论商标反向假冒行为及其法律规制   总被引:3,自引:0,他引:3  
商标反向假冒行为妨碍了他人对自己商标的正常使用,扰乱了正常的市场秩序,欺骗了广大消费者和公众。很多国家的立法都明文对其进行规制,我国现行法律亦从不同角度对其进行规制。当前,对严重的商标反向假冒行为,应予以刑法调整。  相似文献

Learning-by-doing and input demand of a rate-of-return regulated firm   总被引:1,自引:0,他引:1  
The significance of learning by doing to input demand of a cost-minimizing rate-of-return-regulated firm is examined. Using a panel data, the results indicate that the firm's cost and input demand decisions are both influenced by learning-by-doing. The firm's cost and the rate-base (capital) input requirements decline as learning-by-doing measured by cumulative production expands. However, LBD may have different effects on the non-rate-base inputs (labor and fuel) considered in this study. While LBD ambiguously reduces fuel usage, it moderately increases labor employment. In addition to changing input intensity, LBD also influences returns to scale and elasticity of substitution.  相似文献

In this paper, we present a two-country trade model with external economies of scale that emerge on an international level but are partially localized in each country. First, we show that the larger country exports the good produced in an industry with external economies of scale in the trading equilibrium. Second, we investigate the welfare effects of trade for the following two cases: (I) the case where external economies are completely localized in autarky; (II) the case where external economies are internationally effective in autarky. In case (II), it is shown that trade can be welfare-decreasing for both countries.  相似文献

Burn or bury? A social cost comparison of final waste disposal methods   总被引:1,自引:0,他引:1  
This paper evaluates the two well-known final waste disposal methods, incineration and landfilling. In particular we compare the social cost of two best-available technologies using a point estimate based on private and environmental cost data for the Netherlands. Not only does our comparison allow for Waste-to-Energy incineration plants but for landfills as well. The data provide support for the widespread policy preference for incineration over landfilling only if the analysis is restricted to environmental costs alone and includes savings of both energy and material recovery. Gross private costs, however, are so much higher for incineration, that landfilling is the social cost minimizing option at the margin even in a densely populated country such as the Netherlands. Furthermore, we show that our result generalizes to other European countries and probably to the USA. Implications for waste policy are discussed as well. Proper treatment of and energy recovery from landfills seem to be the most important targets for waste policy. Finally, WTE plants are a very expensive way to save on climate change emissions.  相似文献

The main objective of this paper is to use the Markov regime‐switching modelling framework to describe and analyse the credibility of a number of countries participating in the European Monetary System during 1980–1998. Our credibility indicator, based on Hughes Hallet et al.'s (1997) methodology, is subject to discrete regime shifts and is made dependent on macroeconomic fundamentals. We carry out extensive testing to assess the specification of the Markov regime‐switching model and the potential existence of permanent breaks. A contribution of our paper is the specification of a multivariate Markov switching model that allows us to examine whether macroeconomic variables have asymmetric effects on credibility. Another contribution is the specification of a regime‐switching model with time‐varying transition probabilities, which enables us to determine whether changes in macroeconomic variables can trigger switches between the low and high credibility regimes. We find strong evidence of regime switching behaviour in all countries. Both the level of credibility and the transition probabilities display an asymmetric response to changes in macroeconomic variables, with the stance of fiscal policy exerting the most systematic influence in all countries.  相似文献

A model of the origins of basic property rights   总被引:1,自引:0,他引:1  
This paper studies the origins of one of the most basic of property rights, namely, the right of an individual or an organization to the fruits of its labour. My objective is to address the questions of why, when and how this property right can emerge and be made secure. I develop a model of the strategic interaction between two players in the state-of-nature, which is an environment characterized by the absence of any laws and institutions (including property rights and the state). My analysis explores, in particular, the roles of the players' fighting and productive skills on the emergence and security (or otherwise) of this property right.  相似文献
