In the booj "The End of Early Music," published by Oxford University Press in 2007, oboist and musicologist Bruce Haynes addresses questions about the evolution of music, its composition, performance, and listening. Drawing on his extensive practical and educational experience, he argues for the importance of engaging with the past. Particular attention is given to ...

This study examines the individual factors of artificial intelligence (AI) implementation by small and medium-sized enterprise (SME) owners, based on a survey of 499 respondents in Russia. Drawing on Innovation Diffusion Theory, the Technology Acceptance Model (TAM), and stakeholder-oriented sustainability approach, the analysis shows that SME owners who already use AI for private purposes are ...

Gift giving is a widespread social practice with a long history, which is an
important part of social relations. However, the gift giving of books may be difficult to
describe with the help of classical gift exchange theories. The aim of the present study
is to determine the palette of meanings exchanged between giver and receiver in the
process ...

This article examines changes in the quantum and structural characteristics of period and cohort fertility in Russia in the context of pro-natalist demographic policy pursued since 2006. The study assesses the significance of recent decades’ shifts for total fertility, the age profile of mothers, and their distribution by number of children born. The analysis draws ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Swendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for models in different universality classes: Ising model, Potts model with three components, and four-state Potts model. The overlap of two ...

The article presents the results of a comparative analysis of fertility indicators for Russian female cohorts born in the 1930s–1980s, obtained using two independent methods: (a) estimates based on the results of national surveys of women collecting information on the number of children ever born; and (b) estimates derived from specially constructed cohort age- and ...

This paper introduces a novel approach to identifying and operationalizing political connections of banks. We manually code 2,598 bankers who owned or worked in 115 Russian banks between 2015 and 2021 to classify political connections and uncover their institutional patterns through cluster analysis. We propose a set of variables that capture the origins, relevance, and ...

The relevance of the topic is related to the fact that after the complete abandonment of real values in the 1970s of the main means of international settlements - the US dollar – there is a growing feeling that money increasingly represents an illusory reality. The article begins with an analysis of the illusions associated ...

We study a model problem on the filtration of a conducting fluid through a
porous layer. A porous medium is presented as an assemblage of identical spherical
cells. Each cell consists of a porous core and liquid shell. We derive apriori estimates
for flow characteristics which show the specific behavior of the fluid. Our estimates
are validated numerically. ...

Context and relevance. Artificial intelligence is a technology with the potential to fundamentally transform all spheres of human life. Its rapid integration into everyday reality intensifies research dedicated to the psychology of using neural networks. However, the development of empirical research in the Russian scientific field is limited by the lack of validated psychodiagnostic tools that ...

This study analyzes art residencies in Russia as institutions that bring together artists, local contexts, and stakeholders. It focuses on three key aspects: strategies for institutional positioning within the art field and in relation to stakeholders; residents' practices regarding the local context; and the nature of the residencies' interactions with local residents. The institutionalization of ...

This article, based on a survey data from 1,860 Russian manufacturing enterprises, analyzes the
scale of enterprise participation in science-industry collaboration (SIC), defines the characteristics of
enterprises that are more actively involved in SIC, and identifies regional institutional factors that
contribute to increased enterprise participation in SIC using correlation analysis. It is shown that
Russian manufacturing firms are very ...

Исследование посвящено анализу институциональных усилий развивающихся стран по дедолларизации и укреплению роли национальных валют. На основе систематизации теоретических подходов к интернационализации валют авторы разрабатывают новый аналитический инструмент – Индекс институционального развития финансового рынка в национальных валютах. Методология индекса охватывает четыре ключевых направления политики: использование валюты в международных расчетах, создание валютных своп-линий между центральными банками, развитие ...

Within narrowly defined industries, the most productive firms produce far more than the least productive from the same inputs, and this dispersion widens in downturns. We build a tractable representative-agent model in which financial frictions—adverse selection and moral hazard—make firms sort endogenously into lenders, strategic defaulters, and producers. As credit conditions vary, the resulting misallocation ...

В аналитической записке обсуждается долгосрочно устойчивый уровень цены на российскую нефть. Это тот уровень, к которому цена нефти, вероятнее всего, будет тяготеть в долгосрочной перспективе. Потребность в его определении возникает по нескольким причинам. Во-первых, цена на нефть остается одним из ключевых экономических показателей российской экономики, определяющих экспорт, обменный курс рубля, прибыль, доходы и расходы бюджета, ...

The paper proposes a graphical model of a small open economy. The dynamics of the graphical model is then illustrated using impulse responses from the corresponding formal semi-structural model (QPM model). The authors have several goals in preparing this description of the graphical macroeconomic model. The first goal of the paper is to present an adapted ...

In this paper, we construct strong approximations for discrete-time Markov chains weakly converging to continuous diffusion processes, as well as for their perturbed counterparts. Under the assumption of bounded coefficients, we construct closely coupled versions of these processes on a shared probability space. In particular, for both non-degenerate and degenerate cases, we maximize the probability ...

This work develops a tractable model of price competition in fragmented markets where consumers consider both local and distant varieties, with cross-regional purchases subject to stochastic costs. Global competition and full localization emerge as polar cases; hybrid competition is not merely intermediate and exhibits distinctive features such as an endogenous price ceiling and non-monotonic entry ...

Elaborating on Welzel et al.'s "Cool Water Theory," our study zooms into the more limited (albeit still varied) framework conditions of Russia's huge territory. Within Russia's confines, we examine how the combination of moderately cool seasons with steady rain (i.e., Cool Water) affects sub-national areas' contemporary societal progress in two modernization indicators: material prosperity in ...

At the end of 2023, Russia updated its Strategy for Improving Financial Literacy and Developing Financial Culture Until 2030. Unlike the previous strategy, the current strategic goals include not only financial literacy but also financial culture. ‘Culture’ is normative and socially preferred behaviour. The updated strategy brings into focus the relationship between financial literacy and responsible financial behaviour. To explore this relationship, the authors rely on data from the All-Russian Survey of Consumer Finance (2020 and 2022). Socially ...

This work is devoted to a theoretical explanation of the Easterlin paradox, according to which long-term economic growth does not make average level of people's happiness increasing. By happiness, we mean the intensity of emotions people experience while comparing their new income with its expected value, or the target income with its original value. In the first case, ...
