Working paper
Guriev S., Vakulenko E. CEFIR / NES Working Paper. Центр экономических и финансовых исследований и разработок в российской экономической школе, Российская экономическая школа, 2012. No. 180.

In this paper we study convergence among Russian regions. We find that while there was no convergence in 1990s, the situation changed dramatically in 2000s. While interregional GDP per capita gaps still persist, the differentials in incomes and wages decreased substantially. We show that fiscal redistribution did not play a major role in convergence. We therefore try to understand the phenomenon of recent convergence using panel data on the interregional reallocation of capital and labor. We find that capital market in Russian regions is integrated in a sense that local investment does not depend on local savings. We also show that economic growth and financial development has substantially decreased the barriers to labor mobility. We find that 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 development allowed even poorest Russian regions to grow out of the poverty traps. This resulted in convergence in Russian labor market; the interregional gaps in incomes, wages and unemployment rates are now below those in Europe. The results imply that economic growth and development of financial and real estate markets eventually result in interregional convergence.

Pointwise convergence of spherical averages is proved for a measure-preserving action of a Fuchsian group. The proof is based on a new variant of the Bowen-Series symbolic coding for Fuchsian groups that, developing a method introduced by Wroten, simultaneously encodes all possible shortest paths representing a given group element. The resulting coding is self-inverse, giving a reversible Markov chain to which methods previously introduced by the first author for the case of free groups may be applied.

In this paper, we consider projection estimates for L{\'e}vy densities in high-frequency setup. We give a unified treatment for different sets of basis functions and focus on the asymptotic properties of the maximal deviation distribution for these estimates. Our results are based on the idea to reformulate the problems in terms of Gaussian processes of some special type and to further analyze these Gaussian processes. In particular, we construct a sequence of excursion sets, which guarantees the convergence of the maximal deviation distribution to the Gumbel distribution. We show that the rates of convergence presented in previous research on this topic are logarithmic and construct the sequences of accompanying laws with power rates.

Addressing regional disparities is key to unlocking Russia’s potential to achieve stronger gains in growth and equity outcomes as well as to improve its institutional environment. While spatial disparities have been an important policy concern in Russia for a long time, inequalities across its vast territory remain stark. This report explores the current state of regional disparities at the macro and micro-level, updating existing literature to reflect recent trends and providing new insights into household-level drivers of welfare. The report stresses that addressing spatial disparities does not necessary imply “balancing” growth across a geographic territory – but rather focusing on creating opportunities for all people, regardless of where they live.

What factors affect citizens’ willingness to cooperate with the state? We explore this question through a study of citizens’ willingness to report crimes to the police, one of the quintessential forms of cooperation with the state apparatus. We develop a “calculus of cooperation” that high-lights three sets of factors that potentially influence citizens’ incentives to report a crime: benefits of cooperation received only if the crime is solved, benefits of cooperation received regardless of whether the crime is solved, and costs of cooperation. We evaluate the importance of these consid-erations using data from a set of survey experiments conducted in Moscow, Russia in December 2011. We find that citizens’ willingness to cooperate with the police is influenced by the nature and perpetrator of the crime but not by material rewards, appeals to civic duty, or the time required to report a crime. These results suggest skepticism about the ability of governments to easily engineer cooperation with the state.

This paper develops an integrated framework to examine the determinants of industry-science cooperation in the general process of developing innovation. Based on the literature review and using firm-level data on innovation strategies of 805 manufacturing enterprises in Russia we investigate what are the incentives to firms (1) to cooperate with universities and R&D organizations and (2) to choose a particular mode of interaction that ranges from purchasing S&T services to a full scale original R&D aimed at creating new-to-market innovation. We suggest that a broad range of intramural and external determinants, including competition regime, absorptive capacity, technological opportunities, appropriability conditions, public support, as well as barriers to the practical application of R&D results influence the firm’s decision on cooperation with knowledge producers. The findings indicate that the scale of industry-science linkages in Russian manufacturing is limited and generally hampered by low propensity of business to the R&D-based innovation strategies.

