The research success of a university requires efficient recruiting. The talents of candidates are unobservable for administrators, and so they delegate hiring to the faculty who have better knowledge of the job market. Since professors dislike putting their own employment at risk, faculty, especially less productive, have an incentive to hire less productive candidates to insure against getting fired themselves. I argue that both tenure and strict long-term administrative positions mitigate this problem, and allow one to hire better candidates.

Contraherent cosheaves are globalizations of cotorsion (or similar) modules over commutative rings obtained by gluing together over a scheme. The category of contraherent cosheaves over a scheme is a Quillen exact category with exact functors of infinite product. Over a quasi-compact semi-separated scheme or a Noetherian scheme of finite Krull dimension (in a different version - over any locally Noetherian scheme), it also has enough projectives. We construct the derived co-contra correspondence, meaning an equivalence between appropriate derived categories of quasi-coherent sheaves and contraherent cosheaves, over a quasi-compact semi-separated scheme and, in a different form, over a Noetherian scheme with a dualizing complex. The former point of view allows us to obtain an explicit construction of Neeman's extraordinary inverse image functor f^! for a morphism of quasi-compact semi-separated schemes f. The latter approach provides an expanded version of the covariant Serre-Grothendieck duality theory and leads to Deligne's extraordinary inverse image functor f^! (which we denote by f^+) for a morphism of finite type f between Noetherian schemes. Semi-separated Noetherian stacks, affine Noetherian formal schemes, and ind-affine ind-schemes (together with the noncommutative analogues) are briefly discussed in the appendices.

We argue that multinational headquarter-subsidiary relations in international business remain undertheorized as a result of a dearth of constructs that capture and reflect the complex facets of such relations. Based on data from 40 interviews conducted with senior managers in 25 multinational corporations designed to chart both the evolving competitive arena in which they operate and, against this backdrop, the changing nature of the corporations architecture and network of headquarter-subsidiary relations, we make the case for a focus on subsidiary mandates, corporate parenting styles and collective psychological contracts, three constructs which we believe offer explanatory power in landscaping the contemporary nature of these relations. We suggest that insights garnered from these constructs may offer the prospect of charting and explaining a greater range of issues pertinent to headquarter-subsidiary relationships and, from a theoretical perspective, could serve to renew aspects of the debate on such relationships. Arising from this we present a series of propositions designed to explicate the value of these constructs in opening up potential lines of enquiry in multinational headquarter-subsidiary relations.

We considered the control problem for wireless sensor networks with a single time server node and a large number of client nodes. The cost functional of this control problem accumulates clock synchronization errors in the clients nodes and the energy consumption of the server over some time interval $[0,T]$. For all possible parameter values we found the structure of optimal control function. It was proved that for any optimal solution $\widehat{R}\left(t\right)$ there exist a time moment $\tau,$ $0\leq\tau<T$, such that $\hat{u}(t)=0,$ $t\in[\tau,T]$, i.e., the sending messages at times close to $T$ is not optimal. We showed that for sufficiently large $u_{1}$ the optimal solutions contain singular arcs. We found conditions on the model parameters under which different types of the optimal control are realized.

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).
