This study investigates the impact of conservative financial reporting on corporate diversification, in order to explore whether accounting policy plays a role in mitigating agency problems associated with corporate decisions. Based on a sample of U.S. publicly listed firms in the period 2000–2017, this study initially reveals that diversification has an adverse effect on firm value. Our findings indicate that the increase in accounting conservatism leads to a subsequent reduction in the degree of corporate diversification. Additionally, the increase in accounting conservatism helps enhance the excess value attributed to diversification, suggesting that conservatism can alleviate the detrimental influence of diversification on firm value. Our results further indicate that the effect of accounting conservatism is more pronounced for firms with higher information asymmetry or poor corporate governance structure. Overall, the findings suggest that conservative accounting plays an effective monitoring role in disciplining management’s corporate strategies of diversification, and therefore, benefits shareholders and capital markets.

Theoretical models predict that the threat of outside blockholder exit can mitigate agency problems and force managers to undertake actions that would maximize firm value in the long run. We examine whether the institutional blockholder exit threat curbs managerial misbehavior and short-termism reflected in real earnings management. Our study exploits a natural experiment—the Polish pension fund reform of 2013 that encouraged pension funds to trade more actively and imposed a real threat of exit on their portfolio companies. Using a difference-in-differences approach, we provide evidence that the reform significantly decreased the level of real earnings management in “treated” companies, that is, companies with open-ended pension funds (OFEs) playing the role of blockholders. The effect was more significant for firms in a multiple blockholder setting, firms under common ownership, and firms with higher insider’s stakes. Moreover, we confirmed that treated companies that decreased real earnings management in the post-reform period experienced the increased long-term operating performance.

This research examines how option trading activity reduces information asymmetry through the CEO’s and ordinary employee’s awareness of firm value and their pay related to firm performance. Our findings demonstrate that companies with more options trading activity have a higher CEO-employee pay ratio, which is consistent with the tournament theory. Option trading illustrates that both CEOs and employees understand their relevant payment based on the precise firm value. This advantage of option trading becomes weak for firms with higher profitability, for employees with more bargaining power, and for CEOs with a higher risk incentive.

This experimental research investigates the effect of different types of environmental information on investor judgment. By examining three experimental cases varying the level of environmental disclosure, we evaluate the investment judgments of professional (Study 1) and private German investors (Study 2). Primarily, we investigate whether traditional, commonly disclosed environmental information affects investor judgments. Furthermore, we explore the effects of linking non-financial reporting elements to quantitative financial measures through the EU taxonomy by adding taxonomy indicators. Specifically, we operationalized the case where companies fall into a category of poor environmental performance by taxonomy classification. We find that only traditional environmental disclosure in combination with standardized taxonomy-aligned information (below average), influences the investment judgment. However, professional investors exhibit a significantly negative response, while private investors show a significantly positive reaction when constraining reporting flexibility through the inclusion of standardized taxonomy measures with poor performance. Consequently, we conclude that the connection between non-financial reporting elements and quantitative standardized financial measures enhances transparency for professional investors. Private investors, on the other hand, reward additional taxonomy-aligned environmental information irrespective of its content. This implies that environmental information generally conveys positive signals to private investors, but uncertainty in investment judgment can be assumed.

In this study, we examine the effects of the degree of CEO optimism on their risk-taking behaviors and on firm value and show that CEOs with low overconfidence tend to take on more risk (in terms of tail risk) and have a lower Tobin’s Q than companies whose CEOs have moderate or high overconfidence. To do so, we use a sample of life insurance companies divided into three subsamples, based on the degree of CEO overconfidence (OC): low OC, moderate OC, and high OC. Our additional analyses indicate that, before the 2008 global financial crisis, all three OC subsamples have a positive effect on Tobin’s Q from the net credit default swap (CDS) sell positions. But, after the financial crisis, all the three OC groups use CDS to reduce firms’ risk-taking behavior, rather than to increase firm value.

