This study aims to investigate the effect of income and asset diversification on earnings management using discretionary loan loss provisions (LLP) in banks, and the role of risk level in mediating this effect.

A sample of banks operating in Middle East and North Africa countries was used to test the mediation model of Baron and Kenny (1986) with different measures of diversification and risk.

The results show that bank income and asset diversification have unique and combined effects on earnings management. The results also support the idea that a risk-mediating effect contributes to explaining this relationship among banks. Specifically, bank diversification strategies positively affect LLP-based earnings management by increasing bank risk. This result is relevant for conventional banks. However, only a direct and positive effect of diversification strategies on LLP-based earnings management can be observed in Islamic banks, and the indirect effect is not supported.

This study extends previous research by examining the unique and combined effects of income and asset diversification strategies on earnings management in the banking sector. Specifically, it provides new evidence that diversification strategies increase LLP-based earnings management, both directly and indirectly, through bank risk.

This study examines whether income diversification moderates the relationship between intellectual capital and bank performance among East African banks.

The study uses a sample of 53 East African banks and a panel dataset for the period 2010–2018. The hypotheses are tested through a hierarchical regression model.

The regression results indicate that intellectual capital (IC) significantly affects bank performance. Further, the study finds that income diversification has a negative and significant effect on bank performance. The results indicate that income diversification reduced the overall impact of IC (Value Added Intellectual Capital (VAIC)) efficiency on bank performance for the moderating influence. However, the moderating role of income diversification on the relationship between individual components of VAIC (HCE, SCE and CEE) varies. While income diversification enhanced the impact of structural capital efficiency (SCE) on bank performance, it also reduced the effect of human capital efficiency (HCE). Additionally, income diversification did not moderate the impact of capital employed efficiency (CEE) on bank performance.

This study contributes to the literature by demonstrating that non-traditional banking activities influence the IC and bank performance relationship, which is scanty in the existing literature.

This paper aims to empirically investigate the impact of bank diversification on performance and risk-taking behavior. The analysis uses an unbalanced panel data set covering the period between 2007 and 2015 for a total of 1,397 banks from ASEAN-5 and BRICS economies.

Dynamic panel generalized method of moments (GMM) has been used primarily to examine the relationship between bank diversification on performance and risk-taking and later, validate the core results by incorporating two-stage least squares (2SLS).

Similar to the results of previous studies based on the developed economy, this study also confirms the hypothesis of the portfolio diversification. The key robust result is that the benefits from revenue and assets diversification are heterogeneous and the BRICS banks achieve higher benefit from using both diversification strategies. On the other hand, ASEAN-5 banks fail to show the significant advantage from assets diversification. Among the diverse sources of income, interest is not a major determinant of efficiency and bank’s stability, while ASEAN-5 banks should foster commission and others income as mechanisms for diversification benefit in the region.

A few studies are available in the current literature which examines the impact of revenue and assets diversification on either bank performance or risk-taking in the developed economy’s context. However, very few studies are found that examine the relationship between bank diversification, performance and risk-taking together. Moreover, to the best of the author’s knowledge, there is a dearth of literature on this topic that built on the comparative analysis between two regions, i.e. ASEAN-5 and BRICS. As a result, the empirical results of this research provide useful information to the stakeholders so that they can enhance bank diversification strategy and implement them successfully by considering the other factors.

The purpose of this paper is to investigate the effect of revenue diversification, non-interest income and asset diversification on the performance and stability of the Gulf Cooperation Council (GCC) conventional and Islamic banking systems.

The authors implement a panel of 69 conventional and Islamic banks listed in six GCC markets over the period of 2003–2015, using the System Generalized Method of Moments methodology.

Non-interest income diversification has a negative impact on GCC banks’ performance, while asset-based diversification affects banks performance positively. However, Investors tend to penalize the value of the banks’ assets, which are highly diversified. Government intervention, lack of competition, legal protection and high control of Central banks on GCC banks’ have positive impact on performance. Contrary to the results on conventional banks, asset diversification adds value to Islamic banks. Overall, both banks’ revenue and non-interest diversification have negative impact on GCC banks’ stability, while asset diversification improves Islamic banks’ stability.

