The Value-Relevance Of Nonfinancial Information: The Biotechnology Industry, Ya-Wen Yang

Doctoral Dissertations

This study examines whether nonfinancial patent information is useful to investors in assessing and valuing biotech firm’s long-term financial performance. The biotech industry requires large R&D investments with uncertain payoffs. Current accounting practice expenses (rather than capitalizes) R&D expenditures. As a result, financial variables are often negative or excessively depressed. Because accounting assets do not reflect biotech firms’ valuable intangible assets, this study examines whether nonfinancial patent information supplement the information content of financial information in market valuation. Using six patent variables measuring both quantity and quality aspects of patents, I found evidence consistent with the idea that nonfinancial patent …

Interfirm Demand Integration: The Role Of Marketing In Bridging The Gap Between Demand And Supply Chain Management, Teresa M. Mccarthy

Doctoral Dissertations

As firms increasingly outsource functions to focus on core competencies, access to resources from trading partners to accomplish goals becomes more important. As such, supply chain management is recognized as critical to creating and sustaining competitive advantage by integrating activities across trading partners that can produce a unique and valuable offering. This dissertation suggests the role of marketing is well positioned to oversee and manage integration of supply and demand activities that have traditionally been practiced separately both within and across firms in a supply chain. The research fills a gap in the literature by presenting a comprehensive model of …

Theory And Construction Methods For Large Regular Resolution Iv Designs, Robert M. Block

Doctoral Dissertations

We define 2k-p fractional factorial designs which use all of their degrees of freedom to estimate main effects and two-factor interactions as second order saturated (sos) designs. We prove that resolution IV sos designs project to every other resolution IV design, and show the details of these projections for every n = 32 and n = 64 run fraction. For k > (5/16)n, all resolution IV designs are a projection from the even sos design at k = n/2. For k ≤ (5/16)n the minimum aberration design resolution IV designs are projections of sos designs with both even and odd words …

The Effect Of Brand Equity In Supply Chain Relationships, Donna F. Davis

Doctoral Dissertations

A systematic review of the marketing literature on brands reveals very few studies devoted to understanding brands in interorganizational exchange; however, the failure to successfully manage relationships with supply chain partners is now seen as a potentially fatal obstacle to the success of a brand (Shocker, Srivistava and Ruekert 1994). Focusing exclusively on managing the brand in consumer markets ignores the needs of important downstream customers such as distributors and retailers and fails to capitalize on the potential for leveraging brand equity to create added value with upstream suppliers.

A multiple method approach was used to explore the phenomenon of …

An Examination Of Interorganizational Relationship Magnitude And Its Role In Determining Relationship Value, Susan L. Golicic

Doctoral Dissertations

As the business environment becomes more complex, organizations within a supply chain realize that in many instances they can benefit from closer, long-term relationships. However, researchers in this area agree that there is no one relationship that is appropriate or necessary for all situations. Since there exists a wide range of relationships within a supply chain, businesses need to manage the development and maintenance of each relationship in their “portfolios.” This entails recognizing the motivating factors that drive companies to a particular relationship, determining the appropriate amount of resources that will be dedicated based on the targeted relationship, and measuring …

Bayesian Analysis Of Threshold Autoregressive Models, Yongjae Kwon

Doctoral Dissertations

Threshold Autoregression is a powerful statistical tool for modeling structural nonlinear relationships. This study presents a Bayesian modeling procedure for threshold autoregressions. To this end, the analytical framework of Bayesian analysis for a univariate SETAR and a threshold VAR were developed. For the estimation of parameters, a Markov-Chain Monte Carlo (MCMC) simulation and an importance/rejection sampling are used to obtain posterior samples. In model determination, this study shows that Bayes factors are reliable testing procedures in model comparison, lag order selection, and threshold nonlinearity tests. However, it is difficult to get the exact figure of a Bayes factor because the …

Competition And Contestability In Central And Eastern European Banking Markets, H. Semih Yildirim

Doctoral Dissertations

This study attempts to analyze the effects of financial liberalization and deregulation on competitive conditions in the banking industries of fourteen Central and Eastern European (CEE) transition economies using firm-level data for the period 1993-2000. The basis for the evaluation of competitive situation is the extant oligopoly theory in the new industrial organization literature, specifically, the competition model developed by Rosse and Panzar (1977), and Panzar and Rosse (1982,1987). This approach relies on the premise that, in their long-run equilibrium, banks will employ different pricing strategies in response to a change in input costs depending on the market …

Testing The Effectiveness Of Deregulation In The Electric Utility Industry: A Market-Based Approach, Manfen Wang

Doctoral Dissertations

In this paper, I investigate one stated purpose of deregulation in the electric utility industry—to make utility operations more responsive to news releases, a proxy for market forces. My premise is that utilities providing electricity to highly deregulated states will be more responsive to market forces than those providing electricity to non-deregulated states. I employ intraday data from April to June 2001, the year after deregulation, and from 1994, the year before deregulation. I also employ the Brown-Forsythe-Modified Levene (BFL) test to determine the volatility differences between days with released news and days without released news. The results of BFL …

Antecedents Of Salesperson Effectiveness And Efficiency Performance: A Data Envelopment Analysis, Xueming Luo

Doctoral Dissertations

The objective of this dissertation was to (1) measure salesperson efficiency; (2) investigate both personal and organizational factors that determine salesperson efficiency; and (3) investigate both personal and organizational factors that determine salesperson effectiveness. Salesperson efficiency was assessed by data envelopment analysis (DEA). Two different DEA models were employed in order to increase the reliability of the efficiency results. Antecedents of salesperson efficiency and effectiveness were tested using Tobit regression analysis and ordinary least square regression analysis, respectively. These antecedents include not only personal level variables such as working smart, working hard, learning goal orientation, and performance goal orientation, but …

Cultural Diversity's Impact On Firm Performance: The Moderating Influence Of Diversity Initiatives And Socialization Tactics, Amy Mcmillan-Capehart

Doctoral Dissertations

The primary purpose of this dissertation is to test the hypothesized relationships between cultural diversity and firm performance. Specifically, this dissertation examines whether or not socialization tactics and diversity initiatives moderate the relationship between diversity and firm performance. This dissertation uses ROA, ROE, and employee productivity in order to capture an accurate picture of firm performance.

My second purpose is to test competing hypotheses that are based on different theories. Theories relating to diversity suggest that there may be both positive and negative effects of a heterogeneous workforce. Therefore, it is necessary to isolate those instances in which diversity can …
