Consequences of Coworker Bullying: A Bystander Perspective

Description: Previous research on workplace bullying primarily focuses on two main actors – the bully and the victim – while neglecting a third actor: the bystander of the bullying. The prevalence of workplace bullying is increasing across organizations, resulting in more employees becoming subjected to the effects of workplace bullying. Furthermore, witnessing coworker-on-coworker bullying is likely to influence the relationships that the bystander has with the two coworkers involved in the bullying episode. Two areas are proposed to investigate their effect on the coworker bystander: coworker interpersonal justice and personal identification with coworkers. Coworker interpersonal justice involves the perceived fairness between coworkers, while personal identification refers to how these bystanders identify with the specific actors of the bullying event. In addition to work-related outcomes, bystanders are affected at a personal level. That is, being exposed to bullying situations causes these bystanders to alter their anxiety levels and their core affect, with core affect being a precursor to moods and emotions. In addition to the aforementioned outcomes of witnessing a coworker bullying incident, there are also contextual aspects which may influence these relationships. Personal-level factors, such as a bystander's empathy and sense of coherence (i.e., coping mechanisms), may influence the effect of witnessing a coworker being bullied. Similarly, the gender of the victim in relation to the gender of the bystander may also play a role. Using affective events theory, I investigate how witnessing coworker bullying in the workplace effects bystanders. This research employs a 2 x 2 experimental design with multi-wave data collection and an in-person lab session to test the proposed hypotheses. AET is operationalized by creating a fictional coworker bullying situation in which observers are either exposed to the bullying situation or not. This research offers several contributions to the management literature as well as to practitioners. First, it ...

Cooperative Strategy and Sources of Knowledge Integration Capability and Innovation: A Relational View

Description: Faced with the challenges to addressing the novelties of the changing business environments (e.g., new customer requirement, changes in customers taste and preferences, the introduction of new products or services by competitors), organizations seek to build collaboration among their employees who possess complementary knowledge. Integrating complementary knowledge enhances employees' ability to address environmental challenges and foster innovation. Despite the importance of knowledge integration for innovation, integration of such knowledge becomes difficult when employees lack a shared understanding of knowledge, and when the knowledge is newly generated. Because new knowledge is tacit in nature and highly personal to a particular individual, it is difficult to articulate, making knowledge integration (KI) an arduous task. Lack of shared understanding, the presence of new knowledge, and lack of common interests in employees creates three types of knowledge boundaries – syntactic (information processing) boundaries, semantic (interpretive) boundaries, and pragmatic (political) boundaries. The presence of knowledge boundaries makes it difficult for employees to share and access their knowledge with each other. To overcome the challenges related to the knowledge boundaries, employees use boundary-spanning objects, which are common lexicons, common meaning, and common interests, to share and access their knowledge across the boundaries. Although prior studies have emphasized the importance of knowledge integration of various knowledge sources for innovations, examinations of what enhances KI capability of employees for organizational innovation remain limited. In addition, apart from Carlile, (2004) and Franco (2013), which are both case studies, other studies that examine the role of boundary spanning objects for knowledge integration are missing. The knowledge management literature also fails to measures (the success of common lexicons, common meaning, and common interests for achieving KI capability) boundary spanning objects. Therefore, in this study, new measurement items of boundary spanning objects and novelty are developed to test the hypotheses. A survey-based ...

Semiglobalization: Institutional Effects on Multilatina Cross-border Acquisitions

Description: The internationalization research domain has predominantly focused on country level antecedents of firm level decisions, with particular emphasis on why certain countries are selected over others for foreign direct investment (FDI). This approach may oversimplify what actually occurs from both practical and research perspectives. Recently, MNE strategic orientation and conduct, as an outflow of a region-based localization perspective (i.e.,semiglobalization), has gained increased scholarly attention. The tradition of considering country level institutional environments may be more robustly informed by extending a paradigm which considers region-based institutions, in addition to country. Thus, in this study I examine institutional effects, as underpinned by institutional theory, on one segment of FDI decision making, cross-border acquisitions behavior, in an understudied context, Latin American MNEs (i.e., Multilatinas). Linear and mixed regression are used to test hypotheses, by examining a sample of all Multilatina CBAs exacted over a five year period (2007-2011)in targeting host country firms within eight geographic regions. Multilevel study results provide overarching support for hypotheses, that a Multilatina's internationalization into a country and region through cross-border acquisition equity participation is influenced by both country and region institutional environments. Contributions are made to the semiglobalization, cross-border acquisitions, institutions, and Multilatina literature streams through development of a more robust, multilevel perspective which more accurately captures how MNEs consider institutional environments in their international strategy and conduct.

