This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability. 相似文献

We find that positive excess (strong) analyst coverage is associated with overvaluation and low future returns. This finding is consistent with the view that excessive analyst coverage, driven by investment banking incentives and analyst self-interests, raises investor optimism causing share prices to trade above fundamental value. However, weak analyst coverage causes stocks to trade below fundamental values. This finding indicates that investors tend to believe that these firms are more likely to be plagued by information asymmetries and agency problems. The results remain robust after controlling for the possible endogenous nature of analyst coverage and analysts' self-selection bias. 相似文献

This paper shows that the firm has an incentive to issue multiple classes of debt that are differentiated by seniority to enhance securityholder tax-timing option values. The analysis establishes that there is at least one mix of senior and junior debt that maximizes the tax option gain from having multiple priority classes of debt. An analytic example provides specifications for the optimal amount of leverage and the optimal mix of senior and junior debt. Relative to the case of only one class of debt, a multiple debt priority structure increases the optimal amount of corporate leverage. 相似文献

The purpose of this study is to explore the effectiveness of 3D simulation technology for enhancing spatial visualization
skills in apparel design education and further to suggest an innovative teaching approach using the technology. Apparel design
majors in an introductory patternmaking course, at a large Midwestern University in the United States, participated in this
study. Three different teaching methods (lecture, 3D simulation instruments, and paper patternmaking) were employed in consecutive
instructional phases, within a single day. A short questionnaire devised to assess students’ visualization abilities and overall
evaluation on the three different teaching methods was administered to the students after each of the three phases. Overall,
students’ abilities to visualize 2D patterns onto a human body were improved by all three teaching methods. The 3D simulation
instruments anchored positive effects of training on spatial visualization abilities between lecture and paper patternmaking
practices. The results affirm that 3D simulation technology has positive potential as an efficient instructional tool for
improving students’ visualization skills in apparel design. 相似文献

This study empirically examines the relationship between the role of R&D project leaders and their team performance using data from 87 project teams in 6 R&D organizations in Korea. The results reveal that:
(1) R&D project leaders played five different roles in performing their jobs – strategic planner, team builder, gatekeeper, technical expert, and champion;
(2) All but the champion role of a leader is positively related with project team performance;
(3) However, this relationship between the role of leader and project team performance varies according to the characteristics of R&D project teams and their tasks.
Specifically, it becomes important for a leader to focus less on the team building role as the team gets older. The team building role of a leader, however, is more important for higher performance of relatively certain R&D projects, while for uncertain R&D projects, the strategic planning role appears to be more crucial. Based on these results, this study discusses several managerial and theoretical issues related to the role of a leader in R&D project teams. 相似文献

Astroturf organizations are fake grassroots organizations usually sponsored by large corporations to support any arguments or claims in their favor, or to challenge and deny those against them. They constitute the corporate version of grassroots social movements. Serious ethical and societal concerns underline this astroturfing practice, especially if corporations are successful in influencing public opinion by undertaking a social movement approach. This study is motivated by this particular issue and examines the effectiveness of astroturf organizations in the global warming context, wherein large corporate polluters have an incentive to set up astroturf organizations to undermine the importance of human activities in climate change. We conduct an experiment to determine whether astroturf organizations have an impact on the level of user certainty about the causes of global warming. Results show that people who used astroturf websites became more uncertain about the causes of global warming and humans’ role in the phenomenon than people who used grassroots websites. Astroturf organizations are hence successful in promoting business interests over environmental protection. In addition to the multiple business ethics issues it raises, astroturfing poses a significant threat to the legitimacy of the grassroots movement. 相似文献

In two online experiments this research investigated the process by which consumers respond to online apparel stock outages (or stockouts) and examined the effectiveness of managerial responses in mitigating the adverse impact of stockouts. Results of Experiment 1 demonstrated that negative emotions evoked by stockouts depressed perception of store image, lowered decision satisfaction, and reduced behavioral intent. In addition, the effect of negative emotion on behavioral intent was mediated by perception of store image and decision satisfaction. The results of Experiment 2 showed that financial compensation was most effective in mitigating the negative impact of out‐of‐stock occurrences on consumer responses. © 2011 Wiley Periodicals, Inc. 相似文献

Sales managers often are required to give negative information to their sales personnel. Perhaps the salespeople's territories will be reduced, their compensation or expense program decreased, or their positions realigned or eliminated. Although extensive research has examined delivering negative news to sales personnel, no empirical work has yet explored how that inimical information should be disseminated to sales subordinates. Scholars in organizational psychology argue that providing adverse news to employees using interpersonal sensitivity is advantageous for both the individual and the organization. To date, though, this issue has not been investigated in a selling context. Therefore, this article reports the results of an exploratory study that investigated factors that influence whether sales managers provide negative communication to salespeople in an interpersonally sensitive fashion. © 2011 Wiley Periodicals, Inc. 相似文献

One way consumers cope with an unfair consumption experience is to express how they felt about it. Understandably, these disclosures are often rich with emotion. Does emotional disclosure in this context influence consumers' perceptions of fairness? Drawing hypotheses from the emotional disclosure literature, this research reveals that writing about emotions improves consumer fairness perceptions and satisfaction. However, the benefit of emotional disclosure disappears if the disclosure is solicited by the company perceived to be responsible for the unfairness and they do not offer redress. The findings lead to the recommendation that companies provide and facilitate opportunities for consumers to disclose to third parties the emotions arising from consumption experiences perceived as unfair. Implications for managing customer feedback, complaints, and negative word‐of‐mouth are discussed. © 2011 Wiley Periodicals, Inc. 相似文献

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO. 相似文献
