Parasitism and Internet auction fraud: An exploration

Most research on Internet auction fraud focuses exclusively on the relationship between the con-artist and victim. However, the con-artist and victim are situated in an ecology comprising the auction house, police, and auction community. This paper employs the ‘parasite’ metaphor as a way of building theory about Internet auction fraud. We begin by describing the parasite metaphor. We then introduce three theories from the parasitism literature and demonstrate the insights these theories can produce. The first theory, the competitive exclusion principle, highlights how separate auction markets evolve their own species or types of fraud. It also warns us that fraud elimination may be neither desirable nor feasible relative to constraining fraud to acceptable levels. The second theory details various parasite infection mechanisms to show that on-line fraud is composed of two processes; the actual deception and escape. Finally, virulence theory provides one way to predict how much harm a particular kind of fraud will cause to an individual victim. Virulence theory is also used to suggest that the auction infrastructure encourages low virulence vis-à-vis other kinds of fraud like Nigerian letter fraud.     

Hunting while working: An expanded model of employed job search

Major theoretical models of job search fail to consider the changing nature of careers, the influence of the internet as a job search tool, and the diverse objectives for employed job search. Consequently, the study of employed job search has been largely confined to turnover research. We add to existing theory by providing a typology of employed search objectives based on modifying employment conditions (separation-seeking, change-seeking, leverage-seeking), contagion (mimetic-seeking) and employability (knowledge-seeking, network-seeking) and offer propositions related to the antecedents and implications for each objective. This classification offers an alternative explanation for previous research findings, provides a framework for future study, and has practical implications for employee retention and recruitment.     

Managerial Collective Cognitions: An Examination of Similarities and Differences of Cultural Orientations

abstract    Using the context of market orientation, we examine how an exemplary business's market orientation culture is reflected in managers' mental models, evaluate how mental models and perceived behaviours differ across hierarchical levels and functions, and compare the cognitive values and beliefs or the cognitive aspects of market orientation culture with behavioural aspects. Results from a rich, multi-method, case study suggest that while managers in the business share core beliefs regarding the customer dimension of market orientation, their beliefs regarding competitors, technology and inter-functional coordination dimensions vary widely across the levels and functions of the business. We found differences in terms of both the integration between the four dimensions of market orientation and the depth of knowledge within the dimensions. Our findings reveal that customer rather than competitor beliefs are the most important commonly shared beliefs in successful companies, leading us to encourage cognitive researchers to move beyond competitor analysis when examining managerial cognition. Another implication for future research is that a strong market orientation implies common core beliefs regarding customer dimensions but does not imply that all beliefs will be or should be shared. From the methodological standpoint, we find that cognitive mapping techniques provide rich insights into a business's market orientation culture that are not gained from behavioural methods alone.     

Collective Intentions and Collective Intentionality

A BSTRACT . John Searle believes that collective intentions are crucial to his philosophy, but he is yet to present a coherent account of these entities. No account whatsoever of collective intentions is presented in the book where Searle needs them the most ( The Construction of Social Reality ), or, for that matter, in any other of Searle's major books. The only account, and a defective one at that (so I argue), is found in a short, somewhat obscure article entitled "Collective Intentions and Actions," but in fact what Searle presents there is, at best, an account of collective actions , not of collective intentions. In light of Searle own ground-breaking work in the philosophy of mind, and in particular in light of his far-reaching analyses showing how intentions differ from related mental states, I argue that collective intentions are not consistent with Searle's philosophy of mind.     

Price rigidity: An exploration of the demand side

This paper presents an exploration of the demand-side effects of unanticipated price changes. Consumers faced with these changes may have to reoptimize their income allocation. Reoptimization is costly, and reoptimization costs result in kinked demand curves. The existence of such kinked demands provides an additional explanation of the observed nominal price rigidity. In addition, examination of unexpected nominal price changes during inflationary periods provides some justification as to why nominal price adjustments are large, infrequent and almost never downward.     

