A monopolist sells a luxury genuine product which can be illegally copied and sold by a competitive fringe of counterfeiters. Fines imposed on caught counterfeiters are pocketed by the genuine firm. We prove that if production costs are low, then the genuine manufacturer would lobbying for high penalties so that counterfeiters should be thrown out of the market. In this case, the presence of counterfeiters does not provide any benefit to the producer of the original product. Whenever the production cost is neither too high nor too low, the optimal fine guarantees a positive demand for the genuine product as well as for the fake; the genuine producer is better off than in a world without counterfeiters. If production costs are too high, the genuine firm has no more incentive to produce. Its remaining goal is to collect penalty money from counterfeiters. Again, the presence of counterfeiters provides a benefit to the genuine manufacturer. Finally, a comparison between full protection and null protection policies is performed.  相似文献

In this paper I overview the legislative framework, referred to the Italian policies of tax relief on labour income and Fiscalizzazione, then I investigate the impact of the tax wedge on regional employment in Italy. The results show a negative effect, especially in the northern regions, due to the presence of a developed decentralized bargaining level that may lead to mechanisms of real wage resistance with negative consequences on employment, not only in the short term. The evidence suggests a differentiated effect not only among regions but also among sectors that might suggests to focus these policies on regions and sectors where the effect of the tax wedge on employment is greater, other than to promote the development of a second-level bargaining even in the South that could take into account local labour productivity changes.  相似文献

Improving the well-being of Nigerians is the aim of Nigeria Vision 20:2020, the key development policy document in Nigeria. However, as well-being is an emerging and contested concept, this article explores how the well-being of urban citizens is understood in Nigeria, and identifies key trends affecting urban well-being as expressed by a selection of strategic elite stakeholders in Nigerian society. These included senior civil servants and politicians, and various senior members of civil society groups and academia. The analysis also reveals characteristics underpinning policies for urban well-being.  相似文献

Neither in contemporary sociology nor in legal theory is much attention paid to the theoretical object of commands. This paper explores some features of commands that tend to remain largely invisible in social action, as well as largely under-theorized in the scholarly literature. The analysis draws on early reflection by Elias Canetti and tries to clarify the dynamics of the relationship between law and commands from a sociological perspective. The main claim is that command cannot be reduced to a linguistic entity, but has to be considered in the more complex frame of a direct relationship among subjects and their bodies within a shared space. Explanation of commands is made even more difficult by the fact that they take place in a space that is located ambiguously in between the realm of the subjective and that of the objective, in between passions and institutions. I would like to thank all those who gave me their important and valuable comments to improve earlier versions of this text: Rod Macdonald, Robert Leckey, Giolo Fele, Maria Paola Mittica, Ivan Pupolizio, Isacco Turina, and one anonymous editorial reviewer.  相似文献

Who gets to decide what textbooks are used in America’s public school classrooms varies by state. States can let each school district decide, provide standards that must be followed and make available an incomplete listing of books meeting those standards, or allow schools to choose books only from a list provided by the state. I present a model that provides an explanation for state limits on textbook selection by school districts. I examine the roles played by decision making costs, effectiveness of voters, religious composition, power of teachers, and propensity of state governments to interfere with or to help districts in textbook selection policies at the state level. There has been virtually no research on this topic. My findings corroborate the extant literature that addresses interference by state governments in local affairs and extend the morality politics literature by finding a strong link between religious fundamentalism and state-level policies. I also find that state book lists are less likely (1) in more educated states, where voters are better able to select the most appropriate textbook, (2) in states with smaller school districts, where voters are more involved in the schools, and (3) in states with stronger teacher unions, giving teachers more power in textbook selection.  相似文献

This article analyzes the main motivations behind manned interstellar exploration. There is a wide range of justifications for manned interstellar exploration. Some observers contend that the main reasons are the survival of the human species and the spreading of life in the universe. I argue that the survival of the human species is a very long-term threat and, as such, it is not the main driver for interstellar exploration within a reasonable time horizon. The discovery of habitable planets within 5 to 15 light years from Earth and the possibility that Earth will no longer define the limit of growth constitute stronger motivations. I argue that manned interstellar exploration will be achieved through the mobilization of both public and private resources, as in the past opening of new frontiers, with governments providing initial support in exploration and science, in advancing critical technologies, and in building space infrastructure. The private sector would then take the lead in creating new markets and in expanding humanity’s presence in space.  相似文献
