If you could tell which product characteristics consumers would prefer, product development could be targeted sharply and positioning the product competitively could be done with more confidence. This article describes one approach by which a relatively large set of test products is evaluated by consumers in order to identify the most acceptable combination of product attributes. Identification of this combination provides the product developer with guidelines as to which test product should be selected for subsequent introduction. The focus is on the discovery of discernible attributes of a product in a fragmented category to support the advertising claim. 相似文献

Despite moves toward electronic funds transfer systems, the financial community must continue to cope with the labor-intensive paper processing requirements associated with a payments mechanism still heavily reliant upon checks. An attempt to eliminate the labor intensity is the recent development of optical scanning capture equipment which “reads” printed or handwritten documents. Mathematical programming models are used to compare the manual and the automated processing systems on a cost basis and to identify the kind of environment suitable for automation. 相似文献

For purposes ranging from practical commercial policy matters to the testing of theoretical trade models, economists have utilized aggregate data relating to tariffs and non-tariff barriers (NTBs) across countries. However, the statistics employed in these analyses are generally derived using aggregation procedures which are based on weights relating to trade that occurs under restrictions. While it is recognized that this approach incorporates a bias in the resulting averages, due to the fact that the products facing the highest tariffs or NTBs enter the calculation with relatively low (actual) trade weights, little information is available for quantifying the magnitude of this bias. This study provides such empirical evidence and also proposes indices that overcome some shortcomings of the traditional measures. 相似文献

During the period when capital punishment was regularly used in England and Wales, the risk of self-execution from suicide, when suspected of murder, greatly dominated the risk of death at the hands of the state. Over the period 1900–1949, even with four years' data missing, there were 1,540 suicides by those suspected of murder. Using econometric analysis it is found that there is no significant relationship between self-execution and state execution. 相似文献

Isolated pockets of innovation can be found in projects—such as the novel solution used to redesign the Velodrome roof during the London 2012 Olympics—but there have been few, if any, systematic efforts to manage innovation in a megaproject. This paper presents the initial findings of an ongoing three‐year (2012–2014) action research project between Crossrail and researchers at Imperial College London and University College London. Action research is well suited to a setting where an intervention is required to diagnose and solve an organizational problem and produce scientific findings (Miles & Huberman, 1994; Van de Ven, 2007). Undertaken in collaboration with practitioners, the aim of action research is to transform the research setting through a process of critical inquiry and action. Our engagement with Crossrail aimed to formulate and implement an innovation strategy to improve the performance and outcomes of the project. We identified four stages—or windows of opportunity—to intervene to generate, discover, and implement innovation in a megaproject: (1) the bridging window during the front‐end when ideas, learning, and practices from other projects and industries can be used to create an innovative project process, organization, and governance structure; (2) the engaging window, when tendering and contractual processes can be used by the client to encourage contractors and suppliers to develop novel ideas and innovative solutions; (3) the leveraging window, when all the parties involved—clients, delivery partners, and suppliers—are mobilized to develop novel ideas, new technologies, and organizational practices to improve performance; and (4) the exchanging window at the back‐end, when ideas and resources for innovation can be (re)combined with those of other projects in the wider innovation ecosystem to improve performance. The first two stages had largely occurred when we became involved in the Crossrail project in 2012. Our intervention addressed the final two stages, when we assisted in the development and implementation of an innovation strategy. Core to this strategy was a coordinated mobilization of the innovative capabilities across the project supply chain. Though, to be successful, this approach had to be open enough to span organizational boundaries beyond the supply chain, reaching into the broader ecosystem. The four windows provide a valuable new heuristic for organizing innovation in megaprojects, pointing to areas where project managers can craft targeted innovation interventions and compare their efforts with those of others. 相似文献

