Exports,borders, distance,and plant size

The fact that large manufacturing plants export relatively more than small plants has been at the foundation of much work in the international trade literature. We examine this fact using Census microdata on plant shipments from the Commodity Flow Survey. We show that the fact is not entirely an international trade phenomenon; part of it can be accounted for by the effect of distance, distinct from any border effect. Export destinations tend to be farther than domestic destinations, and large plants tend to ship farther distances even to domestic locations compared with small plants. We develop an extension of the Melitz (2003) model and use it to set up an analysis with model interpretations of ratios between large plant and small plant shipments that can be calculated with the data. We obtain a decomposition of the overall ratio into a term that varies with distance, holding fixed the border, and a term that varies with the border, holding fixed the distance. The distance term accounts for more than half of the overall difference.     

Demographics,Personality Traits,Roles, Motivations,and Attrition Rates of Hospice Volunteers

ABSTRACT

The authors conducted a review of prior research on hospice volunteering. The results show that, in most cases, the hospice volunteer is a white, married, middle-aged, financially comfortable, unemployed, female who has some college education, strong religious beliefs and has experienced the loss of someone close (see Tables 1 and 2). The results also show that hospice volunteers tend to share certain personality traits reflecting compassion, tolerance, empathy and sensitivity among others. Volunteers tend to fulfill four roles: direct patient support, education, clerical assistance, and professional services (Bunn 1985). Motivations for volunteering and for continuing one's work as a volunteer appear to be for both personal and altruistic reasons. Primary reasons for discontinuing volunteer service include burnout, communication problems, unrealistic expectations, and insufficient use of the volunteer staff. Gaps in this area of research are identified and topics for further research are presented.     

Green, Reform, Win-Win

Boao Forum for Asia this year enjoys three highlights,namely＂Green,Reform and Win-Win＂. The old but hot topics attracted accumulated attention from the whole world,and more fresh ideas were ushered in.     

Countertrade: Forms,motives, pitfalls,and negotiation requisites

The impressive growth in countertrade necessitates a careful look at this trade financing mechanism and a new attitude by American policy makers and businessmen toward it. This study looks at the various forms of countertrade, at the motivating forces behind it, at the pitfalls that countertrade could engender, and at some imperatives in the negotiation of countertrade deals. The issues are examined from the perspective of a policy maker and that of a businessman. The two perspective are distinct but overlap sufficiently to merit a joint examination. It is the conclusion of this study that countertrade is here to stay, and that American businessmen better learn to cope with it if they are to maintain and improve their competitiveness in the world markets.     

Emotions, store-environmental cues, store-choice criteria, and marketing outcomes

This study integrates extant research relating to store-related cognitions, customer emotions (arousal and pleasure), satisfaction, and loyalty into one framework. The researchers administer a survey to 274 customers in four coffee shops of a major chain. Using these data, the researchers test the hypotheses and model with structural equation modelling. The findings suggest that (a) store-related cognitions differentially affect emotions and customer outcomes (satisfaction and loyalty) and (b) the two emotions of arousal and pleasure differentially mediate the relationships between store-related cognitions and customer outcomes.     

LINKING STRATEGY,STRUCTURE, PROCESS,AND PERFORMANCE IN INTEGRATED LOGISTICS

The current research was undertaken to present and test a framework of supply chain logistics integration that synthesizes current logistics thought with an established theory of organizational design. The framework portrays performance as an outcome of appropriate alignment between strategy, structure, and processes. The results support the contention that a firm that pursues a relational strategy, develops information and measurement structures to support relational processes, and then uses these tools to implement and execute integrated operations will experience high levels of logistical performance. In addition, the results indicate that superior logistics performance is related to simultaneous integration of internal and external operational processes.     