Supervisor-subordinate guanxi: A meta-analytic review and future research agenda

The present research focuses on supervisor-subordinate guanxi (SSG) – a non-work or personal tie that reflects the relationship between a subordinate and their supervisor. Although SSG has received considerable attention, results are mixed. Further, how the Eastern conceptualization of SSG differs from the Western conceptualization of leader-member exchange (LMX) remains nebulous. We meta-analyzed 71 samples that contain 238 effect sizes. We found that: (1) SSG has a strong overlap with LMX (ρ̅̂ = 0.56); (2) SSG has small magnitude relations with its correlates (age, gender, education, and tenure); (3) SSG demonstrates smaller relative weights than LMX in predicting outcome variables (task performance, organizational citizenship behavior, job satisfaction, organizational commitment, turnover intention, subordinates' perceived distributive justice, subordinates' perceived procedural justice, and trust in supervisor); and (4) SSG contributes statistically significant, yet very small (ranging from 0.00 to 0.04), incremental validity above and beyond LMX in predicting all of the aforementioned outcome variables except for subordinates' perceived distributive justice. We conclude with a discussion of future directions for research on SSG.     

Collective Action Cascades: An Informational Rationale for the Power in Numbers

Self-interested individuals pursue their goals rationally taking into account the constraints imposed by their environment and best-responding to the strategic behavior of other individuals: when applied to collective action, economic theory predicts undersupply.
Meanwhile, the behavior of masses of people is described as excitable, emotional, irrational, suggestible, hypnotic, disorderly, and unpredictable: in practice, it seems, collective action is oversupplied, and erratically so. The contagious and volatile dynamics of collective action appear to defy rationalization.
I conceptualize a social movement as a dynamic informational cascade. Turbulencies emerge endogenously from rational individual behavior. Disorderly mass behavior is a by-product of a powerful decentralized mechanism of information aggregation.

Feedback frequency and appraisal reactions: a meta-analytic test of moderators

Abstract

Performance appraisals provide employees with feedback that helps them improve subsequent performance, with acceptance of feedback as a key precondition to improve performance. In this study, we use the due process model of performance feedback to better understand predictors of favorable employee reactions to performance appraisal. The due process model views knowledge of performance standards and frequent feedback as aspects of adequate notice in performance appraisal, and as key predictors of favorable appraisal reactions. Empirical findings to date, however, have been inconsistent on this issue. Feedback frequency has not been consistently related to appraisal reactions in primary studies, suggesting the potential for moderator effects. We therefore meta-analyzed the relationships between knowledge of performance standards and feedback frequency with appraisal reactions through the due process lens with performance rating favorability and knowledge of performance standards as moderators. Our findings suggest prior inconsistent results could be partly explained by the moderating effects of performance rating favorability and knowledge of performance standards on the relationship between feedback frequency and appraisal reactions. We discuss the implications of our results for theory, research and practice.     

Relationship between just-in-time manufacturing practices and performance: A meta-analytic investigation

Just-in-time (JIT) manufacturing is among the most commonly researched topics in the area of operations management. This study examines the relationship between JIT manufacturing practices and performance outcomes by means of meta-analysis of correlations approach. Based on an in-depth analysis of literature spanning from 1992 to 2008, the results of this meta-analytic investigation support a positive relationship between JIT manufacturing practices and aggregate performance. However, the findings suggest that not all individual JIT practices are associated with all types of performance outcomes. This study highlights the JIT practices that have the greatest impact on individual performance outcomes and emphasizes the role of moderating factors in the relationship between JIT practices and performance. Theoretical and managerial implications are discussed and directions for future theory building in JIT are presented.     

CEO overconfidence and agency cost of debt: An empirical analysis of CEO turnover events

We develop a model and characterize the differences between the investment policies of a rational CEO and an overconfident CEO. In the presence of risky outstanding debt, we show that an overconfident CEO has the incentive to overinvest more than that of a rational CEO. However, this incentive is mitigated by the discipline imposed by outside investors when an overconfident CEO seeks external financing. In contrast, when the firm has sufficient internal funds to meet its investment needs and outstanding debt is relatively safer, the overconfident CEO has no necessity to seek external funds and the overinvestment incentive persists. We examine bondholders’ and stockholders’ reaction around CEO turnover announcements and find evidence consistent with the over investment hypothesis.     

Monetary policy announcements and stock reactions: An international comparison

This article investigates the impact of domestic monetary policy rate announcements on the stock markets of New Zealand, Australia, the United Kingdom and the euro area, using event-study methods to identify stock price reactions to the unanticipated/surprise component of announcements. As Australia and New Zealand did not reach the zero bound we investigate whether there is an impact from the global financial crisis on stock market reactions that can be distinguished from the asymmetric reactions to surprises that characterise the business cycle. We find that the euro area and the UK both show a financial crisis effect but behaviour in New Zealand and Australia does not change. We conduct robustness checks and explore confounding factors, especially the impact of ‘guidance’ from central banks that prepares markets for policy rate changes.

