Impact of Disaggregated External Debt on Economic Growth: Evidence from Asian Developing Economies

Abstract This study investigate the impact of total and disaggregated external debt on economic growth, across 32 Asian developing economies (ADE) from 1995 to 2020. The study applied the generalized method of moments (GMM) and dynamic common correlated estimator (DCCE) with interaction terms of institutional quality and macroeconomic policy to address the non-linearity, across-country heterogeneity, cross-sectional dependence and endogneity. The empirical results indicate that total external debt and its types initially harm economic growth, except for commercial creditors’ debt, which has positive effects. Short-term, private, and multilateral debt show weaker negative associations compared to long-term, public, and bilateral debt. Incorporating interaction terms in non-linear models reveal a shift from negative to positive impacts, highlighting the importance of robust institutional quality and stable macroeconomic policy in mitigating adverse debt effects. Our findings underline the necessity of tailored policies accounting for specific impacts of different debt types on economic growth. Moreover, highlight the significance of institutional quality and macroeconomic policy standards to manage risks, optimize debt management practices, adjust fiscal policies, and foster sustainable economic growth. Future research should further investigate the broad impact of domestic debt in conjunction with external debt across different countries, time periods, and methodological approaches.

The power of financial literacy: paving a clear path for the influence of board diversity on intellectual capital disclosure

PurposeUtilizing a multi-theoretical framework, this study aims to investigate the impact of board gender and nationality diversity on the extent of intellectual capital disclosure. Additionally, it seeks to explore the moderating role of financial literacy among audit committee members on the aforementioned relationship.Design/methodology/approachTo empirically test the study’s framework, a panel dataset of listed firms on the Palestine Stock Exchange (PEX) spanning 12 years (2010–2022) was utilized. To address potential endogeneity issues and ensure robust findings, a battery of econometric estimators was employed, including ordinary least squares (OLS), one-step system generalized method of moments (GMM), lagged independent variables and a sub-index model.FindingsThe study findings make a significant contribution to existing intellectual capital literature. Specifically, the results reveal that the positive influence of board gender and nationality diversity on the extent of corporate intellectual capital disclosure is stronger when there is a high proportion of audit committee financial literacy. Additionally, the study distinguishes between overall index and sub-index analyses. Interestingly, the findings from the sub-index analysis, focusing on structural capital, relational capital and human capital, are somewhat similar to the results of the full index analysis.Originality/valueTo the best of the authors’ knowledge, this study represents the first empirical attempt to uncover the impact of financial literacy among audit committee members on the relationship between board diversity and intellectual capital disclosure.

From petrodollars to green power: Fiscal stability and green transition in GCC economies

This study examines the influence of fiscal stability, characterized by fiscal buffers, on the green transition in the Gulf Cooperation Council (GCC) economies from 2005 to 2023. We apply two-way fixed effects, system generalized method of moments (GMM), method of moments quantile regression (MMQR), and panel causality analysis to explore these dynamics. Our findings underscore that a positive fiscal buffer resulting from a significant spread between oil prices and fiscal breakeven levels exerts a substantial positive impact on green transition efforts in GCC countries. The results reveal that countries with higher levels of renewable energy production capacity and urbanization demonstrate more pronounced advancements in green transition initiatives. Conversely, countries grappling with unstable macroeconomic conditions, such as high inflation and external debt, face considerable challenges in achieving significant improvements in green transition outcomes. Additionally, our analysis shows that fossil fuel energy fiscal subsidies negatively influence green transition efforts in the GCC region. Our study emphasizes that policymakers in GCC countries should pursue a dual-pronged strategy: leveraging positive fiscal buffers to diversify their economies in light of potential benefits from high oil prices, and channelling oil and fiscal revenues towards enhancing renewable energy production capacities. This approach aims not only to diversify economic foundations but also to strategically strengthen the infrastructure necessary for sustainable renewable energy transitions in the region over the long term.

