The effective average tax burden in the European Union and the USA: a computer-based calculation and comparison with the model of the European tax analyzer

In this paper we present a computer-based model (so-called European Tax Analyzer) for the international computation and comparison of company tax burdens. The methodology follows the forward-looking concepts for the measurement of effective average tax rates (EATR) on the basis of a model-firm. The EATR is computed for investments generating economic rents (i.e. pure profits above the market interest rate). In contrast to the prevailing approaches for calculating EATR based on separate and isolate investment projects the model-firm approach allows to calculate EATR for more complex and realistic conditions that are relevant for the decision making. Due to its flexibility another important advantage of the model-firm approach is the possibility to include the most relevant and complex provisions of the tax codes (i.e. tax systems, taxes, tax rates, and tax bases). A concrete computation and comparison of the EATR of corporations and their shareholders in five different countries reveals the wide spread between the national EATR. Moreover, for the time series 1995-2000 it could be shown that the differences between the EATR have declined a little. In spite of this convergence, however, tax distortions of competition did not become significantly less. --Tax burden comparison,capital income taxation,tax competition,tax harmonization in Europe

Prevalence of Cytauxzoon felis (Protista: Apicomplexa) in Feral Cats in Russellville Arkansas

Abstract Cytauxzoon felis (C. felis) is a protozoan hemoparasite of domestic and wild felids. Transmitted by ixodid ticks, the sylvatic reservoir for this organism in North America is the bobcat (Lynx rufus) in which the infection is apparently self-limiting. In domestic cats (Felis catus), C. felis causes a highly fatal disease with a distribution that covers much of the central, southcentral and southeastern U.S. and parallels that of the primary vector, the lone star tick (Amblyomma americanum). Interestingly, there appears to be an increased survival rate in domestic cats in the geographic area of the Ozark Plateau. In this study, convenience blood samples from apparently healthy feral cats were microscopically evaluated for the presence of C. felis merozoites. Positive samples were submitted for PCR confirmation by a commercial laboratory. Results indicated a prevalence of 13% (4/32) in this population. Understanding the prevalence of C. felis infection in feral cats is central to evaluating their potential role as a reservoir for the disease and may also further our understanding about the variable pathogenicity of this organism

Rapid purification of quantum systems by measuring in a feedback-controlled unbiased basis

Rapid-purification by feedback --- specifically, reducing the mean impurity faster than by measurement alone --- can be achieved by making the eigenbasis of the density matrix to be unbiased relative to the measurement basis. Here we further examine the protocol introduced by Combes and Jacobs [Phys.Rev.Lett. {\bf 96}, 010504 (2006)] involving continuous measurement of the observable $J_z$ for a $D$-dimensional system. We rigorously re-derive the lower bound $(2/3)(D+1)$ on the achievable speed-up factor, and also an upper bound, namely $D^2/2$, for all feedback protocols that use measurements in unbiased bases. Finally we extend our results to $n$ independent measurements on a register of $n$ qubits, and derive an upper bound on the achievable speed-up factor that scales linearly with $n$.Comment: v2: published versio

Dynamic Panel Data Models Featuring Endogenous Interaction and Spatially Correlated Errors

We extend the three-step generalized methods of moments (GMM) approach of Kapoor, Kelejian, and Prucha (2007), which corrects for spatially correlated errors in static panel data models, by introducing a spatial lag and a one-period lag of the dependent variable as additional explanatory variables. Combining the extended Kapoor, Kelejian, and Prucha (2007) approach with the dynamic panel data model GMM estimators of Arellano and Bond (1991) and Blundell and Bond (1998) and supplementing the dynamic instruments by lagged and weighted exogenous variables as suggested by Kelejian and Robinson (1993) yields new spatial dynamic panel data estimators. The performance of these spatial dynamic panel data estimators is in- vestigated by means of Monte Carlo simulations. We show that differences in bias as well as root mean squared error between spatial GMM estimates and corresponding GMM estimates in which spatial error correlation is ignored are small.Dynamic panel models;spatial lag;spatial error;GMM estimation

Indicators of financial crises do work! : an early-warning system for six Asian countries

Indicators of financial crisis generally do not have a good track record. This paper presents an early warning system for six countries in Asia, in which indicators do work.We distinguish three types of financial crises, currency crises, banking crises and debt crises, and extract four groups of indicators from the literatureexternal, financial, domestic (real and public), and global indicatorsthat are likely to affect the probability of financial crises. The significance of the indicator groups is tested in a multivariate logit model on a panel of six Asian countries for the period 1970:01-2001:12. An additional feature is that we examine four different currency crisis dating definitions. A within-sample signal extraction experiment reveals that some currency crises dating schemes outperform others.

INDIGENOUS LAND TENURE AND LAND USE IN ALASKA: COMMUNITY IMPACTS OF THE ALASKA NATIVE CLAIMS SETTLEMENT ACT

Through the utilization of qualitative methods such as archival analysis, semi-structured interviewing, comparative and extended case studies, and observation, this paper closely examines two related Alaska Native communities. Our purpose is to document the impact of the Alaska Native Claims Settlement Act of 1971 (ANCSA) on land tenure, land use, and community structure. In all, 41 interviews were conducted, focusing on the following issues: (1) the role of the tribal government in relation to the regional and village corporate structure; (2) the recent changes in traditional land uses; and (3) how group decisions are made regarding land management and distribution of resources. By locating ANCSA within a broader context of economic, political, and cultural globalization that seeks to substitute traditional collective rights in land with individual tenure in a "free market" economy, the findings of this research may carefully and cautiously be applied beyond North America to other indigenous-state struggles regarding control of land and resources.United States. -- [Alaska Native Claims Settlement Act], Indians of North America -- Legal status, laws, etc. -- Alaska, Land tenure -- Law and legislation -- Alaska, Indians of North America -- Alaska -- Claims, Indians of North America -- Land tenure -- Alaska, Indians of North America -- Alaska -- Government relations -- History, Land Economics/Use,

Quantum communication via a continuously monitored dual spin chain

We analyze a recent protocol for the transmission of quantum states via a dual spin chain [Burgarth and Bose, Phys. Rev. A 71, 052315 (2005)] under the constraint that the receiver's measurement strength is finite. That is, we consider the channel where the ideal, instantaneous and complete von Neumann measurements are replaced with a more realistic continuous measurement. We show that for optimal performance the measurement strength must be "tuned" to the channel spin-spin coupling, and once this is done, one is able to achieve a similar transmission rate to that obtained with ideal measurements. The spin chain protocol thus remains effective under measurement constraints.Comment: 5 pages, revtex 4, 3 eps figure
