This paper is aimed at exploring the rhetorical conventions of political polemics in 19th century Russia. We will compare two texts published in the 1830s – a classic “First Philosophical Letter” by Petr Chaadaev and a less known reply to it written by young Andrej Krayevsky – “Thoughts on Russia”. First we plan to focus on their stated ideas, and then to consider the political language of the opponents. As we will see, if their ideas were completely different, Chaadaev and Krayevsky shared the same political idiom – the language of official national ideology. We will try to demonstrate that it was possible to use the language of the official ideology not only to establish that ideology but paradoxically also to start an open debate with it.

B. Totaro showed \cite{totaro} that the rational cohomology of configuration spaces of smooth complex projective varieties is isomorphic as an algebra to the $E_\infty$ term of the Leray spectral sequence corresponding to the open embedding of the configuration space into the Cartesian power. In this note we show that the isomorphism can be chosen to be compatible with the mixed Hodge structures. In particular, we prove that the mixed Hodge structures on the configuration spaces of smooth complex projective varieties are direct sums of pure Hodge structures.

In arXiv:1807.09038 we formulated a conjecture describing the derived category D-mod(Gr_GL(n)) of (all) D-modules on the affine Grassmannian of the group GL(n) as the category of ind-coherent sheaves on a certain stack (it is explained in loc. cit. that this conjecture "follows" naturally from some heuristic arguments involving 3-dimensional quantum field theory). In this paper we prove a weaker version of this conjecture for the case n=2.

Motivated by dichotomous scholarly results on the conflict-communication nexus, I compare the predictions of two competing theories of urban conflict based on coordination and contagion. I exploit a quasi-experimental intervention in the Syrian nation-wide communications in November 2012 along with a geolocated dataset of daily conflict locations (n= 627) in Damascus to build a panel (n= 275 days x 252 spatial units = 69,300), to show that disruption of communications coincided with an unprecedented increase in the geographic dispersion of conflict. Furthermore, while compared to pro-regime atrocities rebel activity was more spread in space and time, lack of coordination meant more spatiotemporal clustering: a combination of global dispersion and local clustering defined the insurgency. On average, one additional prior incident in the spatiotemporal vicinity translated to 25% higher rates of recurrence. In addition to detecting significant spatiotemporal spillover of violence, I show that the contagion was effectively activated during the blackout.

Market discipline is usually studied in the retail or the corporate deposit markets, while the interbank loan market is disregarded. Banks' abilities to exert market discipline are taken for granted, as they are expected to have the expertise to assess correctly the riskiness of other banks. However, the “crises of trust” (as one in 2004 in Russia) create some doubts as to whether efficient peer monitoring and peer discipline exist: the interbank loan market may be frozen in response to external information which is unrelated to the banks’ current reliability. This seems to be one of the reasons for the interbank loan markets being extremely fragile during periods of financial instability, undermining the smooth functioning of the whole banking system, as banks are tightly interconnected. We provide some evidence for market discipline in the Russian interbank market. We show that the only disciplinary mechanism that functions is a price-based one: more reliable banks enjoy lower interest rates. The quantitative discipline functions only for the largest borrowers. In general, decisions on credit limits are based not on changes in another bank’s riskiness but on other information like reputation, soft information or public announcements that may be even unrelated to a particular bank.

In the times of Soviet Union books were a luxury good. This paper examines whether books are still a luxury good in Russia. For this purpose data from one of the Russian book retail chains is used to empirically estimate a general book demand and separate demand models for genres. We focus on estimating income elasticity. For this reason we construct a covariate on the basis of monthly wages of working individuals that reveals consumer income. Moreover, this paper is one of the few which addresses in detail the influence of books content quality on book demand. The main result is that books on average are not luxury goods anymore in Russia. However two genres: foreign prose and poetry are exceptions and can be called luxury goods. We also conclude that quality control covariates (book rating and number of people who rated the book) are important determinants of book demand as they influence significantly the general book demand and the demand models for different genres as well.