Existing research has highlighted the importance of cooperation in innovation. However, there still is insufficient understanding of how cooperation is linked to the stages of innovation process. Current working paper aims to answer the following research questions: (1) At what stages of innovation process do the companies cooperate more: when they create or commercialize innovation? (2) Does the cooperation in innovation depend on the relational learning capability? (3) On what stage does cooperation stronger influence the company's performance? We answer these questions by examining innovation cooperation on example of a sample of 157 Russian firms. The findings highlight the role of relational learning and indicate distinctive characteristics of cooperation at the early and the late innovation process stages.

We study Josephson junctions with weak links consisting of two parallel disordered arms with magnetic properties -- ferromagnetic, half-metallic or normal with magnetic impurities. In the case of long links, the Josephson effect is dominated by mesoscopic fluctuations. In this regime, the system realises a $\varphi_0$ junction with sample-dependent $\varphi_0$ and critical current. Cooper pair splitting between the two arms plays a major role and leads to $2\Phi_0$ periodicity of the current as a function of flux between the arms. We calculate the current and its flux and polarization dependence for the three types of magnetic links.

This paper is devoted to the explanation of selected bureaus’ behavior patterns in the soviet type of totalitarian dictatorships with the command economic model. It is a proven fact that the plan figures in the soviet economy were fabricated as a consequence of intrigues and secret negotiations between different interested parties. Generally, bureaus, as rational agents that minimize risk and maximize slack, should have been interested in reducing the plan figures, nevertheless, they strived to increase them. As examples, mass repression under dictatorships and overexpenditure of an administrative leverage at elections in non-democratic and quasi-democratic countries can be observed. In the article we develop a simple model of coordination between principal (dictator) and his agents (bureaus), which explain the mentioned paradoxical situation.

Following an old suggestion of M. Kontsevich, and inspired by recent work of A. Beilinson and B. Bhatt, we introduce a new version of periodic cyclic homology for DG agebras and DG categories. We call it co-periodic cyclic homology. It is always torsion, so that it vanishes in char 0. However, we show that co-periodic cyclic homology is derived-Morita invariant, and that it coincides with the usual periodic cyclic homology for smooth cohomologically bounded DG algebras over a torsion ring. For DG categories over a field of odd positive characteristic, we also establish a non-commutative generalization of the conjugate spectral sequence converging to our co-periodic cyclic homology groups.

An approach is proposed to determine structural shift in time-series assuming non-linear dependence of lagged values of dependent variable. Copulas are used to model non-linear dependence of time series components. Several nice properties of copula application to time series are discussed. To identify the break copula structural shift test is applied. Data on quarterly GDP growth rate for the US from 1947 till 2012 is used as an empirical example. It is shown that the proposed approach captures the recession of 1981-1982 as the key break date in GDP growth rate series time structure that cannot be identified by standard time series structural break tests.

This paper aims at presenting the research results of revealing a structural shift in copula-models of multivariate time-series. A nonparametric method of structural shift identification and estimation is used. The asymptotical characteristics (the probabilities of the I-type and II-type errors, and the probability of the estimation error) of the proposed method are analyzed. The simulation method verification results for Clayton and Gumbel copulas are presented and discussed. The empirical part of the paper is devoted to structural shift identification for multivariate time series of interest rates for Euro-, US Dollar- and Ruble-zones. The empirical application provides strong evidence of the efficiency for the proposed method of structural shift identification.