Aim: This study presents the cost-utility analysis that was developed to inform the NICE health technology assessment of osimertinib vs platinum-based doublet chemotherapy (PDC) in patients with EGFR-T790M mutation-positive non-small cell lung cancer (NSCLC) who have progressed on epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy.Methods and materials: A partitioned survival model with three health states (progression-free, progressed disease, and death) from a UK payer perspective and over lifetime (15 years) was developed. Direct costs included disease management, treatment-related (acquisition, administration, monitoring, adverse events), and T790M testing costs. Efficacy and safety data were taken from clinical trials AURA extension and AURA2 for osimertinib and IMPRESS for PDC. An adjusted indirect treatment comparison was applied to reduce the potential bias in the non-randomized comparison. Parametric functions were utilized to extrapolate survival beyond the observed period. Health state utility values were calculated from EQ-5D data collected in the trials and valued using UK tariffs. Resource use and costs were based on published sources.Results: Osimertinib was associated with a gain of 1.541 quality-adjusted life-years (QALYs) at an incremental cost of £64,283 vs PDC (incremental cost-effectiveness ratio [ICER]: £41,705/QALY gained). Scenario analyses showed that none of the plausible scenarios produced an ICER above £44,000 per QALY gained, and probabilistic sensitivity analyses demonstrated a 63.4% probability that osimertinib will be cost-effective at a willingness-to-pay threshold of £50,000.Limitations: The analysis is subject to some level of uncertainty inherent to phase 2 single-arm data and the immaturity of the currently available survival data for osimertinib.Conclusions: Osimertinib may be considered a cost-effective treatment option compared with PDC in the second-line setting in patients with EGFR-T790M mutation-positive NSCLC from a UK payer perspective. Further data from the ongoing AURA clinical trial program will reduce the inherent uncertainty in the analysis. 相似文献

Resource‐based theory (RBT) has emerged as a key perspective guiding inquiry into the determinants of organizational performance. Since the early 1990s, numerous studies have examined RBT's assertion that the extent to which organizations possess strategic resources is positively related to performance. Although many studies appear to support this assertion, there is no consensus regarding how strongly strategic resources relate to performance. To help resolve this issue, we meta‐analyze 125 studies of RBT that collectively encompass over 29,000 organizations. Our conservative estimate is that the effect size of the strategic resources–performance relationship is r?c = 0.22. Moderator tests suggest that the resources‐performance link is stronger (1) when resources meet the criteria laid out in RBT and (2) for those performance measures that are not affected by potential value appropriation. When resources meet RBT's criteria and when performance measures are not affected by potential appropriation, the strength of the relationship grows to r?c = 0.29. This suggests that the identification, development, and distribution of value from strategic resources should be a primary consideration for scholars, managers, and shareholders.

This study estimates the multiplier effect of the exhibition industry. In order to calculate the exhibition industry's total expenditure, consideration is made of three major sources of expenditure including hosts, exhibitors and foreign attendees. According to the summary of the economic impact analysis, the total exhibition receipts of US$645.7 million produced US$1.2 billion in output; 21 692 full‐time equivalent jobs, US$260 million in personal income for residents, US$577.4 million in value‐added, US$54.2 million in indirect tax and US$104.3 million in imports.

This paper is an assessment of the economic effects of the replacement of means-tested or employment-status-related state redistributive programs by a basic income grant paid unconditionally to all adults without regard to their employment status or pretransfer incomes. A microeconomic model is developed to identify the effects of such a grant on the institutional mechanisms governing the supply of work by those employed and the implied effects on the level of wages, profitability an investment. Two questions are posed. First, taking account of the implied effects on wages, labor discipline and taxes, is it possible to introduce a basic income grant without reducing the level of economy with maintainance of the level of profitability and so, what is the largest grant consistent with maintainance of the level of profitability and investment? The answer to the first question is affirmative. The answer to the second is that for an economy such as the United States, the profitability and investment maintaining grant is small but hardly insignificant; its implementation would effect a major redistribution of income from the employed and the unemployed to the non-employed. 相似文献
