This paper addresses the issue of R&D programme prioritisation within a manufacturing company in the aerospace industry, in the context of an overall framework for technology management. A review of approaches to R&D project selection leads into a recent case, which describes how the company developed a practical methodology. The benefits of the process and the relevance of the academic contribution are discussed, leading to a practical checklist for in-company development of a prioritisation process. 相似文献

Recent history has seen an increase in the utilization of partial equilibrium based forest sector models to identify potential impacts of various policies or timber market shocks. These models are particularly useful in that they employ economic theory to capture the interaction of supply and demand in a framework where commodity prices are endogenous to the policy or shock simulated. We present recent developments and linkages between models and review applications of these models to forest policy questions over the previous decade. We conclude with a discussion of potential future directions for such research. 相似文献

This article proposes that neuroscience can shape future theory and models in consumer decision making and suggests ways that neuroscience methods can be used in decision-making research. The article argues that neuroscience facilitates better theory development and empirical testing by considering the physiological context and the role of constructs such as hunger, stress, and social influence on consumer choice and preferences. Neuroscience can also provide new explanations for different sources of heterogeneity within and across populations, suggest novel hypotheses with respect to choices and underlying mechanisms that accord with an understanding of biology, and allow for the use of neural data to make better predictions about consumer behavior. The article suggests that despite some challenges associated with incorporating neuroscience into research on consumer decision processes, the use of neuroscience paradigms will produce a deeper understanding of decision making that can lead to the development of more effective decision aids and interventions. 相似文献

Control and governance theories recognize that exchange partners are subject to two general forms of control, the unilateral
authority of one firm and bilateral expectations extending from their social bond. In this way, a supplier both exerts unilateral,
authority-based controls and is subject to socially-based, bilateral controls as it attempts to manage its brand successfully
through reseller channels. Such control is being challenged by suppliers’ growing relative dependence on increasingly dominant
resellers in many industries. Yet the impact of supplier relative dependence on the efficacy of control-based governance in
the supplier’s channel is not well understood. To address this gap, we specify and test a control model moderated by relative
dependence involving the conceptualization and measurement of governance at the level of specific control processes: incenting,
monitoring, and enforcing. Our empirical findings show relative dependence undercuts the effectiveness of certain unilateral
and bilateral control processes while enhancing the effectiveness of others, largely supporting our dual suppositions that
each control process operates through a specialized behavioral mechanism and that these underlying mechanisms are differentially
impacted by relative dependence. We offer implications of these findings for managers and identify our contributions to channel
theory and research. 相似文献

Whereas longevity‐adjusted consumption measures have become increasingly used as indicators of lifetime standards of living, it remained unnoticed that those measures, by relying on period – rather than cohort – life tables, constitute indicators of expected – rather than actual – lifetime standards of living. In order to estimate the actual gap between ex ante and ex post measures of lifetime welfare, this paper computes, for 19th‐century European economies, longevity‐adjusted consumption measures based on period and cohort life tables. It is shown that the gap between ex ante and ex post measures is statistically significant, and that attempts to reduce it are likely to be unsuccessful, because standards of living tend to exhibit, over temporal horizons as long as a human life, structural breaks, which make the ex ante measurement of lifetime welfare highly speculative. 相似文献

Previous work has identified that IPOs underperform a market index, and the purpose of this paper is to examine the robustness of this finding. We re‐examine the evidence on the long‐term returns of IPOs in the UK using a new data set of firms over the period 1985–92, in which we compare abnormal performance based on a number of alternative methods including a calendar‐time approach. We find that, using an event‐time framework, there are substantial negative abnormal returns to an IPO after the first 3 years irrespective of the benchmark used. However, over the 5 years after an IPO, abnormal returns exhibit less dramatic underperformance, and the conclusion on negative abnormal returns depends on the benchmark applied. Further if these returns are measured in calendar time, we find that the (statistical) significance of underperformance is even less marked. 相似文献

We examine a situation where a manufacturer operates in a two‐mode production environment. The first mode could involve overseas vendors and manufacturing facilities. If additional units are later required, the company must use its second mode—more expensive last‐minute domestic vendors and manufacturing sites. We develop a new methodology for analyzing the impact of forecast accuracy on the decision to postpone production. We examine the interaction of forecast accuracy, shortage vs. holding costs, transportation costs and the cost of postponing production in the supply chain of a single product facing uncertain demand. Our model can be used to analyze the cost of important changes, such as increasing forecast accuracy, reducing the cost of backorders, lowering the cost of delaying production, or lowering transportation costs. Our model allows a firm to understand its overall cost structure so that it can accurately evaluate the impact of improved forecast accuracy and lowered costs in the context of postponement. 相似文献

Residential segregation has played a central role in theories of minority entrepreneurship and in the diversification of the
U.S. labor market. Racial diversity in public accommodations, including schools, has been an issue of continuous public policy
debate at least since the U.S. Supreme Court’s Plessy versus Ferguson decision (1896). This study applies theory from the literature on social capital to an examination of the role of racial
segregation in the public schools of blacks during childhood on their adult likelihood to become self-employed and their level
of occupational status. The model results indicate that, after controlling for a number of individual, household and metropolitan-area
factors, lower rates of segregation during public schooling results in higher likelihood of wage-salary employment and self-employment
among a cohort of black Americans that attended public schools during the 1960s. 相似文献
