Abstract

Using the next-day and next-week returns of stocks in the Korean market, we examine the association of option volume ratios – i.e. the option-to-stock (O/S) ratio, which is the total volume of put options and call options scaled by total underlying equity volume, and the put-call (P/C) ratio, which is the put volume scaled by total put and call volume – with future returns. We find that O/S ratios are positively related to future returns, but P/C ratios have no significant association with returns. We calculate individual, institutional, and foreign investors’ option ratios to determine which ratios are significantly related to future returns and find that, for all investors, higher O/S ratios predict higher future returns. The predictability of P/C depends on the investors: institutional and individual investors’ P/C ratios are not related to returns, but foreign P/C predicts negative next-day returns. For net-buying O/S ratios, institutional net-buying put-to-stock ratios consistently predict negative future returns. Institutions’ buying and selling put ratios also predict returns. In short, institutional put-to-share ratios predict future returns when we use various option ratios, but individual option ratios do not.

Abstract

Purpose

Outstanding unexercised stock options can motivate managers to engage in actions that increase the value of their company’s stock, including buying back their firm’s stock. The objective of granting stock options to managers is to align their interests with stockholders by tying a portion of their compensation to the company’s stock performance. However, unexercised stock options may have unintended consequences by providing managers with a vested interest in artificially boosting stock prices via stock buybacks. The primary objective of this research is to study the main factors that influence firms' buyback decisions amongst hospitality firms at a time when these firms were clamoring for taxpayer bailouts. Results from logistic regression seem to suggest that outstanding executive stock options are a major contributory factor in a firm’s buyback decision. Estimates also indicate that larger, more profitable firms will likely engage in stock buybacks. These findings survive a battery of tests.

Design/methodology/approach

The authors use logistic regression to predict the probability of a firm’s buyback decision based on a given set of exogenous explanatory variables.

Findings

The paper supports the hypothesis that buyback decisions are guided by the motive to prop support stock prices in the presence of outstanding restricted stock options/warrants granted to firms' executives.

Research limitations/implications

The paper focuses on the buyback decision of U.S. hospitality firms. The results, therefore, might not be generalizable to firms in other industries or countries.

Practical implications

U.S. share repurchase corporate policy and government regulation needs to be revisited given the economic imperative for firms to invest in activities to restore employment and put them in a position for economic recovery.

Social implications

Public criticism of the size, structure and form (i.e. loan vs grant) of COVID-19 bailouts warrants an examination of whether the factors that drive hospitality and tourism firms to repurchase shares support economic recovery.

Originality/value

Consistent with agency theory, the authors find a significant positive association between outstanding restricted stocks and a firm’s decision to support the stock prices by buying back shares.

Abstract

Purpose

This study delves into the nuanced implications of short-sale constraints on stock prices within the context of stock market efficiency. While existing research has explored this relationship, inconsistencies persist in their findings. The purpose of this study is to conduct a comprehensive review of literature to elucidate the reasons behind these disparities.

Design/methodology/approach

A systematic review of existing theoretical and empirical studies was conducted following the PRISMA method. The analysis centered on discerning the factors contributing to the divergence in projected stock prices due to these constraints. Key areas explored included assumptions related to expectations homogeneity, revisions, information uncertainty, trading motivations and fluctuations in supply and demand of risky assets.

Findings

The review uncovered multifaceted reasons for the disparities in findings regarding the influence of short-sale constraints on stock prices. Variations in assumptions related to market expectations, coupled with fluctuations in perceived information uncertainty and trading motivations, were identified as pivotal factors contributing to differing projections. Empirical evidence disparities stemmed from the use of proxies for short-sale constraints, varied sample periods, market structure nuances, regulatory changes and the presence of option trading.

Originality/value

This study emphasizes the significance of not oversimplifying the impact of short-sale constraints on stock prices. It highlights the need to understand these effects within the broader context of market structure and methodological considerations. By delineating the intricate interplay of factors affecting stock prices under short-sale constraints, this review provides a nuanced perspective, contributing to a more comprehensive understanding in the field.

Abstract

Purpose

Remuneration policies may differ from country to country, and their effect on bank stability could be due to the legal framework. Therefore, this study aims to investigate how the legal system impacts the relationship between CEO compensation and bank stability across countries.

Design/methodology/approach

To test the study hypotheses, the authors use panel data of 74 banks operating in ten OECD countries during the period 2009–2016 and apply the generalized moments method regression model to better remediate the endogeneity problem.

