Variational Inequalities, Nash Equilibrium Problems and Applications: Unification Dynamics in Networks
Ch. 9. P. 157–174.
We study game equilibria in a model of production and externalities
in network with two types of agents who possess different productivities. Each
agent may invest a part of her endowment (for instance, time or money) on the
first stage; consumption on the second period depends on her own investment
and productivity as well as on the investments of her neighbors in the network.
Three ways of agent’s behavior are possible: passive (no investment), active (a part
of endowment is invested) and hyperactive (the whole endowment is invested).
We introduce adjustment dynamics and study consequences of junction of two
regular networks with different productivities of agents. We use the projectionbased
method for solving variational inequalities for the description of adjustment
dynamics in networks.

The impact of state subsidies on Russia's post-Soviet dairy output remains controversial; this study provides an empirical analysis of that relationship. Using an unbalanced panel dataset of 123 dairy enterprises in the Leningrad Region spanning the period from 2010 to 2023, we employ stochastic frontier analysis to assess these relationships. The results indicate that subsidies ...

This note shows that under the unrestricted domain, there exists a choice liberal and Nash implementable social choice rule if and only if there are at least three players and the outcome set is at least twice as large as the player set. A social choice rule is choice liberal if and only if for ...

Education has expanded rapidly in Sub-Saharan Africa, yet productivity growth, formal employment and sectoral growth remain uneven. This divergence motivates a structured narrative review of why a growing stock of human capital has not translated consistently into structural transformation across the region. Drawing on 113 formal-corpus sources selected through structured searches and a documented curated ...

Previous EEG studies demonstrated ample evidence for a major influence of morphological regularity on inflectional processing. However, regularity effects may be attributed to different properties of inflectional classes: to type frequency, to productivity, or to defaultness (assumed only in some models). In many languages, these factors cannot be teased apart, but it is possible in ...

We prove that every finite two-person shortest path game, where the local cost of every move is positive for each player, has a Nash equilibrium (NE) in pure stationary strategies, which can be computed in polynomial time. We also extend the existence result to infinite graphs with finite outdegrees. Moreover, our proof gives that a ...

The study is aimed at developing a methodology for assessing the parameters of ecosystem functioning using multispectral remote sensing data (MRSD) within the information-thermodynamic approach. This approach calculates the main components of the energy balance of a biogeocenosis as an open dynamic system that transforms solar energy due to the non-equilibrium of living matter, based ...

In several recent papers some concepts of convex analysis were extended to discrete sets. This paper is one more step in this direction. It is well known that a local minimum of a convex function is always its global minimum. We study some discrete objects that share this property and provide several examples of convex ...

Abstract
Working memory refers to the capability of the nervous system to selectively retain short-term memories in an active state. The long-standing viewpoint is that neurons play an indispensable role and working memory is encoded by synaptic plasticity. Furthermore, some recent studies have shown that calcium signaling assists the memory processes and the working memory might ...

In this paper we propose a new notion of a clique reliability. The clique reliability is understood as the ratio of the number of statistically significant links in a clique to the number of edges of the clique. This notion relies on a recently proposed original technique for separating inferences about pairwise connections between vertices ...

The paper proposes a game theory model of price oligopoly with a heterogeneous product, where total demand depends linearly on the minimum market price. This model develops the Bertrand oligopoly for the case of imperfect price elasticity of demand. The most interesting result is an asymmetric Nash equilibrium with different prices and sales in the ...

We prove that a deterministic n-person shortest path game has a Nash equlibrium in
pure and stationary strategies if it is edge-symmetric (that is (u, v) is a move whenever (v, u) is, apart from moves entering terminal vertices) and the length of every
move is positive for each player. Both conditions are essential, though it remains ...

In 1975 the first author proved that every finite tight two-person game form g is Nashsolvable,
that is, for every payoffs u and w of two players the obtained normal form game
(g; u,w) has a Nash equilibrium (NE) in pure strategies. Several proofs of this theorem
were obtained later. Here we strengthen the result and give a ...

At the middle of the 2000-th, scientists studying the functioning of insect communities identified four basic patterns of the organizational structure of such communities. (i) Cooperation is more developed in groups with strong kinship. (ii) Cooperation in species with large colony sizes is often more developed than in species with small colony sizes. And small-sized ...

This paper shows that the industrial origins of productivity growth in Czechia, Hungary, and Slovenia (CEE-3) and Russia before 2008 were similar and driven by manufacturing industries. The contribution of manufacturing industries to multifactor productivity (MFP) growth is substantial. In CEE-3, it exceeded market services. The contribution of labor reallocation to labor productivity growth was ...