The analysis is limited to a sample of banks, which are listed in the GCC stock exchanges. The lack of data on private and foreign banks operating in the region made the analysis and, consequently, the results specific to shareholding companies. Also, the authors’ measures of bank stability might not be appropriate to use for Islamic banks, given their banking models implemented.

Research results provide important implications for regulators, bank managers and policy makers, as to the expected ways to support economic diversification through bank diversification strategies.

Unlike related studies, the authors’ sample of homogeneous banks has a market structure that is different from the samples in the literature covering either developed countries or heterogeneous samples from both developed and developing countries. Furthermore, using an efficient econometric methodology, the authors deal with two types of banks: conventional banks and Islamic banks. The research determines which type of bank is more able to benefit from different types of diversification. Unlike previous research, this research explores the sensitivity of the results both to the regulatory environment of the GCC market and to general market conditions.

This study explores the effect of income diversification strategy on credit risk and market risk of microfinance institutions (MFIs) in Ghana as an emerging market.

The study is based on quarterly data of averagely 271 MFIs that have operated from 2016 to 2018. The dataset is unbalanced and pooled cross-sectional with 3,259 data points. The study measures the diversification strategy using income diversification indices, and accounting ratios to measure the other variables. We utilised the weighted least squares (WLS) approach to explore the nexus.

The findings show that income diversification is associated with better loan quality and credit risk management. Market risk increases with the level of income diversification of microfinance firms. It is evident that large MFIs can manage their credit risks well and can have a low default rate, depicting an overall U-shaped nexus. On the other hand, the effect of size on market risk is an inverted U-shaped. The effect of asset tangibility on credit risk is positively significant while the effect on market risk is negatively significant. High profitability enhances credit risk management leading to lower loan losses while in the case of diversified and profitable MFIs, they tend to invest more in government securities. The results suggest that MFIs that hold more cash and cash equivalents tend to have high loan loss provision and more government securities suggesting much attention should be paid to optimal cash management.

The results throw light on the credit risk and market risk profile of the firms and the effect of diversification strategies on them. The findings are relevant for effective macroprudential regulation, market regulation and prudential regulation of the microfinance sector.

The findings reveal the nature of income diversification strategy of MFIs in emerging markets such as Ghana, pointing out how they affect the risk exposure of MFIs that lend to the pro-poor population.

This is a premier formal assessment of the nexus between income diversification strategies and risk management among MFIs that serve the pro-poor population in the emerging market context.

The purpose of this paper is to examine whether income diversification moderates the relationship between human capital and bank performance.

The study uses a sample of 53 banks and panel data for the years 2010–2018. The hypotheses are tested through hierarchical multiple regression and the choice between fixed effect and random effect estimation is based on the results of the Hausman test.

The study finds that human capital and income diversification significantly influence bank performance; however, the direction of the causality varies. While human capital has a positive effect, income diversification has a negative effect. Additionally, the interaction term has a negative and significant effect on bank performance, inferring that income diversification has an antagonistic effect on the human capital and bank performance relationship. For the control variable, liquidity and asset quality negatively affects bank performance while capitalization has a positive effect.

Human capital was measured as human capital efficiency (HCE), which is a quantitative measure of human capital, hence future studies can use qualitative measures. Also, the study focused on commercial banks in East Africa, future researcher may possibly consider other regions and industries, which would shed more insights.

The results of this paper provide valuable insights. Bank managers can get a better understanding of the impact of human capital on bank performance, and the need to invest more in human capital development. Further, the study cautions bank managers that engaging in non-lending activities might destroy the economic value of human capital and ultimately lower performance. The study also recommends that policymakers should address the obstacles to banks' income diversification, for instance relaxing regulations restricting diversification; this might enable banks to leverage related financial service activities for optimal utilization of human capital and improve banks' profitability.

While a good number of previous studies investigated the direct effect of human capital and income diversification on the performance of banks, this study examines the moderating role of income diversification on the relationship between human capital and performance of banks in East Africa.

This study investigates implications of crop and income diversifications on consumption expenditure (welfare) of rice-producing households in Ghana. It further compares diversification by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production.

Primary data were sourced from 225 rice farmers. Margalef index and three-stage least-squares were employed.

