2024-03-14T13:49:05+00:00

This paper examines the relationships between good governance, security and sustainable economic development in Nigeria. It focused on good governance as a key driver to sustainable economic development. Security is tied to both social, political and economic growth and development of a nation. The paper revealed good governance as the panacea for enduring security and sustainable economic development in the country; that despite the various developmental plans, the foreign aids received, the natural resources tapped, Nigeria is still far from being a developed nation because of bad governance. It concluded that to maintain security and attain sustainable economic development in Nigeria, good governance that ensures accountability, transparency, sovereignty, civil liberty and rule of law should be given a place of priority in the society. The paper therefore suggests that governance in Nigeria should bestrengthened, put in place appropriate economic policies to attain the set developmental objectives, such as surveillance and protective service delivery, creation of employment opportunities, and programmes that will enhance the aspirations of the citizens.
Government should enforce the rule of law and employ good democratic principles to checkmate the current security challenges that have bedeviled the country.

PREDICTION OF THE NIGERIAN EXCHANGE RATE USING TIME SERIES ANALYSIS FROM (2000 TO 2020)

2024-03-15T02:20:28+00:00

Following the initiation of the structural adjustment program me in 1986, which signaled the start of the devaluation of the domestic currency in relation to the US dollar, the exchange rate policy seems to be crucial for the Nigerian economy. The primary aim of the study is to utilize time series analysis to investigate the currency rate of Nigeria from 2000 to 2020. The 2020 statistical bulletin of the Central Bank of Nigeria presented us with the time series data. The model was derived using the ordinary least squares estimation technique. In order to ensure the proper determination of the Naira's value relative to other currencies, it is imperative for the Central Bank of Nigeria to enforce rigorous restrictions on its foreign exchange policy. The Naira's depreciation as a result of unethical bank practices should be looked into, and guilty parties should be reprimanded appropriately. In order to enhance productivity, it is advisable to provide local manufacturers with subsidies, tax holidays, and various other incentives. In order to enhance foreign currency inflow from exports, it is imperative to execute an industrial plan that establishes a strong link between the manufacturing and agriculture sectors.
