This study investigates the impact of total health expenditure on life expectancy in a panel of 43 African countries from 2000 to 2018.

Abstract

Purpose

This study investigates the impact of total health expenditure on life expectancy in a panel of 43 African countries from 2000 to 2018.

Design/methodology/approach

The dynamic panel generalized method of moments (GMM) estimation method developed by Arellano and Bond (1991) is used in this study. This approach generates estimates that are heteroskedasticity and autocorrelation consistent, as well as controls for unobserved time-invariant country-specific effects and eliminates any endogeneity in the panel model.

Findings

The results reveal that health expenditure on its own has a positive significant influence on life expectancy. However, health expenditure via the moderating effect of government effectiveness reduces life expectancy. The authors also observe that school enrollment and the level of economic activity significantly drive life expectancy.

Research limitations/implications

The study is limited to 43 out of 54 African countries, and it covers a period of 18 years: 2000 to 2018.

Practical implications

The authors argue that larger health expenditure will aid in improving the life expectancy rate in Africa. However, in practice, this would be difficult given the needs of other priority sectors.

Social implications

Since most developing countries' health expenditures are small, a policy option is that healthcare services should be subsidized such that the poorest people can also access them.

Originality/value

The study differs from the previous attempts, and with this, the authors contribute significantly to the literature. First, to the best of the authors’ knowledge, the authors are unaware of any study considering the role of government effectiveness as a moderating factor in investigating the effect of health expenditure on life expectancy in the African context. Thus, the authors fill a yawning gap in the literature. Second, the authors employ a recent dataset with larger sample size. Finally, to address the problem of endogeneity and simultaneity bias, the authors use the system GMM technique.

This study seeks to empirically examine the influence of corporate governance on corporate performance in Ghana.

Abstract

Purpose

This study seeks to empirically examine the influence of corporate governance on corporate performance in Ghana.

Design/methodology/approach

The study employs data from 30 listed firms spanning from 2008 to 2018 and applies the generalized method of moments technique. The authors use economic value added, shareholder value added (SVA) and economic margin (EM) as measures of corporate performance.

Findings

The findings reveal that the presence of both inside directors and outside (nonexecutive) directors significantly improves corporate performance, lending credence to both the stewardship theory and the agency theory. The inclusion of women on the corporate boards and frequent meetings of the board reduce the economic profits of firms. The authors find that CEO duality impedes corporate performance, supporting the presumption of the agency theory. The study further reveals that audit committee size and ownership concentration positively drive the performance of quoted firms in Ghana.

Originality/value

Prior studies on corporate governance and firm performance nexus have chiefly adopted traditional accounting-based performance measures such as return on assets and return on equity to evaluate firm performance. However, these indicators are critiqued for being historic and fail to consider firms' cost of equity. In light of the shortcomings of the accounting-based proxies, this study takes a unique direction by using value-based metrics, which are considered superior measures of performance. Besides, to the best of the authors' knowledge, this study provides a first attempt to investigate the link between corporate governance and firm performance using SVA and EM as performance indicators.

This study aims to examine the impact of economic globalization on bank profitability in Sub-Saharan Africa.

Abstract

Purpose

This study aims to examine the impact of economic globalization on bank profitability in Sub-Saharan Africa.

Design/methodology/approach

The empirical analysis is based on panel data of banks spanning 2008–2016. Relying on the KOF Globalization Index, the study uses financial globalization and trade globalization as measures of economic globalization. The authors employ the system generalized method of moments technique to establish the relationship between economic globalization and bank profitability while controlling for the effect of bank-specific and macroeconomic factors.

Findings

The results show a negative significant effect of financial and trade globalization on bank profitability, signifying the intense competition of banks in Sub-Saharan Africa accelerated by globalization. The negative effect of economic globalization holds irrespective of the indicator of bank profitability. Bank size exerts a significant effect on profitability though the impact is negative for return on equity measure. The findings further reveal a positive significant impact of GDP growth and inflation on profitability.

