By employing the theoretical template provided by agency theory, this article contributes a detailed clinical analysis of a large multinational Canada-headquartered telecommunications company, Nortel. Our analysis reveals a twenty-first century norm of usual suspects: a CEO whose compensation is well above those of his peers, a dysfunctional board of directors, acts of income smoothing to preserve the confidence of volatile investors, and revelations of financial irregularities followed by a downfall. In many ways, the spectacular rise and – sudden – fall of Nortel illustrates excesses of actors within, and contradictions of the system of corporate governance implied by the agency model. Furthermore, this case illustrates limitations of the agency framework in complex situations with short-term oriented investors.  相似文献

We assume that early Neolithic cultivators had an optimizing behavior aiming yield maximization and labor efficiency. Then we conduct a hypothetical optimization exercise by examining which consequences such behavior would have if applied to the cultivation of Near-Eastern wild cereals, especially on their rate of domestication measured by the frequency of non-shattering seeds. Two stages of the cultivation process are analyzed, the harvest and the processing. The harvest stage requires two strategies, one about the state of ripeness at the harvest and the other about the harvesting method. We demonstrate that under an optimizing behavior most mature seeds are harvested—by combining two technologies, ground collection and sickling—and thus this stage leads to no selective pressure. On the contrary, the processing stage, from threshing to storage, leads to positive selection when the products of the two harvests are processed separately, a strategy resulting from labor efficiency and risk minimization. Therefore, and from a theoretical point of view, an optimizing behavior tends to support a rapid pathway toward plant domestication, even though the latter is an unconscious outcome of human behavior.  相似文献

While Nintendo develops many video games internally, Apple is only marginally involved in the development of iPhone applications. This paper addresses the question: to what extent and how should system firms be involved in the development of complementary products for their “core products”? These core products may include video consoles, electronic book readers, etc. This is a highly relevant question, because the success of core products depends strongly on their complementary products, e.g., video games and electronic books. This study proposes a dynamic model for the degree that system firms should be involved in complementary product development by considering, as contingency factors, the novelty of the core, and the novelty of the complementary products. Both novelties influence the degree to which system firms should be involved in the development of complementary products. In terms of a system firm's involvement, this study makes a distinction between the degree of integration and the degree of ownership. The degree of integration reflects the extent to which the system firm is actively involved in the coordination of the complementary product, e.g., to ensure that the complementary product is optimally aligned with its core product and that the full potential of the core product is achieved. The degree of ownership reflects the extent to which the system firm finances the development of the complementary product and therefore, the degree of formal control authority over the complementary product. This model was tested using data from a survey of 99 development projects for mobile telecommunications applications. The results reveal that integration by the system firm contributes to the performance of complementary products for new core products but has a negative effect if a new complement is developed for a mature core product. In addition, ownership contributes to performance if both the core and complementary products are new. In other circumstances, a clear effect of ownership by the system firm on performance is not found. The implications of our findings are that system firms should be strongly involved in complementary product development when they introduce a new core product, and even more so if the complementary products are new. However, they should decrease their degree of involvement over time as the core product matures and, again, even more so if the complementary product is new. The paper concludes by providing practical implications for system firms in the mobile telecommunications industry and beyond.  相似文献

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

We consider the relationship between a localcommunity and a private operator in charge ofthe water utility. An important feature of themodel is the possibility of water networklosses that are costly to the operator. Wecompute the first-best and asymmetricinformation solutions to the optimal contract,with private information on the operator'stechnology. Based on an econometric estimationof production cost and water demand for a panelof French local communities, we simulate theoptimal contract solutions and show thatasymmetric information has importantconsequences for the regulation of water publicutilities.  相似文献

Summary The exact distribution function of the ratio of two sums of gamma variates is derived in this paper. The result applies to ratios of quadratic forms and to a statistic used for testing the equality of scale parameters in two gamma populations.  相似文献
