The Organisation for Economic Co-operation and Development (OECD) proposal for taxation of digital economy constitutes one of the most ambitious projects in the field of taxation and may lead to the most significant reform to international tax rules in the 20th century. Based on a two-pillar approach, Pillar Two of the proposal suggests the adoption of Global Anti-Base Erosion (GloBE) provisions that are aimed at introducing a worldwide minimum tax. In this article, a critical analysis is based that the GloBE proposal suggests that it represents a shift in the OECD policy. As compared to base erosion and profit shifting (BEPS), it jeopardizes the tax sovereignty of jurisdictions and it raises fundamental challenges of implementation, both in terms of amendments to domestic law and conflicts with tax treaties. 相似文献

This work analyses Brazil’s foreign policy in the climate change regime. More specifically, it focuses on two initiatives that Brazil actively promoted, the BASIC coalition, which was established at the COP-15 in Copenhagen, and the concentric circles proposal, forwarded amidst the growing momentum for the COP-21 in Paris. By means of a comparative analysis, I look into three explanatory factors: (i) the structure of the regime; (ii) Brazil’s climate-related advantages; and (iii) its diplomatic expertise, for later seeing to which extent they account for Brazil’s behaviour in climate talks. I conclude that domestic factors played a more prominent role in the advancement of an individual proposal such as the concentric circles than on Brazil’s participation at the BASIC. 相似文献

This study provides one of the first causal estimates of both the personal and partisan incumbency advantages. Using data on six local elections taking place during the last 20 years in 278 municipalities in Portugal, it relies on a reform introducing mayoral term limits as a natural experiment that creates exogenous variation on the incumbency status of officeholders while holding the incumbency status of the party constant. A new methodology combining two quasi‐experimental methods, the regression discontinuity and the difference‐in‐discontinuities designs, allows for a credible estimation of the independent personal and partisan returns to incumbency. Results causally identify the personal effect as the driver of the incumbency advantage. 相似文献

Selectively using Tocqueville, many social scientists suggest that civic participation increases democracy. We go beyond this neo-Tocquevillian model in three ways. First, to capture broader political and economic transformations, we consider different types of participation; results change if we analyze separate participation arenas. Some are declining, but a dramatic finding is the rise of arts and culture. Second, to assess impacts of participation, we study more dimensions of democratic politics, including distinct norms of citizenship and their associated political repertoires. Third, by analyzing global International Social Survey Programme and World Values Survey data, we identify dramatic subcultural differences: the Tocquevillian model is positive, negative, or zero in different subcultures and contexts that we explicate. 相似文献

A clear positive case for anabolic steroids doping was confounded by alleged urine tampering during doping control procedures. Review of the chain of custody showed no flaws, but nevertheless the athlete was adamant that the urine sample should be analyzed for DNA in order to support her contention that she was not the donor of the sample. The results obtained showed that the urine sample that scored positive for steroids contained nuclear DNA that could not be matched to the DNA obtained from the athlete's blood. On the other hand, the same urine sample contained mitochondrial DNA whose nucleotide sequences spanning the hyper variable regions HV1 and HV2 proved to be identical to those determined in mitochondrial DNA amplified from the athlete's blood. The occurrence of an extraneous genotype is compatible with exogenous nuclear DNA admixture to the athlete's urine. Alternatively, taking in consideration the mitochondrial DNA, we could not exclude that a sibling or a maternal relative of the athlete could have acted as a donor of the urine utilized for doping control and DNA analysis. Both situations point to possible tampering of the urine by the athlete. Adjudication at CAS maintained previous national and international federation decision that there was no proof of a chain of custody flaw to justify the athlete's allegation of urine substitution after collection. 相似文献
