Information Privacy and Security Associated with Healthcare Technology Use

This dissertation consists of three studies that investigate the information privacy & security associated with healthcare technology use. Essay 1 PRISMA-style systematically reviews the existing literature on privacy information disclosure in IoT technology and serves as the theoretical foundation of the current research. It is crucial to comprehend why, how, and under what consequences individuals choose to disclose their personal and health information since doing so is beneficial to the company. This SLR method allows us to find those factors that significantly impact individuals' behavioral intention to disclose personal information while using IoT technologies. Essay 2 posits, develops, and tests a comprehensive theoretical framework built upon the theory of planned behavior and the health belief model to examine factors affecting willingness to disclose PHI in order to use WFDs. A research survey is designed and distributed to a crowdsourcing platform, Mechanical Turk (M-Turk). Research hypotheses are tested using partial least square – structural equation modeling (PLS-SEM). To achieve this purpose, Essay 3 extends the findings from the previous essay and further investigates the caregiver context. Therefore, we developed a novel theoretical model utilizing privacy calculus theory and the technology acceptance model to investigate the willingness of the elderly to disclose …

Incorporating Ethics in Delegation To and From Artificial Intelligence-Enabled Information Systems

AI-enabled information systems (AI-enabled IS) offer enhanced utility and efficiency due to their knowledge-based endowments, enabling human agents to assign and receive tasks from AI-enabled IS. As a result, this leads to improved decision-making, ability to manage laborious jobs, and a decrease in human errors. Despite the performance-based endowments and efficiencies, there are significant ethical concerns regarding the use of and delegation to AI-enabled IS, which have been extensively addressed in the literature on the dark side of artificial intelligence (AI). Notable concerns include bias and discrimination, fairness, transparency, privacy, accountability, and autonomy. However, the Information Systems (IS) literature does not have a delegation framework that incorporates ethics in the delegation mechanism. This work seeks to integrate a mixed deontological-teleological ethical system into the delegation mechanism to (and from) AI-enabled IS. To that end, I present a testable model to ethically appraise various AI-enabled IS as well as ethically evaluate delegation to (and from) AI-enabled IS in various settings and situations.

Organizational Blockchain Assimilation towards Supply Chain Pain Management and Collaboration

Extant research on technology adoption provides limited insights into the extent of technology penetration into an organization's work routines, especially in collaborative efforts across supply chains. Further research is required to delve into the broader scope of permanent technology-based solutions that effectively tackle specific issues within the supply chain. This dissertation examines blockchain through three essays to fill these research gaps and contributes to blockchain-based supply chain collaboration and performance literature. Essay 1 examines supply chain behavioral drivers of blockchain assimilation by grounding the hypotheses on social network theory. Findings indicate that supply chain learning, collaboration, and network prominence will affect blockchain assimilation through a cross-sectional survey of supply chain professionals familiar with blockchain. It provides psychometrically validated scales for blockchain assimilation and network prominence, adding to the blockchain literature. Essay 2 builds on institutional theory to argue that peripheral organizations in the blockchain-based network will succumb to institutional pressures and that blockchain principles will require them to play crucial roles in supply chain collaboration efforts to gain legitimacy. By adopting a multi-method approach of a vignette-based experiment and a survey, the findings help supply chain collaboration practitioners manage institutional pressures across emerging blockchain-based systems, particularly for organizations in the …

Linguistic Racism in the Marketplace

Linguistic racism is faced by non-native customers due to their different language style when they go through the service exchange process. Despite its prevalence and importance, there is a dearth of research about linguistic racism in the marketing literature, especially from consumers' perspectives. This dissertation thus aims to address this gap by focusing on consumers' cognitive and affective responses as a result to their linguistic racism experiences when they interact with service employees (native speakers) from the host country. Toward this goal, first (Essay 1), a qualitative study is performed to anchor the dissertation in the customers' real-life experiences and to help identify key associated themes which are further empirically examined (Essay 2 & 3) in this three-essay format dissertation. Essay 2 empirically investigates if the identity assignment through ones' language style makes customers feel stigmatized and influence their psychological well-being. In addition, how these experiences subsequently influence their inclination to use technology-mediated interfaces. Similarly, the main objective of Essay 3 was to employ a sociological perspective to examine the impact of language-based chronic social exclusion on non-native customers' psychological and behavioral responses in the marketplace. Moreover, their intention to pay higher tip as a refocusing strategy when these customers …

