Stochastic Modeling Of Earthquakes And Option Pricing Using Bns-Gamma-Ou Model, Mandela Bright Quashie

Open Access Theses & Dissertations

High frequency data are becoming increasingly popular these days. They are fundamental in basically every facet of people’s lives. They are the determining factors in hedging in the field of finance. In geology, they help in the accurate prediction of earthquakes’ magnitude which goes along way to help save lives and properties.

High frequency data are also used more and more frequently for speculations. For this reason, it is important not only for scientists to apply models allowing correct quantification of these data, but also to improve the eciency of these models.

The Black-Scholes model, which is widely used because …

Who Is Willing To Speak Up And Why? Examining Individual And Organizational Predictors Of Employee Voice Behavior In Higher Education Institutions, Jessie Socorro Arellano

Open Access Theses & Dissertations

Employee voice behavior is central to the effectiveness, the development, and the adaptability of organizations to their environments. However, there is currently limited organizational research and knowledge on the factors that influence employee voice behaviors, especially in the context of higher education institutions. As such, the purpose of this study is to examine the predictors of employee voice behaviors in institutions of higher education. Specifically, this study examines the impact of key individual and organizational factors such as alumni status, organizational commitment, work motivation, communication climate, and organizational politics on employees' expression of promotive and prohibitive voice in higher education …

Lévy Processes: Characterizing Volcanic And Financial Time Series, Peter Kwadwo Asante

Open Access Theses & Dissertations

In this work, we use the Diffusion Entropy Analysis (DEA) to analyze and detect the scaling properties of time series from both emerging and well established markets as well as volcanic eruptions recorded by a seismic station, both financial and volcanic time series data are known to have high frequencies (i.e they are collected at an extremely fine scale). The objective is to determine the characterization i.e whether they follow a Gaussian or Lévy distribution. If they do follow a Lévy distribution we are then interested in finding if they are characterized by a Lévy walk which has a finite …

Proprietary Costs Of Financial Reporting, Country-Level Attributes, And Financial Statement Comparability, Jangho Gil

Open Access Theses & Dissertations

This study investigates the impact of country-level attributes on the relationship between proprietary costs of financial reporting and financial statement comparability. Given that managers use discretion in financial reporting, proprietary costs of financial reporting and country-level attributes could play a role in shaping managers' financial reporting behavior, which, in turn, could have an impact on financial statement comparability. For international study, I use four country-level latent factors, suggested by Isidro et al. (2019), that categorize most country-level features that affect financial reporting practices. I find that the negative relationship between proprietary costs and comparability is stronger in countries with relatively …

Achieving Effectiveness And Innovation In U.S. Public Organizations Through Ability-Enhancing And Opportunity-Enhancing Soft/Commitment High Performance Work Practices, Kingshuk Saha

Open Access Theses & Dissertations

It is well-established in the management literature that HPWPs improve productivity in the private sector. But does HPWPs work in the public sector? A thorough literature search revealed only 45 HPWPs studies done in the public sector. The first purpose of this Dissertation is a thorough literature review of these 45 studies. Out of these 45 studies, only 12 had samples obtained from the U.S. Hence, it can be argued that there is much to be discovered about HPWPs in the U.S. public sector. The second purpose of this Dissertation is to categorize HPWPs in the U.S. public sector based …

Essays On The Spillover Effects Of Whistleblowing On Peer Firms, Emmanuel Joseph Sequeira

Open Access Theses & Dissertations

This Dissertation examines the spillover effects of media reported corporate whistleblowing on industry peer firms in two essays. The first essay examines peer firm risk-taking and firm efficiency following a whistleblowing allegation. I find that peers significantly reduce their risk-taking following the allegation. They also increase their efficiency following the allegation and increase their market share at the expense of the whistleblowing firms, leading to increased profitability. My second essay examines peer firms' earnings management choices following a whistleblowing allegation. I find that peer firms significantly reduce their manipulation of real activities and reduce their use of accruals-based earnings management …

Managerial Entrenchment And Financial Reporting Comparability, Qifeng Wu

Open Access Theses & Dissertations

This study examines whether managerial entrenchment has an association with firms' financial statement comparability. I find that managerial entrenchment has a significant negative association with financial statement comparability, providing a new notion about the management influence on financial reporting quality. Moreover, by using the business segment as a proxy for business complexity, I find that the variation of accounting comparability with its peer firms mainly stems from managers' investment choice. This finding supports FASB's assertion that financial statement comparability is a reporting quality that should be enhanced among firms with similar economic events. Lastly, I test if managerial entrenchment mitigates …

Target Accounting Quality And Merger Consideration Design, Yuyun Zhou

Open Access Theses & Dissertations

This study examines how accounting quality of target firms relates to the design of merger consideration in acquisition agreements. Prior literature suggests that acquirers mitigate adverse selection problems by making the value of merger consideration sensitive to the acquirers' merger announcement returns. Using a large sample of acquisition agreements of public merging parties between 1996 and 2017, I investigate whether high-quality accounting information of target firms helps acquirers mitigate adverse selection problems and in turn affects the sensitivity of merger consideration to the acquirers' merger announcement returns. I hypothesize and find that accounting quality of target firms is negatively related …

A Social Network Perspective Of Employee Overqualification To Outcomes Relationships In Workgroups, Farid Jahantab

Open Access Theses & Dissertations

Integrating overqualification research with the social network perspective, and emphasizing social exchanges among organizational members, I propose to examine how social networks unpack the relationship between perceived overqualification and organizational outcomes. Specifically, I suggest that perceived overqualification (POQ) has implications for employees' centrality in a friendship network and that friendship network centrality (FRDNC) mediates the relationships between perceived overqualification and organizational outcomes (operationalized as organizational citizenship behaviors directed at coworkers [i.e., OCBI] and turnover intentions). Further, adopting a contingency approach to overqualification, I propose to identify contextual variables that determine the strength of perceived overqualification-social network-outcomes relationships. Social comparison theory …

Market Effects Of Local Media Employment Reductions On The Idiosyncratic Risk Of Nearby Firms; Returns, Valuation, And Debt; And Firm Meet-Beat Behavior And Ceo Turnover And Compensation, C. Kyle Jones

Open Access Theses & Dissertations

This research examines the effects of reductions in local and regional media employment on firms' information environment. A reduction in the number of local media employees available to provide coverage of firms is associated with persistent levels of increased idiosyncratic risk. The source of that firm-level risk appears to be increased estimation risk among investors, rather than decreased awareness about the investment opportunities or real effects on firms' product market competition. I also demonstrate that overall levels of local media coverage are associated with differences in returns similar to those associated with coverage in national outlets. While a reduction in …

Two Essays On Executive Compensation, Michael Abrokwah

Open Access Theses & Dissertations

This doctoral dissertation examines the effect of an exogenous event on Executive compensation and the relationship between executive compensation and earnings management undertaken by the firm.

My first essay presents evidence that natural disasters have an effect on CEO compensation. Our main findings are that option compensation is lower for CEOs in counties where a natural disaster occurred. Furthermore, in the year of the disaster, stock compensation is higher among CEOs in natural disaster counties when compared to those in non-disaster counties. When considering liquidity, option compensation levels are lower for firms with below average liquidity levels but stock compensation …
