Restricting CO2 emissions requires changing today's consumption pattern away from energy and emission intensive commodities towards cleaner goods. The cost of stabilizing CO2 emissions at the 1990 level by the year 2000, say, as compared to a business-as-usual trend, is estimated by several researchers to be on the order of 1% of GNP. We will argue that the cost may be overestimated because of a too simple model describing the working of the economic system and the evaluation of welfare. We demonstrate that by expanding a model to include the actual tax system and negative externalities, the cost to present generations from restricting emissions by a CO2 tax may be negative. That is, some reduction may actually correspond to a 'no-regrets' policy. The reasons are inefficiencies in today's tax system and non-optimal handling of negative externalities. Our analysis suggests that a CO2 tax and reduced emissions will lessen such inefficiencies. 相似文献
We examine how tax avoidance in the form of trade in well-functioning asset markets affects the study of labor supply. We discuss the implications for tax policy analysis, and we show that a failure to account for avoidance responses may lead to huge errors when analyzing how tax reform affects labor supply, tax revenue and the welfare cost of taxation. Our model may explain a number of otherwise hard to understand dimensions of taxpayer response. 相似文献
In a longstanding debate among economic historians about the role of the peasants and the manors in the agrarian transformation, a variety of qualitative and quantitative indicators have been used, but no one has until now been able to compare the actual production outcomes. In this paper, we investigate the land productivity development for manorial demesnes and peasant farmers, respectively, over the course of the agricultural revolution. The sources used are unique in an international perspective and consists of tithes on individual farm level for 34 parishes in Scania, covering over 2500 peasant farms, which are compared with production data for 20 manorial demesnes.
The study generates vital information on the process of agricultural transformation and its leading actors. We assess the implications of the productivity development for the total production, and the spectacular growth in this under the agricultural revolution, by calculating production and surplus among the different types of cultivators. Our results show that the landlords gained a small advantage in the middle of the 1700s, but in the century to come, they lagged behind in terms of land productivity. A large peasantry cultivating the majority of the land did not constitute an obstacle to growth, but rather the reverse. 相似文献
Researchers have established a relationship between greater education and training and higher earnings but it is difficult to infer that the former causes the latter if those with higher earnings tend to engage in more education and training. The present study attempts to control for ability and family background to see if stronger inferences can be made about education and training as the independent variable. The study focuses upon advanced vocational education and training (AVET) in Sweden. This is post‐secondary school education for individuals who are 20 years of age or older. The aim of this article is to estimate the effects of AVET on earnings by controlling for selection bias. We used various approaches such as instrumental variables, Hausman–Taylor estimates, fixed effects estimates and propensity score matching to achieve this aim. A panel, or longitudinal, data set for eight different labor markets in Sweden for the period 1996–2008 was used. The results indicate that earnings from AVET are higher than the return on investment in comprehensive education. The average effect on income is estimated to be in the range of 3–8 percent. 相似文献
The objective of this study was to evaluate the effect of a community-based injury prevention program on home injuries. Unintentional injuries occurring in private homes and during leisure time account for 70-80% of injuries treated in public health care. A quasiexperimental design was used for the study, with cross-sectional preand post-implementation measurements in the program area and in a neighboring control community. Children and the elderly were two main target groups of the intervention program, which was based on a participative strategy for community involvement. The study was based on defined total populations. The total relative risk for home injury occurrence decreased in the study area, whereas it increased in the control area. Regarding age and gender, there was a decrease for females and males in the study area and a slight increase in the control area. For males, the youngest and oldest age groups showed no decrease, whereas females showed a decrease among the youngest and those aged 60-79. No decrease was observed in the control area. The study showed that the Safe Community approach had a general effect on the incidence of home injuries. 相似文献
Although best practice transfer methodologies have become an increasingly common instrument in enterprise policy development, barriers to the exchange and dissemination of knowledge may limit their effectiveness. Using START, an EC-funded network of regional agencies, as a case this paper explores the dynamics of experience exchange in regional enterprise policy. Working closely with the START partnership, the authors developed a detailed account of how the network communicated and disseminated cases and instances of regional start-up policy and practice between themselves. Partners in START were more likely to adapt abstracted principles, concepts and ideas that informed changes to their own practices than to adopt specific initiatives from other regions. This suggests a need to re-focus best practice transfer methodologies away from the transplantation of established practices towards encouraging interactive and collaborative learning based on the sharing of experience. 相似文献
