Foreign Direct Investment and Revenue Generation in Nigeria (1970-2018) (Published)
This study examined the effect of Foreign Direct Investments flow to agriculture, manufacturing and processing, and mining and quarrying subsectors of the Nigerian economy on revenue generation in Nigeria proxied by company income tax and petroleum profit. The six hypotheses that guided the study were formulated in line with the stated objectives and relevant theoretical as well as empirical literature were reviewed and evaluated. The relevant data were extracted from the annual statistical bulletin of the central Bank of Nigeria. Unit root tests were carried out using Augmented Dickey Fuller method which revealed that the variables were integrated at different orders. The autoregressive distributive lag/bound test was used to explore the long run relationship existing among the variables in each model and the result of the bound test showed that the variables in the two models are co-integrated thus the study proceeded in evaluating the long run as well as the co-integrating form in each model. It was found that Foreign Direct Investments to agriculture does not enhance the generation of company income tax and petroleum profit tax in Nigeria in the long run as its coefficient turned out negative and insignificant whereas the coefficient of manufacturing and processing was positive but not significant in relations with company income tax, but negative and non-significant with respect to petroleum profit tax. Going further, Foreign Direct Investments to mining and quarrying had positive and significant relationship with both company income tax and petroleum profit tax generation in Nigeria. The study recommended that Government can by the use of moral suasion; appeal to foreign investors to plough back about 70% of their earnings so as to expand their output as such expansion will invariably increase the company income tax and petroleum profit tax revenues of government. Tax holidays should be granted to investors in Agriculture and Manufacturing and Processing sectors so as to encourage Foreign Direct Investments inflow to these sub-sectors which will no doubt increase output, stimulate growth and increase the government tax revenue generation capacity in Nigeria.

Relevance of Tax Revenue and Economic Growth in Nigeria (2008-2018) (Published)
This study aims at investigating the relevance of tax revenue in driving economic growth in emerging market economy context. . Using data extracted from central bank of Nigeria statistical bulletin for various years and auto-regression estimation model, our study documents the existence of significant and positive relationship between petroleum profit taxes (PPT), Company Income Tax (CIT) on economic growth in Nigeria. Our findings further reveal that Value Added Tax (VAT) and Custom –excise duty (CED) exert negative influence on economic growth. However, the study provide evidence that VAT and CED are insignificant in determining the economic growth in emerging market economy context with special interest in Nigeria This study provide further evidence that the higher the amount of tax revenue generated, the higher the level of economic growth in the economy. There is a recommendation therefore that strong institutional reforms are panacea to prevent leakages of revenue from VAT and CED.

Petroleum Profit Tax Volatility and Economic Growth in Nigeria (Published)
Nigeria has experienced downward slope in its productivity and economic growth. This affects the macroeconomic environment as it is evident that the country has challenges in fixing their roads, challenging in achieving national plan, high rate of unemployment, low quality education and low standards of living. In all these, studies have implicated low and unsteady revenue generation in the country. This study investigated petroleum profit tax volatility on economic growth in Nigeria, using inflation and exchange rates as moderating variables. This study adopted ex post facto research design. Data were obtained from certified sources; namely, National Bureau of Statistics, Central Bank of Nigeria Statistical Bulletin and Federal Inland Revenue Services for the 1981Q1-2017Q4, amounting to one hundred and eight (108) observations. Data were exposed to the scrutiny of the appropriate regulatory agencies for validity and reliability. Pre-estimation tests were conducted using Pearson correlation and stationarity tests. The post-estimation tests included linearity, Heteroskedasticity, Breusch-Godfrey serial Correlation Lagrangian Multiplier and stability test. Data were analyzed using both descriptive and inferential statistics. Findings revealed that Petroleum profit tax volatility had positive and significant effect on EG in Nigeria (R2 = 0.56, β1 = 0.422, t(107) = 6.927, p<0.05). This study concluded that Petroleum profit tax volatility affects economic growth in Nigeria. It was recommended that government should formulate tax policies that will encourage steady tax revenue. In addition, government should ensure prudent application of tax fund to the development of infrastructure that would translate into economic growth

Income from petroleum taxes is the proxy for PPT while economic growth was measured using Gross Domestic Product (GDP). The research adopted expos-facto research as secondary data were used for the analysis. Data were sourced from the Central Bank of Nigeria Statistical Bulletin and the Federal Statistical Bureau. The study covered twelve year period (2004-2015). Time series data were analyzed using the simple linear regression. The results reveals that PPT had positive and significant effect on Nigerian GDP. The study recommends that the government should provide the necessary human and material infrastructures that are needed to support petroleum business so they can earn more income that will boost taxation.