The Effects of Generational Stereotypes and Attribute Affirmation on the Collection of Audit Evidence (open access)

The Effects of Generational Stereotypes and Attribute Affirmation on the Collection of Audit Evidence

As the workplace has evolved over the past few years, several studies have documented perceived differences in personalities, values, and preferences between generations in the workplace, including in public accounting. In this study, I examine whether exposure to a negative preconceived belief about a staff auditor's generation (generational stereotype) influences the affective state of staff auditors and ultimately causes them to reduce the extent to which they communicate with a client manager to gather the necessary information to perform an audit adequately. I also investigate whether attribute affirmation from a work buddy helps elicit positive affect to mitigate the effects that exposure to negative generational stereotypes may have on audit evidence collection. I conducted a 2 x 2 experiment using graduate auditing students as a proxy for staff auditors. I find that general affect (i.e., mood) rather than interpersonal affect (i.e., likability), drives the negative effect of exposure to generational stereotypes on willingness to collect more audit evidence. I also find that high levels of negative mood can negatively impact participants' self-efficacy. I, however, failed to find evidence of a moderated mediation. The presence of an attribute affirmation results in an insignificant increase in positive affect. When staff auditors are …

Corporate Environmental Litigations: Peer Effects and Its Relationship to Firm Environmental, Social and Governance (ESG) Performance

The dissertation analyzes three issues related to corporate environmental performance. In the first essay, I analyze the stock price reactions of the defendant firms and their peer firms to environmental lawsuits. Empirical evidence finds that the defendant and their peer firms experience negative and significant cumulative abnormal returns to the announcement of environmental lawsuits. Additionally, cross-sectional analyses find certain firm characteristics, such as profitability, growth opportunities and leverage can influence the market reaction. Furthermore, if the plaintiffs are government agencies or corporations instead of individual citizens, the defendant and peer firms experience higher negative market reactions. The second essay examines if a firm's environmental, social, and governance (ESG) performance can moderate the negative market response to environmental lawsuits. The results are mixed. The overall sample of the defendant and their peer firms show that ESG performance is not a significant factor in mitigating the negative market response. However, an interesting finding shows, for defendant and peer firms in the environmentally sensitive industries, better ESG ratings help reduce the adverse market reactions. The final essay investigates whether the defendant and peer firms improve their ESG performance in the next two years following the lawsuits. The results indicates that firms generally experience …

Worker Displacement by Artificial Intelligence (AI): The Impact of Boundary-Spanning Employees

Limited literature examines the impact of the displacement of boundary-spanning employees artificial intelligence (AI). Scholars and practitioners appear focused on tangible benefits of AI adoption, and do not seem concerned by any less tangible and possibly untoward implications of worker (particularly boundary-spanning worker) displacement. My dissertation addresses this gap in the literature. In Essay 1, a qualitative study is performed to anchor the research on the appropriate ethnographic setting, the firms where this displacement phenomenon is taking place, by utilizing the Straussian grounded theory approach. The outcome of iterative coding of the first order data collected from the interviews and content analysis is a conceptual framework which amongst other findings shows how the unique competences of boundary-spanning employees and those of AI are best suited for different spectra of interorganizational collaborative activities. In Essays 2 and 3, I investigate major themes that emerged from Essay 1 utilizing quantitative and qualitative research methods in both studies. Initially I test research models using structural equation modelling on practitioner survey data, after which I probe further via focused interviews to better understand the survey results. The two papers allow us to put forth several theoretical and managerial contributions, specifically emphasizing the positive essential …

Who are You Going to Believe: Me or Your Lying Eyes? Three Essays on Gaslighting in Organizations

In this dissertation, I theorize on how gaslighting manifests in managerial and organizational settings. I discuss the process of gaslighting and how the use of various manipulation tactics manifests between people in organizations over time. I take three distinctive approaches to study this complex phenomenon. First, using a rich case study, I develop new theory to explain how one notorious child molester was able to sustain a career for decades while assaulting hundreds of children and young women. In doing so, I introduce the concept of gaslighting which previously has only been rigorously applied to intimate interpersonal relationships in domestic (e.g., at home) settings. In essay 2, I expand on the individual level theory developed in essay 1 to develop a more generalized theory of gaslighting in organizations. I situate gaslighting within a nomological net of related constructs and illustrate how gaslighting is a unique construct with different antecedents and consequences that occurs in organizations more often than it should. In my final essay, I build on one of the propositions developed in essay 2 and empirically test what antecedents are likely to influence whether or not a firm is accused of gaslighting on Twitter. Through doing so, I find …

