This study investigated the gender wage gap in Nigeria by analysing two waves of household surveys (in 2003–2004 and 2018–2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

The study applied an extension of Oaxaca–Blinder decomposition that relies on the re-centred influence function (RIF) regressions to analyse the gender wage gap at all points along the wage distribution.

The results unambiguously show that there is a significant gender wage gap in Nigeria at all points along the wage distribution, such that for the two surveys used and after nearly two decades, men still earn more than women. That is, the log wage difference between males and females is statistically significant at all points between the 10th and the 90th quantiles. In 2003–2004 period, the authors found that most of the wage difference was significantly accounted for by the wage structure effect, whilst the composition effect was negative and only significant at the bottom of the wage distribution. Since the 2018–2019 period, the authors found that there has been a visible change such that most of the gender wage gap is now accounted for by the composition effect at all points along the wage distribution. Another interesting finding is that there has been a general decline in the gender wage gap along the entire wage distribution, such that inequality was higher in 2003–2004 than in 2018–2019. This decline is bigger at the top than at the bottom of the wage distribution. The authors also found that, contrary to some of the studies on the wage gap, the raw gaps for the two surveys appear to show inverted U-shape, but the gap has fallen quickly since the 2018–2019 period. Thus, the authors found strong evidence of a “sticky floor” compared to a “glass ceiling” effect in both periods, and this becomes more pronounced over time. In terms of the contributions of individual covariates on gender pay gap in Nigeria, the authors found that urban residence, unionisation, education and occupation variables exhibit major influence. However, the effects of covariates on the composition and wage structure components of the wage gap have changed over time.

The major policy implication of these findings is that to address the gender wage gap in Nigeria, policy should focus more on how labour is rewarded and improving human capital for women.

This study is a novel paper in Nigeria that has investigated the gender wage gap in Nigeria by extending the focus of literature in three ways. First, the authors applied an extension of Oaxaca–Blinder decomposition that relies on the RIF regressions to analyse the gender wage gap at all points along the wage distribution. Second, the authors used sample selection bias to account for the non-randomness of participation in wage employment. And third, the authors applied similar analysis to two waves of household surveys (in 2003/2004 and 2018/2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

Enhancing household consumption and reducing inequality are among the fundamental goals of many developing countries. The purpose of this study therefore is to disaggregate household consumption expenditure into food and non-food and, thus, decompose inequality into within- and between-groups.

The study adopts generalised entropy (GE) measures. Second, the study uses regression-based inequality decomposition to ascertain the determinants of inequality in food and non-food expenditure using household demographic and socioeconomic characteristics as covariates.

The results show that non-food expenditure is the major source of inequality in household consumption expenditure in both urban and rural areas with inequality coefficients of above 0.6 compared to about 0.4 for food expenditure. The decompositions also show that within-group inequalities for non-food and food expenditure are, respectively, 0.97 and 0.365 using the Theil index, while between-group inequalities for non-food and food are, respectively, 0.016 and 0.035. Furthermore, the regression-based inequality decompositions show that variables such as living in rural areas, household size, household dwelling and household dwelling characteristics account for the significant proportion of inequality in food and non-food expenditure.

The policy implication of the findings, among others, is that policies should focus on addressing inequality within rural and urban areas, especially with respect to non-food expenditure than in inequality existing between urban and rural areas. These non-food expenditures include expenditure in education, health, energy, accommodation, water and sanitation.

The purpose of this paper is to highlight the challenges of Nigerian Professional Football League teams at the club level, with a view to aligning this with developments at the country level, and especially so in the aftermath of the 2014 FIFA World Cup in Brazil – an international event – where Nigeria participated alongside four others – Algeria, Cameroon, Ghana and Ivory Coast.

The meta-analysis adopts a qualitative research approach, drawing upon a review of secondary data sources and the observation technique.

Although Nigeria’s first team players ply their trade in Europe, there remains a challenge epitomised by the “disconnect” between the domestic league and the national team composition. As a consequence, brand ambassadors are proposed as one of the key conduits for re-aligning the identified disconnect.

The dual focus on club level and a single country – albeit in the light of Nigeria, former African champions, poses a limitation as the domestic league in that country may not be representative of others across the continent. However, some insight is also derived from developments in another African football giant – i.e. Ghana, runners-up of the recently concluded 2015 African Nations Cup.