Quantifying the spillover effects of U.S. economic policy uncertainty on emerging market economies using GMM-PVAR model

This paper quantifies the spillover effects of economic policy uncertainty (EPU) in the United States on emerging market economies (EMEs). Using a generalized method of moments (GMM) estimation of a panel vector autoregression (PVAR) model on a dataset­ of 39 EMEs from 2005 to 2019, we find that increased U.S. EPU significantly raises the consumer price index (CPI) and negatively impacts the real GDP of these economies. Additionally, heightened U.S. EPU leads to a depreciation of emerging market currencies and a reduction in short-term interest rates. We employ a news-based EPU index developed by Baker et al. (2016) and conduct robustness checks using forward orthogonal transformation, an alternative EPU index, and by addressing the potential endogeneity of the oil price uncertainty (OPU) index. Our findings highlight the adverse effects of U.S. economic policy uncertainty on key macroeconomic variables in emerging markets, underscoring the importance of stable economic policies and robust institutions to mitigate these impacts.

Does financial expertise influence Islamic bank risk-taking?

PurposeThis study investigated how the financial expertise of the board of directors, risk management committee (RMC), audit committee (AC) and Shariá Supervisory Board (SSB) influences the risk-taking of Islamic banks.Design/methodology/approachThe study utilized unbalanced panel data for a sample of 43 full-fledged Islamic banks from 15 countries over 12 years (2010–2021). We employed feasible generalized least squares (FGLS) and heteroskedastic panels corrected standard errors (HPCSE) regression regressions as the primary estimation methods and used a two-step system generalized method of moments (GMM) estimator for robustness checks.FindingsThe results indicate that board financial expertise decreases insolvency and credit risks. Similarly, AC financial expertise and SSB financial expertise reduce insolvency and portfolio risks but increase credit risk. In contrast, RMC financial expertise raises insolvency risk. The remaining relationships are statistically insignificant.Research limitations/implicationsDue to the lack of disclosure regarding the educational and professional background of the board and committee members in the annual reports of some Islamic banks, this research used a sample of only 43 full-fledged Islamic banks operating in fifteen countries from 2010 to 2021.Practical implicationsThe findings can assist both local and international regulators in revising corporate governance codes and risk management guidelines in such a way as to ensure that the financial experts appointed to the board, AC, RMC and SSB, are capable of controlling excessive risk-taking behavior in Islamic banks.Originality/valueThis study contributes to the literature by providing comprehensive empirical evidence that corporate governance financial expertise influences the risk-taking behavior of Islamic banks.

Horizontal and vertical foreign direct investment linkages, absorptive capacity and domestic investment: evidence from Indonesian plant-level data

PurposeThis study examines the effect of horizontal and vertical foreign direct investment (FDI) linkages on the investment decisions of domestic plants. It explores this link for plants in a developing country, where the dynamics of FDI spillovers on domestic investment choices are distinct from those in developed countries. It also adds to the literature by examining the role the absorptive capacity of plants plays in this nexus, enriching our understanding of the interaction between FDI and the investment choices of domestic plants and providing insights for policymakers and managers seeking to maximize the positive effects of FDI spillovers.Design/methodology/approachThis study specifies the dynamic investment equation using the Euler and Q models. This equation is estimated using the first-difference and system generalized method of moments GMM estimators, which allow us to address persistency, endogeneity and unobserved plant-specific effects. FDI exposure proxy, calculated by weighing the FDI engagement variable by firm size, captures the strength of foreign equity participation in an industry and time. Input–output (IO) tables are used to calculate the proxies for horizontal and vertical (backward and forward) FDI. Total factor productivity is calculated using a method advocated by Olley and Pakes (1996) that allows us to control for selection and simultaneity.FindingsWe find that FDI inflows into both the domestic plants’ own industry and the input-supplying industry significantly boost the capital accumulation of the average domestic plants. Differentiating plants based on their absorptive capacities reveals that the presence of foreign firms significantly increases capital deepening for domestic plants with high absorptive capacity within their own industry (horizontal linkage) and in industries that supply inputs to the FDI-exposed industry (backward linkage). However, it leads to a decrease in capital deepening for high absorptive capacity domestic plants in industries using inputs produced by the industry exposed to FDI (forward linkage).Research limitations/implicationsThese findings have implications for policymakers and managers who aim to design incentives to maximize the positive spillover effect of horizontal and vertical FDI linkages on the capital deepening of domestic plants. Exploring additional mechanisms that could play a role in this nexus, separately for plants in different industries (such as the industries in which the country has a comparative advantage), may be fruitful.Originality/valueTo our knowledge, the relationship between the investment behavior of the domestic plants and FDI linkages has not been examined for a developing country. It is useful to explore this link in developing countries, as the investment choices of plants in these nations may be impacted differently by FDI spillovers than those in advanced nations. This study further contributes to the literature by investigating whether the plants’ absorptive capacity affects the nexus between FDI linkages and investment decisions of the domestic plants. The findings are valuable for policymakers and managers who aim to increase plants’ capital accumulation in developing countries.