Three Essays on Collective Privacy and Information Security

In Essay 1, we seek to expand the insights on an individual's decision to share group content. Social networking sites (SNS) have become a ubiquitous means of socializing in the digital age. Using a survey, we collected data from 520 respondents with corporate work experience to test our research model. Our analysis highlights the complex interplay between individual and group factors that shape users' risk-benefit analysis of sharing group content on social networking sites. Furthermore, the results of this study have important implications for social networking site design and policy, particularly with regard to providing granular control over the privacy settings of group content and clear and concise information about the potential risks and benefits of sharing group content. Essay 2 aims to extend the knowledge of information security policy (ISP) compliance. Using a comprehensive approach, we extended the perspective of control mechanisms in the context of ISPs. It is evident that maintaining information security is an important concern for organizations of all sizes and industries. Organizations can establish policies and procedures to regulate and ensure compliance with information security policies, and various control mechanisms can be employed to ensure compliance. Among these control mechanisms, enforcement, punishment, evaluation, and recognition …

Freight Forwarder Satisfaction: A Conceptualization and an Empirical Test of Effect on Airport Customer Loyalty and Competitiveness

In 2018, global gross domestic product (GDP) was US$86.3 trillion, and almost a quarter of that value was due to international trade with a value of US$19.6 trillion. Air cargo accounts for about 35 percent of that trade value (approximately US$6.86 trillion). Moreover, from the perspective of the airport sector, air cargo revenue contributes between 20 to 70 percent of airport revenue. The global airport revenue for freight in 2018 was US$250 billion. Despite the interest and research activities surrounding competition and competitiveness of airports and specifically among airlines and passengers, it appears scholars have overlooked research concerning the competitiveness of airports when it comes to air cargo. This study attempts to fill the gap in the supply chain and logistics literature by putting forward a framework and ultimately operationalizing the framework highlighting the pivotal role of air cargo in the supply chain domain and within the global economy. Specifically, the framework is operationalized within the freight forwarding air cargo supply chain domain – providing insight into this important yet understudied phenomenon. The population of interest is freight forwarders from the Dubai International Airport, United Arab Emirates. The Middle East represents 18 percent of the world's air cargo volume and …

A Heuristic Approach to Selection of Analytical Methods: Three Empirical Healthcare Studies

Managers rely on analytics to make decisions and the choice of the analytical method can influence their decision-making. This dissertation considers three cases and examines how the choice of analytical methods influence interpretations and implications. These areas are communication for health-related information in social media, health information technology investment by hospitals as it relates to patient satisfaction, and health related expenditure policies of countries. These studies develop theoretical models and empirically test them on primary or secondary data, comparing the performance of popular analytical methods. The conduct of these three studies contributes to a better understanding about the choice of analytical methods and allow development of a heuristic approach by offering guidelines for selecting an appropriate methodology. They demonstrate the value of heuristic approaches for use with non-traditional and traditional statistical methods, as the information gained from non-traditional methods (NNs) provides insights into traditional statistical methods, similar to insights gained from exploratory data analysis. The studies also show the value in examining any dataset with multiple methods because they either confirm each other or fail to confirm, providing insights.

Three Essays on Harmony in Intrapersonal Identity Networks

Drawing attention to an under-examined process during organizational socialization, we develop theory to explain how newcomers' new organizational roles and social identities become embedded. The process of identities becoming embedded is influenced by how an individual's preexisting identities interact with new organizational identities during socialization. Perceived harmony relationships among identities indicate if newcomers experience identities interacting in a positive or negative manner generally. Using a network perspective, we suggest that the identity embeddedness of new roles and identities are indicated by: degree centrality in an intrapersonal identity harmony network, perceived harmony with the network itself, and the perceived cost of lacking harmony with a focal identity. Newcomers are likely to be more satisfied and engaged with identities with greater embeddedness as well as find such identities more salient. Organizations can work to embed their employees' new identities through initiating identity work directed towards increasing harmony perceptions among the newcomers' new organizational identities and preexisting identities. Through helping individuals create harmony relationships among identities, organizations can improve socialization outcomes.

