African heads of state have made several commitments to make the functioning of the agriculture sector sustainable. The two most prominent of these commitments are the Maputo and Malabo declarations. The Maputo declaration stated that country should allocate at least 10 percent of the total fiscal expenditure so as to attain 6 percent agricultural growth. This study investigates the effects of public agriculture spending on agricultural output. This was conducted through the effective quality channels of public agriculture spending such as credit budget channel, research budget channel, fertilizer consumption channel and energy budget channel in sub-Saharan Africa. The study was essential has very limited studies have examined the effects of agriculture public spending to feeding sub-Saharan Africa. The paper adopted the system generalized method of moment to control for endogeneity, simultaneity, and reverse causality. The findings show that public spending enhances agriculture per...

The COVID-19 crisis has attracted attention worldwide to the supply chain disruptions and resilience. Several supply chain risk management approaches have been revisited or reapplied such as collaborative resource sharing. This study aimed to investigate the current academic state of art and advances in using collaborative resources sharing as a reactive method to facilitate supply chain recovery in the presence of disruptive events. More specifically we considered the role of different collaborative resource sharing strategies that organizations can adopt to support supply chain functionalities during times of disruption. We conducted a systematic literature review (SLR) to analyze academic articles that were published online from 2000 to 2022. In order to analyze the literature, we adopted a combination of text-mining, automatic and manual categorization of selected articles, and exploratory analyses such as cluster analysis and relational indicators. We also consider the machine ...

The study ascertains the extent of mispricing in equity portfolios and mispricing–investment relation using the post financial crisis stock information. A risk-augmented capital asset pricing model (CAPM) is specified to estimate the mispricing in equity portfolios while the mispricing– investment relationship model follows Mohammed (2006). For all the estimations, the regressions are run on daily data from 5 January 2010 to 30 December 2015. First, the results show the presence of transient mispricing in the portfolios’ returns of African equities regardless of the firms’ liquidity and volatility levels. More so, stronger mispricing is observed using an alternative specification. Second, mispricing causes significant divestment in big-size portfolios. Meanwhile, it is less important in small and medium-size portfolios. It further causes overinvestment in medium stock portfolios while effects of over-valuation prove to be velvety on portfolios across board. The conclusion is that mi...

The paper examines the validity of the Ricardian Equivalence Theorem (RET) as a result of the continuous rising of fiscal debt in Nigeria. It makes use of data generated from a Nigerian population survey in purposely selected areas in Lagos State, Nigeria. The survey is conducted in the third quarter of 2018, with a randomly selected representation of 3000 Nigerians. The paper asked whether the respondents have altered their consumption attitude as a result of expected changes in fiscal taxes particularly, the value added tax (VAT) and growing fiscal debt that persisted for a decade (2008 – 2018). The paper concludes that in general, the RET does not hold in Nigeria. Conversely, the findings spotted that small proportion of the respondents believed that smaller proportion of their income is consumed in response to fiscal debt accumulation. A robustness test was conducted using multinominal logit regression, and found that individuals’ consumption responses are significantly related ...

With the increasing rate of youth unemployment in the country, Nigeria’s youths have invested their commitments (time, money and intrinsic efforts) to several gambling avenues such as Baba Ijebu, Naira Bet, Westen Lotto Bet, etc. to source for finance to meet up their daily expenses and reduce the crime rate that would have engaged in as a result of high rate of unemployment. The aggregate unemployment rate is 70%, while youth unemployment accounts for about 58%. With the huge rate of youth unemployment in the country, the study intends to examine the participation level of youths in gambling in Lagos State. It further inspects the effects of youth gambling on household welfare and spending. Methods used by the paper include: a two-stage survey design, a qualitative component that comprises of the targeted focus group discussions and probit modelling to estimate how important the identified challenges are. The paper found that Nigeria’s unemployed youths have utmost interest in gamb...

This study examined the impact of agriculture sector growth on unemployment level as well as the direction of causality between agricultural sector output and unemployment level in Nigeria. Secondary annual time series data between 1981 and 2016 were used for the study. Data on unemployment rate, agriculture sector output, public expenditure and industrial output were obtained from the Central Bank of Nigeria’s statistical Bulletin while data on FDI and population growth were obtained from the World Bank World Development Indicators. The data were analyzed using ADF (Augmented Dickey Fuller Test) unit root test, Autoregressive distributed lag Bounds test of cointegration, Autoregressive distributed lag error correction model estimation and Granger causality. The results of ADF unit root test revealed variables were at different orders of integration, the ARDL bounds test revealed cointegration between variables, and the Autoregressive distributed lag error correction model estimatio...

Purpose The agriculture sector in Africa is a major employer, but production levels have fallen short of demand. To match future demand, public investment in research and development (R&D) is required. The purpose of this paper is to investigate how foreign direct investments (FDIs) moderate the effects of public R&D on Africa’s agricultural production. Design/methodology/approach This study estimates an unbalanced panel fixed effect model that consists of 28 African countries covering the period 1980–2014. Findings Public R&D increases production in the agriculture sector, however, the effects reverse after ten years. Though FDIs have direct positive effects on production, indirectly, it reduces the productivity potential of public R&D due to the possible dependency syndrome associated with FDIs. Traditional inputs like land, capital, and labour and good political institutions positively drive production, but adverse changes in the weather reduce production. Practical implications ...