This paper constructs a DSGE model for an economy with commodity exports. We estimate the model on Russian data, making a special focus on quantitative effects of commodity price dynamics. There is a widespread belief that economic activity in Russia crucially depends on oil prices, but quantitative estimates are scarce. We estimate an oil price effect on the Russian economy in the general equilibrium framework. Our framework is similar to those of Kollmann(2001) and Dam and Linaa (2005), but we extend their models by explicitly accounting for oil revenues. In addition to standard supply, demand, cost-push, and monetary policy shocks, we include the shock of commodity export revenues, which are supposed to be like a windfall. The main objective of the paper is to identify the contribution of structural shocks to business cycle fluctuations in the Russian economy. We estimate the parameters and stochastic processes that govern ten structural shocks using Bayesian techniques. The model yields plausible estimates, and the impulse response functions are in line with empirical evidence. We found that despite a strong impact on GDP from commodity export shocks, business cycles in Russia are mostly domestically based

Democracy has not always accompanied market economy. But in modern societies, economic and political freedoms are increasingly interconnected. Democracy and market economy can support each other. This is particularly true in post-communist economies of Central and Eastern Europe and the former Soviet Union. Thus, authoritarian tendencies observed in these and other regions can negatively affect quality of economic policy and governance.

The temporal dynamic characteristics of mood play an important role in various aspects of our lives including our psychological health and well-being. It is assumed that the individuals with high emotional intelligence (EI) are characterized by more positive and stable moods. However, most studies analyze how EI is related to emotional traits or momentary assessments of mood; there are almost no findings on EI relationships with mood dynamics. The present study fills this gap. Two research questions were asked. How mood dynamics characteristics are related to each other and to what extent are they independent? Which aspects of EI are related to particular characteristics of mood dynamics? Method. To collect data on mood dynamics, an experience sampling procedure was implemented. Twenty-six female participants reported their mood for two weeks, three times a day, using the EmoS-18 questionnaire. Their emotional intelligence was measured with the EmIn questionnaire. Mean mood scores calculated across all measurement points were regarded as static characteristics showing a mood background typical for the participant. Also, three dynamic characteristics of mood were calculated, namely variability, instability, and inertia. Results. Mood variability and instability were found to be very closely related to each other, measuring essentially the same construct. Inertia is relatively independent. EI was not related to mean mood scores which contradicts the results of other studies and can be explained by the use of the experience sampling procedure. EI was positively related to the inertia of a positive mood with high arousal and a negative mood with low arousal. In addition, a negative relationship between EI and the instability of tension was found. Most of the correlations were low. Further studies with higher statistical power are needed for more decisive conclusions. However, the results show that experience sampling provides new important insights on the role of EI in mood

This study analyzes the phenomenology of socio-psychological capital viewed as a resource for psychological relations which constitutes the basis for the formation of social capital. A cross-cultural analysis of the impact of value orientations on socio-psychological capital has been performed. Based on a sample of 3 ethnic groups (Russians, n = 103; Chechens, n = 100; Ingush, n = 109), it has been demonstrated that although the impact of individual values on socio-psychological capital obeys logic, it may be culture-specific. Values of Self-Transcendence (Benevolence and Universalism) have a positive impact on the socio-psychological capital of a multicultural society, whereas values of Self-Enhancement influence it negatively. Openness to Change values positively influence civic identity but have a negative effect on perceived social capital. Conservation values positively affect the civic (Russian) identity of the representatives of the Ingush ethnic group.

We show that a direct limit of surjections of (weak) Golod--Shafarevich algebras is a weak Golod--Shafarevich algebra as well. This holds both for graded and for filtered algebras provided that the filtrations are induced by the filtration of the first entry of the sequence. It follows that the limit is an algebra of exponential growth. An example shows that the assumptions of this theorem cannot be directly weakened.

The paper starts with discussing institutional framework for public sector wage setting in Russia. Given that individual choice of the sector is endogenous to wages, the authors recommend alternative econometric techniques for the public-private wage gap estimation. Applying switching regression that allows correcting for non-random sector selection, the paper provides wage gap estimates for various demographic, occupational, and territorial population subgroups. As it is shown, there is significant cross-group variation in the wage gap. The paper concludes that to eliminate the negative gap wages in the public sector should be linked to the private sector wages at the regional level.

