In recent years, many industrial firms have been able to use roadmapping as an effective process methodology for projecting future technology and for coordinating technology planning and strategy. Firms potentially realize a number of benefits in deploying technology roadmapping (TRM) processes. Roadmaps provide information identifying which new technologies will meet firms' future product demands, allowing companies to leverage R&D investments through choosing appropriately out of a range of alternative technologies. Moreover, the roadmapping process serves an important communication tool helping to bring about consensus among roadmap developers, as well as between participants brought in during the development process, who may communicate their understanding of shared corporate goals through the roadmap. However, there are few conceptual accounts or case studies have made the argument that roadmapping processes may be used effectively as communication tools. This paper, therefore, seeks to elaborate a theoretical foundation for identifying the factors that must be considered in setting up a roadmap and for analyzing the effect of these factors on technology roadmap credibility as perceived by its users. Based on the survey results of 120 different R&D units, this empirical study found that firms need to explore further how they can enable frequent interactions between the TRM development team and TRM participants. A high level of interaction will improve the credibility of a TRM, with communication channels selected by the organization also positively affecting TRM credibility.  相似文献

Nearly every day we participate in the vast, interconnected global economy. In doing so, we engage in chains of transactions that ultimately result in our benefiting from, or enabling, wrongdoing by others. In some cases this seems to be in itself wrong, but in many cases it seems unproblematic. I develop a concept of ‘ethical distance’ and argue that our responsibility for the wrongdoing of others is a function of our ethical distance from it. Furthermore, I argue that the concept of moral responsibility is vague, but that when we become clearly responsible for wrongdoing by others, we ought to sever our connection to it.  相似文献

This study investigates the effect of stock option‐based compensation on the short‐term and long‐term performance of French companies. To the best of our knowledge, we provide the first empirical evidence describing the market reaction following initiations and renewals of Employee Stock Option (ESO) plans in France. We find that the French market reacts positively to initiations of ESO plans but does not consider their renewal as relevant information. Our results on the long‐term effect of ESO plans suggest that neither the size nor the value of the grants affect the firm's accounting and market performance. Similarly, corporate performance prior to the grant has no explanatory power of the size or value of the grant. This implies that, over our sample period, the relationship between option‐based compensation and corporate performance in France was inexistent, regardless of the direction considered.  相似文献

Uncovered interest parity (UIP) is estimated for short‐term horizons from one month to 12 months using a large number of cross‐sectional bilateral exchange rates. In contrast to conventional time‐series UIP, cross‐sectional UIP is examined with a single‐equation estimation and panel regression model estimation. The exchange rates analyzed here include a broad spectrum of countries: developed, developing, low‐inflation, and high‐inflation countries. Based on the empirical evidence, there does not appear to be a well‐publicized UIP puzzle for cross‐sectional UIP, and the slope estimates remain largely between zero and one throughout the sample periods, with a few exceptions. Evidence of UIP is more clear for low inflation countries than for high inflation countries. As interest rate maturity becomes longer from one month to 12 months, the UIP relationship becomes weaker.  相似文献

Based on a coproduction concept highlighted by service‐dominant logic, this study attempts to understand the antecedents and consequences of user coproduction in information system development projects. As a key contribution, we posit that user coproduction is influenced by social capital between users and developers; we then postulate that user coproduction determines the project outcomes. Paired data collected from both user representatives and developers by using a survey approach was used to test proposed hypotheses. The results showed that user coproduction has a positively significant influence on project outcomes, and social capital between user representatives and developers is also associated with user coproduction.  相似文献

This article analyzes variations in line‐of‐business diversification status and extent among property–liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line‐of‐business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers.  相似文献

This paper examines the effects of moral philosophy and ethnocentrism on quality of life orientation in international marketing. It also provides a cross-cultural comparison of ethical values between Koreans and Americans. International quality-of-life (IQOL) orientation refers to marketers' disposition to make decisions to enhance the well-being of consumers in foreign markets while preserving the well-being of other stakeholders. It is hypothesized that marketers' moral philosophy and ethnocentrism influence the development of marketers' IQOL. Specifically, the higher the IQOL orientation of international managers, the higher their moral idealism, the higher their moral relativism, and the lower their ethnocentrism. Also, it is hypothesized that American managers are likely to score higher on moral relativism but lower on moral idealism compared to their Korean counterparts. Also, Korean managers are expected to be more ethnocentric than American managers. Data were collected from business professionals who enrolled in professional MBA courses both from the U.S. and Korea. The results provided support for the hypothesized relationships. Managerial implications of these relationships are discussed.  相似文献

The study of divided government is one of important fields in public choice theory. American voters split their ballots as if intent on preserving divided party control. The U.S. House of Representatives has consistently been Democratic for much of the twentieth century. As indicated by Sprague, it is theoretically true that a number of significant consequences for partisan control of a legislature are entailed by the unequal distribution of seat safety under conditions of high levels of institutionalization. The problem is how to measure the institutionalization of partisan seat safety in a time‐series. The model proposed by Sprague is somewhat awkward and complicated in measuring it. This paper provides a more plausible model and tests empirical data.  相似文献

Los autores comparan las normativas sobre vacaciones y licencias susceptibles de facilitar el equilibrio entre vida profesional y familiar de Australia, Canadá, República de Corea, Estados Unidos, Europa occidental y Japón utilizando un índice compuesto para clasificarlas. Los Estados Unidos figuran en último lugar: la concesión de vacaciones anuales al trabajador no es obligatoria y las licencias por motivos familiares se limitan a 12 semanas al año. Este bajo nivel de reglamentación podría deberse, según los autores, a una concepción mercantilista del empleo sumada a la creencia de que empleador y trabajadores tienen idéntica capacidad de negociación, visión no compartida por las demás democracias industrializadas.  相似文献