Originality/value

This paper presents a pioneering work on the impact of economic globalization on bank profitability in the Sub-Saharan African context per the researchers' knowledge.

The study investigates the impact of information and communications technology (ICT) and financial development on tourism development in Ghana.

Abstract

Purpose

The study investigates the impact of information and communications technology (ICT) and financial development on tourism development in Ghana.

Design/methodology/approach

The researchers employ data covering from 1995Q1 to 2020Q4 and apply the autoregressive distributed lag (ARDL) estimation technique.

Findings

The findings reveal that ICT exerts a positive significant impact on tourism development in both long- and short-term periods. The authors find that financial development has a negative significant effect on tourism development in the long run. However, financial development significantly increases tourism revenue in the short term. The results further reveal a significant positive link between infrastructure development and tourism receipts in the long run.

Originality/value

This study is a pioneering effort to investigate the impact of ICT and financial development on tourism development in Ghana, as far as the researchers are aware. Additionally, the use of an index of ICT adds novelty to the literature. In terms of policy, the findings of this study can inform policymakers on the importance of investing in ICT and financial development to boost the tourism industry in Ghana.

Abstract

Purpose

This paper seeks to provide empirical insight into how industrialization and technology affect environmental quality in Ghana.

Design/methodology/approach

Using Ecological Footprint (ECF) as a measure of environmental degradation, the authors employ annual data from World Development Indicators of the World Bank and the Global Footprint Network spanning from 1970 to 2017 and apply the fully modified least squares (FMOLS) technique.

Findings

The results reveal that industrialization has a negative significant influence on ECF, suggesting that industrialization contributes to environmental sustainability in Ghana. The authors find that technology is harmful to the environment as it has a positive significant effect on ECF. The study also documents that while education and financial development improve environmental sustainability, fossil fuel consumption exacerbates environmental degradation in Ghana.

Originality/value

The environmental impact of industrialization is still being debated, with very scanty empirical evidence in the African context. Based on a detailed review of the literature, this paper provides an initial attempt to investigate the industrialization–environmental sustainability nexus in Ghana. Besides, whereas most extant studies have employed CO2 emission as a proxy of environmental degradation, the authors use ECF to gauge the level of environmental degradation which is regarded as a more inclusive metric.

This study aims to explore the impact of environmental sustainability on government health expenditure in Africa for the period 2000–2021.

Abstract

Purpose

This study aims to explore the impact of environmental sustainability on government health expenditure in Africa for the period 2000–2021.

Design/methodology/approach

The study employs the generalized method of moments (GMM) technique and utilizes a sample of 43 African countries.

Findings

The study reveals that carbon dioxide (CO2) emissions and renewable energy consumption have a positive relationship with health expenditure. For the control factors, we demonstrate that economic growth, urbanization and industrialization have a significant negative influence on health expenditure, while the impact of education on health expenditure is positive.

Practical implications

The study proposes several policy recommendations, including prioritizing investment in renewable energy sources and promoting the use of cleaner energy sources such as wind, solar and hydroelectric power. These measures would help improve environmental quality and reduce government health expenditure.

Originality/value

The study contributes to the limited research on the relationship between environmental quality and health expenditure in Africa. Moreover, it goes beyond previous studies that only considered CO2 emissions and explores the impact of adopting cleaner energy sources on health expenditure.

This paper aims to investigate the impact of institutional quality on foreign direct investment (FDI) in Ghana for the period 1985-2016.

Abstract

Purpose

This paper aims to investigate the impact of institutional quality on foreign direct investment (FDI) in Ghana for the period 1985-2016.

Design/methodology/approach

The study uses the autoregressive distributed lag (ARDL) approach to examine the relationship between institutional quality along with other controlled variables and FDI.

Findings

Evidence from the ARDL framework establishes a positive significant effect of institutional quality on FDI irrespective of the time horizon. The results also reveal a significant impact of inflation on FDI in both short and long run, while GDP per capita growth and trade are significant determinants only in the short run.

