Portugal has a unitary system in which the central government transfers funds to lower government levels for their public functions. In 2007, Portugal introduced Ecological Fiscal Transfers (EFT), where municipalities receive transfers for hosting protected areas (PA). We study whether introducing EFT in Portugal incentivized municipalities to designate PA and has led to a decentralization of conservation decisions. We employ a Bayesian structural time series approach to estimate the effect of introducing EFT in comparison to a simulated counterfactual time series. Quantitative results show a significant increase in the ratio of municipal and national PA designations following Portugal’s EFT introduction—which we infer to be a causal consequence. The analysis furthermore places emphasis on the importance of relevant municipal conservation competencies for the functioning of the instrument. Results have important implications for conservation policy-making in terms of allocating budgets and competencies in multi-level governments. 相似文献

The geological conditions in Germany allow maximum temperatures between 160 to 170°C free well head taking techno-economic constraint into consideration. This makes an electricity production for purely technical reasons possible, but only with low efficiencies due to physical constraints. That’s why it assault big amounts of waste heat. For example, the existing geothermal power plants in Germany provide in average 18% of electricity and 82% of heat. This heat is use so far only to a very small degree. Even is a district heating system is operated to supply private households, this heat is used with less than 2.500 h per year. That’s why the still hot thermal water is press back into the underground without any further utilization. For these reasons to achieve a technical and economic optimization it should be the aim to find different reasonable options to use this waste heat. One possibility is the coupling with a drying process at the location of the geothermal plant. Such options will be analyzed from a technical and economic point of view and some conclusions will be drawn. 相似文献

Previous research indicates that firms pay a premium to poach workers from exporting firms if experience working for an internationally engaged firm reduces trade costs. Because international experience is less valuable to non-exporters, we would expect to see differences in recruitments between firms that are internationally engaged and those that serve only the domestic market. Moreover, increased openness might lead to higher job-to-job mobility if more globalization raises both the share of exporters and the number of workers with skills that make them attractive for other exporters. Using linked Swedish employer–employee data for the period 1997 to 2013, we find systematic differences between the way exporters and non-exporters recruit workers: exporters have a relatively high share of recruitments from other exporters as hypothesized. We also find some suggestive evidence that increased openness correlates positively with upward mobility for occupations that play a major role in international commerce, such as professionals and managers. 相似文献