Risk,Liability, and Monopoly

The paper explores a monopolist's safety and output choices when there are potentially large-scale claims that can lead to firm insolvency. Analysis of a monopolized market yields different conclusions than models of rule choice where perfect competition or simple cost-minimization are assumed. The following are shown to be true when consumers do not internalize expected, uncompensated hazard costs: (1) potentially insolvent firms may make more efficient safety and output choices than fully capitalized firms and (2), for any level of capitalization, compliance with a negligence rule—where liabilities are removed—may in fact result in less output and safety than under strict liability, where hazard costs are at least partially internalized. When consumers fully discount risks, a negligence rule dominates strict liability because it allows for less costly, credible commitments to profit- and welfare-maximizing safety investments. The analysis demonstrates that the optimal legal system—including financial responsibility requirements—is particularly sensitive to market structure and the characteristics of firms’ risk reduction technology     

Islam,entrepreneurship, and embeddedness

This study centers on the premise that entrepreneurship is an embedded process. Although “the entrepreneur” is inherently an “individual,” entrepreneurship can never be fully disembedded from the more general social settings within which any business venture is situated. An Islamic‐based economic discursive framework should be cognizant of the different forms of sociality, spatiality, and community as well as the various norms, codes, and symbols that define society more generally. The work of Karl Polanyi on embeddedness is engaged and juxtaposed with Islam's understanding of the ideal mode of economic discursive practices. Islamic economic models and Polanyi are both critical of the corrosive effects of unbridled capitalism and individualism that ultimately lead to reification and exploitation. The conclusion recommends more small‐N case studies by researchers and entrepreneurial educational materials that emphasize the importance of networks and local embeddedness.     

Sex,gender identity,gender role attitudes,and consumer behavior

This article identifies differences between sex, gender identity, and gender role attitudes. Using measures of these constructs, data were collected in a field study of Christmas shopping behaviors. Alternative measurement and multivariate regression models were estimated. The results showed the models best fit the data when the measures were specified as reflecting unique rather than common gender constructs. The measures also each explained significant incremental variance in different shopping behaviors. © 1994 John Wiley & Sons, Inc.     

Effect of marketing activities,benefits, risks,confusion due to over-choice,price, quality and consumer trust on online tourism purchasing

The paper focuses on website vendors and three fundamental aspects, which influence price quality and trust, the major factors that affect purchasing intentions amongst online consumers. The three fundamental aspects in question are: perceived benefits, risks and confusion due to over-choice. The purpose of the study is to examine the influence of these three aspects on consumers' trust and their online purchasing intentions, and also to evaluate their interrelationship with marketing activities. Using the Theory of Planned Behaviour, the research focuses on holidaymakers (N = 735) who bought at least one component of their vacation using the Internet. The research implements Confirmatory Factor Analysis and uses Structural Equation Modelling. The findings indicate the importance of direct marketing and of the brand names of e-retailers and products. They also pinpoint the significance of online buying convenience and of the provision of sufficient product information. Moreover, they reveal the influence of safety and security issues, of the instilment of trust, and of price and quality in relation to purchasing intentions. The research contributes to a better understanding of online tourism decision-making, identifies website vendor characteristics that are important to online consumers and presents a number of managerial implications.     

Formalization,Role Stress,Organizational Commitment,and Propensity-to-Leave

Abstract

This study of Korean industrial salespeople (N = 140) examines the relationships among organizational formalization, role stress, organizational commitment, and propensity to leave. Although most of the theoretical and empirical research in this area was done in the United States, this study examines whether the same concepts could be applied to a culturally different salesforce. The results of the structural modeling analysis suggest that overall the model of job variables and propensity to leave developed in the U.S. could be applied to a Korean salesforce. However, some culture-related differences do exist in the nature of specific relationships.     

Developmental management: Theories,methods, and applications in entrepreneurship,innovation, and sensemaking

This paper summarizes the best papers of the Global Innovation and Knowledge Academy (GIKA) conference, which took place in July 2013 in Valencia, Spain. The Journal of Business Research has published a special issue entitled “Developmental management: Theories, methods, and applications in entrepreneurship, innovation, and sensemaking”. All of them went through many rounds of double-blind reviews and revisions. Theories, methods, and applications are the three pillars to solve the issues in entrepreneurship, innovation, and sensemaking. Entrepreneurship contributes to the quality and future hopes of a sector, economy or even a country. The role of the entrepreneurs is crucial in creating value. Innovation has become important as the global economy seeks to escape from a period of major recession. In organizations, sensemaking consists of cognitive strategies for interpreting reality. It is interesting to examine how these three issues interacting with each other. And these papers contribute to various perspectives of these interactions in different countries.     

