In this paper I study the crisis on Chinese stock market in the end of August 2015. I show that the crisis may be described as the change of preferences of the main investors, and that during several months one needs to consider two representative consumers with different utility functions in order to describe the behavior of investors.

The dynamics of the Russian economy in 2022 did not develop along the trajectories expected in most forecasts. Investments in fixed assets, contrary to expectations, decreased slightly; some industries have seen growth. The article offers an analysis of the 2022 results from the point of view of justification of views on the factors determining investment ...

The paper assesses some of the consequences of Russia’s accession to the World Trade Organization (WTO). Whereas much discussion about its costs and benefits happened during the WTO negotiations and in the first years after the accession, there was little said on the real consequences afterwards. The aim of the research is to assess the ...

The withdrawal of foreign companies from the Russian market due to a change in the political situation has been a new trend for the Russian economy. The study shows that the actual scale of closure of foreign legal entities is insignificant, and even smaller than in previous years: the maximum number of legal entities was ...

Customer-centricity (client-centricity) is a new concept for Russian public governance. However, since 2022, the implementation of the relevant principles has been brought to the level of a national strategic initiative. The article proposes an analysis of the issues to be considered when implementing customer-centricity in the practice of government agencies and institutions. The article examines ...

In this paper, new numerical invariants of structurally unstable vector fields in the plane
are found. One of the main tools is an improved asymptotics of sparkling saddle connections that
occur when a separatrix loop of a hyperbolic saddle breaks. Another main tool is a new topological
invariant of two arithmetic progressions, both perturbed and unperturbed, on the ...

The booming retail trade and the above-target consumer prices inflation in 2023–2024 in Russia, amid tightening monetary policy stance, raise an issue of the strength of the monetary policy interest rate channel. The focus of our paper is the interest rate elasticity (given inflation expectations) of a household’s loan request probability. We argue that a ...

AI errors pose a significant challenge, hindering real-world applications. This work introduces a novel approach to cope with AI errors using weakly supervised error correctors that guarantee a specific level of error reduction. Our correctors have low computational cost and can be used to decide whether to abstain from making an unsafe classification. We provide ...

High-dimensional tabular data are common in biomedical and clinical research, yet conventional machine learning methods often struggle in such settings due to data scarcity, feature redundancy, and limited generalization. In this study, we systematically evaluate Synolitic Graph Neural Networks (SGNNs), a framework that transforms high-dimensional samples into sample-specific graphs by training ensembles of low-dimensional pairwise ...

This study presents on-the-fly identification and multi-step prediction of nonlinear systems with delayed inputs using a dynamic neural network combined with a smooth projection onto ellipsoids. The projection enforces parameter constraints that guarantee stability, while a Lyapunov–Krasovskii analysis yields computable ultimate error bounds. Riccati-type matrix inequalities are derived, providing an efficient vectorization–projection–devectorization implementation suitable for ...

The approximation of tensors in a low-para metric format is a crucial component in many mathematical modelling and data analysis tasks. Among the widely used low-parametric representations, the canonical polyadic (CP) decomposition is known to be very efficient. Nowadays, most algorithms for CP approximation aim to construct the approximation in the Frobenius norm; however, some ...

This paper investigates the relationship between online recruitment and unemployment in Russia within the Beveridge curve (the unemployment–vacancy curve) framework. Using panel data for 81 Russian regions over the period 2006–2022, we examine how the expansion of online job boards affects regional unemployment dynamics. The empirical
analysis is based on fi xed- effects and instrumental- variable ...

In this paper the structural stability of generic families of vector fields of the PC-HC class on the two-dimensional sphere is proved. A classification of these families up to moderate equivalence in neighborhoods of their large bifurcation supports is presented, based on such invariants as the configuration and the characteristic set. The realization lemma is proved. ...

A vertex subset of a graph is called a \textit{distance-$k$ independent set} if the distance between any two of its distinct vertices is at least $k + 1$. For all $n,k \geq 1$, we determine the minimum possible number of inclusion-wise maximal distance-$k$ independent sets among all $n$-vertex trees. It equals~$n$ if $n \leq k ...

We deal with the global in time weak solutions to the 1D compressible Navier-Stokes system of equations for large discontinuous initial data and nonhomogeneous boundary conditions of three standard types. We prove the Lipschitz-type continuous dependence of the solution $(\eta,u,\theta)$, in a norm slightly stronger than $L^{2,\infty}(Q)\times L^2(Q)\times L^2(Q)$, on the initial data $(\eta^0,u^0,e^0)$ in a ...

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...