Virtual Entrepreneurship: Explicating the Antecedents of Firm Performance

Description: Prior research has examined entrepreneurial businesses spatially located in the physical or offline context; however, recent radical information and technological breakthroughs allow entrepreneurs to launch their businesses completely online. The growth of the online business industry has been phenomenal. Predictions for worldwide online sales estimate it to reach $2 trillion in 2016. Virtual entrepreneurship refers to the pursuit and exploitation of opportunities via virtual platforms. Web 2.0 cybermediaries offer web-based platforms that function similarly to traditional intermediaries in a virtual setting and minimize barriers to entry for virtual entrepreneurial firms. The use of such cybermediaries with increasing success suggests an implicit shift in the dominant logic that typically underpins the functioning of entrepreneurial firms operating in the physical world. In this relatively uncharted territory, marked by a focus on profit, cooperation, collaboration and community, three ideal-type institutional logics i.e. Market, Corporation and Community, blend together. It is posited that a Virtual Entrepreneurial Logic guides the norms, behaviors, and practices of entrepreneurial firms operating via these virtual platforms. This raises the question whether the blending of three ideal-type logics leads to the existence of different antecedents of performance. A business model antecedent addressing the economic dimension, a community antecedent addressing the community dimension and a co-creation antecedent addressing the collaborative dimension of the Virtual Entrepreneurial Logic were therefore empirically examined in this study. Thus, three research questions were investigated to explicate the antecedents. Primary data from 1396 virtual entrepreneurial firms was collected (business model antecedent n=366, community antecedent n=732 and co-creation antecedent n= 298) to test the proposed hypotheses. Results provided support for the three antecedents. This study makes important theoretical and practical contributions to understanding the domain of virtual entrepreneurship from a blended logics perspective. Using the theoretical lens provided by institutional logics helps shed light on the pivotal role ...

Incumbent Response to Radical Technological Innovation: the Influence of Competitive Dynamics on Strategic Choice

Description: Prior research on incumbent firm response to radical technological innovation identifies firm, technology, and environmental factors associated with incumbents’ performance after a technology shift. What remains unexplored are factors affecting choice of response made before a technological shift occurs. Such ex ante choices are important intermediate outcomes affecting long-term performance outcomes. Competitive considerations may be influential inputs in choice processes because technological innovation is often related to competitive strategy. The resulting research question for this study is: What role do competitive considerations play in incumbent firms’ ex ante strategic choices in response to potentially radical technological innovations? Findings from a survey of key informants in the electronics industry whose firms face a potential technological disruption (n=120) suggest that incumbents’ response choices are affected by competitor-related orientations and by perceptions of relative strength of their strategic assets. Limited support is found for a moderating effect of perceptions of the competitive environment. The results of this study extend theory on incumbent response to radical technological change by shedding light on the influence of competitor interdependence. Findings also suggest the importance of strategic choice as an intermediate variable in understanding incumbents’ long-term performance. Research examining choice factors at varied stages of a technology’s diffusion can further advance understanding of the evolving nature of strategic response choices and the effects they have on long-term performance.

Unethical Prosocial Behavior: Theory Development and Experimental Findings

Description: Job performance has historically been divided into two subsets, that which is prescribed and that which is discretionary. Further, discretionary workplace behavior has typically been described as either helpful or ethical (i.e. organizational citizenship behavior) or harmful and unethical (i.e. workplace deviance behavior) with behavior that is both helpful and unethical rarely discussed. I term this lesser discussed type of discretionary workplace behavior unethical prosocial behavior and define it as discretionary actions that are intended to benefit a specific referent outside the self, either an individual or a group, that are illegal and/or morally inappropriate to larger society. In addition to defining unethical prosocial behavior, this paper places the behavior in an organizing framework of discretionary workplace behaviors and tests several hypotheses regarding unethical prosocial behavior. The hypotheses address three primary research questions. First, are there contextual conditions that make it more likely that a person will engage in unethical prosocial behavior? Second, does the nature of the relationship between the actor and the beneficiary make unethical prosocial behavior more or less likely? And third, are there individual characteristics that serve to either constrain or enhance the likelihood that and individual will engage in unethical prosocial behavior? A 2 x 2 experimental design was used to test these hypotheses. As expected, in-group (vs. out-group) salience increased the likelihood of UPB. Individuals in the in-group condition engaged in significantly greater UPBs than those in the out-group condition. Contrary to expectations, shared reward (vs. no reward) decreased the likelihood of UPB. Individuals who were due a reward engaged less in UPBs than those who were not due a reward. Possible explanations for this relationship (both methodological and theoretical) are explored. While the overall effect of reward structure on UPB was in the opposite direction from that which was expected, propensity to morally ...

