The current study is based on testimony of the linked employee-customer misbehavior model construct developed by Daunt & Harris (2014) adopted and applied to the international service context. According to a different research setting additional construct variables and hypotheses are suggested. The empirical evidence of the proposed model is based on the sample of 275 observations including the sub-sample of 128 customers in UK countries and a second sub-sample of 147 Russian customers of HORECA sector in both settings. The profound results of the study demonstrated the ample empirical evidence for model validity and hypothesized interrelations. Detected service dysfunction creates a negative effect on customer loyalty and WOM. The increase of the service deviance and employee misbehavior level provokes the customer misbehavior harshness in both UK and Russian samples.

This paper deals with a model of economic growth, which we expand to include endogenous policy switching based on retrospective voting. It is shown that under certain conditions the solution has a special form that we call a cyclically balanced growth path. This type of solution is an analogue to balanced growth paths, which often occur in growth models with constant policies. Cyclically balanced growth paths are investigated analytically, and the growth rate over the cycle has been found. Results of numerical experiments are also provided and possible empirical applications of the model are outlined

  This paper demonstrates that cyclical movements of major industrial market groups (durable and nondurable consumer products, equipment, materials and supplies) have important peculiarities in Russia and in the US. It allows a better understanding of business cycles in national economies determined with their specific structural features. Based on a statistical analysis of monthly indexes of industrial output (for Russia the relevant indexes were specially calculated by the author), one can conclude that in Russia the dynamics of industrial output do not dependent so much on demand but rather on supply of products. This is explained through both weak diversification of the Russian economy as well as its high degree of monopolization and exceptional role of imports in consumer and investment expenditures.

We show that the partially spherical cyclotomic rational Cherednik algebra (obtained from the full rational Cherednik algebra by averaging out the cyclotomic part of the underlying reflection group) has four other descriptions: (1) as a subalgebra of the degenerate DAHA of type A given by generators; (2) as an algebra given by generators and relations; (3) as an algebra of differential-reflection operators preserving some spaces of functions; (4) as equivariant Borel-Moore homology of a certain variety. Also, we define a new q-deformation of this algebra, which we call cyclotomic DAHA. Namely, we give a q-deformation of each of the above four descriptions of the partially spherical rational Cherednik algebra, replacing differential operators with difference operators, degenerate DAHA with DAHA, and homology with K-theory, and show that they give the same algebra. In addition, we show that spherical cyclotomic DAHA are quantizations of certain multiplicative quiver and bow varieties, which may be interpreted as K-theoretic Coulomb branches of a framed quiver gauge theory. Finally, we apply cyclotomic DAHA to prove new flatness results for various kinds of spaces of q-deformed quasiinvariants. In the appendix by H. Nakajima and D. Yamakawa (added in version 2), the authors explain the relations between multiplicative bow varieties and (various versions of) multiplicative quiver varieties for a cyclic quiver.

For each del Pezzo surface $S$ with du Val singularities, we determine whether it admits a $(-K_S)$-polar cylinder or not. If it allows one, then we present an effective divisor $D$ that is $\mathbb{Q}$-linearly equivalent to $-K_S$ and such that the open set $S\setminus\mathrm{Supp}(D)$ is a cylinder. As a corollary, we classify all the del Pezzo surfaces with du Val singularities that admit nontrivial $\mathbb{G}_a$-actions on their affine cones.

The modernisation of the Ukrainian economy and state continues to develop at an unsatisfactory pace due to a lack of pro-reform political consensus. The two upcoming election campaigns in 2019 (presidential and parliamentary) make the reform process even slower and additionally put its effectiveness and sustainability under risk. The international community has a limited toolkit to overcome this stalemate.

The ocial institutions (NBER, OECD, CEPR and others) provide business cycle chronology with a lag from 3 months up to several years. Markov-Switching Dynamic Factor Model (MS-DFM) allows to produce the turning points more timely. The Kalman lter estimates of the model can be obtained in one step with limited number of series or in two steps on a much richer dataset. While the choice of correct series is a challenge for the one-step method, the problem of the two-step method is the potential misspeci cation. In this paper we apply one-step and two-step approaches to the French data and compare their performance. Both methods give qualitatively similar results and prove to reproduce the OECD business cycle chronology on the 1993-2014 monthly sample well. We nd that the two-step method is more precise in determining the beginnings and the ends of recessions. Also, both methods produce extra signals corresponding to downturns which were too short to belong to OECD chronology of recessions.

This paper establishes a reference chronology for the Russian economic cycle from the early 1980s to mid-2015. To detect peaks and troughs, we tested nine monthly indices as reference series, three methods of seasonal adjustments (X-12-ARIMA, TRAMO/SEATS, and CAMPLET), and four methods for dating cyclical turning points (local min/max, Bry-Boschan, Harding-Pagan, and Markov-Switching model). As these more or less formal methods led to different estimates, any sensible choice was possible only on the grounds of informal considerations. The final set of turning points looks plausible and separates expansions and contractions in an explicable manner, but further discussions are needed to establish a consensus between experts.

