Gimpelson V. E., Kapeliushnikov R. Discussion Paper. IZA DP. Institute for the Study of Labor, 2017. No. 11126.
This paper deals with age and educational dimensions of the labour supply in Russia and explores two time periods: from 2000 to 2015 (retrospective), and the next 15 years (prospective). For our analysis we exploit the micro-census (2015) data and all LFS waves covering the retrospective period. Combining demographic projections with expected employment rates and data on educational achievement we forecast the employment composition up to 2030. If recent past changes in both age and education have contributed to economic growth, their effect is likely to be negative in the next 15 years. These two dimensions are directly associated with such challenges as ageing and over-education of the labour force. Russia is not unique here, but it is more exposed to both dimensions than are many other countries due to its demographic and educational developments. The paper concludes with several tentative policies that could ease, although not cure, the problem.

A comparative analysis of the age impact on happiness in Russia and European countries was conducted. The European Social Survey data in 2012 for 29 countries were used. On the basis of an ordered logistic regression, a U-shape relationship between age and happiness was obtained for some of the analysed countries. By using cluster analysis, the countries were divided into 3 groups, in which the age effect varies greatly. In the counties of group 1 (for example, Iceland and Norway) happiness did not change at any age or increase smoothly in old age. Group 2 (Germany and France) had a clear U-shaped age-happiness form. Russia and some counties of former Soviet Union: Ukraine, Lithuania and Estonia were analysed in group 3, where the level of happiness decreased significantly in old age (over 60). In some countries (Belgium, Switzerland, Cyprus, Denmark, Finland, Israel, Italy, Sweden) all people were happy, regardless of age and the assumption of age-happiness U-shape relation was not found. The socio-economic determinants of happiness were also analysed in different age groups. Income satisfaction and subjective health were the more significant characteristics.

We propose a model in which an entrepreneur, seeking outside fi nancing, sells a large equity share to an outside blockholder in order to signal his low propensity to extract private benefi ts. A conventional theoretical rationale for the presence of an outside block holder is mitigation of the agency problem via some type of monitoring or intervention. Our model provides a novel insight: outside blockholders may be attracted by fi rms with low, rather than high, agency problems. Our result yields a new implication for the interpretation of an often documented positive relationship between outside ownership concentration in a fi rm and its market valuation: such relationship may be driven by “sorting” rather than by a direct effect of blockholder monitoring. In fact, we show that the positive correlation may arise even if the blockholder derives private benefi ts and has no positive impact on the value of small shares. Finally, we argue that our analysis may help explain why the market reacts more favorably to private placements of equity as opposed to public issues.

Although conflict representation in media has been widely studied, few attempts have been made to perform large-scale comparisons of agendas in the media of conflicting parties, especially for armed country-level confrontations. In this paper, we introduce quantitative evidence of agenda divergence between the media of conflicting parties in the course of the Ukrainian crisis 2013-2014. Using 45,000 messages from the online newsfeeds of a Russian and a Ukrainian TV channels, we perform topic modelling coupled with qualitative analysis to reveal crisis-related topics, assess their salience and map evolution of attention of both channels to each of those topics. We find that the two channels produce fundamentally different agenda sequences: in particular, while the Russian channel pays little attention to confrontation between the Ukrainian government and the opposition before the regime change, the Ukrainian channel is less inclined to cover armed violence in East Ukraine and refugees after the regime change.

The purpose of this study is to test the agenda-setting theory, according to which the media has a significant impact on what people consider to be important events. We compare the results of the Levada Center surveys on the most memorable events of the month with the number of publications on these issues in the press. We focused on the period from January 2014 to December 2016. A total of 884 events were analyzed in the article. The results of the study confirm the impact of discussions in the media on people's attention to the problem. The results also show that the discussions in the media one week before the date of polling are more important than the issues covered over the entire month. People better remember those events which took place shortly before the polling, as well as the events the discussion of which intensified during this period. It is also important to note the role of regional publications in the sensitization of the public to various issues. The issues covered by the national newspapers and news agencies, but ignored by the regional press, are much worse remembered by the population. The results of the study are controlled for background of the discussion: the presence of important events in each relevant month, which monopolized the public attention, is taken into account.

We consider NP-hard multi{machine scheduling problems with the criterion of minimizing the maximum penalty, e.g. maximum lateness. For such problems, we introduce a metric which delivers an upper bound on the absolute error of the objective function value. Taking the given in- stance of some problem and using the introduced metric, we determine the nearest instance for which a polynomial or pseudo-polynomial algorithm is known. For this determined instance, we construct a schedule which is then applied to the original instance. It is shown how this approach is applied to di_erent scheduling problems.

