We prove that if a smooth variety with non-positive canonical class can be embedded into a weighted projective space of dimension~n as a well formed complete intersection and it is not an intersection with a linear cone therein, then the weights of the weighted projective space do not exceed n+1. Based on this bound we classify all smooth Fano complete intersections of dimensions 4 and 5, and compute their invariants.

This study estimates an attendance demand model in a reduced form, with uncertainty as one of the determinants of demand, to test the Uncertainty of Outcome Hypothesis (UOH), using data from the Russian Football Premier League (RFPL). These data fit our requirements for two reasons. First, there are few sellout matches, so demand for tickets in the RFPL is not restricted by stadium capacity. Secondly, there have hitherto been no articles devoted to the study of outcome uncertainty in the RFPL. The results indicate that the UOH does not explain the behavioural pattern of attendees in the RFPL. The dependence between the attendance and uncertainty is found to be U-shaped or even declining. We explain the U-shaped dependence by the visiting team effect; an attendee’s utility in the RFPL depends more on seeing a top team coming to the city than on the uncertainty of the outcome of the match.

The paper contributes to explain an unexplored competition that is the Brazilian State Championships. How it is organized and the financial features of three championships are described. The aim of the paper is to discover if the presence of "Brand-teams" in a competition increases the income of all participating teams and if the type of championship conditions the effect of Brand Team on revenues of all teams. As the present study aims to be a pioneer in economic research on Brazilian State Championships, it has an exploratory character. The study uses an equations system to estimate for testing the hypothesis. The estimation method is 3SLS to delete the possible endogeneity of the variables. There have been studied 400 matches played by 48 teams from Mineiro, Paulista and Carioca Championships in season 2013. The structure of the Brazilian State Championship, with the participation of brand-teams, creates an income redistribution effect. The features of the visiting team imply an increase in attendance. This effect is moderated by the type of Championship. The Championship structure generates an additional increase of the revenue. They increase according to the phase in which the competition develops. This paper contributes to introduce the Brazilian State Championships. Moreover, it comes to justify the participation of brand-teams in order to help smallest teams to increase their revenues. The paper shows that the organization of some Championships has more beneficial effects than others

In this paper, we study panel data on region-to-region gross migration flows in Russia for 1995-2010. We find that barriers to labor mobility that hindered internal migration in 1990s, have been generally eliminated by the end of 2000s. In 1990s many poor Russian regions were in a poverty trap: potential workers wanted to leave those regions but could not afford to finance the move. In 2000s (especially in late 2000s), these barriers were no longer binding. Overall economic growth and development of financial markets allowed even poorest Russian regions to grow out of the poverty traps. This resulted in convergence in Russian labor market in 2000s; the interregional gaps in incomes, wages and unemployment rates decreased substantially and are now comparable to those in Europe.

Recently proposed Skip-gram model is a powerful method for learning high-dimensional word representations that capture rich semantic relationships between words. However, Skip-gram as well as most prior work on learning word representations does not take into account word ambiguity and maintain only single representation per word. Although a number of Skip-gram modifications were proposed to overcome this limitation and learn multi-prototype word representations, they either require a known number of word meanings or learn them using greedy heuristic approaches. In this paper we propose the Adaptive Skip-gram model which is a nonparametric Bayesian extension of Skip-gram capable to automatically learn the required number of representations for all words at desired semantic resolution. We derive efficient online variational learning algorithm for the model and empirically demonstrate its efficiency on word-sense induction task.

Despite relative normalization of the US-Russia dialogue in early 2013 and their impressive cooperation on Syria and Iran later that year, the relations on the whole remain extremely fragile, volatile and at the same time stagnant. Their traditional agenda, based on arms control, is crumbling; leadership is both countries is not regarding positive US-Russian partnership as central for their vital national interests fulfillment; and the share of contradictions is growing. At best, this deprives the sides of many opportunities to advance their interests through cooperation. At worst, this could spark a new serious crisis by. The author argues that the fundamental problem of the US-Russia relations is their old-fashioned philosophy, centered on strategic deterrence and balancing. This philosophy, the paper claims, in its turn predetermines an agenda of the relations, which poorly reflects the real challenges that US and Russia face in the world of today and tomorrow. The author claims that the new philosophy of the US-Russia relations should be based not on strategic deterrence and strategic balance in a Cold war understanding, but on clear recognition that the sides need each other and need to cooperate in order to deal with real challenges and achieve real opportunities.

