Tretyakov S. V. Высшая школа экономики, 2014. No. 1.
The main idea of this paper is that some sort of legal theory dealing with the law’s social impact is an indispensable element of the legal profession in the time of late modernity. Can legal theory provide an adequate understanding of the social context of the application of law, relying solely on internal resources? If not, which interdisiplinary discourse is the best and why?

One major repercussion of the Russian-Georgian war of August 2008 was a significant increase in the EU‟s presence in Georgia. With the launch of the Eastern Partnership in May 2009, the deployment of an EU monitoring mis-sion in Georgia and the EU‟s participation in the Geneva talks, EU-Georgian relations appear to have entered a new stage. The war has also affected Geor-gia‟s foreign policy priorities with the EU acquiring a new significance at the same time as the prospect of NATO integration has become more uncertain. This paper reviews the evolution of EU-Georgian relations since Georgia‟s independence and asks whether the post-war context has brought a change in the nature of these relations. First, it analyzes the relations before the Rose Revolution and the nature of the EU‟s engagement in Georgia. Second, it ex-amines the changes after the revolution, focusing in particular on the diverg-ing expectations of the EU and Georgia. Finally, it asks whether the post-war context has brought more convergence between the two actors.

Economic growth in Russia in the first decade of this century almost doubled the country’s GDP but was accompanied by substantial reallocation of labor to the unregulated sector while formal employment was on gradual decline. The paper overviews evolution of the Russian labour market during the period of 2000-10 and discusses most general implications of informality to employment and earnings as well as the associated political economy challenges and consequences.

One of the most prominent in analytic philosophy is the so-called "Fregean Axiom", according to which the reference of a sentence is a truth-value. In contrast to this referential semantics, a use-based formal semantics will be constructed in which the logical value of a sentence is not its putative referent but the information it conveys. Let us call "Question Answer Semantics" (thereafter: QAS) the corresponding formal semantics: a non-Fregean many-valued logic, where the meaning of any sentence is an ordered n-tuple of yes-no answers to corresponding questions. A sample of philosophical problems will be approached in order to justify the relevance of QAS. These include: (1) illocutionary forces, and the logical analysis of speech-acts; (2) the variety of logical negations, and their characterization in terms of restricted ranges of logical values; (3) change in meaning, and ute use of dynamic oppositions for belief sets.

I study a career concerns model in which the principal obtains information about the agent’s performance from an intermediary (evaluator), whose interests diverge from those of the principal. I show that, while the evaluator’s bias leads to ex-post suboptimal decisions regarding the agent (e.g., inefficient promotion or dismissal), it incentivizes the agent to exert more effort. As a result, generally, a non-zero bias is optimal. The optimal bias is “anti-agent” (“pro-agent”) when the agent is of high value (low value) for the principal from the ex-ante perspective. The magnitude of the optimal bias is increasing in the strength of the agent’s career concerns and decreasing in the degree of uncertainty about the agent’s ability. I also obtain that delegating decision rights to the evaluator may be preferred to communication when a sufficiently large bias is required to create incentives. I discuss applications of my results to promotion policies in organizations, evaluation of government programs and evaluation of CEOs by boards of directors.

The paper discloses a new approach to emerging technologies identification, which strongly relies on capacity of big data analysis, namely text mining augmented by syntactic analysis techniques. It discusses the wide context of the task of identifying emerging technologies in a systemic and timely manner, including its place in the methodology of foresight and future-oriented technology analysis, its use in horizon scanning exercises, as well as its relation to the field of technology landscape mapping and tech mining. The concepts of technology, emerging technology, disruptive technology and other related terms are assessed from the semantic point of view. Existing approaches to technology identification and technology landscape mapping (in wide sense, including entity linking and ontology-building for the purposes of effective STI policy) are discussed, and shortcomings of currently available studies on emerging technologies in agriculture and food sector (A&F) are analyzed. The opportunities of the new big-data-augmented methodology are shown in comparison to existing results, both globally and in Russia. As one of the practical results of the study, the integrated ontology of currently emerging technologies in A&F sector is introduced. The directions and possible criteria of further enhancement and refinement of proposed methodology are contemplated, with special attention to use of bigger volumes of data, machine learning and ontology-mining / entity linking techniques for the maximum possible automation of the analytical work in the discussed field. The practical implication of the new approach in terms of its effectiveness and efficiency for evidence-based STI policy and corporate strategic planning are shortly summed up as well.

  We study which Big Five personality traits are associated with academic performance among a sample of Russian university students using results from the Unified State Examination (for university admissions) and their current grade point averages as measures of academic performance. We find that Introversion, Agreeableness, Neuroticism, and Openness to experience have observable ties to academic performance. Those results partially confirm existing international studies, but our findings are notable for the relative unimportance of  conscientiousness for success in our Russian sample. We suggest that cross-cultural differences  in educational environment may explain why this trait seems less obviously important in the analysis.

We prove that a finite group acting by birational automorphisms of a non-trivial Severi-Brauer surface over a field of characteristic zero contains a normal abelian subgroup of index at most 3. Also, we find an explicit bound for orders of such finite groups in the case when the base field contains all roots of 1.