Three Essays on Information Security Risk Management (open access)

Three Essays on Information Security Risk Management

Today's environment is filled with the proliferation of cyber-attacks that result in losses for organizations and individuals. Hackers often use compromised websites to distribute malware, making it difficult for individuals to detect. The impact of clicking through a link on the Internet that is malware infected can result in consequences such as private information theft and identity theft. Hackers are also known to perpetrate cyber-attacks that result in organizational security breaches that adversely affect organizations' finances, reputation, and market value. Risk management approaches for minimizing and recovering from cyber-attack losses and preventing further cyber-attacks are gaining more importance. Many studies exist that have increased our understanding of how individuals and organizations are motivated to reduce or avoid the risks of security breaches and cyber-attacks using safeguard mechanisms. The safeguards are sometimes technical in nature, such as intrusion detection software and anti-virus software. Other times, the safeguards are procedural in nature such as security policy adherence and security awareness and training. Many of these safeguards fall under the risk mitigation and risk avoidance aspects of risk management, and do not address other aspects of risk management, such as risk transfer. Researchers have argued that technological approaches to security risks are rarely …

Creating Supply Chain Resilience with Information Communication Technology (open access)

Creating Supply Chain Resilience with Information Communication Technology

Supply chain resilience refers to the capability of a supply chain to both withstand and adapt to unexpected disturbances. In today's turbulent business environment, firms are continually seeking to create more resilience within their supply chain through increased information communication technology use and enhanced business-to-business relationships. The focus of this dissertation is the investigation of how information communication technology creates resilience at the differing process levels of supply chain operations. Past research into information communication technology use within supply chains has often been conducted at the macro-level of supply chain phenomena. As such, there is still much to understand about how decision-makers interact with information communication technology at the micro-level of supply chain decision-making. A more in-depth, broad coverage of this interaction will provide both practitioners and academics a better understanding of how to leverage information communication technology in achieving supply chain resilience. To meet this aim, this dissertation contains three essays that re-orient conceptual thinking about supply chain phenomenon, explore how advances in information communication technology influence business-to-business relationships, and identify how information communication technology effects the decision-making of supply chain managers.

A Foot in Two Worlds: Exploring Organizational and Professional Dual Identification (open access)

A Foot in Two Worlds: Exploring Organizational and Professional Dual Identification

Who am I? Who are you? Who are we? These are some of the fundamental questions that identity scholars have grappled with since the 1900s when researchers across multiple disciplines first began to theorize about the self, identity, and identification. While the benefits and consequences of singular identities has been largely studied, recent scholars have argued for the importance of multiple identity research, as multiple identities have become increasingly salient to individuals due to societal and organizational changes including globalization and technological advancements. An important phenomenon within multiple identity research is dual identification, of which I explore a specific type– identification with both one's organization and one's profession. Using a three-study, quantitative design spanning two industries, I studied the effects of dual identification and identity conflict on individual psychological outcomes, turnover intentions, and OCB engagement. Findings from these three studies, holistically, indicate that when individuals experience identity conflict between their organizational and professional identities, they experience negative outcomes. These negative outcomes – increased emotional exhaustion, psychological distress, and turnover intentions, in addition to reduced OCB engagement – have important ramifications for the individuals themselves and their organization. However, post-hoc results indicate that dual identification – through the main effects of …

An Investigation of the Value of Bank Capital in the Context of Mergers and Acquisitions in the Banking Industry (open access)

An Investigation of the Value of Bank Capital in the Context of Mergers and Acquisitions in the Banking Industry

I analyzed a sample of 228 U.S. bank acquisitions announced from January 1996 to December 2015. This dissertation explores whether acquiring banks pay more for targets with a higher capital ratio using a better measure of goodwill than previous studies. Specifically, this study uses manually collected goodwill to evaluate the value of bank capital, a measure that I argue is superior to those used in prior studies. I collect information about goodwill for 203 merger and acquisition (M&A) deals. I find a positive relation between the target's capital ratio and the goodwill paid for targets, which is consistent with previous cross sectional analysis on the relation between bank equity capital and value. This positive relation exists in the deals with a bank target, but not when the target is a savings institution. Furthermore, I find that the positive association between the target's capital ratio and goodwill paid by the acquirer only exists in the sample of acquisitions of banks announced before the 2007 financial crisis. This dissertation also evaluates the value of bank capital by analyzing the changes in shareholders' wealth around the announcement of M&As. My empirical analysis shows that banking mergers create value for the shareholder of targets. …

Do Banks' Dividends Signal Their Financial Health? (open access)

Do Banks' Dividends Signal Their Financial Health?

