Relatively little has been written about effectively managing the buyer-seller relationship for marketing research services. To provide insights into effectively managing this relationship, a survey of both buyers and sellers of marketing research services was conducted. Major findings were that proper problem definition, a familiarity with research methods by the research buyer, and continuous communication between buyer and seller were critical determinants of a successful consultant relationship. For best results the market research buyer-seller relationship should be treated as a mutually beneficial one, not one of conflict or acrimony.  相似文献

The study of innovation has been approached from many disciplines and from the point of view of different real life problems. As a result, we have a series of clusters of knowledge that are related but seldom integrated. Chris Voss suggests it is time we closed at least one of these gaps. He suggests there should be a field of study should be established that will build a bridge between work on the process of innovation and work on the diffusion of innovation. He presents a starting point for the new field of study.  相似文献

In this article, the third in the trio of software innovation articles, Chris Voss outlines the key factors that determine whether a new software development is likely to be successful. His research draws on an innovation framework that has emerged from previous research. His results are similar to those of the earlier studies and suggest that the software innovation process has many demands that are common to innovation in other product areas.  相似文献

How does a firm decide whether the amount now being spent to generate sales force applicants is too much, not enough, or about right? This question can be answered by using information routinely generated by corporate activities and a relatively straight forward decision theory technique. To illustrate that technique, an analysis was conducted for a hypothetical but by no means atypical firm. The results suggest that many corporations could appreciably increase their overall profitability by spending more on sales force recruitment and selection.  相似文献

The recycling of consumer solid waste presents special problems for reverse marketing channels. Specifically, the accumulation of bulk quantities of homogenous materials from consumer-generated sources that are highly heterogenous in nature represents a major functional problem that must be overcome through the development of appropriate reverse marketing channels. In this article, factors influencing reverse channels development are outlined, and specific marketing implications concerning the three basic channel types that primarily handle consumer solid waste are discussed.  相似文献

The quality of corporate disclosures has drawn increasing levels of criticism from Congress and the SEC. A subject of particularly intense scrutiny and action is the Management’s Discussion and Analysis (MD&A). This narrative, intended to provide an inside perspective on the reported results of the firm, is particularly important when attempting to evaluate the investment prospects of the marginal or poorly performing firm. However, managers may restrict the information content of the disclosure, raising potential concerns about ethical behavior. In this study, we employ a proprietary instrument to measure the quality of MD&A disclosures for a sample of firms entering financial distress. We evaluate the disclosure behavior of these firms in an effort to determine whether changes in the disclosure appear to be motivated primarily by economic or ethical concerns. We find, on average, that firms increase disclosure quality in the year of initial distress. However, sustained increases in disclosure quality are limited to firms that subsequently recover from the distress. The results suggest that observed changes in disclosure are driven primarily by economic considerations, rather than ethical ones, especially in good economic times.  相似文献

This paper empirically investigates the relationship between stadium attendance, hooliganism and counter‐violence policy measures in Italian Serie A. In particular, this paper analyses the impact of counter‐hooliganism policies adopted in 2007 on the quantity of game tickets sold. The counter‐hooliganism measures, grounded on an entry card, namely a ‘fidelity card’, were designed to keep out hooligans from stadiums so favouring the attendance of either occasional spectators or uncommitted fans. According to our econometric investigation the expected substitution between committed fans and uncommitted fans did not take shape. In sum, the ‘fidelity card’ did not turn to be successful if evaluated on the average attendance perspective.  相似文献