Data Envelopment Analysis is a well-known non-parametric technique of efficiency evaluation which is actively used in many economic applications. However, DEA is not very well applicable when a sample consists of firms operating under drastically different conditions. Generally, it is difficult to define to what extent the analyzed sample is heterogeneous. We offer a new method of efficiency estimation based on a sequential exclusion of alternatives and standard DEA approach. This allows to assess efficiency in the case of heterogeneous set of firms. We obtain a connection between efficiency scores obtained via standard DEA model and the ones obtained via our algorithm. We also evaluate 29 Russian universities and compare results obtained by two techniques.

In codifying intellectual property rights, Russian legislators have left what standards of originality and creativity can be considered criteria of copyrightability a moot point. Nevertheless, it is crucial for answering questions about where the lower boundary of copyrightability lies and, consequently, what intellectual products that have an insignificant creative component, but are of high economic importance – such as databases, computer software, advertisement slogans or design work – should be copyrightable. This article addresses the problem of identifying criteria for copyrightability and non-copyrightability in the Russian legal literature by modeling various types of demarcation criteria and analyzing their strong and weak points. Analyzing debates in the legal literature warrant the conclusion that there is a trend to set looser standards for originality and creativity and grant copyright protection to works of low authorship.

The issue of instrument choice is vital for climate policy. Carbon pricing is used next to a range of traditional energy taxes and renewable energy policies such as feed-in tariffs and minimal renewable generation targets. Several countries introduced carbon taxes alongside existing energy taxes such as excise duties on vehicle fuels. Since 2005, the EU Emissions Trading Scheme (EU ETS) has attached a direct price to the GHG emissions of ETS companies. The combination of multiple instruments and explicit and indirect carbon price signals created a complex and frequently changing institutional landscape that blurs the contribution of each policy instrument. Can the decarbonization of the European economy be attributed to carbon price instruments or to renewable energy policies together with other fiscal instruments? This paper clarifies the relative impact of explicit carbon price instruments (carbon taxes and EU ETS) compared to other instruments, namely renewable energy policies and indirect carbon price signals (general energy taxes). The methodology is based on the calculation of the implicit carbon price in existing fiscal systems. On the basis of panel data for 30 European countries 1995–2016, several fixed-effect regression estimations were performed. The results indicate a greater but decreasing impact of price instruments on carbon intensity compared to renewable energy policies and a greater but decreasing relative impact of indirect price signals compared to explicit ones.

Can decentralization of firms be successful in an environment with weak institutions? Decentralization can do a great job for improving firms’ efficiency and competitiveness by creating opportunities for quicker and more competent decision-making and enhancing motivation of employees. However, decentralization is associated with a substantial increase in agency risk, which is particularly important for firms that operate under weak institutions. Hence, the popular belief is that in countries with weak institutions, firms are unable to successfully decentralize. In this paper, we study evidence from Russian firms to challenge this belief. Following anecdotal evidence and trends observed in the data, we introduce the notions of real decentralization for firms that decentralize decision-making to competitively hired professionals and cautious decentralizationfor firms that decentralize to people hired through connections. We demonstrate that really decentralized firms are, on average, significantly more likely to invest even in Russian weak institutional conditions. We also show that the gap in investment between really decentralized and other firms declines as corruption grows. Empirical research presented in the paper implies that there still can be significant room for decentralization even in an environment with weak institutions, such as that of Russia. However, as the role of non-market factors (such as corruption) in firms’ prosperity increases, the potential value of decentralization for the firms declines.

Ability to make collective agreements determines life of many organizations. But does it matter for the decision to make a new organization? On the data of 82 homeowners associations (HOAs) in Moscow and Perm factors that underpin HOA formation are studied. A logit-regression analysis is used. Ability of tenants to resolve the collective action problem in operating housing infrastructure shows its importance along with the physical characteristics of an apartment building. Thus HOA formation by homeowners is a signal of their ability to manage a house. Collective action paradox begins to play role not only ex post, but also ex ante, prior to organization’s establishment.

This research is devoted to the comparison of the declarations of independence of the United States and Spanish American nations. For the first time in historiography the exhaustive list of Spanish American declarations of independence is compiled. The questions risen by this attempted comparison lead to a reconsideration of the main problems of the New World independence movements and in the final account, to the discussion of a nature of the British and the Spanish colonial societies in Americas, and thus do not have clear and final answers.

We consider L^p-Wasserstein distances on a subset of probability measures. If the subset of interest appears to be a simplex, these distances are determined by their values on extreme points of the simplex. We show that this fact is a corollary of the following decomposition result: an optimal transport plan can be represented as a mixture of optimal transport plans between extreme points of the simplex. This fact can be generalized to the Kantorovich problem with additional linear restriction and the associated Wasserstein-like distances. We prove that the decomposition is possible, if marginal measures are elements of a simplex that is compatible with the additional restriction.
