Abstract

Purpose

Apart from providing theoretical clarity, the present research aims to validate empirically that the EPU will be adversely affecting these key macroeconomic variables and that managing EPU matters for economic policymaking in Nigeria.

Design/methodology/approach

A dynamic autoregressive distributed lag regression model is employed to analyse the relationship from 1990 to 2020. Based on the theory of multiplier effect, the analysis could examine the positive and negative changes in policy uncertainty, as well as the reliability in macroeconomic activities such as unemployment, infrastructure development and foreign direct investment inflows.

Findings

The findings revealed EPU is cointegrated with the key economic variables in focus. Further, the negative impact of EPU on corporate investment in FDI and positive impact of EPU on unemployment confirm for both short and long-run. However, the impact of EPU on government investment in infrastructure development is found to be positive which does not confirm the expected hypothesis.

Practical implications

Dynamic relationship between policy uncertainty and macroeconomic activities in Nigeria seems to exist. Taking risky decisions has impact and causing a high unemployment rate, poor infrastructural development and lower foreign direct investment inflows in the country.

Originality/value

Policy uncertainty in Nigeria is determining. Despite that, very little research found that rising uncertainty issues may significantly affect unemployment, investment in infrastructure and foreign direct investment inflows adversely. Therefore, policy uncertainty is an open space for economic activities to thrive in Nigeria, especially unemployment.

Abstract

Purpose

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

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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

Practical implications

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.

Originality/value

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.

Abstract

Purpose

BIM has much potential to improve the effectiveness of construction works with respect to design, construction and maintenance. However, many Architecture, Engineering, and Construction (AEC) firms are still lagging in the adoption and implementation of BIM in both developing and developed countries. The purpose of this study is to assess the barriers to BIM implementation, and examine the ways forward to improve BIM adoption within the Nigerian AEC firms.

Design/methodology/approach

A comprehensive literature review and questionnaire survey were used in the study. The survey targeted four different AEC firms. These include architectural firms, facility management firms, quantity surveying firms and structural engineering firms in Lagos, Nigeria. The data obtained were analyzed using mean score, standard deviation, Kruskal–Wallis test, and factor analysis.

Findings

The study identified 20 barriers to BIM implementation and identified ten ways forward to improve BIM adoption in AEC firms, particularly in Nigeria. The relative importance of both the identified barriers and the ways forward were gauged. The Kruskal–Wallis tests revealed that except for one (out of 20) identified barriers, and one (out of 10) identified ways forward; there is no statistical significant difference in the perceptions of four different AEC firms. The factor analysis result grouped the 20 identified barriers into three major factors to include: weak top management support and BIM environment related issues; cost of BIM software and training issues; and incompatibility, legal, contractual, and culture related issues.

Practical implications

The significance of the study cannot be over-emphasized due to BIM relevance to construction stakeholders and researchers at large.

Originality/value

The study findings would inform the decisions of the construction stakeholders to make some policy recommendations capable of positively influencing the full BIM implementation in AEC firms.

Abstract

Purpose

The purpose of this paper is to identify and assess the perceptions of constructional professionals on barriers to implementation of building information modeling (BIM) within the Nigerian construction industry.

Design/methodology/approach

A scoping literature review was conducted to identify the fourteen barriers to implementation of BIM, which were employed to design a questionnaire survey. Data collected were analyzed using descriptive statistics, mean score, Kruskal–Wallis test, analysis of variance and multivariate techniques such as factor analysis.

Findings

The descriptive and empirical analysis demonstrated a disparity of ranking of the 14 barriers factors among the groups; however no statistically significant differences among the 14 barriers to BIM. Based on the mean score ranking results, only three (out of 14) barriers are identified as critical (mean score greater than 3.5): few studies available on BIM and lack of knowledge, inexistence or inadequate government policies, and high cost of implementation. The results of the one-sample t-tests show that they were statistically significant differences in 10 out of 14 barriers as follows: few studies available on BIM and lack of knowledge, lack of demand for use and acceptance of BIM, inadequate contractual coordination, lack of specified standards, cost of data and information sharing, technological availability issues, reluctance of other stakeholders, business and cultural changes, data and intellectual property issues, and interoperability issues. The study, through factor analysis, categorized the fourteen barriers to BIM implementation into four principal factors. The factors are: technology and business-related barriers; training and people-related barriers; cost and standards-related barriers; and process and economic-related barriers.

Practical implications

The identification and assessment of the key barriers to BIM implementation would be useful for the construction professionals and other stakeholder of the construction industry with the view to advance BIM adoption in Nigeria. This could also be extended to other developing countries through considerations of the local economic conditions, given the status of BIM as being in the germinating stage of development in Africa.

Originality/value

The study provides insights on the barriers to BIM implementation across the Nigerian construction sector environments. The innovative aspect of the study is the identification of the ordered and grouped (composite) set of barriers to BIM which could be used to developing appropriate mitigating solutions.

Abstract

Purpose

The purpose of this paper is to propose a model that will demonstrate how the integration of Salam (exclusive agricultural commodity trade) with Takaful (micro-Takaful – a subdivision of Islamic insurance) and value chain can address major challenges facing the agricultural sector in Kano State, Nigeria.

Design/methodology/approach

The study conducted a thorough and critical analysis of relevant literature and existing models of financing agriculture in Nigeria to come up with the proposed model.

Findings

The findings indicate that measures undertaken to address the major challenges fail. In view of this, this study proposed Bay-Salam with Takaful and value chain model to solve a number of challenges such as poor access to financing, poor marketing and pricing, delay, collateral requirement and risk issues in order to avail farmers with easy access to finance and provide effective security to financial institutions.

Research limitations/implications

The paper is limited to using secondary data. Therefore, empirical investigation can be carried out to strengthen the validation of the model.

Practical implications

The study outcome seeks to improve the productivity of the farmers through enhancing their access to finance. This will increase their level of production and provide more employment opportunities. In addition, it will boost financial inclusion, income generation, poverty alleviation, standard of living, food security and overall economic growth and development.

Originality/value

The novelty of this study lies in the integration of classical Bay-Salam with Takaful and value chain and create a unique model structure which the researchers do not come across in any research that presented it in Nigeria.