Explicating the Managerial Processes of Dynamic Capabilities and Investigating How the Reconceptualized Construct Influences the Alignment of Ordinary Capabilities

Description: In the last three decades, strategic management scholars have explored the organization’s need to reconfigure its capabilities to leverage opportunities in a changing environment. The first objective of this study was to identify the underlying elements of the managerial processes of dynamic capabilities, and to offer a reconceptualization of the dynamic capabilities construct. The second objective of this investigation was to determine how the reconceptualized dynamic capabilities construct could influence the alignment of ordinary capabilities. Findings from this investigation indicate that organizational processes and managerial processes are unique components of dynamic capabilities. In addition, these organizational processes were found to be significantly and positively correlated with the alignment of ordinary capabilities. Furthermore, managerial processes were found to moderate the relationship between organizational processes and one type of ordinary capability alignment (i.e. innovation-operations capability alignment). Taken together, the findings of this study support the notion that dynamic capabilities are context specific, and that understanding how they influence the organization’s ability to change is complex. The developments and findings in this study offer a reconceptualized and empirically tested framework for the capability alignment process, thereby providing a more comprehensive picture of the underlying processes.

The Value of Ties: Impact of Director Interlocks on Acquisition Premium and Post-acquisition Performance

Description: Mergers and acquisitions (M&A) evolved as alternative governance structures for firms seeking to combine resources with other firms, access larger markets, or acquire strategic assets. In spite of managers’ enthusiasm about the practice, studies show mixed results regarding post-acquisition performance of acquiring firms. The impact of acquisitions on the performance of acquiring firms has therefore remained inconclusive. A few reasons for this have been suggested and recent meta-analytic research efforts indicate that studies in M&A may have ignored variables that have significant effects on post-acquisition performance. In a bid to extend the literature on M&A and identify cogent variables that impact on acquisition performance, this dissertation draws on social network theory to advance a proposition for the value-of-ties. This was done by examining the impact of directorate interlocks on acquisitions specifically and organizational strategy in general. A non-experimental cross-sectional study of 98 interlocked directorate companies simultaneously involved in acquisitions was conducted. Several multiple regression analyses were conducted and the results obtained suggest that there is a positive linear relationship between director interlocks and post-acquisition performance and that to some extent this relationship is moderated by acquisition experience. The study also showed that director interlocks have a negative linear relationship with acquisition premium. This study complements the body of knowledge on acquisitions and network theory. It also successfully combined a multi-level approach to research on organizations and strategic management.

When and Where Does It Pay to Be Green: Intra- and Inter-organizational Factors Influencing the Environmental/Financial Performance Link

Description: Managers are coming under increasing pressure from a wide array of stakeholders to improve the environmental performance of their firms while still achieving financial performance objectives. One of the most researched questions in the business and the natural environment (B&NE) literature is whether it pays to be green. Despite more than three decades of research, scholars have been unable to clearly answer this question. The purpose of this dissertation was to attempt to identify the antecedents that lead to increased, firm-level environmental performance and the conditions in which firms are then able to profit from enhanced environmental performance. First, I assessed three intra-organizational factors of top management teams (i.e. female representation, concern for non-financial stakeholders, and risk-seeking propensity) that theory indicated are associated with increased corporate environmental performance (CEP). Theory also leads us to believe that top management teams with these attributes should perform better in dynamic settings, so I tested to see if industry dynamism moderates these relationships. Second, I then examined industry-level forces that theory indicates would moderate the relationship between CEP and corporate financial performance (CFP). These moderating forces include industry profitability, industry dynamism, and the degree of industry environmental regulation. Hypotheses were tested using panel data obtained from the KLD, Compustat, and Environmental Protection Agency databases for the years 2000 to 2011. The sample consists of firms comprising the Standard and Poor’s 500 and was analyzed using fixed-effect regression and moderating variables were analyzed using the Johnson-Neyman technique.

