The purpose of this paper is to decompose the inequities induced by the Nigerian health care financing sources and their effect on the income distribution. Inequities in health care financing sources are of immense policy concern particularly in developing countries such as Nigeria, where high-level income inequality exists, and the cost of medical care is generally financed out-of-pocket (OOP) due to limited access to health insurance.

The Duclos et al. decomposition model provided the theoretical framework for the study. Data were obtained from two waves of the Nigeria General Household Survey (GHS) panel, 2012–13 and 2015–16. The analysis covered 3,999 households in 2012–13 and 4,051 households in 2015–16. Two measures of health care financing: OOP payment and health insurance contribution (HIC) were used. The ability to pay measure was household consumption expenditure.

The major inequity issue induced by the OOP payments was vertical inequity. HICs created the problems of vertical inequity, horizontal inequity and reranking among households. Overall both health care financing options were associated with the worsening of income inequality both at the national and sectorial levels in the country. The operations of the NHIS need to be improved to ensuring improved health care coverage for the poor.

This paper fulfills an identified need to determine the income redistributive effects (REs) of the social health insurance (SHI) contribution at the national, urban and rural locations overtime.

The purpose of this paper is to examine the determinants of health expenditure at the household level in Nigeria with specific focus on the household and individual unique characteristics. It presents some stylised facts about the Nigerian health system and its financing options. It went further to show that household is the major financial organ of healthcare in Nigeria. The study aims to expand the domain of household health expenditure by analysing at national, urban and rural levels.

It adopted Engel curve approach, which was estimated using ordinary least squares technique. The model was structured to take care of life-cycle implications by examining effects of age in years and age groups (0-9, 10-19, 20-39, 40-59 and 60+) on healthcare spending. Data were drawn from the 2010 Harmonised Nigeria Living Standards Survey (HNLSS) conducted by the National Bureau of Statistics and analyses were conducted nationally, for urban and rural locations.

The result shows that individual characteristics like age, religion, education and household characteristics like income, size and headship commonly influence healthcare expenditure in Nigeria significantly. The household-level variables possess stronger significant effects among the rural households while marital status and employment had differential effects in both urban and rural locations. It also confirmed that Nigeria engages in intergenerational transfer of healthcare by the working population to the young and older generations.

HNLSS was only limited to those who were sick or injured in the last two weeks preceding the survey, leaving out those whose sickness preceded the two weeks before the survey. Also, the scope of health expenditure is limited to curative care spending that exclude expenses on preventive care, rehabilitative care as well as other cost-saving services.

This paper fulfils an identified need to examine the determinants of household health expenditure at the national, urban and rural locations.

The purpose of this paper is to estimate Nigeria's audiovisual services import demand using foreign football transmitted through digital satellite television (DSTV) as a case study. The major focus is on whether such imports effectively replace local recreation in watching domestic football.

The authors examined descriptive statistics. The methodology employed is a combination of descriptive analysis and cross‐sectional regression.

The paper's analytical framework establishes a link between the conventional import demand and demand for football functions, while the estimated empirical counterpart found that the demand for foreign football via cross‐border satellite transmission is a statistically significant function of taste for foreign football, quality, and entertainment. While descriptive statistics indicate respondents’ preference for foreign football, the test of significance rejected the hypothesis that the demand for foreign football broadcast service imports has replaced demand for domestic football as an entertaining sport. In addition, the demand for foreign football broadcast is fairly inelastic, as a greater percentage of the respondents will watch foreign football even if the cost of subscription or cost of paying per view in the viewing centers increase.

The paper describes the first of this type of research to be conducted in Nigeria.

The challenges confronting the Nigerian construction industry which led to the adoption of supply chain management (SCM) practice were evaluated in this chapter. It was discovered that the Nigerian construction industry is confronted with fragmentation and poor information management. The stakeholders within the Nigerian construction industry proposed the adoption of SCM to overcome the fragmentation and other shenanigans facing the industry. This chapter revealed that construction supply chain (CSC) practices within the Nigerian construction industry focus on waste elimination by adopting the lean concept. The focus on the lean concept could be attributed to the numerous research related to lean or the enormous waste emanating from the Nigerian construction industry. Regardless of the emphasis on lean, the Nigerian CSC is still confronted with fragmentation and heavy waste generation. Thus, this chapter proposed the adoption of principles and technologies driven by the fourth industrial revolution (4IR) is a paradigm shift for the management of CSC in the country. It was discovered in this chapter that Nigerian construction supply stakeholders had not embraced the technologies and principles of the 4IR. The failure to adopt the technologies driven by the 4IR is attributed to the absence of a CSC model that depicts the management of CSC in alignment with the 4IR. This chapter called for developing a SCM model for the Nigerian construction industry in tandem with the principles and technologies of the 4IR.

This paper aims to demonstrate the optimization of an existing residential building in a tropical climate using indigenous materials as an alternative to conventional building envelopes to achieve thermal comfort and affordable housing.

This study mainly adopted a quantitative research methodology through a comprehensive simulation study on a selected prototype building. The energy plus simulation tool in DesignBuilder was used to predict the average monthly and annual thermal comfort of a typical residential building in the study area. Also, a cost analysis of the final optimization interventions was conducted to estimate the construction cost savings.

