as the research sample period. The data were sourced from CBN Statistical Bulletin and Annual Reports of various years. We applied the ADF and PP unit root tests to check the stationarity of the variables. Gross domestic product growth rate and external reserve were stationary at both levels I (0) and I (1). The Johansen cointegration test, equation estimation and Granger causality tests were applied. Johansen cointegration result shows that there exists a long-run equilibrium relationship among the indicators. The Granger causality test between the dependent and independent variables shows a unidirectional causality from exchange rate to BOP, external reserves and gross domestic product growth rate. The indep...

The stationarity of the variables in the model were first tested via the Augmented Dickey-Fuller (ADF) and Phillip Perron (PP) unit root tests and results indicate that all variables were integrated in the order of I (1). Having confirmed the stationarity of the variables (GDPPC, DFIND, INSEC, RINTR, and TSAV),the analyses was pushed further to determine the long-run equilibrium relationship between the variables in the model by using the trace statistics test and the maximum eigenvalue test of the Johansen multivariate cointegration test after the order of linear deterministic trend. The informal financial sector impacts negatively on gross domestic product per-capita in Nigeria. Other variables that impact negatively on GDP are real interest rate, degree of financial depth while total savings has a positive but insignificant relationship. A major policy recomme...

The Granger causality test between the dependent and independent variables shows a unidirectional causality from exchange rate to BOP, external reserves and gross domestic product growth rate. The independent variables indicate a unidirectional causality from • gross domestic product growth rate to external reserve. On the whole this paper has provided empirical evidence that there is a causal relationship between exchange rate and some macroeconomic indicators in Nigeria post SAP. These indicators however impact on the determination of exchange rate in Nigeria. Certain policy implications arise from this finding. It demonstrates the need for monetary authorities to learn from past exchange rate management and come up with a monetary policy framework that complimes the existing exchange rate policy and ensures stability.
