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

The extra vulnerability of industrializing countries to environmental problems and industrial accidents cannot be understood or solved by a ‘normal’ scientific analysis. Aspects of the social and institutional context must be included, through analyses based on post-normal science. The standard two-dimensional classification of PNS is modified to have axes ‘social ‘and institutional vulnerabilities’ and ‘complexity of technological hazards’. The analysis is mainly applied to the case of the relatively rare accidents with catastrophic potential. In these, the deaths per accident in India, Mexico and Brazil are much greater than in the industrialized countries. This discrepancy arises partly from location of such plants near residential communities for marginalized workers and their families. Other socio-political factors are relevant, as the role of these countries in the global production system, the enforcement of safety and planning laws, quality of housing, and lifestyle of residents. Reducing the vulnerability of industrializing countries will therefore require major social policies and a comprehension of the limits of the normal scientific and economic approaches to such problems.  相似文献

This article deals with the vulnerability of the Dutch housing allowance scheme. This scheme can be compared with the British housing benefit. The vulnerability of the scheme has been augmented by the current less favourable economic conditions (stagnating household incomes, increasing unemployment) and the Dutch government's announcement that it plans to reduce housing allowance expenditure. Two scenarios are outlined, which may serve to resolve the danger of exploding housing allowances expenditure in the coming years. If a market‐led scenario is chosen, whereby housing associations strive to achieve market rents, the housing allowance will be transformed into a form of housing voucher, the value of which is not directly related to the actual rental price of the property. In this American‐style model, the value of the vouchers would be linked to a ‘virtual’ rent, say 40% of the average rental price in the region. The housing associations would then lose their special semi‐public status. Under the social housing model, the housing associations would retain their special status provided they aimed to achieve rents somewhat lower than the market level. The housing allowance would remain directly linked to the actual rental price. However, some marked changes would be required to render this system sustainable. The Netherlands cannot avoid having to make this choice. Cet article porte sur la vulnérabilité du régime hollandais d'aide au logement. Celui‐ci est comparable aux prestations britanniques. La fragilité du régime a été accrue par les conditions économiques actuelles moins favorables (stagnation du revenu des ménages, augmentation du chômage) et par l'annonce du gouvernement néderlandais relative à la réduction prévue des dépenses d'allocation‐logement. Sont présentés deux scénarios susceptibles de limiter le risque d'explosion des dépenses d'allocations dans les années à venir. Si l'option choisie est un scénario de marché où les associations pour le logement luttent pour atteindre les loyers du marché, l'allocation‐logement se transformera en ‘bon’ dont la valeur ne sera pas directement liée au montant réel du loyer. Selon ce modèle de type américain, la valeur des ‘bons’ sera fonction d'un loyer ‘virtuel’, soit environ 40% du prix moyen dans la région; les associations perdraient alors leur statut particulier semi‐public. Selon le modèle de logement social, elles conserveraient leur statut, à condition qu'elles cherchent à atteindre des loyers légèrement inférieurs au niveau du marché; l'allocation‐logement serait alors directement liée au montant réel du loyer. Toutefois, pour que le régime subsiste, il faudrait procéder à d'importants changements. Les Pays‐Bas ne peuvent s'épargner ce choix.  相似文献

It appears that programme development in technology education is emerging from an atheoretical perspective. This could be attributed to the absence/neglect of conceptual frameworks (philosophical underpinning) in the development of programmes in technology education. This article explores the role of the content dimension of the 'essential features' of technology and technology education in OBE (Outcomes Based Education) related programme development. An instructional programme was developed using criteria derived from the essential features of technology and technology education. In order to gauge learners' experience, in relation to these essential features, a qualitative case study involving 20 learners was undertaken at a College of Education. Engagement with theprogramme proved to be an empowering experience for the learners who had hitherto not had the opportunity to experience a formal programme in technology education. Although it could not be proved conclusively that cognitive development had occurred, positive inter-dependence,shared responsibility, social skills and enhanced learning were evident. The study has shown that criteria derived from the 'essential features' of technology and technology education could serve as a reliable yardstick to measure the extent of learning in relation to these essential features  相似文献

In this paper we compare alternative asymptotic approximations to the power of the likelihood ratio test used in covariance structure analysis for testing the fit of a model. Alternative expressions for the noncentrality parameter (ncp) lead to different approximations to the power function. It appears that for alternative covariance matrices close to the null hypothesis, the alternative ncp's lead to similar values, while for alternative covariance matrices far from Ho the different expressions for the ncp can conflict substantively. Monte Carlo evidence shows that the ncp proposed in Satorra and Saris (1985) gives the most accurate power approximations.  相似文献

In this paper we investigate the effect of golden parachute (GP) adoptions on shareholder wealth. We control for the potential effect a GP adoption has on the probability that a firm will receive a takeover bid by investigating the wealth effects for firms that are in play when the GP is adopted. We find that announcements are wealth neutral when firms are in play and wealth increasing when firms are not in play when a GP is adopted. The results suggest that GPs have no influence on the success of a tender offer, refuting the hypotheses that they either align manager and shareholder interests or that they entrench inefficient managers. The difference in the results for in-play and not-in-play firms is consistent with the hypothesis that GPs signal an increased likelihood that a firm will receive a takeover bid.  相似文献