The paper examines the validity of the Ricardian Equivalence Theorem (RET) as a result of the continuous rising of fiscal debt in Nigeria. It makes use of data generated from a Nigerian population survey in purposely selected areas in Lagos State, Nigeria. The survey is conducted in the third quarter of 2018, with a randomly selected representation of 3000 Nigerians. The paper asked whether the respondents have altered their consumption attitude as a result of expected changes in fiscal taxes particularly, the value added tax (VAT) and growing fiscal debt that persisted for a decade (2008-2018). The paper concludes that in general, the RET does not hold in Nigeria. Conversely, the findings spotted that small proportion of the respondents believed that smaller proportion of their income is consumed in response to fiscal debt accumulation. A robustness test was conducted using multinominal logit regression, and found that individuals' consumption responses are significantly related to their economic situation and time preferences. It therefore recommends that fiscal policy should be more effective so as to stimulate economic activity through consumption and aggregate market activities.

The paper examines the asymmetric effects of exchange rate and inflation on output growth in WAMZ countries. Most of the countries in WAMZ are import dependent, and it is obvious that any shock in exchange rate will affect domestic inflation and by implication influence the pattern of output growth. Therefore, forming a monetary union necessitates understanding of exchange and inflation rates asymmetric effects on output growth in these countries. Quarterly data on real exchange rate, inflation and output growth were garnered for twenty-four (24) years. Findings from both the linear Autoregressive Distributed Lag (ARDL) and Non-Linear ARDL models show that the positive asymmetric shock of inflation increases output growth; while the negative asymmetric shock of inflation reduces WAMZ growth rate of output. More so, positive real exchange rate has negative asymmetric shock on WAMZ output growth. This indicates that the aftermath of currency appreciation in West Africa Monetary Zone (WAMZ) has negative impact on output growth of member countries. Howbeit, the size of the effect is considerably large, however, the period in which the complete effect is pass-through to output growth is four quartiles, which is approximately a year. The paper recommends that effective policy on inflation specifically, policy to increase positive asymmetric shocks in inflation before the complete pass-through of real exchange rate effects will either reverse or reduce the effects of exchange rate asymmetric shocks on output growth in these countries.

The research offers crucial insights about the contribution of crowdfunding to facilitate the attainment of critical factors for successful business ventures. With extensive leverage on findings from existing literature, personal interview and group discussions, the research explores three functional areas of business venture. This consists of the early start life of business, meeting with pre-sales and pre-order demands from customers, and supporting incremental rounds of financing/raising capital. It also clarify the impact of crowdfunding in circumventing the funding challenges encountered by business venture in these identified functional areas. The findings show that importantly, crowdfunding is a positive thrust that business ventures should embrace to overcome the funding challenges at these three functional areas.

This paper ascertains the extent of mispricing in equity portfolios, mispricing-divestment relation and the role of African equities as risk diversification strategies during commodity markets turbulence. Following Baur and Lucey (2010), one identifies arbitrary commodity market crisis to be 1%, 5% and 10% declining moments in returns. However, their approach is extended by using African equities as a safe haven against gold. A risk-augmented CAPM is specified to estimate the mispricing in equity portfolios while the risk diversification model follows Baur and Lucey (2010). For all the estimations, the regressions are run on daily data from 5th January, 2010 to 30th December, 2015. First, the results show the presence of transient mispricing in the portfolios returns of African equities regardless of the firms’ liquidity and volatility levels.

With the increasing rate of youth unemployment in the country, Nigeria’s youths have invested their time, money, and intrinsic efforts in several gambling avenues, such as Baba Ijebu, Naira Bet, Western Lotto Bet, and others. These commitments provide them with financial resources to meet daily expenses, augment low incomes arising from unemployment, and help mitigate the rising crime rate that results from the high unemployment rate. The overall unemployment rate for the population is 70%, and youth unemployment accounts for about 58%. This study examined the participation of youths in gambling in Lagos State and the effects of youth gambling on household welfare and spending. A two-stage survey design was used: a qualitative component comprising targeted focus group discussions and probit modelling to estimate the importance of the identified challenges. The results showed that Nigeria’s unemployed youths have an intense interest in gambling to sustain their income sources and to ...

The development of the financial sector has been a major growth driver in all economies, especially in emerging economies. Part of the financial innovations in the sector in recent times is the electronic payment system. Several studies in developed countries have substantiated the positive transformation of this financial innovation. This paper therefore contributes to this debate with three research innovations: first, it adopts a new measure of bank performance—the sortino index; second, it relates market risk exposure of banks to electronic payment technologies; and third, it controls for “without effects” of these innovations on bank performance using interacting dummies. Based on the time dimensional and panel least square models, it finds that bank performance increased after the adoption of electronic payment technologies. Finally, its findings show that bank performance contradicts autoregressive and random walk processes and thus implies that investors should not be distur...