Determinants of MSMES’ credit access: Evidence from Indonesian banks

Credit is an important component in developing micro, small, and medium enterprises (MSMEs), as it can boost a country’s economy, help boost the production capacity of MSMEs, create jobs, and reduce poverty. This study aims to examine the characteristics of banks in Indonesia that influence lending to micro, small, and medium enterprises by adopting agency theory that explains the relationship between lenders (banks) and borrowers (MSMEs) as agents and principals. Data were taken from quarterly financial reports of banks in Indonesia. There are 42 sample banks from 2010 to 2022, so the data used are 2,182 observations. Data analysis uses a fixed effect model with robust standard errors. The results show that operating costs do not influence credit access for MSMEs or medium-sized enterprises. Bank stability has an impact on increasing MSME credit access. High bank capital also increases MSME credit access. Robustness tests were also conducted using the general method of moments. The results were consistent with the main model. The implication is that cost management theory and credit decision-making need to consider differences in business scale. The results also further strengthen the argument that bank stability is an important factor that can improve access to credit for small and medium enterprises.

Assessing the Impact of Federal Reserve Policies on Equity Market Valuations: An Instrumental Variables Approach

This study investigates the impact of Central Bank interventions on the pricing dynamics of select stock markets. The research utilizes the instrumental variables three-stage least square (3SLS) model approach. It analyses the effects of variations in the Federal Reserve’s balance sheet size across three distinct intervention scenarios: the 2008–2013 Great Recession, the 2020–2021 COVID-19 pandemic periods, and an overarching analysis spanning these timelines. Our methodology includes estimations of the Seemingly Unrelated Regression Equations (SURE), and the results are robust under the two-step Generalized Method of Moments (GMM). Our findings indicate that changes in the size of the Fed’s balance sheet correlate significantly with the pricing of principal U.S. equity market indices. This correlation reflects a time-dependent effect emanating from the Fed’s balance sheet expansion, marking a growing divergence between the adaptability of pricing mechanisms in equity and debt markets. Notably, the Federal Reserve’s interventions during the COVID-19 crisis are associated with an increase of approximately 0.0403 basis points per billion in treasury yields. This research makes a significant contribution to the understanding of financial asset pricing, particularly by elucidating the extent to which interventions in government debt securities engender price distortions in certain equity markets.

The Role of Reserves in Mitigating Sanctions’ Impact on Economic Growth

ABSTRACT As global risks mount, national reserves act as a nation’s frontline defense, guarding economic stability. This study investigates the role of national reserves in mitigating the impact of international sanctions on economic growth, analyzing 131 countries from 2000 to 2022. Using econometric methods, including two-step Generalized Method of Moments (GMM) and fixed effects models, we examine how reserves relative to external debt help buffer economies against sanctions. The findings show that economic sanctions significantly hinder growth, with trade sanctions being the most damaging. Reserves act as a key buffer, particularly in the short term, though their effectiveness decreases over time. Countries with stronger reserve adequacy are better equipped to manage the challenges of sanctions. The study highlights the importance of maintaining robust reserves and implementing broader strategies like economic diversification and structural reforms for long-term resilience. These insights are valuable for policymakers navigating sanctions-related economic challenges.