Psychological Diversity Climate and Its Effects: the Role of Organizational Identification

Description: Organizations have begun to focus heavily on diversity. As a result, organizations spend time and resources creating diversity policies and investing extensively in diversity training programs. While an abundance of research exists on demographic diversity, research has just begun to incorporate employees’ perceptions of diversity as an influential factor affecting organizationally relevant employee outcomes. Employees are a crucial reference in understanding whether organizations benefit from engaging in such actions. The purpose of this study is to examine the influence of diversity climate on employees’ organizational identification. Furthermore, I investigate how organizational identification mediates the relationship between diversity climate perceptions and outcomes including turnover intentions, job satisfaction, and organizational citizenship behavior. I refine our understanding by identifying personal characteristics that influence the diversity climate (PDC) – organizational identification (OID) relationship. This research offers several contributions to management literature and scholars as well as practitioners. First this study empirically examines the relationship between PDC and OID. This connection is important as it identifies the psychological mechanism linking PDC to subsequent outcomes as well as showing how positive climate perception can influence an employee’s sense of belonging. The second contribution is the in-depth identification of personal characteristics and their role in this relationship specifically, demographics, values, and attachment to demographic category. Individuals will differ in their beliefs and thus their attachment based on climate perceptions. Finally, this study links diversity climate to organizationally relevant outcomes through organizational identification.

Social Innovation in Venture Capital Firms: Strategy, Structure, and Performance

Description: Social innovations are solutions related to humanistic needs and the betterment of mankind with the intent of creating social value and eventual societal level changes. Social innovation therefore broadens traditional views of innovation to include processes of societal transformations and human behaviors. These social innovations are becoming more commonplace across all sectors, including capital markets. Private equity and venture capital firms in the capital markets sector engage in social innovation by investing capital with the goal of delivering both economic and social value. Despite the critical importance of venture capital (VC) in the success of social innovations through socially responsible investing, there is a paucity of research in understanding the factors that affect the performance of these social VC firms. This research gap is addressed by asking the following primary research question: What is the role of strategic and structural factors in the performance of socially innovative venture capital firms? The firm level research is theoretically based on the well-established design school. This framework highlights the overarching importance of strategy and structure in the accomplishment of firm goals. In the context of the venture capital industry, it was hypothesized that certain unique strategic and structural factors (i.e., stage of investment, age, size, and network relationships) would influence the performance of socially innovative VC firms. A moderated mediation model was proposed to examine these factors and their influence on performance variation. The sample of socially innovative VC firms was generated from the ThomsonOne Private Equity Database. The research design and methodology followed a systematic and objective process. This included identification of the sample of 381 VC firms, collection of mission statements for each VC firm, development of key word list pertaining to social innovation for content analysis and the collection of archival data on each VC firm. Content analysis was then ...

An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes

Description: To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the data with the expectation that there would be significant differences in the two styles of leadership such that each explains unique variance in follower behavior. The results of this dissertation support the lack of perceptual difference between the two theories of leadership. The results of this experiment do not come completely unexpected because of the ethical overlap between the two styles of leadership. Although subjects in the experiment could differentiate authentic leadership from transformational leadership based on the manipulations, authentic leadership effects were not significantly different when compared to transformational leadership effects. As a result, analyses in my research do ...