  The paper suggests several ways to rediscover the legacy of early modern and classical natural law of the 18th century in contemporary legal thought through the joint efforts of legal history and legal theory with particular reference to the domain of contract law. Additionally, the paper justifies the revival of the research in the domain of natural law in connection with legal argumentation.

The rim-hook rule for quantum cohomology of the Grassmannian allows one to reduce quantum calculations to classical calculations in the cohomology of the Grassmannian. We use the Abelian/non-Abelian correspondence for cohomology to prove a rim-hook removal rule for the cohomology of quiver flag varieties. Quiver flag varieties are generalisations of type A flag varieties; this result is new even in the flag case. This gives an effective way of computing products in their cohomology, reducing computations to that in the cohomology ring of the Grassmannian. We then prove a quantum rim-hook rule for Fano quiver flag varieties (including type A flag varieties). As a corollary, we see that the Gu--Sharpe mirror to a Fano quiver flag variety computes its quantum cohomology.

Our main object of study is a 3−valent graph with a vector function on its edges. The function assignes to an edge a pair of 2−adic integer numbers and satisfies additional condition: the sum of its values on three edges, terminating in the same vertex, is equal to 0. For each vertex of the graph three vectors corresponding to these edges generate a lattice over the ring of 2−adic integers. In this paper we study the restrictions, imposed on these lattices by the combinatorics of the graph. As an application we obtain the following fact: a rational balanced polygon cannot be cut into an odd number of triangles of equal areas. First result of this type was obtained by Paul Monsky in 1970. He proved that a square cannot be cut into an odd number of triangles of equal areas. In 2000 Sherman Stein conjectured that the same holds for any balanced polygon. We prove this conjecture in the case, when coordinates of all vertices of the cut are rational numbers.

Investors are being encouraged after the global crisis to reduce their dependence on the largest credit rating agencies for risk assessments of companies and securities. Comparing risk assessments from different sources rapidly becomes non-trivial when more than three credit rating agencies are involved. We propose a method for comparing rating scales, and hence constructing correspondence diagrams and tables, thereby treating the rating scales used by different agencies as objects of study. Scales are compared by looking at sets of ratings assigned to similar entities (in this case banks) with the assumption that the risk being measured by each credit rating agency is the same for a given rated entity at a given point in time. Two ratings assigned by two credit rating agencies may differ for two reasons: the two agencies have different opinions about the relative positioning of the rated entity (e.g., issuer or security) with respect to the universe of other rated entities; both agencies position the rated entity with respect to the universe of other rated entities in the same way, but they use different symbols to represent this position. Type 1 differences should disappear when a large number of ratings are considered. The existence of type 2 differences will require a mapping from one rating scale to another. Studying international bank ratings for a five-year period shows that there are type 2 differences for the largest credit rating agencies. A mechanism for constructing mappings between scales could lead to more competition with new credit rating agencies.

Artificial intelligence is having a transformative effect on business world. Among others, legal services industry is susceptible to these transformations, but being a part of the legal system, it adopts novelties more slowly than other service-based industries. The issue of AI acceptance for legal services is widely discussed in Russia. Opportunities and threats of AI implementation are the subjects of academic research, business enquires, experts' assessments, and professional community discussions. Still, all those pieces of evidence are biased by the objectives of specific research and methodology used, mostly have no or little empirical data to ground conclusions on. The absence of empirical evidence on the state-of-theart of AI in legal services and users’ expectations on AI implementation hinders further research in various topics – from legal firms’ management and legal innovations to the lawyering process and access to justice. This paper confirms expert opinions regarding AI technologies and their implementations for legal services, suggesting the cooperation of lawyer and AI in legal service rendering rather than competition. Russian lawyers appear to have the experience of using very advanced AI solutions, including those that are unavailable directly on the Russian market. The expectations of lawyers as users of AI technologies could be described as uncertain, which means that further extension of AI implementation is still a disputable issue.
