This paper analyses the economic value of foreign languages in Turkey using data on some 6000 adult male wage-earners in 2007. We find positive earnings returns to proficiency in English and Russian, which increase with the level of competence. French and German skills are also positively rewarded, although their return seems mostly linked to the likelihood to hold specific occupations. In contrast, knowing Arabic does not generate an earnings premium. Focusing on English, we check for heterogeneous returns along the conditional earnings distribution. The results are qualitatively invariant when we account for misclassification errors in self-reported English skills. 相似文献

In this paper we use a simple climate model for endogenous environmental technical change in order to analyse the effects on equity and efficiency of placing different degrees of restrictions on trade in the market of pollution permits. The model is obtained by incorporating in Nordhaus and Yang (1996)'s RICE model a notion of induced technical change close to the one proposed in Goulder and Mathai (2000). With the help of such a model, we assess the pros and cons of introducing ceilings on emission trading. In particular, we analyse both the cost effectiveness and the distributional effects of placing restrictions of trading emissions. The analysis takes into account the role of environmental technical change that could be enhanced by emission trade limitations. However, this effect is shown to be offset by the increased abatement cost induced by the larger than optimal adoption of domestic policy measures when ceilings are made binding. Hence, our analysis provides little support for quantitative restrictions of emission trading, even when these restrictions actually have a positive impact of technical change. Even in terms of equity, ceilings find no justification within our theoretical and modelling framework. Indeed, we find that flexibility mechanisms in the presence of endogenous technical change increase equity and that the highest equity levels are achieved without ceilings, both in the short and in the long run. 相似文献

For the United States, the issue of the impact of aggregate economic conditions on legislative election returns has received extensive research. For European countries, however, research is much less plentiful. In particular, multiparty systems such as France and Italy lack study. For both these nations, we find that worsening aggregate economic conditions significantly increase the legislative vote for leftist parties, which have traditionally played an opposition role. Further, these models seem strong enough to provide good prediction of the actual legislative vote share. For example, they manage to forecast the 1981 victory of the left in France, and the 1980 Communist party support in Italy. 相似文献

Mast cell histochemistry has been proposed in addition to classic histological methods to estimate the course of traumatic events before and after death. We have addressed the utility of this approach on nine victims of different types of trauma. Sections of wounded skin were stained with hematoxylin and eosin and with fluorescent avidin to tag mast cells. Mast cell numbers were evaluated by both direct and digitalized counts. Intact skin was used as control. The results on mast cells implemented the findings upon hematoxylin and eosin stain and helped to put the wounds and death in chronological sequence. Digitalized morphometry allowed to reduce intra- and inter-observer variation. We conclude that combined histological and histochemical analyses can be of practical use in forensic pathology, that a preliminary setting of the reference values is needed for each laboratory, and that image analysis can be of help for the quantification of the results. 相似文献

The major issues of medico-legal relevance in fatal falls from a height are the manner of death and the reconstruction of the event. We present a peculiar case of a fatal fall from a height of about 9 m, involving a 27-year-old woman. At the death scene investigation, no suicide notes, housebreaking marks, or signs of fight were found, thus weakening both the suicide and homicide hypotheses. Combining circumstantial, autopsy and toxicology data, the kinematic analysis of the jump/fall, and the histological evidence of a myocardial sarcoidosis involving the left ventricle, we hypothesized that the young woman might have accidentally fallen from the window because of a sudden loss of consciousness related to cardiac disease undiagnosed during life. We believe that our brief report is a good example of the powerful additional information that histological investigations can offer for reconstructing the dynamics of the event in falls from a height and other traumatic fatalities. 相似文献