In the long history of the FIFA Football World Cup, only three African teams have ever reached the quarter-finals – notably Cameroon in 1990, Senegal in 2002 and Ghana in 2010. Although the Super Eagles relished the label of African Champions going in the World Cup finals, they remain incapacitated, having failed to “fly” into the round of 16 since their 1994 debut. Furthermore, the alignment at the micro or club level to the meso or country level remains to be investigated at both scholarly and policy levels.

There are success stories on the management and development of football in Africa and as the case of Nigeria demonstrates, Stephen Keshi, the national coach, symbolises missed opportunities – i.e. brand ambassadors – to increase visibility and engagement with the domestic league.

This is one of the very few studies that have sought to highlight the misalignment between club and country within the research context of Africa. It is also one of the few papers that have called on the need for brand ambassadors as a means of bridging the gap in this area.

Banking sector reforms can impact the development of the real sector. However, there is very little known about this impact on the construction sector in a developing country context. This study aims to evaluate the impact of the banking sector reform on the construction output (CNS) using the banking sector reform in Nigeria in 2005 (2005 Banking Sector Reform Programme [BSRP]) as a case.

This study used econometric methodology comprising unit root test for stationarity, Johansen test for cointegration, analysis of variance (ANOVA) and the analysis of covariance. Time series data covering a period from 1981 to 2017 (37 years) about the banking and construction sector performances are analyzed using ten-time series equations.

The ANOVA estimates reveal that the 2005 BSRP positively impacted the CNS and construction sector growth rate. However, the ANOVA estimates reveal that the gross domestic product (GDP) and bank total loan had a positive impact on CNS in the period (1981–2017) before and after the 2005 BSRP, and consequently removing the effect of the 2005 BSRP on CNS.

This paper concludes that the banking sector reform has a positive impact on CNS in the Nigerian construction industry. The impact is greater and lasting when the reform is directly targeted at improving CNS.

This study provides empirical evidence of the dependence between banking sector reform and construction sector performance in a developing country context. Also, this study demonstrates the relationship between GDP, banking sector reform and construction sector performance in a developing country context.

Broom production and marketing is a local business industry operated by women in Nigeria. This activity serves not only as a source of livelihood to women but also has created job opportunities for the teeming unemployed persons in the rural areas. This paper aims to examine socioeconomic effects of small-scale women businesses in broom production and marketing industry in Nigeria with a view to analyze small-scale women businesses in Igbo Eze North District of Nigeria.

New economic theory was used to guide the study. The study adopted a quantitative research design comprising of semi-structured interviews, field observations, reference to relevant literature and a questionnaire survey of 340 female households engaged in broom production and marketing from fifteen villages. This sample size was selected using purposive sampling technique and Yamane formula. Frequencies and Spearman rank correlation were used to analyze the data.

The study found that broom production and marketing have an effect on the socioeconomic development of the people. The study found a positive relationship between broom production and marketing and income generated, education and occupation in the study area. This study concluded by suggesting that broom production in the study area should be mechanized to improve the quality and quantity of broom produced in the area.

This study has shown that Nigerian women have good potentials for entrepreneurship. Both the society and the government authorities should work together in supporting female ventures in Nigeria.

The paper empirically has shown the socioeconomic effects of small-scale women businesses in broom production and marketing on local household of Igbo Eze North District of Nigeria. This study stands as the first in Nigeria to consider the effects of broom production and marketing and how women in this part of Nigeria have used it to create job opportunities and opportunities of income for themselves and their families.

This study aims to explore possible ways to promote uptake and integration of climate-smart agriculture (CSA)-Technologies, Innovations and Management Practices (TIMPS) into policy and practice in Nigeria through the development of actionable roadmaps to facilitate the process.

Two hundred and fifty-two stakeholders for the policy discourse and survey were purposively drawn from both government and private agencies, NGOs and community-based associations from the six geo-political zones of the country. Data collection was done using a mixed method comprising questionnaire administration, in-depth interviews and panel discussion. Data collected was summarised using descriptive statistics.

The major findings were lack of existing policies on CSA, lack of farmers’ awareness of CSA-TIMPs, neglect of extension programmes that can help to enlighten farmers on the importance of CSA and insufficient extension personnel to cater for farmers’ needs. Challenges to CSA-TIMPs uptake in Nigeria were: insufficient funding and support by government in programme planning and implementation, policy inconsistencies and poor farmers’ attitude and resistance to change.

