基于古诺竞争模型的我国航空产业技术提升策略研究——以大飞机为例

在扩展古诺竞争模型的基础上,通过比较不同技术提升策略对我国大飞机厂商收益的影响,考察了发展大飞机产业自主研发与技术引进的选择问题。研究结果表明,在单一机型竞争市场上,若自主研发的成功概率很大,则国内厂商在未来两期的最优技术提升策略是自主创新;在两种机型竞争市场上,若自主研发的成功概率很大,则国内厂商在未来两期的最优技术提升策略是第一期技术引进、第二期自主研发。     

Consumer evaluation of self-service innovation failure: the effect of brand equity and attribution

The purpose of this study is to examine how, when a self-service innovation fails, customers evaluate different levels of brand equity and how the brand equity effect is moderated by consumer attribution and service recovery. Based on two experimental studies, the results indicate that high-equity brands suffer less from the adverse effects of self-service innovation failures when compared with low-equity brands. However, self-service innovation failures are more detrimental to high-equity brands if they are caused by service providers' internal factors as well as low service recovery.     

Social Preferences,Sorting, and Competition*

In this paper, I investigate how an increase in competition for workers influences the impact of social preferences on labor‐market outcomes. By sorting themselves into firms with homogeneous work forces, workers can ensure that they suffer less from social comparisons. Competition promotes choice and thus facilitates sorting. However, competition also boosts rent differences in the labor market, because firms cannot curb internal inequity among its employees without losing workers to competitors. To reduce their exposure to social comparisons, workers might engage in inefficient sorting into unemployment. Consequently, social preferences can have strong effects (i.e., unemployment) in a competitive labor market, whereas they only have a slight impact on labor‐market outcomes in a monopsony.     

The impact of microcredit on self‐employment profits in Vietnam

This study examines the impact of microcredit on household self‐employment profits in Vietnam. For two indicators of credit participation – a dichotomous participation dummy and the accumulated amount of microcredit received per household – the analysis reveals a positive effect on household profits. The analysis also reveals that an instrumental variable method within a fixed‐effects framework can control for the possible endogeneity of credit and thereby identify the true effect of credit.     

Identification management and its bases: Bridging management and marketing perspectives through a focus on affiliation dimensions

There has been growing interest in both management and marketing regarding how individuals become identified with organizations and how organizations attempt to manage these identifications. The authors present a framework built on explicit and implicit points of convergence in research conducted in both these disciplines. In their review of the management and marketing literatures, the authors suggest three fundamental mechanisms, or “bases”, for managing organizational identification: relational, behavioral, and symbolic. Furthermore, the authors argue that how an individual is affiliated with an organization will impact the relative influence of these identification management bases. The authors conclude by suggesting how management and marketing scholars can create a theoretical space for future interdisciplinary work Such a change would involve moving away from “employees” versus “customers” as a prime division between the fields and moving toward a more fine-grained approach that emphasizes the unique characteristics of individual-organizational relationships. M. Teresa Cardador (cardador@uiuc.edu) is a doctoral student in management at the University of Illinois at Urbana-Champaign. Her research explores issues related to workplace attachment and identification, work orientation, and the experience of employees who find work highly meaningful and engaging. Michael G. Pratt (mpratt@uiuc.edu) is a James F. Towey Fellow and an associate professor of management at the University of Illinois at Urbana-Champaign. He earned his Ph.D. at the University of Michigan. His articles have appeared in leading management outlets, includingAdministrative Science Quarterly, theAcademy of Management Journal, theAcademy of Management Review, andResearch in Organizational Behavior. He recently coedited (with Anat Rafaeli) a book titledArtifacts and Organizations: Beyond Mere Symbolism (Lawrence Erlbaum, 2005). His current research examines issues of organizational attachment (e.g., identification and commitment), multiple identities and meaning, and intuition. Dr. Pratt’s work focuses largely on professionals in both traditional and dispersed work contexts.     

Self‐regulation through Goal Setting*

Goals are an important motivator. But little is known about why and how people set them. We address this issue in a model based on two stylized facts. First, goals serve as reference points for performance. Second, present‐biased preferences create self‐control problems. We show the power and limits of self‐regulation through goals. Goals increase an individual's motivation—but only up to a certain point. Furthermore, they are painful self‐disciplining devices. Thus, greater self‐control problems may result in tougher goals; but for a severe present bias goals either lack a motivating force, or are too painful to be accepted.     

Consumer education and the OECD electronic commerce consumer protection guidelines

This paper explores the implications of e‐commerce transactions and the lack of consumer protection regulation on consumer educators and curricula. The discussion is divided into five sections: conceptualizing e‐commerce; the juggernaut of e‐commerce; consumer education defined, especially consumer protection in the electronic market‐place; the Organization for Economic Co‐operation and Development (OECD) 1998 Ottawa conference on electronic commerce; and the implications of this fluid market and policy context on consumer educators. Empowerment of the consumer, the ultimate objective of consumer education, is a total challenge in the global electronic market‐place, but a challenge that must be embraced by staying informed, becoming a consumer advocate, as well as educator, and remaining ever vigilant as curricula are developed for the domestic consumer transacting in an electronic global market.

THE IMPACT OF ACADEMIC PATENTING ON THE RATE,QUALITY AND DIRECTION OF (PUBLIC) RESEARCH OUTPUT*

We examine the influence of faculty patenting on the rate, quality, and content of public research outputs in a panel dataset of 3,862 academic life scientists. Using inverse probability of treatment weights (IPTW) to account for self‐selection into patenting, we find that patenting has a positive effect on the rate of publications and a weak positive effect on the quality of these publications. We also find that patenters may be shifting their research focus to questions of commercial interest. We conclude that the often voiced concern that patenting in academe has a nefarious effect on public research output is misplaced.
