This article investigates the impact of perceived age norms on the formation of entrepreneurial intentions in the third age. Age norms refer to those social norms that determine whether establishing and running a business are considered appropriate behavior for a mature individual. An empirical analysis of Finnish individuals finds that norms perceived as permissive of enterprising activity in the third age exert a significant positive influence on entrepreneurial intentions in this segment, even when controlling for the general level of entrepreneurship in the municipalities. This influence is partially mediated by whether the individual has a positive attitude toward entrepreneurship, by how the individual perceives their own ability to start and run a business, by the extent of support from their family and friends they perceive and by the importance of that support to them. Thus, if policy aims to increase enterprising activity in the third-age segment, the portfolio of instruments should include measures that address people’s general awareness of third-age entrepreneurship as a viable, positive and attractive late-career option.  相似文献

The value of statistical life is an essential parameter used in ascribing monetary values to the mortality costs of air pollution in health risk analyses. However, this willingness to pay estimate is virtually non-existent for most developing countries. In the absence of local estimates, two major benefit transfer approaches lend themselves to the estimation of the value of statistical life: the value transfer method and the meta-regression analysis. Using Nigeria as a sample country, we find that the latter method is better tailored than the former for incorporating many characteristics that vary between study sites and policy sites into its benefit transfer application. It is therefore likely to provide more accurate value of statistical life predictions for very low-income countries. Employing the meta-regression method, we find Nigeria’s value of statistical life estimate to be $489,000. Combining this estimate with dose response functions from the epidemiological literature, it follows that if Nigeria had mitigated its 2006 particulate air pollution to the World Health Organisation standards, it could have avoided at least 58,000 premature deaths and recorded an avoided mortality related welfare loss of about $28 billion or 19 % of the nation’s GDP for that year.  相似文献

Abstract.  In this paper we find that the estimates of Armington elasticities (the elasticity of substitution between groups of products identified by country of origin) obtained from multilateral trade data can differ from those obtained from bilateral trade data. In particular, the former tends to be higher than the latter when trade consists largely of intermediate inputs. Given that the variety of intermediate inputs traded across borders is increasing rapidly and that the effect of this increase is not adequately captured in multilateral trade data, the evidence shows that the employment of multilateral trade data to estimate Armington elasticities needs caution.

This study examines the relationship between outsourcing and various aspects of employee well‐being by devoting special attention to the role of occupational restructuring as a conveying mechanism. Using linked employer–employee data, we find that offshoring involves job destruction, especially when the destination is a low‐wage country. In such circumstances, staying employees’ job satisfaction is reduced. However, the relationship between outsourcing and employee well‐being is not entirely negative. Our evidence also shows that offshoring to high‐wage countries stimulates the vertical mobility of employees in affected firms in a manner that improves perceived well‐being, particularly in terms of better prospects for promotion.  相似文献

This study contributes to the literature by examining antecedents to different combinations of management control systems. These combinations include combined use, focusing on the absolute magnitude of the project manager's organic and mechanistic control activities, and the balanced use, that is their relative magnitude. It is proposed that project managers' perceived task uncertainty and tolerance for ambiguity have direct and interaction effects on their balanced and combined use of different combinations of project control. Consistent with the hypotheses, the results show negative relationships between high tolerance for ambiguity and balanced and combined use of organic and mechanistic controls. Further, task uncertainty appears to have a direct, significant negative effect on balanced use, but not on combined use. Furthermore, as proposed, a negative significant interaction effect was found. The results were controlled for project size, project type and level of innovativeness.  相似文献

Previous research on age and entrepreneurship assumed homogeneity and downplayed age-related differences in the motives and aims underlying enterprising behaviour. We argue that the heterogeneity of entrepreneurship influences how the level of entrepreneurial activity varies with age. Using a sample of 2,566 respondents from 27 European countries, we show that entrepreneurial activity increases almost linearly with age for individuals who prefer to only employ themselves (self-employers), whereas it increases up to a critical threshold age (late 40s) and decreases thereafter for those who aspire to hire workers (owner-managers). Age has a considerably smaller effect on entrepreneurial behaviour for those who do not prefer self-employment but are pushed into it by lack of alternative employment opportunities (reluctant entrepreneurs). Our results question the conventional wisdom that entrepreneurial activity declines with age and suggest that effective responses to demographic changes require policy makers to pay close attention to the heterogeneity of entrepreneurial preferences.  相似文献

Prior to the 1990s, the electric power industry was highly regulated across the world. Under a liberalization policy to open markets and to grow competition commenced in the early 1990s, efficient management has become a necessity for companies in this industry. The current study examines the divisional efficiencies of multi-functional, vertically integrated companies seeking to optimize their overall management efficiency. For this purpose, divisional cost data are used as input into a slacks-based measure (SBM) model. This provides divisional efficiency indices based on slacks, as well as one for the larger firm-level management function. Further, given the important role of cost structure, we introduce a modified SBM, named the weighted SBM (WSBM), which directly incorporates division-specific weights into the objective function. Results reveal that the power generation divisions of the companies studied have significant influence on the overall cost, whereas the impact of the other four divisions - transmission, distribution, sales and general administrative - is limited.  相似文献

Different knowledge types have their own specific features and tasks in the learning process. Procedural knowledge is used in craft and technology education when students solve problems individually and share their working knowledge with others. This study presents a detailed analysis of a one student’s learning process in technology education and the procedural knowledge used during learning tasks. Thus, procedural knowledge is mainly produced when acting, and includes students’ goal-directed actions related to the craft, design and technology processes and their learning content. These knowledge practices also include multiple interactions with teachers and other students. The findings show six different knowledge practices: observing, checking and asking, revising, guided representative action, self-directed representative action, and comprehended action. These knowledge practices actively relate to each other, and, in concert, they constitute chains of actions that constitute two different types of procedural knowledge: proactive knowledge and executive knowledge. We conclude by discussing how these knowledge practices can be used to develop our understanding of the teaching and learning of craft, design and technology.  相似文献

This article is a part of a research project aimed to find out how different background variables are related to learning outcomes in technology education related to the school subject Sloyd (craft). The research question of this article is: “How are ninth grade students’ attitudes towards the subject related to their learning outcomes?” The empirical data (n = 4792) was collected by stratified sampling from 152 secondary schools as a part of the Finnish National Board of Education (FNBE) assessment. A shortened Finnish version of the Fennema–Sherman attitude test was carried out in a narrowed sample (n = 1548). The three attitude factors for learners were ‘Liking Sloyd as a school subject’, ‘Experiencing Utility in Sloyd’ and ‘Self-concept in Sloyd’. Structural equation modelling revealed that ‘Experiencing Utility’ predicts learning outcomes while ‘Liking’ and ‘Self-concept’ were interveners. The results suggest more learner-centred pedagogics for developing technology education.  相似文献

We establish a set of stylised facts for trade and trading firms in five market services sectors using comparable firm- and activity-level data from four EU countries. Our analysis shows that exports account for much lower shares of overall sales in the services sectors than in manufacturing. This is because fewer firms are engaged in trade in the services sectors and also because within particular sectors firms trade a lower share of their sales on average. Services producers trade mostly goods, but in terms of value, trade in services is much more important to them than to manufacturers. Larger and more productive firms are more likely to be two-way traders and to engage in both goods and services trade. Trade by services firms is somewhat less dominated by firms that both export and import than trade by manufacturing firms. Few firms export many services or to many countries. The value of services exports is increasing in the number of markets served but not necessarily in the number of services traded.  相似文献
