Unlike commonly used, anomie and alienation not only have different theoretical backgrounds, but also different indicators and predictors. I examine the highly institutionalized alienation scale originally introduced by Middleton (1963), reapplied as a measurement of alienation (Seeman, 1991) and anomie (Huschka and Mau 2005, 2006) in a very relevant context for an anomic situation – the post-Communist countries Russia and Kazakhstan (round six of the World Values Surveys fielded the alienation question in just these two countries). Based on confirmatory factor analysis and multiple group comparisons, I find that the scale consists of two dimensions, which can be described as an anomie and alienation. The anomic dimension consists of indicators “normlessness” and “powerlessness,” whereas the alienative one is comprised by “social isolation”, “meaninglessness,” and “job dissatisfaction.” Though the structure proves to have full invariance in both countries, the predictors for anomie and alienation are different. For both countries, only income is an important predictor for anomie, and though to a lower degree, for alienation. In Kazakhstan, the level of urbanization also provides an impact on the level of anomie. Apart from income, in Russia alienation can be predicted by gender, and type of occupation (manual or intellectual), whereas in Kazakhstan it can be predicted by age

This paper documents the negative link between the age of Russian cities and their average wage. This link is robust to various definitions of city age and sample censuring, the inclusion of regional and time fixed effects, dependent variable spatial lag and many urban characteristics. This link is revealed especially for cities founded after the Soviet industrialization and for upper quintiles of cities by their average wage. To determine a mechanism behind the established fact, hypotheses as to spatial patterns of economic performance are discussed, including the increasing return hypothesis, the institutions hypothesis and the geography hypothesis. Following the sophisticated version of the geography hypothesis, a model of growth in n-city and two-sector economy is developed. The model replicates the link between age and per capita income and contains testable hypotheses that enable one to check whether a mechanism outlined in the model is behind the link between city age and wage. Our empirical strategy is based on a quasi-experiment, in which the treatment effect is made by time and various age groups of the cities are broken up into treatment and control groups. The results are strongly in favor of the sophisticated geography hypothesis. The revealed mechanism suggests that the changing spatial patterns of wage differentials are explained by the changing remaining stocks of natural resources. Older cities are getting relatively poorer due to the shrinking of their remaining resource stocks, while new cities are emerging in resource-rich territories with the respective income advantages.

We present a new nonparametric method for fitting the term structure of interest rates from bond prices. Our method is a variant of the smoothing spline approach, but within our framework we are able to determine the smoothing coefficient automatically from the data using generalized crossvalidation or maximum likelihood estimates. We present an effective numerical algorithm to simultaneously find the term structure and the optimal smoothing coefficient. Finally, we compare the proposed nonparametric fitting method with other parametric and nonparametric methods to show its superior performance.

This is the first part of a two parts paper dedicated to global bifurcations in the plane. In this part we construct an open set of three parameter families whose topological classification has a numerical invariant that may take an arbitrary positive value. In the second part we construct an open set of six parameter families whose topological classification has a functional invariant. Any germ of a monotonically increasing function may be realized as this invariant. Here "families" are "families of vector fields in the two-sphere".

The Basel Committee of Banking Supervision initiated a discussion on the most efficient practices to prevent bank managers from excessive risk-taking. This paper proposes a game-theoretical approach, describing the decision-making process by a bank manager who chooses his own level of risk and effort. If the level of risk implies the variability of the future outcome, the amount of effort applied affects the probability of a positive outcome. Although effort is unobserved for the bank’s stakeholders, the risk level is under control, and is associated with certain indicators such as capital adequacy ratio or leverage level. The risk-neutral utility function of a bank manager and a binary game outcome of gaining profit or loss for a bank are assumed. Starting from the general incentive contract scheme having the fixed and variable parts of remuneration, it is proposed that differentiating the variable part of remuneration is sufficient to motivate bank managers to make fewer risky decisions. More precisely, the variable part of remuneration (e.g. the share of the bank’s profit) needs to be higher in proportion to the higher variance of outcome for the high -risk outcome case to stimulate a bank manager to opt for lower-risk decisions in place of higher-risk situations.

The aim of this study is to examine the specific antecedents and consequences of the commitment of university teachers to their university. Academia has specific features that distinguish universities from other types of organizations: universities have the opportunity to hire their own graduates (academic inbreeding); university teachers are able to work in several higher education institutions or combine teaching with work in business; university teachers have the opportunity to combine several professional roles (teaching, administrative work, research, etc.); university teachers have several options to change their job; publication activity is an important indicator of the efficiency and competitiveness of university teachers. This study is an online survey of 317 teachers of different disciplines from several types of state higher education institutions from different regions of Russia. The results of the regression analysis show that antecedents of affective commitment include belonging to a group of insiders (working in university from which they graduated), having an additional administrative position, role clarity, and role conflict. Structural equation modelling shows that an additional administrative position had a direct positive effect and an indirect negative effect (through role conflict) on the affective commitment to the university. Having work experience at another university predicts only a normative commitment to the university. The affective component of commitment to the university was a better negative predictor of the intention to leave the position, profession and institution. No components of the commitment predict publication activity.