The Impact of Environmental Social Governance (ESG) on Firm Performance with the Moderating Role of CEO Turnover

This research aims to investigate the influence of Environmental, Social, and Governance (ESG) on firm performance, measured by Return on Equity (ROE). Additionally, the study explores the moderating role of CEO turnover in the relationship between ESG and firm performance in publicly listed companies on the Indonesia Stock Exchange, with a sample of 33 companies from 2016 to 2022. The GMM estimator method is employed to address endogeneity issues, ensuring consistent and unbiased estimation results. Findings indicate that overall ESG performance significantly affects firm performance, emphasizing the importance of implementing ESG principles in Indonesian businesses to enhance ROE. Other results reveal the pure moderating role of CEO turnover, weakening the relationship between ESG and firm performance. Therefore, proper planning and guidelines for CEO succession are crucial for improving firm performance and sustainability. The research results carry important implications for Indonesian companies to consider ESG implementation in their business strategies. Furthermore, CEO succession planning management is key to maximizing the positive impact of ESG on firm performance. This study contributes to a deeper understanding of how ESG factors influence firm performance in the Indonesian business context, highlighting the significance of executive leadership in managing these impacts.

Linder hypothesis and India’s services

This study examines the empirical validity of the Linder hypothesis for India’s service sector exports from 2005 to 2021, focusing on 35 major importing countries. We use a gravity model trade, applying Feasible Generalised Least Squares (FGLS) and two-step system generalised method of moments (GMM), incorporating country- and time-fixed effects. Our results confirm that the Linder hypothesis does not hold for Indian service exports, revealing an increase in trade intensity between countries with dissimilar income levels. The study finds that distance has a positive and significant impact on Indian service exports. Exchange rates have a negative and significant impact on India’s service exports, while the results for the RTA dummy variable are inconclusive. Sharing a common border, a common colony, and a language has a positive and significant effect on Indian service exports.

Does ICT Investment Affect Market Share and Customer Acquisition Cost? A Comparative Analysis of Domestic and Foreign Banks Operating in India

Competitive banks aggressively invest in information and communication technologies (ICT) to enhance their market share and reduce Customer Acquisition Costs (CAC). This study examines the impact of cumulative stock of ICT investment on (a) deposit and loan market share and (b) CAC of banks operating in India. The analysis uses a longitudinal dataset of 84 domestic and 70 foreign banks from 2000 to 2020, employing a two-step system Generalized Method of Moment (GMM). It is found that ICT investment adversely affects the market share of domestic banks, indicating a need for these banks to strategically invest more in CAC. Conversely, foreign banks are able to increase their market share through ICT investment and reduced CAC, thereby demonstrating greater efficiency in utilizing ICT. The study underscores the strategic importance of cumulative stock of ICT investment for banks. Nonetheless, it is emphasized that ICT investment must be complemented with innovative marketing strategies to enhance customer experience, reduce CAC, and increase market share. Overall, while foreign banks are able to leverage ICT to boost efficiency, domestic banks must leverage ICT to implement targeted marketing strategies and strive to enhance their customer service.

Do public governance and financial shocks effect public health? Empirical evidence from MENA region

Financial shocks have an incredible socioeconomic effect on both developed and developing countries. Various recent studies demonstrated that bad public governance impacted public health across all nations. In fact, this study aims to use panel data for 21 countries from the Middle East and North Africa (MENA) region over the period 2000–2020 to scrutinize the effect of both governance and financial crises on public health. We use the generalized method of moments (GMM) approach to carry out the empirical analysis. The objective of using this method is to deal with the issue of endogeneity between exogen variables. Results outline that there is a significant positive association between public governance indicators and public health. Moreover, we found a strong negative association between financial shocks and public health. Thus, the direct negative impact of financial crisis on public health could be mitigated by the indirect positive impacts via institutions and good public governance. This study gives insights to policymakers to take appropriate measures to decrease the severity of the financial shocks and improve healthcare services.

The development of the life insurance market and bank stability in developing countries

This study investigates the relationship between the development of the life insurance market and bank stability within the context of developing countries. We used data from 2012 to 2020 across 108 developing countries and applied econometric techniques, including fixed-effect and system generalized method of moments (GMM) methods, to test the relationship between the life insurance market size, life insurance market growth, and bank stability at the country level. Our results indicate a positive relationship between life insurance market size and bank stability, i.e., a large life insurance market can help increase bank stability in developing countries. However, these countries should refrain from developing their life insurance markets too quickly; according to our empirical results, there is an inverted U-shaped relationship between life insurance market growth and bank stability. In the context of the growing life insurance market in developing countries as well as the increasing cooperation between banks and insurance companies towards expanding the life insurance market in these countries, our research provides important policy implications for ensuring the stability for financial markets in general.

