This study investigated the impact of crude oil price and exchange rate on economic growth in Nigeria using an autoregressive distributed lag model covering the period from 1982-2018. The results indicated that crude oil price and exchange rate have significant positive impact on economic growth in both the long-run and the short-run periods. The findings suggested that crude oil price and exchange rate which are the focal points of the study, could affect economic growth in both the long-run and the short-run. Therefore government should diversify its earnings in agriculture, industrialization and investment in order to reduce the heavy reliance on crude oil and income fluctuation resulting from the fluctuation in crude oil prices.
This empirical research examined the impact of population growth on unemployment in Nigeria. The study applied annual time series data from 1991 to 2017. The data on population, unemployment, consumer price index, exchange rate and foreign direct investment were tested for unit root using ADF, PP and KPSS unit root tests. The results from the ADF and PP tests revealed that all the variables were stationary at first difference except CPI that is stationary at level. While the KPSS units root test result shows that all the variables are stationary at level. The variables were co-integrated as shown by the Johansen Juselius test for co-integration. The Dynamic Ordinary Least Squares (DOLS) were used in the process of estimating the model. The main results disclosed that population and exchange rate impacted positively with unemployment. Whereas consumer price index, GDP per capita and foreign direct investment impacted negatively thereby reducing the rate of unemployment in the long-run. Government should focus more on attracting foreign direct investment, increasing GDP per capita and the desired rate of consumer price index in order to control the rate of unemployment in the country.
The study investigates the impact of corona virus out break on the global energy demand in china using the time series daily data spanning the period 23 rd January to 8 th February 2020 on total cases of corona virus, total population of china, total exchange rate of Chinese currency and international crude oil prices. Using the Philip Perron unit root test for testing the stationarity of the variables, the results revealed that total cases of corona virus, international crude oil price and total population are stationary at level while official exchange of Chinese currency is stationary at first difference. After the testing the existence of co-integration relationship among the variables using Engle Granger test for co-integration, the ordinary least squares test result revealed that total population has positive and significant impact on total cases of corona virus while crude oil price is negative and significantly related to the cases of the virus. The official exchange rate is also negative but insignificant in explaining the cases of the virus. Base on the findings, the researchers therefore recommend that the oil producing countries should reduce their supply of crude oil to the country affected with the virus in order to push the price upward to the desired level and the government of the affected country should maintain restrictions with regards to the movement of its population in order to tackled the spread of the virus.
This study investigates the impact of crude oil price on exchange rate in Nigeria using an autoregressive distributed lag (ARDL) model covering the period from 1983-2017. The results showed that crude oil price has negative and significant impact on exchange rate in both the long run and the short run whereas oil revenue and Gross Domestic Products have significant positive impact on exchange rate also in both the long-run and the short-run periods. The findings suggested that crude oil price which is the focal point of the study, could affect exchange rate in the both the long-run and the short-run. Therefore the study concludes that crude oil price, oil revenue and Gross domestic Products are among the determinants of exchange rate in Nigeria.
