We present data from an international survey of scientists working at volcanic observatories concerning eruption likelihoods. The scientists were asked a range of questions using different types of phrasing. The data suggest that the phrasing of questions affects the ways in which probabilities are estimated. In total, 71% of respondents (N = 70) exhibited some form of inconsistency in their answers between and/or within different question formats. The data also allow for an analysis of the use of scaling in probabilistic assessment, and the use of quantitative versus verbal risk measurements. However, some respondents were uncomfortable with providing any numerical probability estimate, perhaps suggesting that they considered the uncertainty too high for meaningful judgements to be made. 相似文献

This case teaches students how discrete (job order) manufacturing companies use Manufacturing Resource Planning (MRP II) within Enterprise Resource Planning (ERP) systems to plan purchase orders for direct materials and shop orders for work‐in‐process and finished goods. Students simulate MRP II integrated within ERP, using Microsoft Excel to learn MRP II's bill‐of‐materials (BOM) Explosion that plans order quantities and MRP II's scheduling logic that uses lead‐times to determine start dates for planned orders. Students explain why MRP II is most practical and effective when executed within ERP and how MRP II can reduce excess inventories, prevent inventory shortages, and help companies deliver quality products to customers on schedule. Also, students explain why BOM, inventory, and lead‐time inaccuracies can adversely affect the accuracy of MRP II‐planned replenishments and identify controls that reduce the risks of these inaccuracies. 相似文献

Social capital is a popular, but contested concept. It draws attention to the way in which social relations and constructed forms of social organization can produce outcomes on individual and collective levels. However, it is often founded on individualistic, rational-choice models of human behavior that neglect its embeddedness. I explore the embeddedness of social capital through a comparative case study of two voluntary sport organizations in the UK. Through close analysis of in-depth interviews and longitudinal observation, I look at the processes of social capital development and the way socio-organizational context and identity shape these processes. 相似文献

Research and development (R&D) is a key factor enabling firms to gather information, create knowledge and innovate. Although often seen as the preserve of goods-producing sectors, knowledge-intensive business services (KIBS) in particular also engage in R&D. In this paper, we are interested in understanding the determinants of R&D in KIBS. We address this question by exploring factors connected to R&D in KIBS, with attention to whether it is connected with internal capabilities or to establishments' openness. We show that KIBS' R&D is associated with internal capabilities, and that recourse to external R&D is part of a strategy of openness that complements internal capacity. We also suggest that KIBS's own view of R&D is aligned with R&D in the goods-producing sector, leading establishments in non-technological KIBS sectors to under-report R&D. 相似文献

Objective: To provide updated evidence on US trends in: market exclusivity periods (MEPs, time between brand-name drug launch and first generic competitors) for new molecular entities (NMEs); likelihood, timing and number of Hatch-Waxman Act Paragraph IV patent challenges; and generic drug penetration.Methods: This study used IMS Health National Sales PerspectivesTM US data to calculate MEPs for the 288 NMEs experiencing initial generic entry between January 1995 and December 2014, the number of generic competitors for 12 months afterward (by level of annual sales prior to generic entry), and generic penetration rates. The likelihood, timing and number of Paragraph IV challengers were calculated using data from Abbreviated New Drug Approval (ANDA) letters, the FDA website, public information searches, and ParagraphFour.com.Results: For drugs experiencing initial generic entry in 2013–2014, the MEP was 12.5 years for drugs with sales greater than $250 million (in 2008 dollars) in the year prior to generic entry ($250 million?+?NMEs), 13.6 years overall. After generic entry, brands rapidly lost sales, with their average unit share being 7% at 1 year for $250 million?+?NMEs, 12% overall. Ninety-four percent of $250 million?+?NMEs experiencing initial generic entry in 2013–2014 had faced at least one Paragraph IV challenge, an average of 5.2 years after brand launch (76% and 5.9 years for all NMEs). NMEs faced an average of 5.1 and 6.2 Paragraph IV challenges per NME, for all and $250 million?+?NMEs, respectively.Limitations: Analyses, including Paragraph IV calculations, were restricted to NMEs where generic entry had occurred.Conclusion: The average 2013–2014 MEP of 12.5 years for $250 million?+?NMEs, 13.6 overall remains consistent with prior research. MEPs are lower, and Paragraph IV challenges are more frequent and occur earlier for $250 million?+?drugs. Generic share erosion is also greater, and continues to intensify for both NME types. 相似文献

We examine the effects of biased (conservative or liberal) reporting on product market competition. Cournot duopolists observe either firm-specific or industry-wide shocks and provide noisy reports subject to an exogenous mandated bias attributed to public policy. Given neutral prior beliefs, either a conservative bias or a liberal bias enhances overall reporting-system informativeness as measured by the reduction of uncertainty. Consistent with previously established effects in the information sharing literature regarding increases in informativeness, we show that expected industry profits and expected consumer surplus may gain or lose from bias, depending on whether the shocks are firm-specific or industry-wide and the degree of product competition. Expected social welfare, however, always increases in bias, irrespective of the source of uncertainty and product substitutability or complementarity. We next consider a setting where firms self-select whether to bias reports and characterize regions of potential conflict with a public policy that maximizes expected social welfare. Further results on the differential effects of conservative or liberal bias follow from relaxing the assumption of neutral prior beliefs. 相似文献

This research tests whether Holderness Jr., D. K., Myers, N., Summers, S. L., & Wood, D. A. [(2014). Accounting education research: Ranking institutions and individual scholars. Issues in Accounting Education, 29(1), 87–115] accounting-education rankings are sensitive to a change in the set of journals used. It provides updated rankings for accounting-education authors from Australia, Canada, New Zealand, the Republic of Ireland, the United Kingdom, and the United States using a sample that included the publications in 13 accounting-education journals. Our analysis indicated that Holderness et al.’s rankings of authors and departments were significantly different from our rankings. This research provides rankings of the top 50 authors and departments for three periods: from 2010 to 2015, from 2004 to 2015, and from 1992 to 2015. We provide data indicating the distribution of authors for these periods to assist authors not listed in the most prolific lists in determining their relative ranking. Finally, we provide data on the distribution of journal choices for accounting-education publications for the authors from each country. 相似文献

We study business cycle fluctuations in heterogeneous agent general equilibrium models featuring intensive and extensive margins of labor supply. A nonlinear mapping from time devoted to work to labor services generates operative extensive and intensive margins. Our model captures the salient features of the empirical distribution of hours worked, including how individuals transit within this distribution. We study how various specifications influence labor supply responses to aggregate technology shocks and find that abstracting from intensive margin adjustment can have large effects on the volatility of aggregate hours even if fluctuations along the intensive margin are small. 相似文献