Findings

The findings confirm that a country’s banking regulations significantly affect its bank stability. Common law countries have less bank stability than civil law countries. This result can be interpreted by the fact that, in common-law countries, banks’ CEO are strongly protected by the law, so they allocate a large part of bank assets to risky loans to improve their variable remuneration.

Practical implications

The research can help policymakers understand bank stability in one country. Any legal reform would require prior knowledge of how risk-taking may arise in executive compensation.

Originality/value

The contribution is to explain the controversial effect of executive compensation on bank stability in the framework of legal theory. The authors argue that regulators should monitor compensation structures and that the country’s legal origin of law shapes the CEO compensation structure and is a determinant of bank stability. To the best of the authors’ knowledge, there are no studies exploring this field. So, this study tries to shed more light on the dark side of CEOs’ behavior when undertaking risky projects to maximize their remuneration.

Abstract

Purpose

The purpose of this study is to analyse and compile the literature on various option pricing models (OPM) or methodologies. The report highlights the gaps in the existing literature review and builds recommendations for potential scholars interested in the subject area.

Design/methodology/approach

In this study, the researchers used a systematic literature review procedure to collect data from Scopus. Bibliometric and structured network analyses were used to examine the bibliometric properties of 864 research documents.

Findings

As per the findings of the study, publication in the field has been increasing at a rate of 6% on average. This study also includes a list of the most influential and productive researchers, frequently used keywords and primary publications in this subject area. In particular, Thematic map and Sankey’s diagram for conceptual structure and for intellectual structure co-citation analysis and bibliographic coupling were used.

Research limitations/implications

Based on the conclusion presented in this paper, there are several potential implications for research, practice and society.

Practical implications

This study provides useful insights for future research in the area of OPM in financial derivatives. Researchers can focus on impactful authors, significant work and productive countries and identify potential collaborators. The study also highlights the commonly used OPMs and emerging themes like machine learning and deep neural network models, which can inform practitioners about new developments in the field and guide the development of new models to address existing limitations.

Social implications

The accurate pricing of financial derivatives has significant implications for society, as it can impact the stability of financial markets and the wider economy. The findings of this study, which identify the most commonly used OPMs and emerging themes, can help improve the accuracy of pricing and risk management in the financial derivatives sector, which can ultimately benefit society as a whole.

Originality/value

It is possibly the initial effort to consolidate the literature on calibration on option price by evaluating and analysing alternative OPM applied by researchers to guide future research in the right direction.

Abstract

Purpose

The present study investigates the impact of accounting comparability on chief executive officer (CEO) incentive plans and the moderating role of board independence for companies listed in Tehran Stock Exchange (TSE).

Design/methodology/approach

The information about 177 companies in 2014–2021 was examined. In this study, equity-based compensation and cash-based compensation were used as the CEO incentive plans. The equity-based compensation was calculated through the ownership of the CEO shares.

Findings

The results suggest that the higher accounting comparability increases not only CEO equity-based compensation, but also cash-based compensation. Board independence also strengthens the relationship between accounting comparability and CEO compensation. Hypothesis testing based on robustness checks confirmed these results.

Originality/value

The paper is pioneering, to the authors' knowledge, in identifying how board independence moderates the impact of accounting comparability on CEO compensation. The findings provide insights into economic consequences to the firm related to accounting comparability and board monitoring. The results have important practical implications for international investors to evaluate accounting comparability, corporate governance mechanisms and CEO incentives.

Abstract

Theoretical Basis

The theoretical basis for the case is information asymmetry and signaling theory, with buybacks providing a mechanism for reducing information asymmetry between management and investors. The controversy surrounding buybacks has led to political and regulatory scrutiny, which, consistent with evidence from academic research, may affect corporate behavior.

Research methodology

The compact case is based on secondary, public information about stock buybacks. All sources used are cited in-text, with full citations included in the references section at the end of the teaching note.

Case Overview/Synopsis

Stock buybacks, a means of providing returns to shareholders, have recently received increased scrutiny by politicians, media and shareholder activists. Proponents have argued that buybacks result in efficient allocation of capital by returning funds to shareholders, whereas opponents have criticized buybacks for enriching executives, providing tax advantages to shareholders and contributing to income inequality. Corporations did not curtail their use of buybacks after the Inflation Reduction Act of 2022 imposed an excise tax. The case frames the buyback debate in current events and focuses on the buyback activity of Apple. The case provides students the opportunity to analyze alternative ways that companies can provide returns to shareholders, evaluate impacts of buybacks on corporate stakeholders and appraise the reasons for, and implications of, current controversy regarding buybacks.