Does bridging or bonding social capital matter for redistribution preferences? Existing literature demonstrates causal link between measures of social capital and such preferences but does it mostly for developed countries with good enforcement of formal rules and without a distinction between two completely different types of social capital. We argue that welfare state relies on contributions from an immense number of anonymous citizens, thus attitudes towards strangers, i.e. generalized trust and solidarity should be salient. Using two surveys of about 34,000 and 37,000 Russians we prove this proposition showing the importance of the bridging type but not the bonding one. Instrumenting social capital with education, climate and distance from Moscow we deal with endogeneity concerns. Additionally we claim that connection between social capital and redistribution preferences for less developed countries such as Russia could be similar to developed countries.

We study algebras constructed by quantum Hamiltonian reduction associated with symplectic quotients of symplectic vector spaces, including deformed preprojective algebras, symplectic reflection algebras (rational Cherednik algebras), and quantization of hypertoric varieties introduced by Musson and Van den Bergh. We determine BRST cohomologies associated with these quantum Hamiltonian reductions. To compute these BRST cohomologies, we make use of method of deformation quantization (DQ-algebras) and F-action studied in [Kashiwara-Rouquier], and in [Gordon-Losev].

The classical Ehresmann-Bruhat order describes the possible degenerations of a pair of flags in a finite-dimensional vector space V; or, equivalently, the closure of an orbit of the group GL(V) acting on the direct product of two full flag varieties.  We obtain a similar result for triples consisting of two subspaces and a partial flag in V; this is equivalent to describing the closure of a GL(V)-orbit in the product of two Grassmannians and one flag variety. We give a rank criterion to check whether such a triple can be degenerated to another one, and we classify the minimal degenerations. Our methods involve only elementary linear algebra and combinatorics of graphs (originating in Auslander-Reiten quivers).

We study hiring decisions made by competing universities in a dynamic framework, focusing on the structure of university finance. Universities with annual state-approved financing underinvest in high-quality faculty, while universities that receive a significant part of their annual income from returns on endowments hire fewer but better faculty and provide long-term contracts. If university financing is linked to the number of students, there is additional pressure to hire low-quality short-term staff. An increase in the university’s budget might force the university to switch its priorities from ‘research’ to ‘teaching’ in equilibrium. We employ our model to discuss the necessity for state-financed endowments, and investigate the political economics of competition between universities, path-dependence in the development of the university system, and higher-education reform in emerging market economies.

Current paper brings into consideration the issue of building and developing customer relations in emerging Russian market. Usually multinational companies enter Russian market and try to apply here their business solutions developed in mature markets. Many researchers argue that emerging markets require customer education rather than customer orientation. We develop a complex model of customer orientation and relationship development and test it on the Russian subsidiaries of Finnish construction companies. Qualitative study based on in-depth interviews with middle- and top-managers suggests that processes of customer relations differ dramatically from those established in European market.

Scholars associate bureaucratic quality with economic development. One particularly important component of a well-functioning bureaucracy is meritocratic promotion. This paper explores the conditions under which politicians will appoint high-level bureaucrats on the basis of economic performance. We argue that two key features of democracy—electoral competition and media freedom—  increase  the incidence of performance-based appointments among high-level bureaucrats. We test these claims using original data on turnover among 3762 vice governors in Russia’s 89 regions between 2001 and 2011. We also find that levels of bureaucratic turnover depend on the characteristics of the principal making those appointments.