This paper examines the relation between banks' dividends and their future financial health. Using banks' Nonperforming Loans Ratio, Loan Loss Provision Ratio, and Z-score as proxies for their financial health, I show that there is a strong positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter. This main finding continues to hold following several additional tests, including the application of an instrumental variable approach, the use of change in dividends as the key independent variable, the exclusion of banks that are subject to stress test, the addition of macroeconomic variables, the exclusion of too-big-to-fail banks, and the exclusion of non-depository banks. I also find that the positive relation between banks' dividends and their future financial health is more pronounced for banks with a higher degree of opacity, a lower Tier 1 capital ratio, and during the 2007-2009 financial crisis. This paper contributes to three strands of the finance literature, including the Risk Reduction Hypothesis of dividend signaling in corporate finance, bank dividend policies, and the determinants of banks' financial stability. First, I show that there is a positive relation between banks' dividends lagged by one quarter and their financial health in the …

Peeling Back the Layers of Ambidexterity in Multi-Business Firms

There is a dual accountability accepted by top executives of large multi-business firms (MBFs) to both consistently deliver performance in the short term and cultivate scalable opportunities for future growth, which requires that they be able to implement both evolutionary and revolutionary change. Researchers have defined this capability as organizational ambidexterity (OA) and deemed it a crucial requirement for every organization. Literature in the field of organizational ambidexterity (OA) describes the need to simultaneously orchestrate attention and activities along two dimensions of ambidexterity: exploitation and exploration. This dissertation peels back the layers in MBFs to generate a deeper understanding of OA in the MBF, by answering three research questions, using a mixed method approach-qualitative study followed by quantitative study: (1) What is an appropriate specification of OA in an MBF? (2) Are there differences in exploration and exploitation across the three levels within the MBF? and (3) Is there a relationship between exploration and exploitation and MBF performance at each of the three levels within the MBF? Qualitative Study 1 was conducted in December 2017, to investigate and confirm the appropriateness of the three-level operationalization of OA in MBFs. The data comprised eleven semi-structured interviews with senior executives that serve …

Small world, not small competition: does spatial distance among audit partners matter? (open access)

Small world, not small competition: does spatial distance among audit partners matter?

The purpose of my dissertation is to examine whether competition among audit partners affects audit quality. While prior research on audit market competition focuses on audit firm-level or office-level analyses, I argue that audit partners, as the primary decision makers in providing audit services, are likely to engage in competitive actions in the audit market. Further, I use spatial distance among audit partners to measure partner-level competition. I conjecture that spatial distance could better reflect the dynamics of audit market competition than the Herfindahl index, the traditional proxy for competition used in most extant studies. Drawing on the spatial economics theory and the social comparison theory, I hypothesize a negative association between competition measured by spatial distance and the quality level delivered by the incumbent audit partner. Using newly available data of U.S. audit partners, this study provides evidence that audit quality is higher (lower) when the spatial distance between the incumbent partner and the closest competing partner is larger (smaller). In addition, the results reveal that the effects of competition measured by spatial distance on audit quality is mainly a partner-level phenomenon rather than an office-level one. Overall, this study highlights the importance of studying competitive dynamics among audit …

The Determinants and Consequences of Having a Chief Operating Officer

This study examines the determinant and consequences of having a chief operating officer (COO). Specifically, we investigate chief executive officer (CEO) related factors that affect the choice to employ a COO and look into the impact of having a COO on firm operational efficiency using a data envelopment analysis (DEA)-based measure. Although prior literature has extensively investigated the role of CEOs and chief finance officers (CFOs) on firm outcomes, few studies focus on the impact of COOs. Thus, this study explores characteristics associated with the likelihood that a firm will have a COO. This research also sheds light on the effect of COOs on firm operational efficiency because the core duties of COOs include optimizing operational performance and improving cost efficiency. Our results imply that CEO busyness, CEO ability, CEO demographic characteristics, and CEO network size have a significant impact on the decision to employ a COO. We also find that firms that have a COO have a lower level of operational efficiency than firms that do not. This result implies that the cost of having a COO outweighs the benefit of having one. The effects last for three years on average. Further, we find that firms with a COO …

Impact of Market State on Momentum Portfolio Risk and Performance: A Risk-Based Explanation (open access)

Impact of Market State on Momentum Portfolio Risk and Performance: A Risk-Based Explanation

