Abstract: The article deals with the phenomenon of imbalance of the tax system in the market economy conditions. The authors of the article offer their definition of the imbalance of the country's tax system as a combination of various kinds and forms of the disproportions within its structure that have reached critical scales and thus started to influence the country's tax system. The authors also analyze its causes and conditions and describe processes, phenomena and problems that disturb the balance of the country's tax system. The authors also list the results of the presence of such disproportions in the tax field and give examples of the imbalance of rights and obligations of taxpayers and government agencies. In the course of their research the authors have used general and special sciences research methods such as analysis, synthesis, deduction method, comparative law methods, etc. The topic of the imbalance within the taxation system still needs to be studied further. The authors suppose that science needs to study processes, phenomena and problems that distort the balance of the country's tax system, thus creating a threat for the economic security of the cuontry. In this article the authors offer particular ways of improving the tax system and restoring the disturbed balance. It is concluded that the improvement of the country's tax legislation should be based on the principles (criteria) of efficiency and neutrality of the tax system.

Abstract: The article analyzes the evolution of antitrust law of the USA. The authors consider the Sherman Act, the Clayton Act, the Robinson-Patman Act and other laws which form the basis of the modern antitrust legislation of the USA. The authors enumerate the bodies responsible for antitrust regulation. The article contains the conclusion that the successful experience of the USA in the sphere of antitrust regulation can be used in Russia, particularly, in relation to preventive measures. The authors carry out the comparative-legal study of antitrust legislation of the USA and Russia. The authors apply the historical method (to study the retrospective of antitrust legislation of the USA) and the comparative-legal analysis (when comparing American and Russian legislation). The scientific novelty of the study consists in the analysis of American experience in the sphere of antitrust regulation and the possibility to use it in Russia. The authors conclude that it would be reasonable to use American experience in the sphere of preventive institutions in Russian system of antitrust regulation, broadening of powers of antimonopoly service and globalization of antimonopoly legislation. 

Abstract: The object of the research is the relations arising in the process of imposing and collection of taxes. The subject under analysis is the process of taxation of so-called 'luxury goods' in various countries. In their article Pogodina and Borisova analyzes foreign experience in taxation of 'excess profits', expensive transport facilities and real assets. They also examine foreign experience in collecting 'luxury' tax and granting tax privileges. They describe the cases when 'luxury tax' is abolished and prove the usefulness of imposing luxury tax within the framework of transport tax and single tax for real assets in Russia. The methodological basis of the research involves the comparative legal method. The authors have also applied the methods of analysis and historical research. The novelty of the article is caused by the fact that the author provides a comprehensive analysis of the process of taxation of luxury goods (items) in different countries (Great Britain, Hungary, Spain, People's Republic of China, Norway and France). In conclusion the authors suggest that it would be useful to implement the mechanism of taxation of luxury items within the framework of transport tax and real estate tax. 

Abstract: The object of studies of the author concerns investment processes at the level of constituent subjects of the Russian Federation. The object includes indicator criteria for innovative modernization in the regions. It is obvious that investment resources guarantee modern equipment, electronic information system and high quality personnel for the enterprises. These enterprises play key role in the innovative modernization of economics in the region. The main branch of the strategic plan in the state should include the structural modernization nucleus for the high technology spheres. That is why there is need to develop methods, allowing to correlate perspective criteria of social and economic development of the regions, serving as indicators for the innovation modernization in the constituent subjects of the Russian Federation. In order to optimize the structure of the said indicators and to substantiate the direction of innovative investment program of social and economic regional development the authors offer to use the Pareto law. The Pareto analysis allows to range certain spheres and matters depending on tehir importance and calls for revealing and abolishing of the causes of hte most problems (inconsistencies). The use of group of branch indexes characterising the perspectives of functioning may be applied to certain sub-types or groups of goods (services), which may be of interest from the standpoing of viability of investments, as well as to types of economic activities within the state or a certain region. In the use of Pareto law and ABC-analysis when forming an optimum scheme for the investment distrtibution for the innovative modernization of regional economics it seems viable to suppose that types of economic activity related to the production of other non-metallic mineral product, machines and equipment are rather valuable on one hand, but on the other hand they cause the most problems.
As it may be seen from the Pareto map formed within the program complex Statistica 6.1, the dominant types of processing industry of the region includes foodstuffs production, electric equipment production, machinery and equipment production, and production of non-metallic mineral products. That is why it is necessary to define optimization in these economic sectors. The authors then try to find out whether such optimization is necessary in the Vladimir region of Russia. Considering the large amount of inefficient capacities, there is need for the rapid growth of investments in the modernization of the production apparatus. In order to provide reaction analysis for the types of economic activity according to the list for the changes in the dynamics of the basic amount of economic markers, the authors offer to use correlations of the growth tempos, which may be presented as development indexes and evaluated according to the base index calculation formula.
