Conclusions Under the given assumptions, the introduction of an import quota always results in a price increase of the scarce factor. This conclusion confirms that of Falvey [1975] that the Metzler Paradox cannot occur with import quotas. Moreover, we have shown this to be true regardless of the new terms of trade. The introduction of an import quota will, in general, lead to a lower welfare level. This holds for non-prohibitive protection in those situations in which the terms of trade either remain unchanged or worsen. If the terms of trade improve, a higher welfare level can be attained depending on the degree of the improvement and on the size of the quota. The development of the terms of trade can be used as an indication of the price increase of the scarce factor. The more favourable the new terms of trade for the trade restricting country, the greater the advantage accruing to the scarce factor. The effectiveness of the protective measures for distributional purposes coincides thus with the development of the terms of trade.  相似文献

The German federal government’s fiscal consolidation package, announced in June, is designed to permanently reduce the federal deficit to a new target level. This article uses a three-region version of the European Commission’s QUEST model to gauge the impact of the package on Germany and the spillover to the rest of the euro area and the rest of the world.  相似文献

The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient.  相似文献
