This paper explores the patterns of citations among patents taken out by inventors in the U.S., the U.K., Francc. Germany and Japan. We find (I) patents assigned to the same firm are more likely to cite each other, and come sooncr than other citations; (2) patents in the same patent class are approxinlatcly 100 titlles as likely to cite each other as ydtents froin different patent classes, but there is not a strong time pattern to this effect; (3) patents whose inventors reside in the same country are typically 30 to 80% more likely to cite each other than inventors from othcr countrics, and these citations come sooner; and (4) there are clear country-specific citation tendencies, e.g., Japanese citations typically come sooner than those of othcr countries. 相似文献

Knowledge is increasingly perceived as a fulcral factor to company competitiveness. As the transfer of knowledge is one of the key functions of knowledge intensive business services (KIBS), this research seeks to analyse how the transfer of knowledge takes place between the higher education sector and KIBS type firms. The empirical results show that cooperation between KIBS and universities occurs irrespective of the typology (whether professional or technological in focus). We also empirically establish how geographic proximity is the factor bearing greatest influence over cooperation while such cooperation proves to have a positive impact on the company capacity to innovate. We furthermore find that this innovation capacity also drives a positive company financial performance. 相似文献

This article aims to identify the cognitive factors which influence the consumer attitudes toward the purchase of the airline ticket. We refer to the comparison between the beliefs regarding self-service and the alternative service or traditional service. This study is based on a sample of 739 Spanish undergraduates and their attitudes toward buying an airline ticket. This is the best selling product on the Internet in Spain. We compare the beliefs in two segments—online consumers and offline consumers—regarding each of the two systems for air ticket purchasing: Internet versus traditional travel agency. Hence, in online consumers, control and delivery speed are observed to be differentiating cognitive factors in the use of a self-service system. However, with offline consumers, delivery speed is indicated as a particularly significant cognitive factor in the use of the traditional service system. 相似文献

This study measured membership changes in private clubs in the United States during the economic downturn from 2008 to 2010. Specifically examined were the changes clubs experienced with their number of members, waiting lists, and attrition rates. A letter was sent via e-mail to the same 1,000 private clubs that were sent a survey in a similar study conducted by Ferreira and Gustafson (2006) The managers of these clubs were members of the Club Managers Association of America. The majority of respondents managed country clubs and member-owned clubs, representing different areas of the United States. An overall response rate of 53% was achieved. Most clubs experienced a decrease in the overall number of members and an increase in annual attrition rate. Fewer clubs reported having a waiting list of members wanting to join. The clubs without waiting lists reported a larger number of membership openings in their clubs. The results of this study suggest the levels of memberships in many private clubs are heavily influenced by economic conditions. An implication from this study is that clubs need to implement membership development strategies during economic downturns because of the decline in the number of members, candidates proposed, and waiting lists during these periods. 相似文献

Recent evidence suggests that future performance is predictable from past performance, that is, funds with superior (inferior) performance in the past are likely to remain good (bad) performers in the future. This research addresses the persistence of mutual fund performance in a European regional market (the Portuguese equity fund market). Some of the problems in evaluating fund persistence are identified in the context of limited sample size and using the peer group median as a benchmark for contingency table analysis of performance persistence. The criteria for assessing performance persistence based on the contingency table methodology of repeated winners and losers are presented in terms of significance statistics, adjusted for small sample bias. The adjustments are accomplished through the Yates continuity correction and Fisher's exact p-value. The appropriateness of each criteria under different circumstances is also discussed. The analysis of the returns of all Portuguese domestic equity funds, since a representative number was established, shows some performance persistence (on a quarterly basis). The persistence, however, is reduced when the returns are controlled for the various dimensions of risk. Significant risk persistence has been documented. Furthermore, for more or less frequent intervals of measurement, the industry persistence is rejected, although individual funds exhibit superior/inferior performance. 相似文献

This article draws from the experience of the ongoing drafting of the Regional Plan of the Centre Region of Portugal, and the empirical application of the Social Vulnerability Index proposed by Susan Cutter. It consists in the construction of an index of social vulnerability to natural and technological hazards and to social risks for all the municipalities of the region. Methodologically, it extends the vulnerability analysis to technological hazards and social risks, as a more encompassing view is necessary for the elaboration of prevention and civil protection policies. The results confirm the interactive nature of social vulnerability, and they also reflect the diffuse urbanisation and industrialisation patterns that characterise Portugal. The scattered nature of social facilities and security and health infrastructures pose specific challenges to planners concerning risk prevention and mitigation, and the elaboration of effective risk communication strategies adapted to specific hazards and risks in the studied municipalities. The article concludes with some reflections on the need to revise established paradigms of disaster analysis and emphasise the importance of pre‐event planning and the social cartography of vulnerable populations for effective prevention and security policies that take into account social inequalities and citizenship rights. 相似文献

A leading explanation for the lack of widespread mortgage renegotiation is the existence of frictions in the mortgage securitization process. This paper finds similarly small renegotiation rates for securitized loans and loans held on banks' balance sheets that become seriously delinquent, in particular during the early part of the financial crisis. We argue that information issues endemic to home mortgages, where lenders negotiate with large numbers of borrowers, lead to barriers in renegotiation. Consistent with the theory, renegotiation rates are strongly negatively correlated with the degree of informational asymmetries between borrowers and lenders over the course of the crisis. 相似文献

The introduction of the flex-fuel cars in the Brazilian market in 2003 changed considerably the consumer decision-making process. Prior to this date, it was necessary to choose the automobile type only by gasoline or by ethanol fuel; today it is possible to choose a car type with both fuel options. This flexibility generates economic advantages for his owner, but what are the financial benefits of a flex-fuel car in comparison with a car using only gasoline? Geographically, where is the owner of the benefits from this flexibility located? This article presents an empirical application of the Real Options Theory in the analysis of the flex-fuel car option for five geographic Brazilian regions: Northern, Northeastern, Central-Western, Southeastern and Southern. The regional price differences as well as the consumer preferences of these regions were met. For this purpose, historical fuel prices were considered stochastic and following a Mean Reverting Stochastic process. The prediction and option values were generated by a Monte Carlo simulation. The results indicated that the option embedded on the Brazilian flex-fuel car adds considerable value to the owner in all regions and car models considered, with the Southeastern Region receiving most benefits by the flex option. 相似文献

This note acknowledges and corrects a programming error in our paper “Inequality of Opportunity in Brazil” (Review of Income and Wealth, 53(4), 585–618, 2007). Once the error is corrected, our bounds approach to the identification of individual model parameters in the presence of omitted variable biases is much less useful than indicated in the original paper. In the specific context of the measurement of inequality of opportunity, this implies that the decomposition of overall inequality of opportunity into direct and indirect effects is not reliable. However, the parametric approach introduced in our paper remains useful for obtaining a lower‐bound estimate of overall ex‐ante inequality of opportunity, as proposed by Ferreira and Gignoux (2011). 相似文献