We study birational projective models of M_2,2 obtained from the moduli space of curves with nonspecial divisors. We describe geometrically which singular curves appear in these models and show that one of them is obtained by blowing down the Weierstrass divisor in the moduli stack of Z-stable curves \bar{M}_2,2(Z) defined by Smyth. As a corollary, we prove projectivity of the coarse moduli space \bar{M}_2,2(Z).

We study the complexity of birational self-maps of a projective threefold X by looking at the birational type of surfaces contracted. These surfaces are birational to the product of the projective line with a smooth projective curve. We prove that the genus of the curves occuring is unbounded if and only if X is birational to a conic bundle or a fibration into cubic surfaces. Similarly, we prove that the gonality of the curves is unbounded if and only if X is birational to a conic bundle.

According to the classical theorem, every irreducible algebraic variety endowed with a nontrivial rational action of a connected linear algebraic group is birationally isomorphic to a product of another algebraic variety and the s-dimensional projectice space with positive s. We show that the classical proof of this theorem actually works only in characteristic 0 and we give a characteristic free proof of it. To this end we prove and use a characterization of connected linear algebraic groups G with the property that every rational action of G on an irreducible algebraic variety is birationally equivalent to a regular action of G on an affine algebraic variety.

The paper considers the changes in major proximate determinants of fertility in Russia within the framework of demographic transition theory and Bongaarts approach to fertility analysis. After World War II Russian fertility became fully controlled process. The complex interplay of abortion and contraception during the Soviet period resulted in a very high abortion level. Russian government has almost never supported and promoted family planning as alternative to abortion. However couple's preferences of small offspring appeared more powerful than the will of authorities. Current trends show that albeit lack of governmental support the society itself is evolving towards more humanistic and effective birth control. Estimates made upon recent surveys' data confirm the validity of official statistics and thus the reality of favorable trend of abortion decline.

The main goal of public procurement reform in Russia, initiated in 2005, was to prevent corrupt deals between suppliers and procurers. That is why the public procurement law favors formal mechanisms to govern most of the stages of procurement: the procurer is not allowed to take into account the reputation of the supplier when he announces calls for bids and selects the supplier, and he is prescribed to use the legal system (courts) if he is not satisfied with the contract performance. Since the efficiency of formal institutions is not very high, these mechanisms are complemented by a “formalized informal instrument” - blacklisting opportunistic suppliers, which is believed to substitute for reputation mechanisms when formal mechanisms are weak. In this paper, we show how and why the institutional environment in Russia makes the blacklisting of opportunistic suppliers irrelevant. We explore how the percentage of contract breaches out of the total number of signed contracts is related to corruption and transparency measures for Russian regions. We also argue that such factors as measurement costs, verification costs, length of contracts and lawsuit amounts influence the probability of winning a legal action for a contract breach.

This paper provides new evidence on the structure, dynamics and performance effects of corporate boards in publicly traded companies in Russia. It takes advantage of a new and unique longitudinal dataset of virtually all Russian companies whose shares were traded in the RTS/MICEX/MOEX over 1998-2014. The analysis highlights a number of strong trends in the evolution of boards of directors, such as the declining participation of insider directors and the increasing participation of foreign and female directors. It also shows that board characteristics are linked to company performance (the market-to-book ratio, Tobin’s Q, ROE and ROA), suggesting that boards of directors play a non-trivial role in corporate governance in Russia. Testing for structural breaks in the relationship between board composition and firm performance provides some evidence of the changing role of corporate boards over time.

We give a simple construction of the correspondence between square-zero extensions R′ of a ring R by an R-bimodule M and second MacLane cohomology classes of R with coefficients in M (the simplest non-trivial case of the construction is R=M=Z/p, R′=Z/p2, thus the Bokstein homomorphism of the title). Following Jibladze and Pirashvili, we treat MacLane cohomology as cohomology of non-additive endofunctors of the category of projective R-modules. We explain how to describe liftings of R-modules and complexes of R-modules to R′ in terms of data purely over R. We show that if R is commutative, then commutative square-zero extensions R′ correspond to multiplicative extensions of endofunctors. We then explore in detail one particular multiplicative non-additive endofunctor constructed from cyclic powers of a module V over a commutative ring R annihilated by a prime p. In this case, R′ is the second Witt vectors ring W2(R) considered as a square-zero extension of R by the Frobenius twist R(1).

This paper estimates the effect of economic shocks that affect families with young children on children’s health, educational and behavioral outcomes in adolescence.  Transition period in Russia provides a natural experiment setting for estimating this effect.  During the economic turmoil of early transition many people lost their jobs, experienced salary declines or occupational downgrading. These individual labor market shocks were mainly caused by the structural changes in the economy. Analyzing household survey data from Russia I find that children who were under the age of five and whose parents were negatively affected during the early transition have poorer health in adolescence and are less likely to have completed high school. For the comparison group  –  children who were at the school age during the early transition  –  there is an effect on educational outcomes and risky behaviors but not on health. Absence of a father in a family during the early transition years has a negative health effect only for the younger age group. I also find differential effects for boys and girls, by mother and father.

We classify compact complex surfaces whose groups of bimeromorphic selfmaps have bounded finite subgroups. We also prove that the stabilizer of a point in the automorphism group of a compact complex surface of zero Kodaira dimension, as well as the stabilizer of a point in the automorphism group of an arbitrary compact Kaehler manifold of non-negative Kodaira dimension, always has bounded finite subgroups.