Complexity/Academic Level

This compact case is appropriate for upper-level undergraduate or graduate courses in financial accounting, tax and finance. This case provides an opportunity to analyze and evaluate stock buyback decisions in the context of the current controversy related to buybacks.

This paper aims to empirically examine the impact of mandatory CSR disclosure on the CEO pay performance sensitivity.

Abstract

Purpose

This paper aims to empirically examine the impact of mandatory CSR disclosure on the CEO pay performance sensitivity.

Design/methodology/approach

Using the mandatory requirement of CSR disclosure as an exogenous shock, the authors compare the changes in CEO pay performance sensitivity for treatment firms with control firms through a difference-in-difference (DiD) approach.

Findings

The authors find that mandatory CSR disclosure enhances CEO pay performance sensitivity. The results also show that monitoring CEO power is a conduit through which mandatory CSR disclosure affects CEO pay performance sensitivity. The positive impact is more profound in firms with a powerful CEO, i.e. one who is politically well-connected, holds dual roles as both CEO and Chairman, and/or has had a long tenure. Furthermore, the increased CEO pay performance sensitivity after the mandate is prominent among state-owned enterprises (SOEs) only.

Practical implications

The findings of this paper have implications for other economies with similar institutional backgrounds as China. Although the mandatory CSR disclosure does not require firms to spend on CSR investment, the mandatory CSR disclosure alters firm behaviour, and mitigates agency problems.

Originality/value

This paper contributes to the studies on the impact of CSR disclosure on firms' behaviour. To the authors' knowledge, this is the first study to examine the effects of mandatory CSR disclosure on CEO pay performance sensitivity using the quasi-natural experiment settings.

This paper aims to review empirical research on the relationship between institutional ownership (IO) and board governance (85 studies).

Abstract

Purpose

This paper aims to review empirical research on the relationship between institutional ownership (IO) and board governance (85 studies).

Design/methodology/approach

Based on agency and upper echelons theory, the heterogeneous monitoring function of specific types and the nature of institutional investors on board composition, compensation and chief executive officer (CEO) characteristics will be focused.

Findings

The author found that most studies have referred to archival studies, analyzed the impact of board governance on IO, focused on CEO characteristics, neglected IO heterogeneity and advanced regression models to address endogeneity concerns. In line with the theoretical framework, the relationship between total IO and board governance is heterogeneous. However, specific types such as foreign, dedicated and pressure-resistant institutions represent active monitoring tools and push for increased board governance.

Research limitations/implications

The author provided useful recommendations for future research from a content and methodological perspective, e.g. the need for analyzing the impact of IO on sustainable board governance and other characteristics of top management team members, e.g. the chief financial officer.

Practical implications

As many regulatory bodies implemented regulations to promote shareholder rights and board governance, this literature review highlights the connections of both corporate governance mechanisms. Managers should conduct a careful and timely investor analysis and change the composition and compensation of the board of directors in line with institutional investors’ preferences.

Originality/value

This analysis makes useful contributions to prior research by focusing on IO and board governance, whereas the author structured the heterogeneous variables and results within the structured literature review. The authors guides researchers, regulatory bodies and business practice in this corporate governance topic.

Abstract

Purpose

Green technology innovation is the organic combination of green development and innovation driven. It is also a powerful guarantee for shaping sustainable competitive advantages of manufacturing enterprises. To explore what kind of executive incentive contracts can truly stimulate green technology innovation, this study aims to distinguish the equity incentive and reputation incentive, upon their contractual elements characteristics and green governance effects, and then put forward suggestions for green technology innovation accordingly.

Design/methodology/approach

This study establishes an evaluation model and uses empirical methods to test. Concretely, using data from A-share listed manufacturing companies for the period from 2007 to 2020, this study compares and analyzes the impact of equity and reputation incentive on green technology innovation and explores the relationship between internal green business behavior and external green in depth.

Findings

This study finds that reputation incentives focus on long-term and non-utilitarian orientation, which can promote green technology innovation in enterprises. While equity incentives, linked to performance indicators, have a inhibitory effect on green technology innovation. Internal and external institutional factors such as energy conservation measures, the “three wastes” management system, and environmental recognition play the regulatory role in the relationship between incentive contracts and green technology innovation.

Originality/value

Those findings validate and expand the efficient contracting hypothesis and the rent extraction hypothesis from the perspective of green technology innovation and provide useful implications for the design of green governance systems in manufacturing enterprises.