This research will facilitate CSA uptake and integration through the provision of data for informed decision and action by the responsible agencies.

Suggested actionable roadmaps across the zones were robust awareness campaign and advocacy on uptake of CSA-TIMPs through e-extension, community TV/radio in local dialects; revitalisation of policy programmes such as monthly meetings should be reintroduced and creation of CSA Departments/Stations in each state; increased budget allocation to a minimum of 10% for agriculture, revitalisation of Researchers-Extension Agents-Farmers Linkage, employment of qualified extension agents and retraining of extension agents.

The purpose of this paper is to assess participants’ perception that tramadol enhances physical work performance and acts as a pain relief.

The participants were 30 (18 male and 12 female) tramadol-using emerging adults, aged 16–27 years, selected through respondent-driven sampling. The majority of the participants were university students, whereas others had completed senior secondary education. The study adopted a qualitative design. Qualitative data were analysed using thematic analyses.

In general, respondents perceived and used tramadol for pain relief and physical work performance enhancement. The result showed that sex, employment status and daily dosage were not associated with respondents’ perception of tramadol as a pain-relieving medication. In contrast, sex and employment status were associated with participants’ perception of tramadol as a physical work performance enhancement medication, but daily dosage was not.

Some users refused to participate because they were afraid of being exposed to law enforcement.

Male and female emerging adults are involved in non-medical use of tramadol. Prevention and intervention programs to reduce or stop this behaviour are needed, especially in the rural communities.

The result showed that users were mostly from poor homes, whose parents could not afford university education and who were not qualified to get good government paying jobs. So, the use of tramadol became necessary for them to make more money from the kind of jobs they did. Reduction of the cost of university education and provision of regular jobs for this population are some of the measures recommended to counter non-medical use of tramadol by this population.

This is the first study in South-eastern Nigeria that focused on the non-medical use of tramadol among emerging adults, using a qualitative design.

The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.

The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.

The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.

Funding was the main limitation.

Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.

This study aims to evaluate how audit committee (AC) characteristics affect the performance of banks in Africa.

The authors manually generated unbalanced panel data from 78 commercial banks operating in twelve (12) countries whose annual reports were published on the website of African Financials between 2010 and 2020.

The results indicate that AC size has an insignificant positive association with bank performance (return on equity and Tobin’s Q). AC independence has a significant positive association with bank performance. However, AC gender diversity has a significant negative association with bank performance. Besides, AC financial expertise has a significant positive and negative association with return on equity and Tobin’s Q, respectively.

The study considered only 78 banks that operate in twelve (12) African countries. Besides, the authors consider only four (4) AC attributes.

The findings suggest the need to maintain a smaller AC, appoint more independent members to AC, reduce the number of women appointed to AC and ensure most AC members have financial expertise. These measures could improve bank performance in Africa.

Unlike previous African studies that are mostly restricted to a country level, the study examined how AC attributes influence the performance of banks that operate in Africa.

The study builds on studies in online shopping. Existing studies in online shopping proved that it is an attraction to shoppers. In Nigeria's emerging economy the increasing Internet penetration does not equate with intention to use online shopping because it is not really used by users for online shopping. Consumers are considering it unattractive because of serious concerns that border on product quality of online shops and poor know-how on e-tech. The study sought to explore factors that could mitigate challenges to successful online shopping in Nigeria's emerging economy.

Online survey method was used to sample 246 respondents. Measurement items were adapted from related literature. Confirmatory factor analysis and content validity were used to check the reliability and validity. A set of fit indices were used to check the goodness of fit. Data was analysed using structural equation model.

Results indicate direct effects of consumer attitude, perceived usefulness and social influence on intention to use online shopping with consumer attitude shown to have a greater degree of importance towards intention to use online shopping. Thus, consumers' attitude of browsing online and going offline for purchases is dependent on attitude of like or dislike. Perceived ease of use, social influence and perceived usefulness had an indirect positive effect on consumer attitude to intention to use online shopping. Social influence is indicated to have a direct positive effect on perceived ease of use. Also perceived ease of use had a positive and direct effect on perceived usefulness.

The sample size is not large enough and the use of snowball sampling limits representativeness.

The study indicated vital factors African emerging economies like Nigeria can use to improve consumer confidence towards intention to use online shopping and drive cashless policies. Several studies have missed the indirect effect of referents (social influence) on adoption of technology. The study proved that it can produce indirect effect as well as direct effect on intention to use online shopping.