The comparative analysis of simulation results for the base-case and optimized models indicates potential advantages in replacing conventional building envelope materials with indigenous materials. The base-case simulation results showed that the annual operative temperature is more than the adaptive thermal comfort set points in tropical climates, by 8.26%. This often leads to interventions using mechanical cooling systems, thus triggering overconsumption of energy and increase in CO₂ emissions. The building envelope materials for floor, walls and roof were replaced with low U-values indigenous materials until considerable results in terms of thermal comfort and overall building construction cost were achieved. The final simulation results showed that using indigenous materials for the ground floor, external walls and roof could substantially reduce the annual operative temperature by 8%, thereby increasing the predicted three months of thermal comfort in the base-case to nine months annually. Likewise, there was a 32.31%, 35.78% and 41.81% reduction in the annual CO₂ emissions, cooling loads and construction costs, respectively.

The knowledge of indigenous materials as an alternative to conventional materials for sustainable buildings is not new. However, most of the available research is focused on achieving affordable housing. There is a dearth of research showing the extent that these indigenous materials can be used to improve indoor thermal comfort in developing countries with tropical climates such as Nigeria.

The purpose of this paper is to re-examine the determinants of bank profitability in Nigeria. Specifically, the study investigates the effect of managerial cost efficiency on bank profitability. Also, since there exist mixed results and controversies in the literature, in both developed and developing countries, regarding the effect of efficiency on bank profitability, this study employs the standard measure of efficiency. In addition, the work incorporates the role of persistence, which is often neglected in the literature in developing countries.

This study employs system generalized method of moments.

The findings, using the case of Nigeria, show that cost efficiency is a strong determinant of bank profitability in developing countries. In addition, the profitability of banks in Nigeria persists over time; hence, the industry is fairly competitive.

The recent policies of banking industry recapitalization meant to increase profitability and stability in Nigeria and other African countries’ banking industry will not be effective if the issue of managerial efficiency is not properly addressed.

Improving the banking managerial efficiency will positively reduce bad loans, hence leading to the stability in the banking system.

The authors introduce efficiency using standard measure of stochastic frontier analysis for its measurement. Also, this study introduces the role of persistence in the literature in developing countries.

Vietnam's construction technology (CT) adoption is low when compared to other countries with similar gross domestic product (GDP) per capita resulting in lesser productivity. The research objectives are: (1) To undertake an extensive literature review on CT adoption challenges; (2) To investigate CT adoption challenges unique to Vietnam's construction sector; and (3) To propose data-driven solutions for a greater rate of CT adoption.

A two-stage descriptive survey method was adopted in alignment with the research aim and objectives. Based on the literature review of 215 articles, a questionnaire was designed and administered to experienced construction managers (CM) to identify whether CT has been adopted, barriers to adoption, drivers, and the most popular CT tools. Descriptive statistics were used to summarize the characteristics of interest in the empirical dataset and SPSS-based inferential statistics to estimate the means, frequency counts, variance and test hypotheses that informed the drawing of conclusions concerning the research objectives.

The popular CT tools identified were Autodesk, Microsoft Office and Primavera. The most influential CT adoption barriers: (1) Unknow`n impact on productivity, (2) Late implementation of software in construction projects, (3) Lack of understanding of importance and needs in the construction industry (4) Lack of funds during budget planning for technological advances and implementation (5) Lack of experts required for technological change, and insufficient skills in the industry.

It is expected that the findings could inform data-driven regulatory and practice reforms targeted at increasing greater uptake of CT in Vietnam with potential for replication in countries facing similar adoption challenges.

The findings are intended to support data-driven regulatory and practice improvements aimed at improving CT adoption in Vietnam, with the possibility for replication in other countries facing comparable problems.

Corruption is a long-standing challenge in Nigeria. The country’s development crises, including widespread poverty and insecurity, have direct and indirect links to corruption. The paradox of corruption in Nigeria is that political elites have politicised its elimination: while preaching anti-corruption, they are still neck-deep in corrupt practices. The purpose of this study centres on Nigeria’s anti-corruption crusade in the context of its effectiveness in attracting global support for external loot recovery. A related preoccupation of this study is to unravel the extent to which Nigeria’s anti-corruption accomplishments or otherwise have shaped international perception.

This study adopts a qualitative research design. It draws from primary data generated from 25 key informant interviews and complemented with secondary data from archival materials to examine Nigeria’s anti-corruption crusade, especially global perception and its overall implication in motorising the country’s quest for external loot recovery. It deploys unstructured interview guide to generate data from the key informants.

This study unveils three interrelated issues: since 1999, the promise of eliminating corruption from Nigeria’s body politic has been a recurring campaign theme without corresponding credible action against it. Although anti-corruption agencies exist in Nigeria, the country’s corruption profile is high, an indication of their ineffectiveness. The persistence of corruption has resulted in poor national image, thereby shaping negative international perception about Nigeria. The politicisation of Nigeria’s anti-corruption crusade has undermined international support and created uncertainty in the country’s quest for the recovery of its looted national funds.

The negative perception of the international community about the commitment of the Nigerian Government in fighting corruption has negative implications on the strategic partnership necessary for loot recovery across the globe.

The overall social implication is loss of global support for Nigeria’s anti-corruption drive, including its quest to recover its stolen national assets and other forms of international assistance for national development.

The value of this study is two-fold, one, its recency and originality in terms of interrogating the interconnections between domestic efforts at anti-corruption and global perception of such efforts; and two, the contextualisation of the compromised efficiency of Nigeria’s anti-graft agenda and its overall implications in securing global support for external loot recovery.