ROBOTS,RIFs, and rights

The increasing use of technological advances in business operations very often leads to the displacement of the employee whose skills become obsolete in light of such advances. There is no doubt that the interests of both company and employee are significantly affected by the implementation of laborsaving devices. Given that those interests are pursued in an environment which is usually, if not essentially, competitive, then there arises the serious question of what rights should be accorded the employee and the company in the event that the employee is likely to be displaced by technological innovation. I argue that, given the constraints of a competitive environment, certain rights might be justified through a very limited application of the highly morally intuitive principles of utility, respect for persons, fairness, and the honoring of contracts.

Rethinking managership,leadership, followership,and partnership

Organizations underperform, or fail, when members avoid partnering with managers—whether through subtle resistance, disagreement, protest, or walkout—to achieve common purpose. Managers should boost partnering not by affecting a pretense of leadership but through a nuanced balance of managerial authority and understanding of members’ points of view. The objective of this article is to sharpen attention on the concept of partnership with organization members and how it relates to some of the important previous literature. We also argue that some of the previous scholarly work contributes to misconceptions related to these concepts. Our work is forward-looking in that it is motivated by the dangerous societal and cultural differences evident in the world, differences that surround management’s decisions and that may induce an overuse of authority to quash disquiet. Using our experiences in both industry and academia, we argue that the crucial link between managers and members is leadership—not leadership thought of as directional and inspirational, but leadership as building a relationship toward common purpose through partnership. “Lead” and “leader” are sorely misused terms, and worse, substituting “leader” for “manager” is just plain wrong. We believe that managers become leaders only when followers agree to follow, not when the managers simply step forward energetically with direction. Managers are cheated by mistaken definitions. Reviewing past perspectives about what makes good leaders and managers, we rethink ways to enhance organizational harmony through a clearer understanding of managership, leadership, followership, and partnership. Only by thinking and acting as partners in common purpose can managers and members form the core of success in organizational endeavors.     

Microaggression,anxiety, trigger warnings,emotional reasoning,mental filtering,and intellectual homogeneity on campus: A study of what students think

College campus life is changing based on pressures to create safe environments for students to learn. Much of this change has been outlined in an article by Lukianoff and Haidt entitled “The Coddling of the American Mind.” The authors of the present article asked 188 students from two universities if microaggressions, trigger warnings, emotional reasoning, and mental filtering are prevalent on campus and whether colleges are promoting these concepts. The results show that the majority of students believe that universities must change the way these concepts are addressed to prevent intellectual homogeneity and to adequately prepare them for their business professions.     

Women, Ethics, and MBAs

We argue that the declining female enrollment in graduate business schools is a manifestation of gender bias in business education. The extant conceptual foundation of business education is one which views business activity in terms of a game with fixed and wholly material objectives. This concept betrays an underlying value system that reflects a male orientation. Business education is not merely amoral, therefore, but is gender biased. We suggest that business educators adopt a broadened behavioral rubric. Virtue-ethics theory provides such a rubric.     

Trust,terrorism, and technology

The development of civilization implies an evolution of complex trust mechanisms which integrate the social system and form bonds which allow individuals to interact, even if they are strangers. Key elements of trust are predictability of consequences and an evaluation of consequences in terms of self-interest or values. Values, ethics, and norms enhance predictability. The terrorist introduces an unpredictable event which has negative consequences, thus destroying trust. However, terrorist-like situations occur in day-to-day activities. Technology itself makes the world more interdependent and less predictable. Furthermore, technological accidents and disasters, which are also unpredictable and negative, may prompt individuals to perceive technology as if it were a terrorist. Louis H.
