“…Such factors as fear of punishment for non-payment of taxes, as well as guarantees of pension and social security for such people are secondary. The share of the shadow economy in Russia should be reduced, but this should be done not only by repressive measures, but also by creating attractive conditions for legal business [13,20] Thus, it can be concluded that no matter how the state tried to eliminate the shadow economy, no matter what measures and ways it struggled with it, there will still be a shadow sector in any economic activity. The task of each country is only to try to reduce the share of illegal business.…”

“…It should be noted that the regularity of the existence of the shadow economy should be associated with the presence of certain needs of consumers for material goods, property benefits and as long as there is an unsatisfied demand for products of the shadow economy, respectively, there will be a corresponding supply of the shadow sector. This is one of the laws of the free market, it is one of the laws of commodity-money relations [20].…”

An overview of existing approaches to the concept of the shadow economy and its role in the development of the country is given in the article. The authors describe the shadow economy as a socioeconomic phenomenon that has a significant impact on the labor and social situation in Russia, and in particular in the Tyumen region, in connection with which data on the situation in the labor market and informal employment are presented in the article. The analysis of the socioeconomic situation, social and economic policy, which is implemented in modern Russia, is given in the context of social indicators and in relation to other countries. The article is devoted to the study of the shadow economy of Russia in modern conditions. The volume of the largest shadow economies of the world is considered in the article. The main factors determining the scale of the shadow economy in Russia are identified, the statistical data of informal employment are analyzed. The main trends of modern socioeconomic policy are described in the article in connection with the importance of the problem of the shadow economy and informal employment. Measures to reduce the rate of informal employment with a focus on its sources and causes are systematized. 1. Introduction

The article covers the issue of efficiency assessment of individual oil and gas businesses that use key performance indicators. The authors try to improve the efficiency assessment methodology on the basis of SPACE-method. The approach is relevant as it suggests the transition from qualitative efficiency indicators to quantitative ones. The integral estimate for the key performance indicators constitutes the so-called efficiency profile of an organization that has four functional areas, e.g. budgeting, investments, asset and corporate relation management, treasury. The article presents the results of testing the approach in one of the Russian oil and gas businesses. The proposed approach is innovative and valuable from the scientific and practical point of view, and can be introduced in all industries.

This paper is a continuation of research into the causes and ways to eliminate the generation of self-oscillations in the system of automatic regulation of rotations of the free turbine in the turboshaft gas turbine engines of helicopters. The study of dynamic processes in the system of automatic regulation of free turbine’s rotations in a turboshaft GTE has shown that one of the reasons for the development of self-oscillations is the poor performance of the control valve of the type «nozzle-flap» in the rotation regulator’s hydraulic drive. At a pump-regulator plant, the criterion for the quality of control valve execution or repair implies that the geometric size of the valve parts and the flow rate of working fluid through the valve when the flap is closed meet the technical requirements. As practice shows, this is not enough. With this approach, valve defects manifest themselves only during the tests of assemblies as part of the engine. This paper proposes a method to examine the characteristics of control valves such as «nozzle-flap», as well as criteria for assessing the quality of their execution. Experimental characteristics of control valves such as «nozzle-flap» for an actual regulator of free turbine rotation frequency are given. New data on the outflow of liquid from the nozzle with a flap have been obtained. It is shown that the destruction of the stagnation zone in the nozzle tip could result in that the valve flow rate increases, which negatively affects the characteristics of the hydraulic drive and regulator in general. A technique has been proposed to improve the stability of the valve’s performance by increasing the relative length of the nozzle. It is shown that the most informative characteristic of the valve is the dependence of flow rate on the position of the flap. Based on this characteristic, it is possible to determine the criteria for rejecting valves without testing them as part of the assembly