A Study of Effective Leadership in the Chinese Context

Description: Leadership has attracted a significant amount of scholarly attention in the past few decades. However, most research and theory contributions are to a great extent limited to accounting for leadership practices in the West (Littrell, 2002). This study is designed to develop an effective leadership model that works in the Chinese context. Paternalistic leadership, a dominant leadership style in an Eastern business environment, is compared with transformational leadership, a dominant leadership style in a Western business environment. The notion of transformational leadership was developed under the tutelage of Bernard Bass (1998). Transformational leadership is found to be compatible with collectivistic values (Walumbwa & Lwwler, 2003) and is believed to be appealing and generalizable to Chinese leadership situations (Chen & Farh, 1999). Other researchers have found that within Chinese organizations, leader behaviors are quite distinct from transformational leadership, referring to this leader style as paternalistic leadership (Redding, 1990; Cheng, 1995). The questions are asked, “Transformational or paternalistic leadership, which one is more effective in Chinese organizations? Is one type of leadership superior to the other one in the Chinese culture?” To answer these questions, a model is proposed to clarify the mediating effects of trust and harmony on the relationship between leadership style and its effectiveness, and to interpret the moderating effects of generation on the relationships between both paternalistic and transformational leadership with trust and harmony. Most theories of leadership in organizational behavior originated in the United States and Western Europe and are hypothesized to be universally applicable to non-Western contexts. Departing from this tradition, the current study proposes a Chinese culture-specific leadership theory, built on traditional Confucianism. The principle aim is to examine and articulate a culturally informed and warranted ground for a leadership model in the Chinese context. The results of the study provide a new perspective on ...

Absorptive Capacity: An Empirical Examination of the Phenomenon and Relationships with Firm Capabilities

Description: The field of strategic management addresses challenges that firms encounter in an attempt to remain competitive. The ability to explain variation in firm success through examination of knowledge flows has become a prominent focus of research in the strategic management literature. Specifically, researchers have sought to further examine how firms convert knowledge, a phenomenon conceptualized as absorptive capacity. Absorptive capacity is the firm’s ability to acquire, assimilate, transform, and exploit knowledge. Few studies have captured the richness and multi-dimensionality of absorptive capacity, and it remains to be understood how the dimensions of the phenomenon convert knowledge. Furthermore, how absorptive capacity influences the firm remains to be understood. To address these research gaps, this dissertation seeks to (1) determine how absorptive capacity converts knowledge, and (2) determine how absorptive capacity influences firm capabilities. The research questions are investigated using structural modeling techniques to analyze data collected from software-industry firms. The findings offer contributions to the absorptive capacity and capability literatures. For example, absorptive capacity is hypothesized to consist of complex relationships among its internal dimensions. However, findings of this study suggest the relationships among the dimensions are linear in nature. This finding is in line with the theoretical foundations of and early literature on absorptive capacity but contrary to recent conceptualizations, which suggests relationships among the dimensions are more closely related to the theoretical origins of absorptive capacity. Additionally, to examine how absorptive capacity influences the firm, a capability-based perspective is used to hypothesize the influence of absorptive capacity on firm capabilities. Findings suggest absorptive capacity positively influences each dimension of firm capabilities (e.g., operational, customer, and innovation capabilities); thus, absorptive capacity influences the firm by altering firm capabilities. Given the richness of the findings, numerous fields are likely to benefit from this investigation. Through an examination of absorptive capacity and ...

An Emotional Business: the Role of Emotional Intelligence in Entrepreneurial Success

Description: Successful entrepreneurial activity is important for a healthy economy and can be a major source of job creation. While the concept of entrepreneurship has been around for quite some time, researchers continue to explore the factors that underlie entrepreneurial performance. Specifically, researchers have sought to further examine why some entrepreneurial ventures are more successful than others. the concept of emotional intelligence (EI) has gained the attention of researchers and practitioners alike. Practitioners have realized that employees can no longer be perceived as biological machines that are capable of leaving their feelings, norms, and attitudes at home when they go to work. Researchers are embracing the concept of emotional intelligence because of its relationship with efficiency, productivity, sales, revenues, quality of service, customer loyalty, employee recruitment and retention, employee commitment, employee health and satisfaction, and morale. While there is considerable evidence documenting the effects of emotional intelligence on leadership performance, job performance in large firms, and educational performance, very little research has examined how emotional intelligence affects entrepreneurial performance and the variables that account for this relationship. Individuals in entrepreneurial occupations face business situations that necessitate unique skills and abilities in social interactions. Emotional intelligence has implications for entrepreneurial situations and social interactions such as negotiation, obtaining and organizing resources, identifying and exploiting opportunities, managing stress, obtaining and maintaining customers, and providing leadership. the primary purpose of this study is to investigate emotional intelligence in the context of entrepreneurship. in addition, the study will shed light on the mediating effects of individual competencies, organizational tasks, and the environmental culture and climate. the results of the study provide insights for emotional intelligence researchers, entrepreneurship researchers, individuals with entrepreneurial aspirations, academic institutions, as well as government and financial entities that provide resources to new ventures.

