In Western Europe in the last two decades the unemployment rate has increased during cyclical downturns only to persist at or around the higher level in the following phase of economic recovery. One of the most notable exceptions to this pattern of unemployment persistence, often termed hysteresis, is the United States. The following article examines the empirical evidence and the possible theoretical explanations for this difference.  相似文献

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.  相似文献

How responsive are migrant remittances to various disasters, both natural and human-made? Would remittances be affected by systemic financial crises, such as the 2008–09 financial crisis, or more recent crises affecting the Eurozone? Using panel data on 23 sub-Saharan African (SSA) countries from 1980 to 2007, we find that remittances are slow to respond to natural disasters, unresponsive to outbreaks of conflict, and will slowly decline following a systemic financial crisis. This suggests that, given its stability, remittances are sources of resilience in SSA.  相似文献

The new product development (NPD) literature emphasizes that the success of new products strongly depends on a firm's capability to understand customer needs and translate them into new products. Because of their close relationships with customers, salespeople are in the ideal position to connect the firm's NPD efforts to its customers. The extant literature on the role of sales in NPD focuses on either sales’ contribution to generating new product ideas or the adoption of new products by salespeople, while a systematic study of sales’ contribution during all NPD stages is lacking. In addition, the role of sales is typically studied in isolation, while in practice, the role of sales depends on the relationship between sales and marketing. This article addresses these gaps in the literature by reporting on an empirical investigation of the role of sales during the entire NPD process in the U.S. health‐care industry, taking into account the complexities of the sales‐marketing dynamic. The article is based on interviews with 21 sales and 15 marketing informants from the U.S. health‐care industry, both pharmaceutical firms (selling drugs to physicians) and device manufacturing firms. Our findings highlight how salespeople are distant from NPD process during the discovery stage. Salespeople are focused on selling to customers, and marketing keeps sales distant from the NPD process. During the development stage, sales is still only indirectly involved in NPD through its relationship with marketing. During commercialization, however, marketing takes the driver's seat and strongly involves sales in the various (pre)launch activities. But while salespeople are mostly indirectly involved in NPD, sales managers have a closer relationship with sales and are more directly involved. The findings also show how the involvement of sales is influenced by characteristics of the health‐care industry. Thus, this article contributes to our understanding of the role of sales in NPD by integrating theoretical perspectives from the sales‐marketing interface literature into the NPD literature.  相似文献

This paper focuses on the organization of new product development in large, R&D‐intensive firms. In these firms, research and development activities are often separated. Research is conducted in dedicated research projects at specialized research labs. Once research results are achieved by research projects, they are transferred to business units for further development and commercialization. We investigate the speed whereby research projects transfer their first research results to business units (hereafter: transfer speed). In particular, we analyze the antecedents and performance implications of transfer speed. Based on data of 503 research projects from a European R&D intensive manufacturing firm, our results suggest that a fast transfer speed (as measured by the time it takes for a research project to develop and transfer its first research result to business units) is associated with a better research performance (as measured by the total number of transfers the research project generates). Moreover, we find that different types of external R&D partners—science‐based and market‐based partners—play distinct roles in speeding up project first research transfers. While market‐based partnerships (i.e., customers and suppliers) generally contribute to a faster transfer of first research results, science‐based partnerships (i.e., universities and research institutions) only speed up first research transfers of technologically very complex projects. Our results also show that early patent filings by research projects accelerate first research transfers.  相似文献

Since the invention of the European Patent System, national patent systems have continued to co-exist, although they did lose appeal. How have the different national systems been affected in view of their characteristics? In order to answer this question a constant-market-share (CMS) analysis is carried out. While on a theoretical level, the different elements adding to the appeal of each patent system are discussed, the CMS-analysis reveals the importance of country size in that the national systems of smaller countries lose.  相似文献

Integrated Science, Technology, Engineering and Mathematics (STEM) education is an emerging approach to improve students’ achievement and interest in STEM disciplines. However, the implementation of integrated STEM education depends strongly on teachers’ competence, which entails, among others, teachers’ attitudes. Nonetheless, not much is known about the factors that influence teachers’ attitudes toward teaching integrated STEM. Therefore this paper uses a survey method to get insight into the relationship between three groups of variables and teachers’ attitudes toward teaching integrated STEM: teacher background characteristics, personal attitudes and school context variables. The results of the multiple regression analyses reveal three variables that are positively linked with teachers’ attitudes: professional development, personal relevance of science and social context. Moreover two variables show a negative correlation: having more than 20 years of teaching experience and experience in mathematics. The results of this study provide valuable information about factors related to teachers’ attitudes toward teaching integrated STEM. Moreover, these results can be deployed by school administrators to guide them when implementing integrated STEM education in their school.  相似文献

For data on market prices for 246 cliquets we consider pricing these exotic options using a relatively simple path space. The path space is subsequently stressed to market implied stress levels as well as stress levels predicted from contract characteristics. An additive process transitioning from a Sato process to a Levy process is formulated and estimated on vanilla options. Ask prices constructed from predicted stress levels are observed to have an in sample correlation of 92% with market prices. Interestingly, it is observed that capped cash flows have negative stress levels while uncapped products have positive stress levels. We illustrate the effect of hedging cliquet liabilities using call options as hedging assets permitting a 10% reduction in ask prices.  相似文献

The Journal of Product Innovation Management (JPIM) was launched in 1984 and over its first two decades of existence evolved into the leading journal in the field of innovation and the management of technology. During these 20 years JPIM contributed to the field by publishing 488 academic papers. This paper is a follow‐up study to an earlier study that looked at how JPIM evolved in terms of knowledge stock and knowledge flows during the first two decades (published in JPIM, March 2007). That paper looked at what was published during the first 20 years, which sources were cited, and which journals cited JPIM papers. This study takes a closer look at the impact of JPIM on the field of innovation and the management of technology by identifying the most classic papers published in JPIM during its first two decades of existence. This study used multiple research methods to identify 64 candidate potential classics from the 488 papers published in the first 20 years of JPIM's existence, to analyze how they differ from the other 424 papers published in the journal, and to investigate authors' motivations for writing these papers. Finally, using survey responses from the Product Development and Management Association (PDMA) membership and other academics in innovation and new product development, the research then determines which 5 of the 64 candidate papers are considered to be the “most classic” papers published and the factors driving that determination. The findings show that classic papers are those presenting a “pioneering idea” in the field that creates buzz in both the academic and practitioner worlds. High numbers of citations are indeed the outcome of these endeavors, but being a classic requires more than having high numbers of citations. Authors of the true classics generally have worked hard to disseminate their research, usually to both academics and practitioners, perhaps also contributing to the network buzz created by their findings. While one of the five most classic papers represented the first investigation into a particular stream of research, the other four were culminations of a significant body of research, providing a distinct summary of known information on a topic at the time they were published and a clear road forward for future research on the topic. These bodies of knowledge have yet to be superseded by other culminating papers.  相似文献
