Achieving higher GDP growth rates in Ghana
(Academic Research International, 2013-07) Enu, Patrick; Havi, E.D.K.; Osei-Gyimah, F.; Attah-Obeng, Prudence; Opoku, C.D.K.
The study is on achieving higher GDP growth in Ghana: which sector is to lead. The main objective of this paper was to examine the contributions of the agricultural, service and industrial sectors to economic growth in Ghana. Time series data from 1966 to 2011 on all the variables of interest was obtained from the World Development Indicators 2012 series. The Ordinary Least Squares estimation technique was used for the analysis. The results showed that a 1% increase in the growth of the agricultural sector will cause GDP growth to increase by 0.452849%. Also, a 1% increase in the growth of the services sector will lead to 0.376308% increase in GDP growth. Finally, 1% increase in the growth of the industrial sector will bring 0.1827% increase in GDP growth. All the explanatory variables are statistically significant at the 5% level of significance. It is concluded that the agriculture sector contributed most to the overall growth. It is recommended that for Ghana to achieve higher GDP growth rate, she should activate/strengthen the agricultural sector to lead the growth in the Ghanaian economy
Demand for money and long run stability in Ghana: a cointegration approach
(European Scientific Journal, 2014-05) Havi, Emmanuel Dodzi K.; Enu, Patrick; Opoku, C.D.K.
This paper examined the demand for broad money and its long run stability in Ghana. Multivariate time series approach was used. Since all the variables are integrated of order one, Johansen's cointegration approach is used to establish that the variables are cointegrated. Hence, vector error correction model was used to find the determinants of broad money. Also, CUMSUM and CUMSUMSQ plots are used to check the long run stability of the demand function. It was established that nominal foreign interest rate and expected inflation were long run determinants of demand for money while real income and nominal exchange rate were short run determinants. Also, it was found that the long run broad money demand function was stable over the period under consideration. It was recommended that monetary policy authorities should continue to implement policies that will enhance macroeconomic stability (price stability) and facilitate economic growth.
An Econometric Analysis of the Relationship between Gdp Growth Rate and Exchange Rate in Ghana
(Journal of Economics and Sustainable Development, 2013) Attah-Obeng, Prudence; Enu, Patrick; Osei-Gyimah, F.; Opoku, C.D.K.
This study attempts to examine the relationship between GDP growth rate and exchange rate in Ghana from the period 1980 to 2012. The paper employs the graphing of the scatter diagram for the two variables which are GDP growth rate and exchange rate, establishes the correlation between GDP growth rate and exchange rate using the Pearson’s Product Moment Correlation Coefficient (PPMC) and finally estimates the simple linear regression using OLS. Further tests were performed to test for the presence of autocorrelation, heteroscedasticity and multicollinearity. Autocorrelation and heteroscedasticity were found to be absent. From our analyses, we strongly conclude that there is a positive relationship between GDP growth rate and exchange rate in Ghana which confirms to the theory that undervaluation (high exchange rate) stimulates economic growth in the short run. Therefore, policy makers should stabilise monetary and fiscal policies in the long run
