The reform of budget-sector entities enables us to compare the impact of different types of public procurement regulations in budget and autonomous organizations in Russia. Such analysis is important in light of the critical discussion of the effects of current procurement regulation (94-FL), as well as taking into account the introduction of the Federal Contract System in 2014. Using the difference-in-differences methodology, we shall consider public procurements of two national universities in 2011–2012. All procurements of the first university were regulated by the 94-FL requirements. Procurements of the second university were regulated by the 94-FL until June 2011. Later this university introduced its own Procurements Provision. A comparative analysis of procurements of these organizations enables us to estimate the impact of the different types of regulations on the effectiveness of public procurement, as measured by the level of competition and price decline in public tenders, as well as the timely execution of procurement contracts.

This paper presents a novel combinatorial approach for voting rule analysis. Applying reversal symmetry, we introduce a new class of preference profiles and a new representation (bracelet representation). By applying an impartial, anonymous, and neutral culture model for the case of three alternatives, we obtain precise theoretical values for the number of voting situations for the plurality rule, the run-off rule, the Kemeny rule, the Borda rule, and the scoring rules in the extreme case. From enumerative combinatorics, we obtain an information utilization index for these rules. The main results are obtained for the case of three alternatives.

This study explores the successful strategies of companies during the 2008-2009 economic crisis. We investigate whether it is reasonable for companies to intensify intangibles when markets fall. This paper aims to find empirical evidence that companies with a clear intangible-intensive profile are likely to outperform those without a strategy. The results established in this study shed some light on the global economic crisis in 2008-2009. More than 1600 European companies were involved in the empirical analysis. The findings of this study demonstrate that companies with a conservative profile in intangibles outperform moderate and innovative ones. Still an innovative profile enables a faster recovery after a crisis

Drugs of abuse implicate both reward learning and homeostatic regulation mechanisms of the brain. Theories of addiction, thus, have mostly depicted this phenomenon as pathology in either habit-based learning system or homeostatic mechanisms. Showing the limits of those accounts, we hypothesize that compulsive drug seeking arises from drugs hijacking a system that integrates homeostatic regulation mechanism with goal-directed action/behavior. Building upon a recently developed homeostatic reinforcement learning theory, we present a computational theory proposing that cocaine reinforces goal-directed drug-seeking due to its rapid homeostatic corrective effect, whereas its chronic use induces slow and long-lasting changes in homeostatic setpoint. Our theory accounts for key behavioral and neurobiological features of addiction, most notably, escalation of cocaine use, drug-primed craving and relapse, and individual differences underlying susceptibility to addiction. The theory also generates unique predictions about the mechanisms of cocaine-intake regulation and about cocaine-primed craving and relapse that are confirmed by new experiments.

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.

We prove that for a Q-Gorenstein degeneration $X$ of del Pezzo surfaces, the number of non-Du Val singularities is at most $\rho(X)+2$. Degenerations with $\rho(X)+2$ and $\rho(X)+1$ non-Du Val points are investigated.

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 Schrödinger 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.