High Risk Occupations: Employee Stress and Behavior Under Crisis

Description: The purpose of this study is to analyze the relationships between stress and outcomes including organizational citizenship behavior (OCB), job satisfaction, and burnout in high-risk occupations. Moreover, how personality, emotions, coping, and leadership influence this relationship is investigated. Data were collected from 379 officers in 9 police organizations located in the Southern and Southwest United States. The primary research question addressed within this dissertation is: What is the relationship between stress and behavioral and affective outcomes in high-risk occupations as governed by coping, leadership, and crisis? The majority of the hypothesized relationships were supported, and inconsistencies center on methodological and theoretical factors. Findings indicate that occupational stressors negatively influence individuals in high-risk occupations. Moreover, crisis events exacerbate these influences. The use of adaptive coping strategies is most effective under conditions of low stress, but less so under highly stressful circumstances. Similarly, transformational leader behaviors most effectively influence how individuals in high-risk occupations are affected by lower, but not higher levels of stress. Profiles of personality characteristics and levels of emotional dissonance also influence the chosen coping strategies of those working in high-risk occupations. Prescriptively, it is important to understand the influences among the variables assessed in this study, because negative outcomes in high-risk occupations are potentially more harmful to workers and more costly to organizations. Thus, this dissertation answers the research question, but much work in this area remains to be done.

Examining Curvilinearity and Moderation in the Relationship between the Degree of Relatedness of Individual Diversification Actions and Firm Performance

Description: Corporate diversification continues to be an important phenomenon in the modern business world. More than thirty years of research on diversification suggests that the degree of relatedness among a firm's business units is a factor that can affect firm performance, but the true effect of diversification relatedness on firm performance is still inconclusive. The purpose of this dissertation is to shed more light on this inconclusive association. However, attention is focused on the performance implications of individual diversification actions (e.g., acquisitions and joint ventures) rather than on the overall performance of firms with different levels of diversification. A non-experimental, longitudinal analysis of secondary data was conducted on over 450 unique acquisitions and on more than 210 joint ventures. Results suggest that even when individual diversification actions rather than entire business portfolios are examined, an inverted curvilinear association between diversification relatedness and performance is likely to emerge. This pattern is observed in both acquisitions and joint ventures. However, the association between diversification relatedness and performance in acquisitions is moderated by the level of industry adversity, though factors such as corporate coherence and heterogeneous experience do not moderate the association between diversification relatedness and performance. This study augments the body of knowledge on diversification and adds refinement to the traditional curvilinear finding regarding relatedness. By studying acquisitions and joint ventures independently, the results reveal differences in both slope and inflection points that suggest the relative impact of relatedness may vary depending on the mode of diversification.

Optimal design of Dutch auctions with discrete bid levels.

Description: The theory of auction has become an active research area spanning multiple disciplines such as economics, finance, marketing and management science. But a close examination of it reveals that most of the existing studies deal with ascending (i.e., English) auctions in which it is assumed that the bid increments are continuous. There is a clear lack of research on optimal descending (i.e., Dutch) auction design with discrete bid levels. This dissertation aims to fill this void by considering single-unit, open-bid, first price Dutch auctions in which the bid levels are restricted to a finite set of values, the number of bidders may be certain or uncertain, and a secret reserve price may be present or absent. These types of auctions are most attractive for selling products that are perishable (e.g., flowers) or whose value decreases with time (e.g., air flight seats and concert tickets) (Carare and Rothkopf, 2005). I began by conducting a comprehensive survey of the current literature to identify the key dimensions of an auction model. I then zeroed in on the particular combination of parameters that characterize the Dutch auctions of interest. As a significant departure from the traditional methods employed by applied economists and game theorists, a novel approach is taken by formulating the auctioning problem as a constrained mathematical program and applying standard nonlinear optimization techniques to solve it. In each of the basic Dutch auction model and its two extensions, interesting properties possessed by the optimal bid levels and the auctioneer's maximum expected revenue are uncovered. Numerical examples are provided to illustrate the major propositions where appropriate. The superiority of the optimal strategy recommended in this study over two commonly-used heuristic procedures for setting bid levels is also demonstrated both theoretically and empirically. Finally, economic as well as managerial implications of the findings reported ...