We examine a new general class of hazard rate models for survival data, containing a parametric and a nonparametric component. Both can be a mix of a time effect and (possibly time-dependent) marker or covariate effects. A number of well-known models are special cases. In a counting process framework, a general profile likelihood estimator is developed and the parametric component of the model is shown to be asymptotically normal and efficient. The analysis improves on earlier results for special cases. Finite sample properties are investigated in simulations. The estimator is shown to work well under realistic empirical conditions. The estimator is applied to investigate the long-run relationship between birth weight and later-life mortality using data from the Uppsala Birth Cohort Study of individuals born in 1915-1929. The results suggest a relationship that is difficult to capture with simple parametric specifications. Moreover, its shape at higher birth weights differs across gender.

The problem of autonomous navigation is one of the basic problems for robotics. Although, in general, it may be challenging when an autonomous vehicle is placed into partially observable domain. In this paper we consider simplistic environment model and introduce a navigation algorithm based on Learning Classifier System.

In this paper we consider a graphical realization of dynamic programming. The concept is discussed on the partition and knapsack problems. In contrast to dynamic programming, the new algorithm can also treat problems with non-integer data without necessary transformations of the corresponding problem. We compare the proposed method with existing algorithms for these problems on small-size instances of the partition problem with $n \le 10$ numbers. For almost all instances, the new algorithm considers on average substantially less "stages" than the dynamic programming algorithm.

The paper suggests a classification of Russian commercial banks for the purposes of empirical analysis. While most of the literature on comparative bank performance in transition identifies three broad categories of banks (state, domestic private and foreign), in the Russian case it may be proper to consider separately the core state-controlled banks that jointly account for over 40 percent of total assets. Among all foreign-controlled banks we identify foreign subsidiary banks whose parents are financial institutions and whose core business in Russia is commercial banking. This paper complements previous papers on Russian bank data (Schoors, 2000; Karas and Schoors, 2005; 2010; Vernikov, 2007; 2009; 2012; 2014). We attach a list of state-controlled banks and foreign subsidiary banks that have been active during the period up to 2014.

The Acts of Andrew and Matthias contains in a not evident form a feast cycle, which could represent a liturgical practice of the 4th c.-community where the Acts were written. Three days of Andrew’s torments could be linked with Holy Wednesday, Holy Thursday and Good Friday. They are preceded by 27 or 28 days, i.e., 4 weeks of grief and some kind of fast. Andrew’s torments are followed by his miraculous healing that could be compared to Resurrection and Easter. After it Andrew is most likely to have baptized the cannibals ; it reminds one of an ancient tradition of single baptism on Holy Saturday. Finally Andrew has to remain in the city for seven more days ; together with the day of baptism they form those eight days for neophytes’ confirmation before ablutions and at the same time complete the Octave of Easter, that ends with taking baptismal cloths off the neophytes. Andrew’s departure could also be compared with Ascension that was linked with While Sunday. A liturgical circle could be seen on a lower level as well in ch. 2–3 : Matthias’ prayer – Christ’s admonition with citation of the Gospel – «peace be with you» – Matthias’ exclamation – singing of Psalms.

The aim of this study is to examine the validity and reliability of the Leach et al. model of in-group identification in 2 studies of Russian samples. In study 1, the confirmatory factor analysis revealed that the hierarchical model of in-group identification, which included the second-order factors of self-definition (individual self-stereotyping, and in-group homogeneity) and self-investment (satisfaction, solidarity, and centrality) fitted the data well for all four group identities (ethnic, religious, university, and gender) and was a better fit than the alternative models. In study 2, we examined the construct validity and reliability of the Russian version of in-group identification measure. Results show that these measure have adequate psychometric properties. In short, our results show that the Leach et al. model is reproduced in Russian culture. The Russian version of this measure can be used in future in-group research conducted using Russian-language samples.

The gamma kernels are a family of projection kernels K(z,z′)=K(z,z′)(x,y) on a doubly infinite 1-dimensional lattice. They are expressed through Euler's gamma function and depend on two continuous parameters z,z′. The gamma kernels initially arose from a model of random partitions via a limit transition. On the other hand, these kernels are closely related to unitarizable representations of the Lie algebra 𝔰𝔲(1,1). Every gamma kernel K(z,z′) serves as a correlation kernel for a determinantal measure M(z,z′), which lives on the space of infinite point configurations on the lattice. We examine chains of kernels of the form …,K(z−1,z′−1),K(z,z′),K(z+1,z′+1),…, and establish the following hierarchical relations inside any such chain: Given (z,z′), the kernel K(z,z′) is a one-dimensional perturbation of (a twisting of) the kernel K(z+1,z′+1), and the one-point Palm distributions for the measure M(z,z′) are absolutely continuous with respect to M(z+1,z′+1). We also explicitly compute the corresponding Radon-Nikodým derivatives and show that they are given by certain normalized multiplicative functionals.

