This study was conducted to explain the consumer demand for sugar-sweetened beverages in Nigeria. The key objective of the study is to estimate expenditure and price elasticity of demand as a first and necessary step to assess the impact of the sugar tax. Data from the 2018-2019 National Living Standard Survey (NLSS), which contains detailed information on household food and beverage consumption as well as socio-economic variables was used. The Quadratic Almost Ideal Demand System was employed for estimation. The expenditure elasticity results revealed all non-alcoholic beverages to be normal goods, sachet water is categorised as a necessity, while bottled water and all sugary drinks were revealed to be luxury beverages. Own-price elasticity for all beverages was ...

We explored the frequently used Toda–Yamamoto model (TY) model, by adopting the TY Modified Wald (MWALD) test approach to causality, Forecast Error Variance Decomposition (FEVD) and Impulse Response Functions (IRFs).The study covered the period 1995 to 2018 (monthly basis), and our findings from MWALD test indicated that there is a uni-directional causality of the log of oil price (lnoilpr) to log of the exchange rate (lnexchr) at 10% level of significance, also there is a contemporaneous response of log of consumer price index (lncpi) to log of exchange rate (lnexchr) and log of interest rate (lnintr), and jointly (lnoilpr, lncpi and lnintr) granger cause lncpi.

This study explores the nexus between monetary policy and economic growth in Nigeria while accounting for the roles of interest rate, money supply, and financial inclusion over a base period of 2004q1 to 2020q4 and a projected period of 30 quarters. Using the dynamic simulation autoregressive distributed lag (ARDL) model, the study finds that in the short run, only the effect of money supply on economic growth is statistically significant. However, in the long run, interest rate, money supply, and financial inclusion have statistically significant effects on economic growth. The results are supported by the plots of the dynamic simulated ARDL, where economic growth response is predicted at various time periods after forcing a ±1% change (positive and negative shocks) in interest rate, money supply, and financial inclusion. We, therefore, recommend among other things an aggressive financial inclusion strategy with clearly defined deliverables and timelines to reduce the percentage of persons excluded from the formal financial system.

This study therefore explores the panel data for the EU-28 countries to assess the dynamic effects of institutional quality, tourism development, financial development, and renewable energy on environmental performance over the period 2002 to 2014. Using a two-step dynamic system generalized method of moments (GMM), the empirical results broadly suggest that institutional quality can be explored to dampen the potential negative effects of tourism and economic growth on environmental performance. In addition, financial development and renewable energy are positively related to environmental performance. This suggests that financial stability and energy consumption transition to renewable energy are necessary requirements to improve environmental performance. The policy implication for this study is that strengthening of institutional quality, financial stability, and adjusting to alternative and clean energy systems are the surest ways to achieve a cleaner and sustainable environment in the EU region.

Specifically, the study evaluated the macroeconomic impact of the agricultural financing reforms on economic growth, and agricultural output. Methodology- This study employed time series data from secondary sources such as the Central Bank of Nigeria (CBN), the National Bureau of Statistics' (NBS) in conjunction with the World Bank Living Standard Measurement Study (LSMS) and Information from the Nigerian Living Standard Survey for 2019 was used to obtain shares of household income and expenditure which covered the period 2010-2022. Applying the economy-wide methodology of Computer General Equilibrium model on reformatted upgraded Social Accounting Matrix for Nigeria, Simulation Designs, and t- test. Findings- The study finds that agricultural financing reforms through a decrease in interest rates on agricultural loans by 10% and 8% have p...

For this purpose, an eclectic approach which combines statistical and historical analytic techniques as well as review of a number of well documented specialized case studies, articles and reports was employed. Evidence from the comparative assessment of Nigeria's ICT sector performance in terms of efficiency and capacity, access, usage, quality, affordability, trade and applications against countries in sub-Saharan Africa and the rest of the world reveal that the sector's efficiency and capacity performance has been remarkable. ICT investment as a proportion of revenue rose significantly compared to the countries in the lower middle-income group which is used as a benchmark during the period 2005 to 2011. Although, there is no doubt that correlation exists between ICT indicators and higher education outputs proxied by enrolment rates, there is ample evidence to show that ICT integration into Nigeria's higher education institutions is still very low. Thus, the study, therefore, suggests the need for the government and private sector to stimulate investment in ICT and education sectors with a view to tackling the problems and challenges inhibiting ICT adoption in Nigeria's higher education institutions. This is of utmost importance if the country must participate meaningfully in the rapidly changing global and knowledge-based economy.

Digitisation is gradually being appreciated in West Africa but its impact on youth unemployment is relatively unknown. Thus, this study aims at filling this research gap by measuring digitisation in two perspectives; internet penetration rate and mobile telephone subscription. The Im-Pesaran-Shin (IPS) unit-root test affirms that the data are suitable for panel ARDL estimation technique. The estimation establishes that youth unemployment, digitisation and the control variables are cointegrated. This study also reveals that digitisation could reduce youth unemployment in West Africa, both at the short-and long-run but not convincing due to low appreciation of digital technologies. In the short-run, the result is consistent in some countries but not same and robust in some others. Thus, the paper concludes that increasing digitisation would enhance employment opportunities for the youths in the West African region.

The study employs the recently developed Lee and Strazicich unit root test with structural breaks, Nonlinear ARDL, and the Hatemi-J causality tests. The result reveals the presence of long-run and short-run asymmetries in the effect of monetary policy shocks on output growth in Nigeria. The results of the long-run effect show that both positive and negative monetary policy rate shocks have positive, elastic, and statistically significant effect on output growth. For the short-run, the results indicate that the effect of negative monetary policy shocks dominate the effects of positive monetary policy rate shocks, while the effect of positive money supply shocks dominates the effect of negative money supply shocks. Furthermore, the study finds evidence in support of the expansionary monetary policy in the long-run. Hence, the recommendations for expansionary monetary policy decision to enhance output growth.

It also examines the effect of entrepreneurship in fostering economic growth and development. The methodology adopted was the narrative-textual case study (NTCS) method, which is preferred because of the absence of sequential data related to entrepreneurship and sustainable economic growth in Nigeria. However, interviews were also conducted. We recommend that there should be proper policy coordination and policy stability; reforms in the educational curriculum to prepare students for self-reliance; and fixing the power sector-Nigeria’s basic infrastructure. When we have flourishing micro, small and medium enterprises (MSMEs), gainful employment will be created, wealth created will be distributed evenly and economy is developed.
