The paper uses a three-factor (capital, low- and high-skill labor), two-household (low- and high-skill individuals), two-sector trade model to analyze the determinants of voter attitudes towards immigration under direct democracy, and to identify factors that would be coherent with both the observed increase in the skilled–unskilled wage differential and the stiffening attitudes towards low-skill capital-poor immigration. If the import-competing sector is intensive in the use of low-skill labor, and capital is the middle factor, an improvement in the terms of trade or neutral technical progress in the exporting sector leads nationals to oppose immigration of capital-poor low-skill households. An increase in income inequality is also likely to stiffen attitudes towards this type of capital-poor, low-skill immigration prevalent in Europe until recently. 相似文献

In this paper we will analyze the relationship between the value and duration moments of a cash flow and movements in the yield curve. We will show that for changes in the yield curve which can be related to tn , the 1st order changes in the net present value of a cash flow are linearly dependent on the n + lth duration moments, and that the 2nd order changes are dependent on the sum of duration moments of order 2 n + 1 and 2 n + 2. We will use this relationship to tilt tracking portfolios so as to protect them against specific changes in the yield curve. 相似文献

The introduction of traffic management schemes has been one response of the National Parks to the problem of ever-increasing car-borne visitors and the consequent damage caused to the rural environment. By reviewing these schemes and by determining and explaining attitudes towards one particular traffic management experiment, the paper aims to deduce lessons for future policy. The analysis, based on two visitor surveys, suggests that the likelihood of success is improved when schemes are integrated, containing both ‘carrot’ and ‘stick’ elements. Since public perceptions are also found to be pivotal to its success, appropriate marketing of a scheme is vital. The paper concludes, however, that to achieve the fundamental objective of greater accessibility with less mobility, a more wide-ranging marketing effort is required intended to engender a sea change in attitude towards both the car and public transport. 相似文献

In social project appraisal, the policy profile of both distributional welfare weights and the social discount rate has risen considerably in recent years. This fact has important implications for the allocation of funds to social projects and policies in countries, and in unions of countries such as the EU. A key component in the formulae for both welfare weights and the social discount rate is the elasticity of marginal utility of consumption, e. A critical review of existing evidence on e suggests that the UK Treasury's preferred value of unity is too low. New evidence presented in this paper, based on the structure of personal income tax rates, suggests that, on average, for developed countries e is close to 1.4. This particular approach to the estimation of e has previously been under‐utilised by researchers. 相似文献

ABSTRACT Over the past three decades strategic management has become a crucial aspect of business education and practice. At the core of strategic management – linking technique to worldview – is modelling (e.g. value chain, SWOT analysis) whereby the complex elements of strategic thinking are simplified. This accounts in large part for the apparent popularity of strategic management as complex interrelationships are pursued through relatively simple models. Yet has the field of strategic management realized the third order of simulacra? Is strategic management a model of simulation whereby reality has been replaced by hyperreality? A review of the extant literature on strategy explores the study and practice of strategy as a discourse, engulfed by its own truth effects. An examination of the concepts of reflexivity demonstrates the value of a postmodern radical reflexive account through the application of Baudrillard's (1983 , 1988 , 1991 , 1994 ) simulation and simulacra. It is through the development of a radical reflexive discourse of strategy as simulacra, this paper critically examines the study and practice of strategy and the lessons we can take from this perspective. 相似文献

The status quo for school science and technology is unacceptable. While the former often is required for admission to university engineering,
as well as to science programmes, the latter is deemed most appropriate for less able, concrete thinkers. This situation persists,
despite the fact school science tends to generate large groups of citizens who are relatively scientifically and technologically
illiterate, largely as a result of its preoccupation with identifying and training potential scientists and engineers. This
practice is tyrannical. It must be abandoned forthwith. A realistic alternative is a combined technology and science programme
– perhaps called 'technoscience' education – that would treat science and technology as equals. Such courses may, as well,
be more democratic in the sense that technological problem solving often is more natural to everyday situations that everyone
may find useful, not just future scientists or engineers. A framework for combined technology and science courses is described
and defended here. Originally developed through collaborative action research amongst practising teachers of science, the
approach appears to be feasible, under certain – perhaps ideal – conditions. A number of changes to science and technology
education may be necessary for broader implementation, not the least of which is a general retrenchment in expectations for
pre-determined learning, along with adjustments to teacher education. Nevertheless, the approach is recommended because of
its emphasis on: personalization, inclusion, problematization, explicitness, apprenticeship, authenticity, contextualization
and freedom.
