This article analyses the Servicios de Administración Tributaria (SAT), which currently operate in nine Peruvian cities, to show that semi‐autonomous tax agencies can play a significant role in strengthening the effectiveness, efficiency and legitimacy of decentralised tax systems. Its findings indicate that the SAT collect local taxes and non‐tax revenues more effectively than conventional tax administrations, and that, although the SAT model per se does not generate strong incentives for the promotion of efficiency, efficiency may become more important once the SAT are consolidated. Finally, there are hints that the Peruvian SAT contribute to the legitimacy of the tax system thanks to higher levels of transparency and client orientation. 相似文献

This study explores the benefits of equine-assisted-activities (EAA) to adolescents with emotional, behavioural or learning
difficulties, expanding on previous anecdotal evidence by employing quantitative measures and a control activity. Ten adolescent
males and one adolescent female attended a racehorse rehabilitation centre, interacting with both live and model horses. Interaction
frequency, self-report anxiety and self-esteem were measured. A significant reduction in trait anxiety was found over the
course of the programme, however, no changes in self-esteem were reported. Such programmes could reduce anxiety in at risk
populations. Further research could deconstruct the study and elucidate the relationships between EAA and psychological well-being. 相似文献

We propose a new model for regression and dependence analysis when addressing spatial data with possibly heavy tails and an asymmetric marginal distribution. We first propose a stationary process with t marginals obtained through scale mixing of a Gaussian process with an inverse square root process with Gamma marginals. We then generalize this construction by considering a skew‐Gaussian process, thus obtaining a process with skew‐t marginal distributions. For the proposed (skew) t process, we study the second‐order and geometrical properties and in the t case, we provide analytic expressions for the bivariate distribution. In an extensive simulation study, we investigate the use of the weighted pairwise likelihood as a method of estimation for the t process. Moreover we compare the performance of the optimal linear predictor of the t process versus the optimal Gaussian predictor. Finally, the effectiveness of our methodology is illustrated by analyzing a georeferenced dataset on maximum temperatures in Australia. 相似文献

We determine how better information affects the average equity premium in a standard representative‐agent exchange economy. Perfect information obviously eliminates the equity premium, and a particular kind of information about the level of future consumption always lowers the average equity premium. Surprisingly, information sometimes raises the average equity premium, no matter what the preferences of the representative agent. Information purely about the volatility either of consumption or the marginal utility of consumption raises the equity premium for a wide class of preferences. Moreover, information can raise the average equity premium by an arbitrarily large percentage (while still matching important magnitudes, such as average growth and the risk‐free rate). We consider two different economies: a two‐period economy with arbitrary preferences for the representative agent; and an infinite horizon economy, in which we restrict both preferences and the endowment distribution. 相似文献