Does Green Finance Reduce Carbon Emissions? Global Evidence Based on System Generalized Method of Moments

Global environmental awareness has increased with the adoption of the sustainable development goals (SDGs) and the Paris Agreement. Global climate change has been a focal point in these international frameworks, with an emphasis on addressing environmental issues and setting specific targets for solutions. Financing plays a vital role in attaining goals established in international frameworks. The limitations of conventional finance have highlighted the need for green finance. There is a scarcity of studies in the literature examining the impact of green finance on carbon emissions, and a definitive conclusion has yet to be reached. This research aims to enhance the current literature by presenting empirical findings on how green finance influences carbon emissions globally. By employing the system generalized method of moments (GMM), developed by Arellano and Bover (1995) and Blundell and Bond (1998), this study investigated how green finance influences carbon emissions. Covering the span of 2017–2022, this study encompassed 48 countries across the globe. Green finance was found to have a negative and statistically significant impact on carbon emissions. Issuing green bonds to represent green finance, when increased by 1%, reduces carbon emissions by −0.012%.

Greenhouse gas assurance and carbon emission performance in light of the auditor’s reputation and the country’s development level

PurposeThe objective of this study is to determine the impact of GHG assurance on firms’ carbon emissions performance (CEP) regarding curbing carbon emissions and the effect on such by the GHG assurance provider’s affiliation and reputation. It also explores whether the affiliation and reputation of GHG assurance providers imply the relationship between GHG assurance and the firm’s CEP. Further, this study examines the moderating effect of the country’s development level on the relationship.Design/methodology/approachBased on a sample of international firms from 56 countries spanning the period from 2012 to 2020, this study utilizes the ordinary least squares (OLS) regression. We also run the OLS regression at times t+1 and t+2 to verify the baseline results. To address the endogeneity concerns arising from self-selection bias and the causality effect, this study applies the generalized method of moment (GMM) and the Heckman test.FindingsThis study finds that GHG assurance leads to better CEP by firms. We also find that engaging with accounting assurance providers leads firms to a better CEP than non-accounting assurance providers. Our results show that Big Four auditors can help firms decrease carbon emissions. We also find that the positive effect of GHG assurance is prevalent in firms operating in developed countries.Research limitations/implicationsOur study only considers the influence of the assuror’s reputation and affiliation on CEP without examining other factors that may influence the quality of assurance services provided.Practical implicationsOur study provides a practical implication related to the influence of a GHG assurance provider’s affiliation and reputation globally by providing evidence that accounting and Big Four assurance providers do play a significant role in a firm’s carbon emission performance. This study offers great insights into the GHG assurance impact on CEP with the interplay between the assuror’s affiliation and reputation and the country’s development.Originality/valueThis paper enriches the limit evidence on GHG assurance and CEP by providing novel evidence on the relationship between GHG assurance and a firm’s CEP. Moreover, this study provides insights into the implication of a country’s development level on the role of GHG assurance in CEP.

Bankruptcy spillovers and stock price crash risk of non-bankrupt firms

This paper examines whether corporate bankruptcies affect non-bankrupt firms' stock price crash risk. We observe that an upsurge in corporate bankruptcies adversely affects the crash risk of non-bankrupt firms in the industry. The increase in the crash risk following bankruptcy clustering in an industry is greater in financially constrained and financially distressed non-bankrupt firms. We also find that the creditor-in-control bankruptcy regime moderates the adverse effects of bankruptcy spillovers on the crash risk of non-bankrupt firms. Our results are robust to endogeneity tests (using GMM estimators) and tests that exclude industry downturns and macroeconomic shocks.

