This paper investigates the antecedents and consequences of two product advantage components: product meaningfulness and product superiority. Product meaningfulness concerns the benefits that users receive from buying and using a new product, whereas product superiority concerns the extent to which a new product outperforms competing products. The present paper argues that scholars and managers should make a deliberate distinction between the two components because they are theoretically distinct and also have different antecedents and consequences. Data were collected through an online survey on 141 new products from high‐tech companies located in The Netherlands. The results reveal that new products need to be meaningful as well as superior to competing products to be successful. This finding is consistent with the prevailing aggregate view on product advantage in the literature. However, the results also show that the effects of the two components on new product performance are moderated by market turbulence. Although each component is important in that it forms a necessary precondition for the other to affect new product performance under circumstances of moderate market turbulence, meaningfulness is most important for new product performance in turbulent markets where preferences have not yet taken shape. In contrast, when markets become more stable, the uniqueness of meaningful attributes decreases, and new products that provide advantage by fulfilling their functions in a way that is superior to competing products are more likely to perform well. In addition, the study shows that the firm's customer and competitor knowledge processes independently lead to product meaningfulness and superiority, respectively. The findings also reveal that under conditions of high technological turbulence the customer and competitor knowledge processes complement each other in creating product meaningfulness and superiority. This implies that the level of technological turbulence puts requirements on the breadth of firms' market knowledge processes to create a new product with sufficient advantage to become successful. The paper concludes that neglecting the distinction between product meaningfulness and superiority when assessing a new product's advantage may lead to an incomplete insight on how firms can improve the performance of their new products. 相似文献

Abstract In this paper we consider the Sparre Andersen insurance risk model. Three cases are discussed: the ordinary renewal risk process, stationary renewal risk process, and s-delayed renewal risk process. In the first part of the paper we study the joint distribution of surplus immediately before and at ruin under the renewal insurance risk model. By constructing an exponential martingale, we obtain Lundberg-type upper bounds for the joint distribution. Consequently we obtain bounds for the distribution of the deficit at ruin and ruin probability. In the second part of the paper, we consider the special case of phase-type claims and rederive the closed-form expression for the distribution of the severity of ruin, obtained by Drekic et al. (2003, 2004). Finally, we present some numerical results to illustrate the tightness of the bounds obtained in this paper. 相似文献

Abstract Four pension plan conversions are examined to determine the impact on retirement benefits of workers. The study was based on interviews with top management, employee surveys, and actuarial analysis of retirement benefits under the old and new pension plans. In general, workers who leave the firm prior to the age of early retirement can expect increased benefits under the new defined contribution and cash balance plans, whereas older, more senior workers can expect to accrue smaller benefits after the plan conversions. Recognizing these potential adverse effects, the employers in our studies provided various types of transition benefits to existing workers or gave employees the choice of remaining in the old defined benefit plan. Employee surveys reveal that younger workers are more supportive of the new pension plans than are older workers. These case studies also indicate that communication by managements with their employees is very important to the successful implementation of plan conversions. 相似文献

In the role of financial analyst for a venture capital firm, you are assigned the responsibility of evaluating two online retailers who have applied for financing to build a distribution center in western Canada. Based on your developing knowledge of Canadian accounting standards for private enterprises (ASPE), you evaluate the financial reporting policies and financial results of the two companies to identify the company that is best suited for your firm's support. Through this case, you will refine your understanding of ASPE and you will exercise your reasoning and analytical skills. 相似文献

Post-normal science is an attempt to increase the problem-solving capacity of scientific work in a context of ‘soft' scientific inputs and ‘hard' policy decisions. The discourse on rhetoric in science can contribute to a better understanding of the problems and potentials of such an effort. The inclusion of ‘extended peer communities' is a case in point of the usefulness of rhetoric for an enterprise that wants to go beyond the normal science of puzzle-solving. The critical potential of rhetoric should be utilized. The distinction between internal and external rhetoric highlights the problematic relationship between scientific and political work, for example in the field of environmental issues. 相似文献

We characterize rationality of certain choice functions C by C(A) ∩ C(B) ? C(A ∪ B) ? C(A) ∪ C(B). We also characterize choice functions coming from preference relations which are partial orders and some other types of relations. Furthermore, we also characterize the admissible set of a binary relation by the fact it is invariant under certain changes in the relation. 相似文献

New rules issued by the U.S. Department of Agriculture requiring provision of nutrition information on raw meat and poultry products may encourage consumers to make healthier food choices. Reduced intake of fat and cholesterol may prevent future cases of stroke, heart disease, and cancer. The benefits of these rules are estimated to be $62 to $125 million annually. 相似文献
