Balanced growth paths are typical research subjects for models of macroeconomic dynamics. Balanced growth paths are model solutions that assume constant policy parameters (such as tax rate) and allow for monotonous and proportional growth of model components. In this paper, we construct and test a model with policy switching based on economic retrospective voting: the model allows to switch parties in office if an electorally important indicator exhibits decline. A change of ruling party brings about a change in policy. If the second party is then voted out of the office, the system experiences endogenous policy switching. Within this framework, we introduce the term "cyclically balanced growth paths", i.e. non-monotonous solutions where the proportionality of components is broken and then restored every political cycle. We conduct the analysis using differential equations theory and numerical experiments

In this article, we investigate wave packet and solitary wave dynamics in the Whitham–Ostrovsky (WO) equation. By means of a multiple-scales expansion, we formally derive a nonlinear Schrödinger (NLS) equation governing the envelope evolution.The corresponding modulational stability diagram is then obtained using the Lighthill criterion. We show that sufficiently large values of the low-frequency dispersive term render ...

Punishment plays a crucial role in driving norm change by incentivizing compliance with evolving shared normative expectations. Punitive measures typically encompass two components: a communicative effect, which delineates inappropriate conduct, and an institutionalized procedure that facilitates sanction enforcement. This study specifically investigates the latter dimension, examining how the mere existence of a punishment institution influences ...

The global transportation sector is undergoing a major transformation associated with the transition to a low-carbon economy and the expanded use of alternative energy sources. In recent decades, the substitution of petroleum-based motor fuels with their substitutes – primarily biofuels and electric power (electric vehicles) – in light-duty road transport has accelerated. Public policy at ...

The year 2025 was marked by deepening contradictions between the leading world powers in world politics and economics. The dominant paradigm is the transition of the world's leading players, primarily the United States, to fierce competition in order to promote and realize national interests. In this context, political polarization has increased in many countries of ...

We consider 3-diffeomorphisms with source–sink dynamics where Smale solenoids play the role of the source and the sink (NSSS-diffeomorphisms). It is known that such diffeomorphisms exist only on lens spaces. On the 3-sphere, every NSSS-diffeomorphism is associated with an exchangeable braid. An exchangeable braid with the strand number n was constructed for each n 3 in such a way ...

The study compares the national artificial intelligence (AI) strategies of the United States, China and Russia, assessing their substantive completeness and governance logics. It employs a hybrid framework that combines governance approaches (anticipatory, reflexive, experimentalist and tentative) with a content analysis of the structures of the strategies. The results show that the United States relies ...

We study hyperbolic chaotic dynamics for maps of a two-dimensional torus. We introduce a two-parameter family of diffeomorphisms which, as we show, demonstrates all types of hyperbolic chaotic dynamics that can appear in the two-dimensional case. In addition, we describe all the bifurcations responsible for the transitions between these chaotic regimes. ...

Гомеоморфизмы топологических пространств называются эквивалентными по надстройке, если надстройки над ними топологически эквивалентны. В частности, топологически сопряженные гомеоморфизмы эквивалентны по надстройке. Известно, что для гомологически неприводимых гомеоморфизмов их топологическая сопряженность является необходимым и достаточным условием их эквивалентности по надстройке. Тогда как инварианты топологической сопряженности гомологически приводимых гомеоморфизмов во многих случаях являются избыточными для эквивалентности по ...

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.

This paper examines echo state networks (ESNs), one of the most prevalent approaches to
implementing reservoir computing. An ESN consists of a recurrent neural network with fixed (untrained)
weights and a readout layer that is typically linear and trainable. This approach enables the creation of energyefficient and computationally efficient neural networks capable of real-time learning. However, since ...

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 ...