This work is devoted to the distribution of different referential devices in spoken discourse produced by healthy speakers and people with aphasia and its comparison to written discourse. We discuss some special annotation issues for the corpus of Pear film retellings (Russian CliPS) by people with aphasia (PWA), right hemisphere damage (RHD), and healthy speakers (HP for healthy people) of Russian. The study summarizes the comprehensive annotation schema developed for this task and the preliminary research of the referential choice features based on the corpus. Comparing retellings and written texts, we found a significant difference in the use of basic coreferential expressions between the two. Firstly, there is a significant difference in the distribution of basic NP types. Speakers use reduced devices such as zero anaphora or bare nouns in retellings more frequently than in written texts. There are also differences in the distribution of more granulated features such as the word order within an NP, the use of anaphoric and reduced expressions (demonstratives or zero NPs) for the first mention of an entity, and the inclusion of epistemic markers into NPs. We also found that the retellings produced by PWA and HP do not differ much in terms of the distribution of basic NP types. However, a detailed analysis of different NP types and taking into consideration various disfluencies reveals some prominent differences between the two populations. These include a difference in zero subject distribution, the frequency of non-referential NP links, the frequency of co-reference errors. While adapting the initial coreference annotation scheme we concluded that besides referential ambiguity, which is normally taken into account in spoken discourse analysis, and basic taxonomy of the referential devices (full NP vs. anaphoric pronoun vs. anaphoric zero), other features need to be considered

We study the role of (i) initial differences in shares of immobile workers between countries which stand for the agglomeration forces, and (ii) positive trade costs in the traditional sector which are related to the dispersion forces, in shaping the spatial pattern of the developed and transition countries. We show that on the trade liberalization path in skill-intensive industries, keeping high trade barriers in less skill-intensive sectors is enough to protect a transition country from de-industrialization. If trade liberalization in a skill-intensive sector is accompanied by decreasing trade barriers in the traditional sector, the developed country has a higher probability to become a Core. When partial agglomeration is stable, it is characterized by the Home Market Effect (HME).

One of the major problems facing Russian companies is the problem of differences between brand promises and the experience of actual consumer interaction with that brand, resulting in image destruction and the customers’ refusal from repeat purchases. Having taken as the basis the idea of gap analysis in perception of corporate brand values by different stakeholder groups (owners/top managers, personnel and customers), we have developed and tested a methodology of internal marketing management system assess ment, assuming that a significant gap between declared, shared, and perceived brand values is a consequence of absence or inefficient functioning of this system.

The Working Paper examines peculiarities of the Russian model of corporate governance and control in the banking sector. The study relies upon theoretical as well as applied research of corporate governance in Russian commercial banks featuring different forms of ownership. We focus on real interests of all stakeholders, namely bank and stock market regulators, bank owners, investors, top managers and other insiders. The Anglo-American concept of corporate governance, based on agency theory and implying outside investors’ control over banks through stock market, is found to bear limited relevance. We suggest some ways of overcoming the gap between formal institutions of governance and the real life.

This paper investigates how corporate governance of unlisted firms in an emerging market economy affects financing constraints, measured by the sensitivity of investment to cash flow. We develop two original corporate governance indices based on a large-scale survey of Russian enterprises – one for shareholder protection and one for transparency. We estimate standard investment regressions where the cash flow variable is interacted with our corporate governance indices and variables capturing the ownership structure. The central result is that better shareholder protection diminishes the cash flow sensitivity of investment, particularly in firms with an outside controlling owner and in firms with low managerial ownership. In contrast, more transparency exacerbates financing constraints in some cases. We address the problem of the endogeneity of corporate governance by using fixed-effects regressions and a novel instrumental variable based on particular legal provisions for corporate governance in Russia depending on the number of shareholders.

This paper aims to add to literature on the connection between corporate governance and corporate law development. “Corporate governance” came into vogue in the 1970s in the United States. It had become the subject of debate worldwide by scholars, regulators, investors etc. This paper considers the nature and extent of corporate law`s contribution to the development of corporate governance and vice versa. In recent years, Russia and most continental countries (Germany, France, Italy) have enacted significant corporate law reforms. In Europe these reforms aim to strengthen the mechanisms of internal governance, empower shareholders, enhance disclosure requirements, and toughen public enforcement, which are the most effective tools for countering abuses by dominant shareholders. It is widely discussed among legal professionals in Russia that there is now an urgent need for a comprehensive review and modernization of corporate law and governance. However, in the last two years the Russian Civil Code and Federal Law “On Joint Stock Companies” have been changed deeply. Under the new Civil Code, all legal entities (both commercial and non-commercial) are divided into corporate and unitary entities.