This paper analyses antitrust enforcement practice in Russia (2008–2012), in the area of competition-restricting agreements (horizontal and vertical). The analysis is based on a court decision database of litigation with the Russian competition authority (FAS). The database contains 400 cases, including 236 horizontal agreements (HA), 164 other agreements (vertical agreements (VA), conglomerate and mixed agreements). On the basis of this database important features of the interpretation and implementation of the competition law in Russian practice and the priority areas of the enforcement were identified. Antitrust policy was analysed taking into account the risks of type 1 and 2 errors, including the problem of the flexibility of prohibitions (per se vs rule of reason (ROR)), standards of proof, the problem of consistency of enforcement

The article sheds light on the scope of transparency in the Russian Official Development Assistance (ODA) and anti-corruption compliance that has been forged by Russian authorities in the field of international development aid. Analysis of official documents, reports and available statistical sources shows quite poor performance of the Russian Federation, especially with regard to the international standards on open aid data and OECD members’ experience.  First, the article lays out the evolution of transparency and accountability standards in international development assistance and highlights the best practices in forging anti-corruption compliance of leading donor organizations and countries. Though it cannot be said with certainty that the level of corruption globally in development aid has diminished, it is obvious that major OECD donor organizations have improved their integrity and managed to render their aid transparent.  This research has been focused on Russian development assistance. Analysis of published information on Russian ODA such as reports by the Ministry of Finance, web-sites of the Ministry of Finance, Ministry of Foreign Affairs and the Rossotrudnichestvo, Concepts on ODA and other published documents showed that apart from procurement mechanisms, Russian authorities have not still forged anti-corruption compliance of its agencies in the filed of international development assistance. Moreover, Russia does not account for its ODA in a sufficient manner. First, the reports of the entitled authorities published on the official websites do not present precise information on Russian projects in development assistance. Though some information is publicly available, it is rather difficult to access to it as it is dispersed across various sources. Second, the functions on ODA are divided among agencies which makes the accountability process more complex. Third, Russia does not meet international standards outlined by the Busan Partnership on enhancing transparency in development aid: Russia does not report neither to the DAC Creditor Reporting System, nor to Forward Spending Survey, nor to the International Aid Transparency Initiative. Though the failure to publish detailed data stem from the lack of institutional capacity of the system of Russian development aid, still more transparency and accountability should be enhanced to enable civil society and scholars to contribute to the development of Russian aid.  The paper concludes with recommendations to Russian responsible authorities on how to make Russian development assistance transparent.

The creation of the EurAsEC Customs Union and Russia’s ascension into the WTO has led to a radical change in Russia’s anti-dumping legislation. Anti-dumping regulation ceased to fall under national jurisdiction and was transferred to the Eurasian Economic Commission, a supranational regulator. This article analyzes the new anti-dumping legislation of the EurAsEC Customs Union, anti-dumping procedures, their principles, participants, an main stages, as well as the legal treatment of inform ation used in the anti-dumping regulation.

We consider an initial-boundary value problem for a 2D time-dependent Schrödinger equation on a semi-infi nite strip. For the Numerov-Crank-Nicolson finite-di fference scheme with discrete transparent boundary conditions, the Strang-type splitting with respect to the potential is applied. For the resulting method, the uniqueness of a solution and the uniform in time L_2-stability (in particular, L_2-conservativeness) are proved. Due to the splitting, an eff ective direct algorithm using FFT in the direction perpendicular to the strip is developed to implement the splitting method for general potential. Numerical results on the tunnel eff ect for smooth and rectangular barriers together with the practical error analysis on refining meshes are included as well.

For Fano manifolds we define Ap\'ery constants and Ap\'ery class as particular limits of ratios of coefficients of solutions of the quantum differential equation. We do numerical computations in case of homogeneous varieties. These numbers are identified to be polynomials in the values of Riemann zeta-function with natural arguments.

The paper offers a taxonomy of the technology platforms (TPs) to help assess a platform’s risk level. TPs are seen as a valuable policy instrument that assists a multi-stakeholder formulation and implementation of long-term R&D programs in specific technology areas at economy or industry level. The TPs analysis and the taxonomy are based on the industrial economic perspective and contribute to defining and implementing technology platforms above the company level. In practical terms the results of the study may be used by policy-makers in designing the R&D support measures. Moreover, the paper clarifies the role of TPs in the science, technology and innovation policy mix. The authors trace the evolution of the ‘technology platform’ concept from an instrument used by companies for R&D and innovation management towards a policy instrument used for technology and economic development at national and international levels. The authors propose a theoretical approach to TPs as a science, technology and innovation policy concept. Furthermore the paper offers a case-study of Russia’s newly established Technology Platforms

We consider fair allocation of indivisible items under additive utilities. When the utilities can be negative, the existence and complexity of an allocation that satisfies Pareto optimality and proportionality up to one item (PROP1) is an open problem. We show that there exists a strongly polynomial-time algorithm that always computes an allocation satisfying Pareto optimality and proportionality up to one item even if the utilities are mixed and the agents have asymmetric weights. We point out that the result does not hold if either of Pareto optimality or PROP1 is replaced with slightly stronger concepts.

The idea that different firms can be classified into relatively homogeneous groups has been popular for many years, and many typologies have been developed and tested using a variety of classification tools. It has become apparent, however, that most clustering tools are somewhat limited, because they create groups of companies based on similar characteristics, without taking into account company performance. The objective of the current study was to address the limitations of previous research by creating a typology of companies based on financial efficiency, using data envelopment analysis as a clustering tool.
