Given poor tax collection in Mexico –which has registered an average of 10 to 11 percent of the GDP over the last 10 years, while spending has remained around 20 percent–, fiscal reform has been a recurring issue in public debates. In this context, the vat generalization appears as a major option for the country. Nonetheless, its viability has been caught in a discussion tinged with dogmatic hues. This paper presents some important elements that should be taken into account in the debate regarding a generalization of the vat. If the argument for not generalizing this tax is based on the tax’s regressive turn, it should then be stressed that current tax structure has created a situation of greater inequality in terms of the recipients of the support. 相似文献

The literature on liability rules shows that the damage awards under a liability rule affect the efficiency of the rule. One crucial factor that could affect the damage awards and therefore the efficiency characteristics of liability rules is the error made by a court while estimating the harm suffered by the victims. In this paper efficiency property of what we label as 'simple' liability rules when courts make errors in estimation of the damage is studied in a unified framework. The paper provides a characterization of efficient simple liability rules and shows that the biased court errors act to change the efficiency characterization of simple liability rules. A necessary and sufficient condition for a simple liability rule to be efficient in the presence of upper-biased court errors is provided. The analysis is carried out in a quite general framework. 相似文献

This paper describes a sensitive UPLC-MS/MS method for quantification of methadone and 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) in single empty puparial case of Lucilia sericata. Larvae were reared on substrates spiked with different concentrations of methadone (0-4 μg/g). Methadone was quantified in puparia reared on high concentrated substrates (0.8-4 μg/g). The major metabolite of methadone (EDDP) was not detected, confirming rapid elimination of metabolites by the larvae before pupation. The effects of methadone on the development of L. sericata were also investigated. No effect on sex ratio was detected. A significant difference was calculated for emerged adults but no trends could be observed. Concerning the developmental curve, a significant difference was observed between control and high methadone concentrations using the Kolmogorov-Smirnov test. 相似文献

The major thrust of planned development in India has been on employment and income generation and self‐reliance. The study evaluates ex‐post income, output and employment linkages and import intensities of manufacturing sectors using an input‐output model. It shows that among the four broad groups of industries, namely agrobased, non‐agrobased final goods, intermediate and capital goods, agrobased industries through technological interdependence, particularly backward linkages, generate relatively more income and employment and use less imported inputs. The non‐agrobased final goods industries with larger import requirements provide potential for income and employment generation if their required imported inputs are internalised. 相似文献

The path of gradual commercialization of current space applications, such as launch services, satellite communication services, direct broadcasting services, satellite remote sensing and navigation services, and satellite weather monitoring services, will most likely be followed by future activities of use of space resources. Ventures, like mining the natural resources of the Moon and asteroids, are likely to become technologically feasible in the near future. The question is what would be the most appropriate approach to address the future needs of exploitation of space resources: should it remain the exclusive province of state governments; should the private sector take over such space activities; or should a public-private partnership type of venture be encouraged? As state governments are becoming constrained by budget deficits, an increased reliance on private sector involvement in space activities involving the extraction and use of space resources is to be expected. When deciding whether to invest in commercial ventures of resource use exploitation, any potential private investor will be faced with the issues of economic costs, risks, and perceived regulatory barriers. This study argues that the perceived regulatory barriers, i.e., the licensing requirement, the “common heritage of mankind” principle of international space law, and protection of intellectual property rights, are not obstacles to economic development. Governments should provide both policy and regulatory incentives for private sector participation in the area of space natural resource use by funding basic research and development and by sponsoring liability insurance for private ventures among other incentives. 相似文献

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures. 相似文献

Although leadership is typically seen as coming from the leaders of governments and major institutions, a strong case can be made that concerned citizens first articulate important issues and policies that official leaders then pick up and promote. In a market-based society dominated by large corporations, Hirschman's framework of exit, voice, and loyalty can be used to relate consumer and grassroots movements to markets, when participants believe there is no exit and loyalty (or acquiescence) is not an option. While "voice" is usually applied to the individual or consumer level, this article develops the concept of organized voice and illustrates how it has exhibited leadership in the controversial relations between the biotech and pharmaceutical industries and society as a whole. The essay concludes by urging more research on organized voice as a source of leadership and by outlining some important dimensions for researchers to consider. 相似文献