The momentum puzzle, i.e., stocks that have performed better in the past tend to perform better in the future, has been a constant challenge to classic finance theory. Prior research has failed to provide valid risk-based explanations because winner portfolios do not exhibit higher risk characteristics. Without a convincing risk explanation, the persistence of momentum profit is a violation of the efficient market hypothesis. Today, the momentum puzzle remains one of the very few major anomalies that cannot be explained by Fama-French factor models. I find prior empirical efforts to measure momentum profits and its sources are contaminated by the state of the market during both formation and holding periods. By looking into different market states, classified by both traditional and non-traditional bull and bear market definition, I find the key to at least partially solve the momentum mystery. Momentum stocks are riskier when formed in bull market, and momentum profit is much higher in continuation of market than reverses of market condition, lending empirical support to a risk-based explanation. My definition of market states is essentially based on the risk premium of major risk factors. When market risk is considered a risk factor, if realized market risk premium is …

Access to adequate liquidity to finance future investments is an essential element of financial management. The two main questions that this dissertation attempts to answer are (i) what is the net valuation effect of LoC? and (ii) if LoC create value, what are the sources of this value? To answer these questions, I constructed a sample of 85,232 firm-years spanning from 1993 to 2016, with credit line data obtained from Capital IQ and Bloomberg. I investigated the valuation effects of LoC with a methodology extensively used in the analysis of the valuation implications of cash. I used this methodology because cash and LoC are two alternatives to manage liquidity and estimated the changes in shareholders' value associated with changes in existing LoC undrawn balances and on new LoC agreements. The results from this analysis demonstrates a positive association between increases in LoC capacity and shareholder's value. These findings are also obtained in univariate and event study analyses. The results also suggest that LoC create more value for firms that are rich in cash, indicating the LoC and cash are complementary liquidity management tools. I then focused on the sources of the value created by credit lines. I examined whether information …

How is the Volatility Priced by the Stock Market? (open access)

How is the Volatility Priced by the Stock Market?

Traditional portfolio theory suggests that, in equilibrium, only the market risk is priced in the cross-section of expected stock returns. However, if the market is not perfect and investors are constantly changing investing behaviors based on their perceptions about future market outlook, then non-traditional risk factors could potentially provide significant power of describing the expected stock returns. This dissertation has two essays on the pricing of volatility, in which the market is not assumed to be frictionless or perfect. Essay 1 focuses on the pricing of individual volatility in penny stocks. Empirical results show that individual volatility plays an important role in describing the average cross-sectional returns of penny stocks. Resorting to the rolling portfolio approach, evidences indicate that portfolios consisting of penny stocks with high individual volatilities, on average, earned much higher returns than portfolios consisting of penny stocks with low individual volatilities. This effect is statistically significant when multiple factors are controlled simultaneously. Essay 2 focuses on the pricing of the market volatility among individual stocks. Following the rolling portfolio method, Essay 2 constructs portfolios that consist of individual stocks with various market volatility exposures. Traditional risk factors such as market beta, size, book-to-market, and momentum are controlled …

Who Makes the Decision? Managerial Influence on Corporate Boards and Auditor Selection, Change, and Compensation (open access)

Who Makes the Decision? Managerial Influence on Corporate Boards and Auditor Selection, Change, and Compensation

This dissertation examines whether managers influence corporate boards of directors in their auditor selection, change, and compensation decisions. This topic is important because it addresses concerns that the Sarbanes-Oxley Act of 2002 (SOX) is not effective in eliminating managerial influence over auditor engagement decisions and that it may provide a false sense of security to investors. These concerns are based on the implicit assumption that managers prefer weaker governance oversight and lower audit quality. However, empirical research testing associations between managerial influence and audit-related decisions post-SOX is scarce and generally guided by agency theory. Incorporating agency, stewardship, and resource dependence perspectives, I find that managerial preferences for auditor selection are not aligned. Specifically, CEOs positively influence the selection of higher quality auditors, whereas CFOs have the opposite effect. Further, CEOs who hold powerful roles as chairs of their companies' boards of directors appear to mitigate the negative influence of CFOs and inside directors on audit quality. CEOs serving in dual roles also oppose auditor turnover when lower earnings quality prompt higher demand for audit effort. Finally, my study provides some evidence that management exercises downward pressures on audit fees, suggesting that managers utilize their authority beyond the regulations established by …
