This study investigates whether real earnings management (RealEM) affects firms’ debt choice. We find that firms with higher RealEM rely more on bank debt than public debt as a source of financing. Our cross-sectional analysis reveals that the RealEM–debt choice association is more significant in the presence of poor corporate governance and heightened financing constraints. We also observe that the connection between RealEM and bank debt is more significant for suspect firms (i.e., firms with a genuine motive for opportunistic earnings management) than their non-suspect counterparts. Additionally, we find that RealEM increases the use of trade credit and short-term debt. Our findings are robust to endogeneity concerns and other issues. Overall, our findings suggest that the impact of information asymmetry issues arising from RealEM is less for bank than for public debtholders.

Banks play a crucial role in sustainable development, an area increasingly governed by self-regulation. This study examines whether banks that commit to self-regulation by adopting the Principles for Responsible Banking (PRB) exhibit enhanced Environment, Social, and Governance (ESG) performance. Utilizing Bloomberg ratings, we find that PRB adopters consistently show higher ESG scores than non-adopters, both before and after adoption. This suggests that a commitment to self-regulation serves as a reliable signal of responsible banking practices. Notably, the superior performance of PRB adopters relative to non-adopters is primarily driven by a strong pre-adoption commitment to transparency on ESG issues. We discuss possible explanations for this trend, including the role of early adopters in advancing industry-wide standards. Additionally, our findings reveal a negative association between regulatory quality and ESG scores, implying that banks may leverage ESG disclosures to mitigate information asymmetries in weaker institutional environments.

This study demonstrates that using derivatives can significantly improve stock liquidity. We conduct several tests to check for robustness of our findings and control for potential endogeneity in our results. We observe that the decrease in stock illiquidity due to derivative usage is more pronounced for firms with high information asymmetry, high firm-specific risk, and negative investor sentiment. Ownership stakes held by foreign institutional investors and domestic promoters do not influence how derivative usage affects stock liquidity. This relationship is significant in the presence of large and independent boards. Our results emphasize the liquidity creation role of derivative usage, which complements other functions of derivatives markets, such as price discovery and risk management. Our findings are relevant for companies operating in foreign capital markets and for international investors who include Indian stocks into their portfolios.

This study proposes a novel framework that decomposes volatility and higher-moment kurtosis into good and bad volatility/kurtosis—related to positive and negative shocks, respectively. Accordingly, we analyze the spillover effects of good and bad volatility/kurtosis between sustainable and traditional investments separately. During most periods, bad volatility spillovers dominate good volatility spillovers, whereas good kurtosis spillovers dominate bad kurtosis spillovers. However, during specific extreme events, such as Brexit and COVID-19, bad kurtosis spillovers dominate. This study’s findings can help investors in developing extreme risk management strategies and policymakers in preventing harmful shock transmissions across markets and fostering financial stability.

The importance of exchange rate volatility forecasting has both practical and academic merit. Our aim is to provide a comprehensive analysis of the forecasting ability of financial and macroeconomics variables for future exchange rate volatility. We employ seven widely traded currencies against the US dollar and examine linear models and a variety of machine learning, dimensionality reduction and forecast combination approaches, along with creating a grand forecast (amalgamation approach) from these approaches. Our findings highlight the predictive power of the amalgamation approach, as well as the positive contribution of macroeconomic and financial variables in the forecasting experiment. Furthermore, we generate forecasts on the separate frequencies of volatility using wavelet analysis, in order to extract frequency-related information and examine timing effects in the performance of the methods.

This study examines the relationship between firms’ biodiversity risk, climate susceptibility, and bankruptcy risk. The findings indicate that firm exposure to biodiversity risk increases the likelihood of financial distress. Furthermore, we document that firms’ susceptibility to climate risk increases the likelihood of bankruptcy risk. We also demonstrate that financial constraints, growth opportunities, and membership in carbon-intensive industries can worsen or alleviate the bankruptcy implications of climate-related risk. Firms’ continent of operation is also an important consideration. The findings imply that severe climate-related vulnerabilities and firm biodiversity risk have profound consequences for corporate outcomes. This study sheds more light on how corporate financial outlook is impacted by ecological degradation and climate-related vulnerabilities.

This study investigates the relationship between organization capital, dividends, and firm value across 61 countries. We find that firms with higher organization capital distribute more dividends. By exploiting changes in the stringency of national labor regulations, we demonstrate that this effect strengthens when labor markets become more flexible. Additionally, we document that the market places a premium on dividend payouts from firms with higher organization capital. Further analysis reveals that this premium differential and the positive organization capital-dividend payouts relationship, are more pronounced in firms and countries marked by substantial agency issues. The robustness of our evidence is affirmed through several endogeneity tests, supporting the agency view of organization capital.

This study examines the link between CEO age and firm environmental performance. Building on the upper echelons theory, we predict that a firm is more environmentally friendly if CEOs are younger. Using hand-collected data of a total 12,512 plant-year observations for 1,074 individual firms in the period from 2010 to 2022, we document evidence that younger CEOs release significantly less greenhouse gas emissions, consistent with our conjecture. Additionally, we note that younger CEOs outperform older CEOs in terms of greenhouse gas emissions by investing more in abatement initiatives, increasing manufacturing efficiency, and increasing their use of ecologically friendly fuel. Our evidence of CEO age offers relevant implications for directors, shareholders, and financial regulators.

Employing a panel dataset encompassing 4,412 banks from 87 countries from 1990 to 2020, we apply the autoregressive distributed lag (ARDL) model to investigate the relationship between financial openness, banks’ liability composition, and bank risk. Our findings reveal that financial openness can directly lead to an increase in bank risk in the short term but a reduction in bank risk over the long term. Additionally, we identify the composition of bank liabilities as a novel channel between financial openness and bank risk. Specifically, in the short term, financial openness amplifies bank risk through an escalation in the ratio of short-term liabilities juxtaposed with a decrease in the ratio of long-term liabilities. Conversely, in the long term, financial openness diminishes bank risk by diminishing short-term liabilities’ ratios while concurrently enhancing the proportions of long-term liabilities. Furthermore, it is noted that the direct effects of financial openness on banking risk, whether short- or long-term, may exhibit heterogeneity across different periods, country development levels, and types of capital flow.

We explore the ability of the distance between short- and long-run moving averages, called MAD, to predict future returns of international market-wide indices. MAD portfolios yield abnormal profits after transaction costs, which do not reverse in the long run. This suggests that anchoring to long-run moving averages is a global phenomenon that applies also to market-wide indices. The annualized MAD portfolios’ alpha values are double-digit, with Sharpe ratios significantly higher than the global benchmarks. Similar results for developed economies and developed markets indicate that international diversification is still effective and offers significant economic benefits even among developed countries.