Manipulating real activities is generally regarded as more damaging to a firm’s long-term growth and value than accrual-based manipulations. We consider this point of view and build on the agency theory framework for investigating the role of independent directors’ (INDs’) tenure and connection to several boards in controlling real-earnings management (REM) practices. We analyze a sample of UK listed non-financial companies over the period between 2005 and 2018. The potential endogeneity issue was controlled by the application of the two-step system-GMM estimations. The research findings suggest that REM was lower in those firms whose INDs were connected to several boards at a time. The findings also show that the association between INDs’ tenure and REM varied with the phases of their tenure. Directors in the early stage of their tenure are less effective at controlling REM, however, as their tenure grew, they generate better oversight over the management conduct, thereby reducing REM. Contrary to this, extended tenure is shown as positively associated with higher REM practices. The overall findings thus suggest that the board monitoring role protects the stakes of the shareholders by constraining REM when INDs have better expertise and rich information acquired through their presence on multiple boards—and when they have moderate board tenure, which is neither too short nor too long. We argue that due to the importance of the role of INDs in the current global scenario this study has policy implications.

I investigate the impact of securitization on the risk-taking by bank holding companies (BHCs). For 2001 to 2017, I find a negative relationship between securitization and the risk appetite of BHCs. I find a negative relationship between securitization and the risk appetite of BHCs that is consistent with the recourse hypothesis of securitization. I also discover that the equilibrium in this relationship changes from the pre-crisis to the crisis period (crisis effect). This crisis effect hampers BHCs’ ability to engage in securitization that leads them to accumulate more risky assets on their books due to the deteriorated quality of their loan portfolios. This equilibrium then reverses after the crisis (post-crisis effect) due to policy makers’ response to the excessive risk-taking that manifested during the crisis. Moreover, I find that the securitization of residential mortgages not only boosts the recourse hypothesis but also triggers the crisis effect. My findings provide novel empirical insights into the different nexuses between the securitization and risk appetite of BHCs around the financial crisis.

This work examines the direct impact of solar events on the financial sector of the United States, while also investigating their indirect effects on other sectors of the US economy. The study introduces a cutting-edge methodology based on the Global Vector Autoregressive (GVAR) model, utilizing a comprehensive dataset, to estimate indirect global impulse response functions. By putting forward this approach, the study highlights the significant contribution of solar events on financial and insurance activities, establishing a clear connection to the broader US economy. Moreover, it quantifies and demonstrates the direct and indirect influence of solar events on the US economy, paving the way for future in-depth investigations in this field.

We investigate the performances of the ARFIMA, HAR, and EGARCH models in capturing the time-varying property of idiosyncratic volatility (IVOL). We find that the expected IVOL predictions by HAR are superior. In diverse portfolio scenarios, a greater degree of judgment is required to assess the pricing ability of expected IVOLs. For the lowest value-weighted quintiles and the expected IVOL estimated by the HAR model, the IVOL-return relationship is negative. Conversely, the IVOL-return relationship is positive for the expected IVOL estimated by the EGARCH model. Further evidence suggests a complicated and mixed relationship between the expected IVOL estimated by the ARFIMA model and stock returns.

This study conducts a detailed investigation into the interplay between major sporting events, specifically the ICC Cricket World Cups and FIFA Football World Cups, and their potential impact on the relationship between dividend announcements and stock market returns. Beyond the customary exploration of investor sentiment and its connection to stock market returns, our research thoroughly examines the effects of these significant sports events on the stock market's reaction to dividend announcements. Drawing on extensive FTSE 350 index data spanning January 1990 to December 2021, we employ event study methodology as the primary analytical framework. To bolster the reliability of our findings, we apply the Generalized Method of Moments (GMM) estimation method, addressing potential endogeneity concerns. Our results uncover a distinct pattern—the stock market exhibits a less favourable response to dividend increases announced following England's victories in major sporting events, such as the FIFA Football World Cup and ICC Cricket World Cup, compared to instances where they faced defeat. Additionally, we observe a more negative market response to dividend decreases announced following England's losses in these pivotal sporting events, as opposed to England emerging victorious in these key contests. This research contributes valuable insights into the intricate relationship between sports passion and market dynamics, offering implications for both scholarly discourse and investment strategy formulation.
