The lack of consensus on the relationship between corporate image management and bank performance prompted this research. The study investigates the relationship between corporate image management and performance of deposit money banks in Nigeria between 2007 and 2017. Quantitative approach of methodology where secondary data are collected analysed on relevant variables for eight deposit money banks which include the five tier one lenders and three tier two lenders is applied. Panel data analysis is adopted as the estimating technique. From the result, the random effect result shows that only corporate governance out of the proxies of corporate image management has significant impact on customer retention of the banks. Both corporate social responsibility and environmental responsibility failed to have significant impact on customer retention. The study recommends that that the banks should continue improving on their corporate governance as it is a good measure of corporate image management that contribute significantly to their performance.

The study investigates the macroeconomic impacts of oil price shocks in Nigeria. The study which covers a period from 1980 to 2019 made use of macroeconomic variables such as exchange rate, inflation rate, GDP while oil price is the main exogenous variable. The VAR technique of analysis is adopted and the result shows that oil price shocks do not have direct effect on the GDP but via macroeconomic variable especially exchange rate. The study indicates that exchange rate is the main intermediate variable that passes oil price shocks effect to the Nigerian economy. Evidence of Dutch Disease in Nigeria is also confirmed from the study which further shows the high level of dependency of Nigerian economy on oil.

The study investigated the factors that determine fiscal behavior in Nigeria. The vulnerability of fiscal policy framework in Nigeria to different shocks and the attendant effects on the behavior of fiscal policy are parts of the reasons that prompted this research work. Annual data between 1980 and 2015 on core fiscal variables such as government revenue, government expenditure, fiscal balance, public debt, as well as other variables such as oil price, exchange rate, and inflation rate commodity price among others, are used. The Auto-Regressive Distributed Lag ARDL estimating technique is used to analyze both the long-run and short-run effects of these variables on fiscal behavior in Nigeria. Findings from the study show that fiscal policy in Nigeria is highly vulnerable to shocks from these variables mostly in the short run. Notwithstanding, variables like government revenue, government expenditure, regime of administration, oil price and commodity price volatilities all have sustained effects till the long-run periods. It was discovered that oil price movements is not the only external factor that has pronounced effects on fiscal behavior, but commodity prices volatility generally constitutes an important influential factor in determination of fiscal policy behavior in Nigeria.

The study investigates the nexus between military expenditure and macroeconomic performance in Nigeria between 1980 and 2017. Data on military expenditure and some macroeconomic variables such as output (GDP), exchange rate and inflation rate are used in the study. The Vector Auto-regression technique VAR is applied so as to study the interactions among the variables in the short run. The result shows that military expenditure in Nigeria is significantly influenced by output and exchange rate shocks. It was also revealed that military expenditure does not make significant contributions to the behaviour of output in Nigeria. Military expenditure appears to be insulated against inflation shock since the largest chunk of military expenditure is traded in foreign currency hence less affected by domestic prices.

The study investigated the impact of corporate income tax on the government expenditure in Nigeria. Data on corporate income tax, value added tax, interest rate, gross domestic product, petroleum profit tax and consumer price index were collected and used as independent variable in the study while data on public expenditure were collected and used as independent variable in the estimated model. The ARDL bound test was applied and the result showed that corporate income tax have long run relationship that is significant with government expenditure. Other forms of tax such as value added tax and petroleum profit tax also have significant impact on government expenditure. The study concluded that corporate income tax should be sustained in order to ensure that government continue to fulfill her obligation of provision of social amenities that will promote the economic growth of the country.
