A monetary history of Ghana

Agyepong, Stephen January 1987 (has links)
The main purpose of the study was to trace the monetary history of Ghana, providing an overall view of how the various monetary regimes in Ghana's history affected the method(s) adopted to finance government budget deficits. The impact of the budget deficits on the money supply process and prices was also analyzed. The study begins with an overview of the various definitions of deficit financing. A brief account of the monetary developments leading to the establishment of the West Africa currency Board in 1912 was given. The study then goes on to show how currency was acquired during the existence of the Currency Board (that is, 1912-57) This led to a discussion of how the Ghana Government financed its budget deficits during this period. The role of the Bank of Ghana in the monetary development after independence was discussed. The persistent Government budget deficits after independence and its effect on the money supply and prices was also discussed. It was found that there is a close connection between changes in the stock of money and changes in prices, and that in Ghana inflation has essentially been a monetary phenomenon. The study concludes with the results of its findings and, their implications for public policy and, topics for further research. A guide to the history of Ghana's currency is provided in appendix A. Appendix B is notes on data used in the study. / Master of Arts

Modeling and Forecasting Ghana's Inflation Rate Under Threshold Models

Antwi, Emmanuel 18 September 2017 (has links)
MSc (Statistics) / Department of Statistics / Over the years researchers have been modeling inflation rate in Ghana using linear models such as Autoregressive Integrated Moving Average (ARIMA), Autoregressive Moving Average (ARMA) and Moving Average (MA). Empirical research however, has shown that financial data, such as inflation rate, does not follow linear patterns. This study seeks to model and forecast inflation in Ghana using nonlinear models and to establish the existence of nonlinear patterns in the monthly rates of inflation between the period January 1981 to August 2016 as obtained from Ghana Statistical Service. Nonlinearity tests were conducted using Keenan and Tsay tests, and based on the results, we rejected the null hypothesis of linearity of monthly rates of inflation. The Augmented Dickey-Fuller (ADF) was performed to test for the presence of stationarity. The test rejected the null Hypothesis of unit root at 5% significant level, and hence we can conclude that the rate of inflation was stationary over the period under consideration. The data were transformed by taking the logarithms to follow nornal distribution, which is a desirable characteristic feature in most time series. Monthly rates of inflation were modeled using threshold models and their fitness and forecasting performance were compared with Autoregressive (AR ) models. Two Threshold models: Self-Exciting Threshold Autoregressive (SETAR) and Logistic Smooth Threshold Autoregressive (LSTAR) models, and two linear models: AR(1) and AR(2), were employed and fitted to the data. The Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC) were used to assess each of the fitted models such that the model with the minimum value of AIC and BIC, was judged the best model. Additionally, the fitted models were compared according to their forecasting performance using a criterion called mean absolute percentage error (MAPE). The model with the minimum MAPE emerged as the best forecast model and then the model was used to forecast monthly inflation rates for the year 2017. The rationale for choosing this type of model is contingent on the behaviour of the time-series data. Also with the history of inflation modeling and forecasting, nonlinear models have proven to perform better than linear models. The study found that the SETAR and LSTAR models fit the data best. The simple AR models however, out-performed the nonlinear models in terms of forecasting. Lastly, looking at the upward trend of the out-sample forecasts, it can be predicted that Ghana would experience double digit inflation in 2017. This would have several impacts on many aspects of the economy and could erode the economic gains i made in the year 2016. Our study has important policy implications for the Central Bank of Ghana which can use the data to put in place coherent monetary and fiscal policies that would put the anticipated increase in inflation under control.
