When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. 相似文献

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses. 相似文献

While the benefits of being market oriented are largely accepted, a group of scholars and managers remain skeptical. Marketing scholars have sought to counter the criticisms leveled against market orientation (MO) by arguing that it has both responsive and proactive dimensions. However, few studies have empirically examined the complexity of the effects of these dimensions on firm performance. Drawing on theories of resource‐based advantage and organizational search behavior, this article advances understanding by arguing that responsive and proactive market orientations have curvilinear effects on product development performance, that their interaction may be positively related to product development performance, and that their effects on new product program performance are moderated differentially by the organizational implementation conditions and marketing function power. Survey results of 175 U.S. firms indicate support for most of the hypotheses. Specifically, whereas responsive MO has a U‐shaped relationship with new product program performance, proactive MO has an inverted U‐shaped relationship with new product program performance. Contrary to the arguments presented here, the interaction of both orientations is negatively related to new product program performance. This study finds that both orientations are needed; however, new product program performance is enhanced when one is at higher level and the other is at lower level. Finally, responsive MO is only positively related to new product program performance under specific conditions such as when strategic consensus among managers is high. On the other hand, the positive effect of proactive MO on new product program performance is further strengthened when learning orientation and marketing power are high. Overall, this study suggests that the effects of responsive and proactive MO on new product program performance are more complex than previously theoretically argued and empirically examined. 相似文献

The fastest growing segment of the hospitality industry is gaming-related business. This industry has experienced record numbers of companies going public, and their stocks are considered favorable long-term investments. Research in the initial public offering (IPO) area suggests that investors acquiring stock at the initial offering price earn large returns. The purpose of this study was to determine if large returns are being experienced for IPOs in the gaming segment of the hospitality industry, and if these large returns were limited to investors who purchased the stock at the initial offer price. There were 14 gaming-related companies selected for the study. The conclusions supported research reporting that the highest returns from IPO investments are made when the stock is purchased at the initial offer price. This study concludes that returns based on the initial offer price were greater than the casino index and the IPO index. When the investor purchased the stock at the first day's closing price, however, returns compared to the two indices were surpassed only after holding the stock for 8 weeks. 相似文献

"In this paper 1980 [Brazilian] Census microdata are used to evaluate the experiences of males who moved from the Northeast to the Southeast in the post- 'miracle' period. Using regression analysis, migrant earnings are compared to those of persons who remain in the Northeast, to estimate the average earnings gain from relocating. These results are then disaggregated by education, age at migration, period of residence, and particular sending and receiving location, to provide more specific information on which groups benefit most. Wide variation in gains is observed, but substantial improvements in earnings are reported in most cases." 相似文献

Summary The old growth theory of the 1950s led to certain conclusions about the sorts of economic policies that would promote economic growth, and also about their limitations. The new growth theory of the 1980s makes much stronger assumptions and leads to correspondingly stronger conclusions about the scope of growth-promoting policy. This article argues that: (1) empirical work so far has neither confirmed nor denied the strong assumptions underlying the new theory; (2) the theory is worth pursuing because of its intrinsic interest and the possibilities it opens up; (3) whatever the final verdict on the new theory, both theory and evidence support the belief that significant long-run gains, even if not permanent changes in the growth rate, can be achieved by increased investment in the broadest sense, including human capital, technological knowledge, and industrial plant and equipment.Fifth Tinbergen Lecture delivered on October 4, 1991, in Amersfoort for the Royal Netherlands Economic Association 相似文献
