An effective R&D organization needs information from a complex web of sources, including customers, suppliers, sales and marketing, and company management. Within the R&D organization, information must flow into and among numerous teams. This network of interpersonal communications can go a long way toward determining the success of a company's innovation efforts. In an exploratory study of a Belgian company operating in the telecommunications industry, Rudy K. Moenaert and Filip Caeldries examine the effects of interpersonal communication on market and technological learning in R&D. Trying to improve the flow of information into and within its R&D organization, this company designed its new R&D facility with an eye toward improving both market and technological learning throughout the organization. By locating R&D personnel in closer proximity to one another, management hoped to provide them with improved access to market and technological information, and thus increase their innovativeness. Contrary to expectations, placing R&D professionals in closer proximity to one another did not increase technological learning in this organization. In fact, technological learning actually decreased slightly during the period studied, though the change is not statistically significant. On the other hand, market learning and product innovativeness improved significantly during the period studied. For an R&D professional in this company, members of other R&D teams seem to be more important as sources of market information than as sources of technological information. Surprisingly, the relocation of R&D personnel also did not increase the amount of communication that takes place, either within a project team, between members of different teams, or between R&D professionals and the management steering committee. However, the architectural redesign does appear to have improved the quality of communication. R&D team leaders report that since the relocation, the information flowing into R&D has been more customer focused. This is attributed to the company's ongoing efforts to provide the tools and structures necessary for supporting the objectives of the architectural redesign. For example, implementation of quality function deployment (QFD) has helped innovation team members to focus more clearly on relevant information. The success of the architectural design required approaching this effort as a complex, ongoing process, rather than a quick-fix solution.  相似文献

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

This paper examines occupational performance in Australia across three racial groups in Australia: Indigenous Australians; Asian people, defined as all those whose language spoken at home was either Chinese, Vietnamese or other forms of a South-east or East Asian language; and white people, defined as the residual category. The paper has as its starting point, observed differences in occupational attainment among the three groups in Australia and sets out to account for these observed differences on the basis of both race and non-racial attributes such as, age, education and area of residence.  相似文献

In this paper, we examine the impact of managerial self-interest on the value of multinationality. Since agency theory also suggests that a divergence between the interests of managers and shareholders can be aligned by effective managerial incentive, we also examine the effect of managerial compensation on the value of multinationality. Our results show that for high- Q (Tobin's Q > 1 ) firms, investors do not associate the spending of free cash flow on multinationality with the problem of overinvestments. For high- Q firms, it is also found that the value of multinationality can be enhanced by effective managerial incentives. For low- Q firms (Tobin's Q < 1 ), it is found that the concern of managerial self-interest overwhelms the benefits of internalization, making multinationality a value-decreasing event. For low- Q firms, managerial compensation is also ineffective in promoting value-enhancing foreign direct investments.  相似文献

At some stage in every household's family life cycle, the household is likely to make certain decisions with regard to its housing environment. Although the household's housing decisions essentially comprise the decision to move, and the selection of a new residence, the process from which these decisions are derived is very complex because varying circumstances could produce a multitude of different housing decisions. Due to the sheer complexity of the household's housing decision–making process, researchers have generally focused on individual decision–making stages rather than on the process as a whole. This paper therefore attempts to conceptualize the entire household housing decision–making process using theoretical concepts from the economic perspective, and then tests the conceptual model with empirical evidence drawn from the moving population within the multi–racial society in Singapore.  相似文献

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.  相似文献

A large body of evidence indicates that macroeconomic and financial variables are dynamically interrelated. In an international setup, we analyze the transmission mechanisms of macroeconomic shocks on the stock market of a small open economy in an increasingly integrated world. We use a time-varying vector error correction model (VECM) that allows analysis of asymmetric impacts that depend on the state of the business cycle. A special focus is directed on monetary policy surprises, where we find that foreign shocks exert a strong influence on an integrated stock market, and that the stage of the business cycle heavily affects the signals of the shocks.  相似文献