In this paper we develop a joint non-parametric approach to the problem of the decomposition of bond yields and CDS spreads. The proposed approach is essentially an infinite-dimensional modification of the Heath-Jarrow-Morton framework and is general enough to capture even very non-trivial shapes of the yield and hazard-rate curves. The approach allows us to jointly estimate entire term structures of yields, hazard rates, and liquidity premiums, no matter what shapes they take. We apply the developed methodology to data on major Eurozone sovereign borrowers and consider the most recent period of the Eurozone debt crisis. Our data set includes instruments with maturities from 6 months to 30 years. As a result, we found several interesting interaction effects between those components in terms of term structure. Treating the bond-CDS basis as a measure of the cross-market liquidity spread, we find that cross-market liquidity evolves in a rather non-trivial and pronounced manner. As the credit quality of the reference entity deteriorates, the liquidity of the CDS market dries up, starting from longer terms.

The paper describes the ongoing research project on Ninilchik Russian as a unique variety of the Russian language. We believe it is a remnant of Alaskan Russian – a language that emerged at the end of the 18th century as a result of Russian colonial presence in Alaska and served as a means of communication in Russian America until the end of the Russian period in 1867. By that time Alaskan Russian became the native language for the people of mixed Russian/Native origin residing in various parts of Alaska. Ninilchik was one such place and, due to many factors combined, became a major location where this linguistic variety kept developing and serving as a means of communication, creating and maintaining cultural identity, and holding together the community of brave, persistent, and self-sustained people. Thanks to the people of Ninilchik, Alaskan Russian is still alive in the 21st century. The paper deals with two aspects of this multifaceted linguistic phenomenon. One is a theoretical problem of the “archaeological approach” to the language data which reflects a rather short but diverse history of Alaskan Russian and involves contact studies. Another is the Ninilchik Russian Dictionary project that allows to record both items and concepts, s well as the sociocultural narratives together making up the special story of the linguistic and cultural community

In economic theory, alcohol consumption is considered as an addictive and sometimes irrational behaviour. Such behaviour often leads to undesirable external effects: increasing crime rates, traffic and occupational accidents, fires, and domestic violence. That is why most countries facing high levels of alcohol intake apply special measures to reduce consumption and, as a result, the external effects. Recently, the same measures have also been put in place in Russia, including price rises and time restrictions on retail alcohol sales. This paper investigates the influence of these measures on crime indicators. The empirical study is based on an econometric analysis of panel data from Russian regions, 2003-2015. The results confirm the effectiveness of time restrictions on alcohol sales with regard to juvenile and adult crime. However, the increase of vodka prices due to increasing excise tax reduces juvenile crime but does not influence crime rates among adults.

This paper discusses the problem of the adaptation of a new cultural model by the educated members of the Russian “middle class” in the late 18th century when new social skills and new kinds of the perception of social reality were transmitted to the public through the emotionally very intensive theatre performances. Examining the translation of the drama Poverty and Nobleness of Mind by August von Kozebue and taking into account that the drama was staged at the private theatre of Alexandr Vorontsov, Malinovskii’s patron, in 1799, I suggest that he had some apprehensions about his own noble status which he obtained in a specific way. He seems to face the choice: to act on his feelings as sentimental dramas instructed him and marry a poor but noble girl in 1790s, or wait until Vorontsov’s niece became a wealthy heiress what actually happened in a decade.

Alfred Schütz has paid considerable attention to the position of scientist in the world and particularly to that of social scientist. His analyses make extensive use of phenomenological concepts and contain detailed descriptions of scientific cognitive style in its relation to the everyday life. However, Schütz is surprisingly silent on the motives that could justify quitting the ordinary 'world of working' and entering the scientific attitude. This paper discusses whether the Schütz normative justification for science can be deduced from Husserl's philosophy of science. It is argued that despite the fact that Schütz was in fact considerably influenced by Husserl's system of science suggested in 'Ideas II', the two thinkers diverge radically on the cultural mission and methodology of science. While Husserl advocates the critical method of reduction as the sole way to pursue genuine science, Schütz in fact explores the possibility of building a 'naive science'. He accepts relying on ordinary knowledge in social science and ends up by rejecting the methodology of reduction in general. Schütz's opposition to the idea of science contained in Husserl's phenomenology, together with his neglect of normative grounding of science, suggest that he considered the value of science as laying beyond rational philosophical justification

A projective manifold M is algebraically hyperbolic if there exists a positive constant A such that the degree of any curve of genus g on M is bounded from above by A(g-1). A classical result is that Kobayashi hyperbolicity implies algebraic hyperbolicity. It is known that Kobayashi hyperbolic manifolds have finite automorphism groups. Here we prove that, more generally, algebraically hyperbolic projective manifolds have finite automorphism groups.