In the modern globalized world new actors, in particular business, exert increasing influence on the international decision-making processes. The business is generally important and influential actor in the regional governance promoting the group`s common interests. The article aims to test this hypothesis drawing on the findings from study of the APEC Business Advisory Council (ABAC). The author analyses the Asia-Pacific business priorities promoted by the ABAC, actions implemented to make other regional actors acting in line with these priorities and ABAC achievements in that process. The official ABAC and APEC documents constituted the evidence base for the analysis. The research methods used in the article include qualitative content analysis and comparative historical analysis. The author comes to conclusion that business is an influential actor in the Asia-Pacific regional governance due to its capability to promote business priorities implementation at the state level.

The paper presents the Business Climate Indicator (BCI) in the Russian manufacturing including the medium and high-tech (MHT) manufacturing industries. The authors explain the feasibility of a new alternative measure that summarizes common information of business tendency surveys cleared up of specific fluctuations in individual variables, and give arguments to prove its effectiveness. The resulting BCI reflects the quantitative changes in manufacturing growth more accurately and with a lead compared to the traditional confidence indicator. Identification of the BCI cyclic profile and its visualization through a tracer demonstrate all significant waves of manufacturers’ optimism and pessimism for the period from January 2005 to January 2019. To construct BCI-MHT, the units of observation and the input information are divided into three groups according to the technological level of industries. The dynamics of BCI-MHT is close to those of BCI; however, during the protracted recession in 2016-2018, the sentiments of manufacturers of medium- and high-tech products were less pessimistic compared with the sentiments of all manufacturers.

The author analyzes the different forms of relationships between businesses and bodies of state power in Russia: private and public partnership, the delegation of public powers and property, self-regulation, the transfer of government authority to the private organizations, self-regulation, and how public power is influenced including by specialists. The experience of foreign countries and the legal view on the social responsibility of business are provided. The political-legal traditions of the relationships between private organizations and bodies of state power are analyzed. This has predetermined the current legislation.  The informal and relatively new mechanisms of protection of the rights of businesses are described.

The working paper is based on research findings concerning the functioning of 35 Russian technology parks in 2013 – the first half of 2015. The analysis of the performance of these technology parks has been carried out on the basis of the CANVAS framework, proposed by Osterwalder and Pine in 2010. The research was conducted in the domain of 9 key blocks business model of technology parks, including infrastructure and services provided, companies’ residents, cooperation with partners, including regional and federal authorities, scientific and education institutions, financial and economic indicators of technoparks and key performance indicators used. On the basis of empirical data 7 business models of functioning of Russian technology parks were revealed, including IT-park, university park, 2 types of facilitators of innovation processes in a region and 3 types of entrepreneurial technoparks. The classification allows differentiating the nature and level of support of technology parks as objects of innovation infrastructure. Detailed profile of business models reveals the competitive advantages and weaknesses of technoparks, as well as mechanisms to improve the efficiency of these objects of innovation infrastructure.

This paper explores business transactions in the context of the principle of legality. It will be argued that Article 168 of the Russian Civil Code, as a meta-rule, contains three types of rules: 1) rules dealing with the priority of special rule and exceptions (exclusive rules); 2) rules dealing with the interpretation of general, special and exclusive rules as well as with the requirements of statutes or other legal acts violated by a transaction and established outside Article 168 of the Civil Code; 3) rules dealing with the admissibility of special rule and exceptions, as well as with the conditions of admissibility of these rules. With regard to the first group of the rules, the legislature and commercial courts consider Article 168 of the Civil Code a common base with respect to other grounds in the Civil Code and in certain other statutes for declaring transactions invalid. According to the second group of rules, the subject-matter (object) of legal interpretation consists of two elements: а) the text of Article 168 of the Civil Code; and b) the texts of legal acts, described by the generic term “statute or other legal act.” Article 168 of the Civil Code provides instructions not only for rules as objects of application of the article, but also for the methods of interpreting violated requirements. The rules of admissibility for special rule and exceptions, as well as the conditions of admissibility for these standards, are aimed at the numerous cases in which the legislature, in the Civil Code or in other legal acts, expressly establishes nullity (voidness), voidability and other legal consequences for illegal transactions. The paper also answers questions regarding the impact of recent amendments to the Russian Civil Code on using rules for business transaction invalidity in commercial courts.