The Impact of Corporate Governance on Bank Risk-taking: Evidence of Islamic Banks in Gulf Cooperation Council (GCC) Countries

Purpose — This study investigates the impact of Islamic corporate governance variables on risk-taking within a sample of 31 Islamic banks (IBs) operating in six countries in the Arab Gulf region during the period 2013–2022. Design/Methodology/Approach — The study utilises content analysis and employs two econometric models: the random-effect generalised least squares (GLS) technique and the generalised method of moments (GMM) approach. Findings — The findings reveal that two characteristics of Sharīʿah supervisory boards (SSBs), namely cross membership and knowledge in accounting and finance, have a negative impact on bank risk. However, it is observed that SSB size demonstrates a positive correlation with bank risk-taking, indicating that SSBs face challenges in effectively performing their supervisory role. Furthermore, it is noted that during the pandemic period, banks demonstrated significantly higher levels of credit risk and global risk. Originality/Value — This research provides a valuable addition to the existing literature by conducting the inaugural analysis of the relationship between SSBs and bank risk-taking in the Arab Gulf region, adding to the understanding of Islamic corporate governance dynamics. Research Implications — The study suggests reinforcing the structure of SSBs in IBs in the Gulf Cooperation Council (GCC) countries by appointing members with educational backgrounds in business, accounting, and finance. Furthermore, it supports the idea that the presence of shared scholars in IBs facilitates rational decision-making by SSBs and contributes to reduced risk-taking. Haut du formulaire

Does official development assistance (ODA) cause the Dutch disease in developing countries

PurposeThis paper aims to investigate whether official development assistance (ODA) inflows to developing countries (lower-middle and low income) can cause the symptoms of Dutch disease or not.Design/methodology/approachThis study applies the methodology of dynamic panel data estimation with a one-step system generalized methods of moment (GMM) for the sample of 59 developing countries from 2001 to 2019.FindingsThe results indicate that ODA (as a percentage of gross domestic product (GDP)) rises by 1%, the real effective exchange rate (REER) appreciates by 0.252%. This finding reveals that these selected developing countries have faced the symptoms of Dutch disease. The countries with the higher ODA ratio have a higher effect of the Dutch disease, and the managed floating exchange rate regime is the lowest impacted, when compared to the fixed and flexible exchange rate.Practical implicationsThe selected countries are recommended to use ODA inflows right and efficiently. These ODA inflows should be invested in productive sectors or support for production rather than in consumption. The managed float exchange rate regime is applied to reduce the symptom of Dutch disease for the selected countries. The good cooperation of monetary and fiscal policies is important to absorb the huge ODA inflow and sterilize the adverse effects of the disease.Originality/valueThe paper contributes to the literature and empirical of the Dutch disease. An adverse effect of the huge ODA inflow to the developing countries appreciated of the real exchange rate and caused the symptom of the dutch disease.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-12-2022-0777

Islamic Banks’ Profit and Violations in Murābaḥah Financing

Purpose — This paper investigates the relationship between murābaḥah contracts and the profitability of Islamic banks, explicitly examining how potential Sharīʿah non-compliance issues related to murābaḥah contracts might impact the banks’ profitability. Design/Methodology/Approach — Employing the Generalised Method of Moments (GMM) estimation for fixed effects dynamic panels, this study analyses quarterly data from 2013Q4 to 2023Q1 of the four largest Islamic banks in Saudi Arabia. Findings — The results reveal a positive correlation between the increase in the value of murābaḥah contracts and Islamic earnings. While domestic macroeconomic conditions influence this relationship, international conditions have minimal impact. This investigation meticulously identifies instances of Sharīʿah violations within Islamic banks as they pursue a ‘search for yield’. Originality/Value — Prior studies have fallen short in establishing a definitive association between the profits of Islamic banks and the value of murābaḥah contracts. This research bridges this gap and introduces a novel dimension to the existing literature by illuminating the potential compromises in Sharīʿah compliance when employing murābaḥah contracts. The dual focus on both financial implications and ethical considerations makes this study unique, representing a significant contribution to the ongoing discourse in Islamic finance literature. Research Limitations/Implications — The availability of data on murābaḥah contracts may pose constraints to this study. Practical Implications — The analysis sheds light on various scenarios where Islamic banks may compromise their adherence to Sharīʿah principles in pursuit of higher profits, offering valuable solutions to address and rectify such violations.