Leader Emergence and Effectiveness in Virtual Workgroups: Dispositional and Social Identity Perspectives

Description: In today's global competitive environment, many organizations utilize virtual workgroups to overcome geographic and organizational boundaries. Research into their dynamics has received the attention of scholars within multiple disciplines, and the potential for an integrative approach to the study of virtual workgroups exists. This dissertation is a first step towards such an approach. The primary aim of this research is to examine antecedent and contextual factors that affect the emergence and effectiveness of leaders in virtual workgroups. To achieve this aim, an integrative model assembled from theory and empirical findings in leadership, management, social identity, and communications research is posited. Hypothesized relationships depicted in the model identify key dispositional and contextual variables linked to leader emergence, member behavior, and leader effectiveness within virtual workgroups. This study employed a nonexperimental research design, in which leader emergence and social identity manifest as naturally occurring phenomena. Data collection occurred via two web-based surveys administered at different points in time. Hypothesized relationships were tested utilizing correlational and hierarchical moderated multiple regression analyses. The findings of this dissertation suggest that traits, such as personality and cognitive ability, are not associated with leader emergence in virtual workgroups. In addition, the results indicate that the exhibition of relationship-oriented leader behaviors enhances group identity. In turn, identification is associated with increases in perceptions of leader effectiveness and decreases in counterproductive behavior exhibited by group members. This dissertation exposes an important limitation to the application of trait leadership theory. It also demonstrates the importance of relationship-oriented behavior and social identity in virtual contexts. Further, it advances an integrative theoretical model for the study of virtual workgroup phenomena. These contributions should assist and inform other researchers, as well as practitioners, interested in leadership and group member behavior in virtual workgroups.

Authentic Transformational Leadership and Implicit Leadership Theories.

Description: Transformational leadership describes a leader who motivates followers to performance beyond expectations, but it has often been attacked for its potential to be abused. A newer form of leadership has been proposed, that of authentic leadership. Authentic leadership is an over-arching concept that proposes to include transformational leadership and all positive forms of leadership. At the heart of authentic leadership is the concept of ethicality. The concept of authenticity may contribute to the transformational leadership paradigm, producing an ideal form of leadership. Authentic leadership may not be an over-arching form of leadership, but one suited particularly to transformational leadership. I propose that authentic transformational leadership resides in leaders' and followers' implicit leadership theories. This experiment addresses authentic transformational leadership and the role of implicit leadership theories in directing leader behavior. A model is developed that outlines the relationship between authentic transformational leadership and implicit leadership theories, including the separate implicit theories of leader and follower, leader-member exchange (LMX), and leader effectiveness. Hypotheses concerning these relationships are developed. The study is experimental, using WebCT as a delivery tool. Scenario-based surveys were developed to collect data, using both known measures and measures developed specifically for this experiment. Two pilot studies were conducted to test the soundness of the delivery tool and the validity of the constructed scenarios and measures, which largely supported the hypotheses. In the main study, all hypotheses were supported with the exception of one. The results of the unsupported hypothesis, however, suggest authentic transformational leadership may be an ideal form of leadership. There are several contributions to the literature made by this study. The first contribution is the development of authentic transformational leadership as an ideal form of leadership. Second, the development of both follower and leader implicit leadership theories and their relationship to authentic transformational leadership is studied ...

An empirical investigation of manufacturing flexibility and organizational performance as moderated by strategic integration and organizational infrastructure.

Description: The purpose of this study is empirically investigating four research questions related to manufacturing flexibility. 1) What are the components of manufacturing flexibility? 2) Is there a relationship between manufacturing flexibility and organizational performance? 3) Do integrated strategies strengthen the relationship between manufacturing flexibility and organizational performance? 4) Are there organizational characteristics that strengthen the relationship between manufacturing flexibility and organizational performance? This study used a cross-sectional survey design to collect data from manufacturing organizations in multiple industries. Organizational performance was quantified using common manufacturing measures. Strategic integration and organizational infrastructure were also measured. Data were collected using a self-administered questionnaire. Factor analysis, correlation analysis, and regression were used to analyze the data. The results indicate the variables and expected relationships exist as hypothesized. This study contributes to the manufacturing flexibility body of knowledge by identifying relationships between the manufacturing flexibility component, performance, strategic integration, and organizational infrastructure. The instrument development in this study is of particular value as there are few rigorously developed and validated instruments to measure the manufacturing flexibility components and performance. Understanding these relationships will help practitioners make better decisions in manufacturing organizations as well as enable application of the concepts in this study to other contexts such as service organizations.