How environmental innovation influences firm performance: A meta-analytic review

Coupled with the increasing concern toward sustainability and sustainable development issues, environmental innovation practices have been of burgeoning interest among both scholars and practitioners. Building on this, the main purpose of this study is to quantitatively aggregate the extant empirical research on eco-innovation and firm performance and to assess the role of moderating factors in this theoretical relationship by pursuing a meta-analytic approach. To serve this objective, 196 effects based upon 70 studies including more than 25,000 firms (N = 25,412) were meta-analytically examined. Quantitative evidence drawn from the meta-analysis indicates that organizational eco-innovation exerts the strongest influence on firm performance. Moreover, the meta-analytic findings suggest that significant variations in the correlation between eco-innovation and firm performance exist across different performance types, and the magnitude of the eco-innovation–firm performance association is stronger in developing compared with developed countries. This meta-analytic review is expected to considerably contribute to the pertinent literature by means of improving the understanding of the relevance of eco-innovation typology to firm performance.     

An expanded investigation into the relationship of corporate social responsibility and financial performance

While many studies have examined the relationship of the two constructs of financial performance and CSR, little consensus has emerged. This study investigates the relationship through a set of comprehensive and long-term financial measures, which include both accounting and market returns. Also, an established CSR database generated through a validated CSR research instrument is used in a new, more thorough manner. While the regression analyses reveal no relationship to exist between the constructs, a number of methodological factors are proposed to play a role in contributing to such findings.     

Control and commitment HR practices,job satisfaction and turnover intentions: a comparison between local and multinational firms in China

There is a growing body of literature and debate around control versus commitment human resource management (HRM) systems and their impacts on employees. However, the impacts of these constructs have not been widely examined in more emerging economies. Taking a specific sample of educated professionals working for multinational and local firms in China, this study investigated employee perceptions of control and commitment HR practices, job satisfaction and turnover intentions. A total of 311 respondents completed a structured survey questionnaire. Results revealed that those working for multinational firms reported more positive perceptions of their employers' control and commitment HR practices. In multinational firms, the use of commitment HR practices predicted lower intentions to leave. However, in domestic firms a lack of control HR practices predicted higher turnover intentions. Theoretically, the study adds to discussions about the nature and roles of these constructs, their impacts on HR outcomes and how institutional mechanisms might shape the degree of HRM homogeneity and hybridity across organizations in China. Practically, the study provides guidance to international and local firms on how to improve their HRM effectiveness to achieve a higher retention of their most talented professionals.     

Revisiting the interplay between contractual and relational governance: A qualitative and meta-analytic investigation

Although extant literature has shown that formal contracts and relational governance play a key role in interorganizational relationships, the nature of their interplay still remains equivocal. To better understand the relationships between contractual and relational governance, we conducted a qualitative review and meta-analysis of the existing literature. Meta-analytic results from 33,051 interorganizational relationships across 149 empirical studies have indicated that contractual governance is positively related to both sides of relational governance—trust and relational norms. Our results have also indicated that contracts, trust, and relational norms jointly improve satisfaction and relationship performance and jointly reduce opportunism. These findings provide strong evidence for the complementarity arguments of the contractual–relational governance relationships and their joint impacts on performance. We also found that the mutual relationships between contractual and relational governance are moderated by the institutional environments, the interorganizational relationship type and length, and the construct measurement of contracts. Overall, this study provides new insights on when contractual and relational governance complement or substitute each other. We discuss the implications of our study for theory and practice and propose a research agenda for future research on governance in interorganizational relationships.     

PDF versus LP: An empirical aggregate planning comparison

Production Decision Framework (PDF) is a recently introduced heuristic method for solving the aggregate planning problem. The algorithm was developed and tested over a wide range of deterministic demand patterns and cost parameters. The decision by Wayn-Tex Inc., to adopt the methodology provided a real world opportunity to evaluate the performance of PDF under uncertainty over a one year's operating period.This paper concentrated on a study of (1) the effectiveness of the model in selecting a suitable rolling planning horizon, and (2) the performance of PDF as compared to a linear program solution using the same length horizon. The monthly sales forecast used in the study, developed by the sales department, took into consideration trend, seasonality, and known market conditions. The results were gratifying. Management has indicated their desire to continue using PDF as a guide in the production planning process through the use of the computerized program available.