Practical implications

The study recommends the instigation of effective policies and strategies that seek to strengthen the quality of institutions, as this provides a conducive investment climate to attract FDI. Specifically, policies that are focused on promoting transparent legal regimes, regulatory reforms, non-corrupt institutions and political stability should be the precedence of policymakers.

Originality/value

In addition to being a pioneering work on the impact of institutional quality on FDI in Ghana, the main contribution of the study lies in its application of the principal component analysis to generate a single measure of institutional quality based on a number of institutional factors.

Abstract

Purpose

This paper aims to examine the key factors determining bank deposit growth in Turkey for the period 2000Q1–2016Q4.

Design/methodology/approach

The study employs the autoregressive distributed lag approach to investigate the effect of bank-level and macroeconomic factors on deposit growth.

Findings

The results reveal that bank stability, banking sector efficiency, broad money supply, economic growth, and inflation are significant determinants of deposit growth in the long run. The findings further show that in the short run, only branch expansion and broad money supply are relevant for bank deposit mobilization.

Originality/value

This paper departs from the extant empirical studies that focus on the determinants of individual savings behaviour in Turkey. Considering the short- and long-run time dimensions, the authors distinctively examine how bank characteristics influence deposit growth, thus presenting a relatively pioneering attempt in this context.

Abstract

Purpose

This study seeks to investigate the impact of financial intermediation on economic growth in Turkey using annual data spanning 1970–2017.

Design/methodology/approach

Based on the results of the augmented Dickey–Fuller and Phillips–Perron unit root tests for stationarity, the authors employ the Autoregressive Distributed Lag (ARDL) bounds testing to cointegration to establish the long-run impact of financial intermediation alongside other control factors on economic growth. The study also examines the short-run relationship between financial intermediation and economic growth by estimating the Error Correction Model (ECM).

Findings

The authors’ findings indicate that financial intermediation significantly influences economic growth in both short and long run. However, the effect is positive only in the short run, lending support to the supply-leading hypothesis. Regarding the control variables, the authors observe that while financial openness shows a positive significant impact on economic growth in the long run, gross fixed capital formation matters only in the short run. The results further infer that regardless of the time period, inflation impedes economic growth.

Originality/value

In the empirical analysis of the relationship between financial intermediation and economic growth, financial intermediation is always measured using a single variable. The authors argue that such studies could produce bias and misleading results given that a single proxy does not adequately reflect financial intermediation activities. Likewise, such findings may delude policy implementation. To provide a more vivid and robust analysis, the authors employ the Principal Component Analysis (PCA) to construct a composite index for financial intermediation based on three broad measures. The researchers’ are unaware of any study on the financial intermediation–economic growth nexus using a composite index of financial intermediation. Thus, this paper fills this lacuna in the literature.

Abstract

Purpose

The purpose of this study is to investigate the effect of financial intermediation functions of banks on economic growth in sub-Saharan Africa.

Design/methodology/approach

The study employs data from 11 sub-Saharan African countries over the period 1970–2016. Using broad money supply, bank credit to the private sector and bank deposits as financial intermediation measures, the authors apply the random effects (RE) technique based on the recommendation of the Breusch–Pagan test.

Findings

The results show that except for bank deposits, broad money supply and bank credit to the private sector significantly influence economic growth. While broad money has a negative relationship with growth, bank credit to the private sector and bank deposits are positively correlated with economic growth.

Originality/value

The relationship between financial intermediation and economic growth remains unsettled, as results vary across countries. Besides, in developing countries' perspective, extant studies are largely focused on individual countries to investigate the financial intermediation-growth nexus. In this study, the authors take a different direction by employing a panel approach and thus adding to the few cross-country studies on the subject matter. Also, unlike other studies that have focused on a single indicator of financial intermediation, this study uses three indicators of financial intermediation which broadly reflect the intermediation functions of banks.
