Rudy Moenaert, William Souder, Arnoud De Meyer, and Dirk Deschoolmeester report the results of their study of forty technologically innovative Belgian companies to examine the interaction between marketing and R&D. They studied one commercially successful and one commercially unsuccessful technological product innovation project in each participating company and collected data from one marketing and one R&D respondent per project. Communication flows between marketing and R&D are increased under conditions involving formalization of projects, decentralization, positive interfunctional climate, and role flexibility.  相似文献

As part of the reforms of their systems for financing and delivering health care, many transition economies, particularly in central and eastern Europe, have adopted national insurance funds that are institutionally separate from ministries of health. Most of these countries have also grappled with the problem of restructuring the delivery system, especially the need to reduce hospital capacity. Although improving the performance of medical care providers through a shift from passive budgeting to explicitly incentive mechanisms is important, why this change in financial relations between the government and providers could not be implemented simply by reforming the role of health ministries is not obvious. This paper presents an explicit rationale for the separation of powers between the regulator (the ministry of health) and the financing body (the insurance fund), based on the inability of a single agency to commit to closing hospitals.

This study examines effects of four combinations of accounting bases and service levels — GAAP and income tax bases, and audit and review service levels — on loan officers' decisions, both separately and in interaction. It examines effects on loan decisions and perceptions of interest rates, default risk, confidence, and usefulness. The interaction of accounting basis and service level significantly affects perceived confidence but does not affect other decisions. Accounting basis and service level separately affect interest rates, default risk, and report usefulness, but do not affect the loan decision.  相似文献

This article introduces and explores the concept of brand name imprinting. Brand name imprinting is the process of creating and strengthening the brand name node in the brand memory network through brand name exposure. Brand name imprinting at a time prior to the presentation of specific brand information is posited to improve the retention of that information by strengthening the association between the brand name and brand information. The effect is proposed to be automatic and independent of other known means to strengthen memory associations (e.g., level of attention, cognitive elaboration, stimuli vividness, and stimuli distinctiveness). This research also proposes that brand names with neutral meaning better facilitate the imprinting effect, because they do not carry perceptual baggage that can interfere with the creation of new brand name–information associations. An experiment involving brand name imprinting and the learning of brand information supports these assertions. Implications for communication strategy and brand name selection are discussed. © 2003 Wiley Periodicals, Inc.  相似文献

The question of whether optimal provision of these services comes mainly from established relationships between banks and client firms or can result from arms'‐length market transactions has been the topic of considerable recent debate. This discussion has paralleled the debate in the commercial banking literature on the “specialness” of banks and whether lending can and should be relational or purely transactional. Whether the provision of investment bank services is relationship‐based or transactional is especially relevant now thanks to recent trends that have blurred the distinction between commercial and investment banks, and changed the competitive landscape for investment bank services. In their study summarized in this article, the authors examine whether investment bank‐client relationships create valuable relationship‐specific capital using stock market evidence from the period surrounding the collapse of Lehman Brothers. Specifically, they studied the effect of the Lehman collapse on companies that used Lehman for (1) underwriting equity offerings, (2) underwriting debt offerings, (3) advice on mergers and acquisitions, (4) analyst research services, and (5) market‐making services. The study addressed two specific questions. First, which investment bank services, if any, are associated with the creation of relationship‐specific capital; and second, what are the value drivers of this relationship capital? The authors report finding that companies that used Lehman as lead underwriter for public equity offerings experienced significantly negative abnormal stock returns in the days surrounding Lehman's bankruptcy announcement. By contrast, they find no significant reaction to the announcement for Lehman's debt underwriting clients or any of the other client categories they examine. While most of these investment bank services have at least the potential to create relationship‐specific capital, the authors' findings suggest that except for equity underwriting, all the other investment bank services appear to be transactional rather than relationship‐based, at least in the average case. Moreover, the authors report significant differences even among different groups of Lehman's equity underwriting clients. An equity underwriting relationship with Lehman appears to have been especially valuable for smaller, younger, and more financially constrained firms—those firms which presumably had a high degree of dependence on Lehman to access the capital market.  相似文献