Majority of rice-farming households in Ghana diversify livelihoods. The extent of livelihood diversification differs among two-season rain-fed, two-season irrigated and one-season rain-fed rice-producing households. Credit, distance to district capitals, production purpose and number of farming seasons influence crop and income diversifications, and consumption expenditure of rice-producing households. While crop diversification reduces consumption expenditure, income diversification increases it. Crop and income diversifications positively influence each other. Consumption expenditure reduces crop diversification but increases income diversification.

Policy should be directed towards the promotion of more livelihood activities to boost rice farmers' welfare. There should be awareness creation and training programmes to enable rice farmers realize different economic activities within and outside the agricultural value chain.

Crop and income diversifications were measured as continuous response variables, unlike previous studies that used a binary response variable. The authors established a synergy among crop and income diversifications, and consumption expenditure (welfare). The authors further compared crop and income diversifications by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production systems.

This paper aims to conduct a comparative study on the impact of income diversification and the main non-interest components on banks’ financial performance and risk-adjusted profitability in China and Egypt.

This study uses both static and dynamic panel regression analyses on a sample of Egyptian and Chinese banks from 2009 to 2022.

Income diversification yields positive effects on bank profitability in Egypt and China. Trading income consistently exhibits a significant positive influence on bank profitability in both nations. Conversely, fee-based income positively impacts bank profitability in China, whereas in Egypt, this effect is observed under dynamic-based regression models. On the contrary, income diversification does not consistently increase risk-adjusted profitability in both countries, especially Egypt.

To the best of the authors’ knowledge, this is the first study to examine the impact of income diversification on Egyptian bank performance while identifying the most significant non-interest income components. In addition, the comparative analysis conducted in this study reveals the positioning of China, the largest economy among emerging countries, in terms of the degree of income diversification, its impact on bank profitability and the extent to which non-interest income components contribute to bank profitability when compared with Egypt, representing an emerging country characterised by different levels of bank market power, financial infrastructure and expertise. Findings hold significant implications, suggesting that bank managers and policymakers should prioritise diversifying income sources, particularly through fee-based services and trading activities in China, and trading activities in Egypt, to enhance financial profitability.

The income structure of banks has undergone a notable change in recent decades; therefore, non-interest-based activities have gained much attention. This paper aims to examine the impact of income diversification on bank performance in Pakistan.

A balanced panel data set of 20 Pakistani commercial banks is used from 2007 to 2020. The random effect model is employed to test the relationship between income diversification and financial performance.

The empirical results indicate a significant positive impact of income diversification of banks on risk-adjusted returns on assets and equity. Moreover, while banks' risk-adjusted profit performance improves with the increase in bank size, equity ratio and loan ratio, it deteriorates with high credit risk and technology. However, geographical diversification does not explain financial performance in all the risk-adjusted return on equity models. Among the macroeconomic factors, the interest rate influences bank risk-adjusted returns positively, whereas gross domestic product and inflation rate have a negative effect on banks' financial performance.

To the best of the author's knowledge, this study is the first to empirically investigate the relationships between income diversification and the risk-adjusted profits of Pakistani-listed commercial banks. This study has implications for regulators and policymakers of commercial banks.

This study aims to explore the determinants (bank-specific, industry-specific and macroeconomic) of income diversification across interest income and non-interest income as well as for non-traditional income sources (non-interest income) from 2004–2005 to 2021–2022.

An unbalanced data set comprising 110 Indian commercial banks with 1480 observations is sampled in this study. Because of the bounded nature of the dependent variables (proxies of income diversification), the panel Tobit regression model is used.

The findings reveal that income diversification is positively influenced by bank size, technological advancements, cost–income ratio, return on assets, market competition and inflation in the economy. However, the decision to diversify income sources is adversely impacted by the capital ratio, GDP and financial intermediation ratio. Moreover, factors such as asset quality (loan loss provisions) and liquidity ratio do not directly influence the diversification strategies in the Indian banking industry.

The present study uses an extensive set of variables to provide insights into key factors for bank managers, regulators and policymakers to consider before developing diversification strategies.

To the best of the authors’ knowledge, this is the first study to examine the various bank-specific and macroeconomic determinants that affect income diversification in the Indian banking sector. The current study also investigates new variables such as technological advancements and a market concentration index for measuring competition, which have not been investigated in existing literature concerning bank income diversification in the Indian context.
