Walden Dissertations and Doctoral Studies
Since the topic of improving data quality has not been addressed for the U.S. defense cost estimating discipline beyond changes in public policy, the goal of the study was to close this gap and provide empirical evidence that supports expanding options to improve software cost estimation data matrices for U.S. defense cost estimators. The purpose of this quantitative study was to test and measure the level of predictive accuracy of missing data theory techniques that were referenced as traditional approaches in the literature, compare each theories’ results to a complete data matrix used in support of the U.S. defense cost …

Customer And Employee Social Media Comments/Feedback And Stock Purchasing Decisions Enhanced By Sentiment Analysis, Drew Mikel Hall
Walden Dissertations and Doctoral Studies
The U.S. Securities and Exchange Commission (SEC) warns professional investors that sentiment analysis tools may lead to impulsive investment decision-making. This warning comes despite evidence showing that aided social sentiment investment decision tools can increase accurate investment decision-making by 18%. Using Fama's theory of efficient market hypothesis, the purpose of this quantitative correlational study was to examine whether customer Twitter comments and employee Glassdoor feedback sentiment predicted successful investing decisions measured by business stock prices. Two thousand records from 3 archival U.S. public NASDAQ 100 datasets from March 28, 2016, to June 15, 2016 (79 days) of 53 companies with …
Innovation And Market Leadership In A Technology Industry, Wilson Zehr
Innovation And Market Leadership In A Technology Industry, Wilson Zehr
Walden Dissertations and Doctoral Studies
According to the Abernathy-Utterback (A-U) model, firms focus on technological product innovation early in the product lifecycle and then shift to process innovation as markets mature. However, there is no consensus on the forms that non-technological innovation can take. In addition, the A-U model, which guides innovators, does not include forms of non-technological innovation that are generally accepted by experts. In this study, a hybrid e-Delphi technique with an AHP decision model was used to evaluate the forms of innovation used to establish market leadership over the historical lifecycle of the personal computer industry in the United States. In Phase …

U.S. Corporate Energy Productivity, Greenhouse Gas Productivity, And Return On Equity, Terry Geonnie Tate
Walden Dissertations and Doctoral Studies
Corporate leaders are expected to engage in corporate social responsibility by some stakeholders, but there is no consistent evidence that corporate social performance relates to financial performance. Grounded in instrumental stakeholder theory, the purpose of this correlational study was to examine the relationship among energy productivity, greenhouse gas productivity, and return on equity. The 2016 Newsweek Green Ranking U.S. 500 was the population for this study, which consisted of the largest companies in the United States with the highest corporate social performance scores. The secondary data were collected from Newsweek.com and Morningstar.com for this study. The multiple linear regression was …

Strategies To Manage Enterprise Information Technology Projects, Mario West
Walden Dissertations and Doctoral Studies
Since 2005, most midsize company information technology (IT) projects had a 62.4% failure rate because of wrong project team communication skills or cost overruns. IT leaders expect negative IT project outcomes will cost over $2 billion by 2020. Using the actor-network theory, the purpose of this single case study was to explore strategies used by IT leaders from a midsize IT company in Washington, D.C. to plan and execute projects under budget and on time. Using purposeful sampling, 5 IT leaders were selected for this study because of their experience in implementing successful strategies for projects. Data were collected using …

Financial Statement Disclosure Of Carbon Footprint Costs In The Airline Industry, Carol Anne Tuck-Riggs
Walden Dissertations and Doctoral Studies
Unaccountable corporate polluters profit short term at the expense of global economic sustainability. The purpose of the study was to determine if carbon dioxide (CO2) penalties on the airline emissions would result in financial statement disclosure and emission mitigation. Contributing to environmental accounting, the study was based in corporate social responsibility with a conceptual framework based on economically-centered CO2 studies. A random sample of 69 global airlines, taken from the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO) memberships, was stratified between EU bound and non-EU bound airlines. The research questions explored (a) the frequency mean …
Dynamically Hedging Oil And Currency Futures Using Receding Horizontal Control And Stochastic Programming, Paul Edward Cottrell
Dynamically Hedging Oil And Currency Futures Using Receding Horizontal Control And Stochastic Programming, Paul Edward Cottrell
Walden Dissertations and Doctoral Studies
There is a lack of research in the area of hedging future contracts, especially in illiquid or very volatile market conditions. It is important to understand the volatility of the oil and currency markets because reduced fluctuations in these markets could lead to better hedging performance. This study compared different hedging methods by using a hedging error metric, supplementing the Receding Horizontal Control and Stochastic Programming (RHCSP) method by utilizing the London Interbank Offered Rate with the Levy process. The RHCSP hedging method was investigated to determine if improved hedging error was accomplished compared to the Black-Scholes, Leland, and Whalley …

Relative Pricing Of Publicly Traded U.S. Electric Utility Companies, Nicholas Stephen Jewczyn
Walden Dissertations and Doctoral Studies
In the financial turmoil of 2008, U.S. firms reported debt-ratios that differed from the debt-ratios calculated from balance sheets. The problem is that investors bought common stock expecting initial investment return and lost money when companies delisted. The purpose of this quantitative study was to determine sample securities pricing with the application of synthetic assets and debt accrued. Addressed in the research questions was whether those securities were (a) underpriced compared with return-on-assets (ROA), (b) overpriced compared with ROA, (c) a debt-ratio higher than 60% and also overpriced, (d) underpriced with a synthetic asset added, or (e) related by relative …
