The paper uses a two–sector efficiency–wage model to analyze the consequences of immigration for a small open economy with a dual labor market. Immigrants are characterized by an (exogenous) return probability. Legal regulations impose preferential hiring of natives or "old" immigrants. As a result, there is sectoral segregation between natives and immigrants, leading to discrimination of the type equal pay for equal work,but unequal "work." In the short run (with sector–specific capital), immigration has a positive first–order impact on natives' welfare if migration policy favors segregation through high return rates or restrictive hiring practices ("guest–worker system"). In the long run, its effect is only determined by factor intensities (2 ¥ 2 model). Finally, the improved integration of migrants yields efficiency gains and improves aggregate welfare of all residents. 相似文献

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital. 相似文献

Nach der Atomkatastrophe in Fukushima hat die Bundesregierung beschlossen, bis Mitte Juni die Zukunft der Atomenergie in Deutschland
zu überdenken. Dabei k?nnen unterschiedlich weitgehende Szenarien betrachtet werden. Sie reichen von einer Rücknahme der im
letzten Herbst beschlossenen Laufzeitverl?ngerung bis hin zum vollkommenen Ausstieg aus der Kernkraft. Die Autoren vertreten
grunds?tzlich die Auffassung, dass die wirtschaftlichen Folgen eines Atomausstiegs zu bew?ltigen sind. Mit einer Steigerung
der Energiepreise muss allerdings gerechnet werden — wie deutlich diese ausf?llt, und welche Referenzwerte herangezogen werden
müssen, h?ngt von vielen Faktoren ab. 相似文献

Germany’s energy turnaround is leading to an increasing integration of photovoltaics (PVs) throughout its distribution grid. To ensure safe grid operation in times of high solar radiation, PV plants must either be throttled back to comply with the feed-in limitation or store a portion of their excess electricity in batteries. This paper presents a grid-optimized operating strategy for PV storage systems based on a Fuzzy Logic Controller that reduces peak feed-in and thus also PV curtailment losses. The Fuzzy Logic Controller uses data on PV power surplus and battery charge level as input variables. To obtain good results, the set of numerical parameters of the membership functions is enhanced by evolutionary programming.The energetic assessment shows that even small electrical storage capacities (<<5?kWh) reduce curtailment losses considerably when using the grid-optimized operating strategy. The economic assessment shows that, in 2016, investments in PV storage systems with large PV plants and small batteries have small (positive) Internal Rates of Return. The system efficiency of the battery storage has a small impact on the profitability of PV storage systems, whereas the cycle stability and the electricity purchase price have a large impact. Moreover, there is an economic benefit for plant operators to switch from the simple to the grid-optimized operating strategy. Solar forecast inaccuracies and variations in load and generation profiles have a negligible impact on the performance of the control algorithm. 相似文献

Despite a variety of measures taken by high‐tax countries, the international fight against tax havens so far remains rather ineffective. This paper introduces offshore lobbying as a possible explanation for this observation. The author analyzes the international fight against tax havens in a two‐country model, in which the onshore country exerts pressure on domestic profit‐shifting firms and the tax haven's government lobbies against this measure. In this framework, he finds that pressure and lobbying are strategic substitutes and that there is an extensive margin incentive for offshore lobbying. Furthermore, when starting at initially high costs for profit shifting, a reduction in these costs leads to fewer profit‐shifting firms. Finally, when allowing for a second low‐tax jurisdiction, the overall level of lobbying increases, but less than proportionally. 相似文献

Earlier experimental evidence indicates that some decision makers under-invest in information when it is costly. This insight is applied to the cost–benefit analysis of the provision of data obtained by satellites. In fields like agriculture, remotely sensed information of great precision can be provided to additional farmers at minimal extra costs if a service for farmers with similar information needs is set up. Here, the tendency to under-invest in information asks for creative solutions by the private sector: bankers may work together with rational producers in setting up the information service and promoting it. However, if producers financial resources are insufficient, public intervention, in the form of a free information service may be necessary.The author would like to thank an anonymous referee, Stephan von Cramon-Taubadel, Sean Flynn, Daniel Heller, and Carlos Lenz and participants of the Lisbon Conference of the International Atlantic Economic Society, particularly Asatoshi Maeshiro, for helpful comments. 相似文献
