In this paper, we introduсe a simple new theory on mixed сompetition between oligopolistiс firms and the competitive fringe, assuming a comparative advantage for big firms and free entry for small firms. Oligopolies are defined as conglomerates, each part of which benefits from joint operations through lower costs. Our theory implies that (i) industries with a few oligopolies arise as a stable outcome of mixed competition; (ii) mixed competition differs from the monopolistic competition of single-product firms due to the underproduction of oligopolistic firms and differs from pure oligopolistic competition since constraints on this underproduction are imposed by the competitive fringe; (iii) a positive shock in the market size an strengthen or weaken the competitiveness of the economy through the growth of the number of oligopolies.

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 ...

This article analyzes recent trends in the global fuel cell electric vehicle market, including declining sales and weakening government incentives, China's support for the development of hydrogen-powered trucks. It shows that the purchase price and fuel costs of hydrogen vehicles are higher than those of diesel and electric vehicles. Hydrogen from coal and natural gas ...

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 ...

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 ...

Digital public procurement is increasingly implemented through e-procurement platforms, yet evidence on the governance capabilities needed to deliver transparency, coordination and organisational learning remains limited outside high-capacity contexts. This article reframes public procurement as a socio-technical platform ecosystem and develops an ecosystem capability framework that links three tiers (government, platform operators and users) to three ...

Small and medium-sized enterprises (SMEs) operate under conditions of chronic resource constraints, which makes it important to study strategies capable of transforming available resources into sustainable financial outcomes. One such strategy is entrepreneurial bricolage - the unconventional recombination of existing resources to address organizational challenges. This article examines the impact of bricolage on SME performance, ...

This study assesses the impact of the European Central Bank's (ECB) Unconventional Monetary Policy (UMP) on economic growth via its effects on sovereign bond yields in the Eurozone. Unlike previous studies that focus on high-frequency data and short-term effects, this study provides evidence on the long-term effects of the ECB's asset purchases on key macroeconomic ...

The paper examines changes in the economic affordability of cigarettes in Russian regions in 2011–2023. Using fixed-effects models, it estimates the impact of prices, incomes, and tobacco affordability (the ratio of per capita income to cigarette price), on three indicators: retail sales of cigarettes per capita, adult population spending on tobacco products, and the share of these ...

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, ...

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

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 ...

Label prediction in neural networks (NNs) has O(n) complexity proportional to the number of classes. This holds true for classification using fully connected layers and cosine similarity with some set of class prototypes.