The Impact of Social Capital and Dynamic Capabilities on New Product Development: An Investigation of the Entertainment Software Industry

Description: Businesses today face intense international competition, a heightened pace of development and shortened product life cycles. As a result, many researchers recommend firms collaborate and partner with other firms to succeed. With over a decade of research examining alliances and inter-firm collaboration, we know a great deal about the benefits and outcomes firms realize through collaboration. An important gap exists, however, in our understanding of the effect of partnering firms on collaborative outputs. This study attempts to address this gap by examining the success of collaborative new product development outputs. The study was a quasi-experimental study using archival, time-series data. Hypotheses were tested at the project level, defined as the product output from the collaborative development effort. Predictors were developed at both the firm and dyadic levels. Several findings emerged from this research. The primary finding is that roles of alliance partners impact which capability and capital benefits accrue. Firms functioning as a publisher benefit from increases in relevant experience. Firms functioning as a developer benefit from working in areas in which they have experience, but largely to the extent that the developer also generalizes their capabilities. One implication emerging from the capability findings suggests a need for configurational capability research. From a social capital conception, developers with high network centrality have a negative impact on the perceived quality of the final software product. Developers also benefit from embeddedness, products developed by developers in constrained networks outperformed products developed by developers in brokered networks.

Post-Implementation Evaluation of Enterprise Resource Planning (ERP) Systems

Description: The purposes of this dissertation were to define enterprise resource planning (ERP) systems, assess the varying performance benefits flowing from different ERP system implementation statuses, and investigate the impact of critical success factors (CSFs) on the ERP system deployment process. A conceptual model was developed and a survey instrument constructed to gather data for testing the hypothesized model relationships. Data were collected through a cross-sectional field study of Indian production firms considered pioneers in understanding and implementing ERP systems. The sample data were drawn from a target population of 900 firms belonging to the Confederation of Indian Industry (CII). The production firms in the CII member directory represent a well-balanced mix of firms of different sizes, production processes, and industries. The conceptual model was tested using factor analysis, multiple linear regression analysis and univariate Anova. The results indicate that the contributions of different ERP system modules vary with different measures of changes in performance and that a holistic ERP system contributes to performance changes. The results further indicate that the contributions of CSFs vary with different measures of changes in performance and that CSFs and the holistic ERP system influences the success achieved from deployments. Also, firms that emphasize CSFs throughout the ERP implementation process achieve greater performance benefits as compared to those that focus on CSFs during the initial ERP system deployment. Overall, the results of the study support the relationships hypothesized in the conceptual model.

Interorganizational Relationships: The Effects of Organizational Efficacy on Member Firm Performance

Description: Relationships between the collective actors within interorganizational relationships are a growing area of research in management. Interorganizational networks continue to be a popular mechanism used by organizations to achieve greater performance. Organizations develop competencies to work with other organizations, but the confidence of these organizations to use these strengths for a competitive advantage has yet to be empirically examined. The purpose of this study is to examine organizational efficacy, how competencies may related to that efficacy, and the relationship of efficacy with performance. The goal of this study is to observe the relationship among trust, dependence, information quality, continuous quality improvement, and supplier flexibility with organizational efficacy. In addition, the relationship between organizational efficacy and performance is also observed. There are two primary research questions driving this study. First, what is the relationship between trust, dependence, information quality, continuous quality improvement, supplier flexibility and organizational efficacy? Second, what is the relationship between organizational efficacy and performance? The theories supporting the hypotheses generated from these questions include theories such as social cognitive theory, quality improvement, and path-goal theory. Data collected from the suppliers of a large university support the hypotheses. Regression analysis and structure coefficients were used to analyze the data. Results indicate that both research question one and research question two are supported. In addition, the theoretical model as a whole, which indicates a mediating relationship, was examined and discussed. This study contributes to both academic and practice by examining efficacy in an interorganizational setting. In addition, as organizations better understand the relationship between competencies and confidence, they will better know how to collectively work to achieve greater results with more attention being placed on monitoring the relationship in order to experience more desired outcomes. Limitations of the current study and opportunities for future research are also discussed.
