The existence of a pure-strategy Nash equilibrium in a discrete ponds dilemma
Games and Economic Behavior. 2024. Vol. 147. P. 38–51.
In a variety of economic situations discrete agents choose one resource among several available resources and, once admitted to the resource of choice, divide it among fellow agents admitted there. The amount of the resource an agent gets is proportional to her relative ability to acquire this particular resource, what we refer to as an agent's weight at the resource. The relevant applications include students self-selecting into colleges, politicians self-selecting into races, and athletes self-selecting into teams. We find that this game has a pure-strategy Nash equilibrium in at least three special cases: 1) when agents have the same weight at each resource, 2) when all resources are the same, 3) when there are only two resources. We also show that this game always has an approximate Nash equilibrium when the number of players is large. Existence in the general case remains an open problem.

The year 2026 marks the 250th anniversary of Adam Smith’s “An inquiry into the nature and causes of the wealth of nations”, the work that had laid the foundations of economic science. The three factors of production Smith implicitly introduced — labor, land, and capital — no longer operate in their pure form: the digital ...

This paper studies the technical efficiency of Russian retail companies in 2019 to 2023 using stochastic frontier analysis (SFA) with the Battese and Coelli (1995) model. A translogarithmic production function is employed for estimations. The dependent variable is company revenue, and the production factors are the average number of employees, fixed assets, and assets less ...

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 ...

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 ...

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 ...

This study empirically tests the deposit channel hypothesis, which holds that increases in deposit markups cause liquidity outflows from the banking sector and a contraction in credit supply. The central question is whether deposit substitution effects, whereby depositors shift funds to other financial instruments during monetary tightening, are reflected in banks’ balance sheets and aggregate ...

В статье анализируется структурный разрыв между увеличивающейся когнитивной нагрузкой и снижающейся отдачей от неё. Подход, при котором развитие научных и образовательных школ, ориентированных на тренировку суждения, может стать альтернативой количественному наращиванию вычислительных мощностей, которое служит основной стратегией Китая и США. Применительно к России традиция фундаментального образования и сильных исследовательских школ приобретает в новых условиях значение ...

This paper assesses the relationship between financial literacy and over-indebtedness of Russian households using panel data from the Survey of Consumer Finances collected in Russia during 2018–2024. Russia is an interesting case: a relatively young consumer-finance market in which a lack of financial literacy may increase the likelihood of household over-indebtedness. To test this hypothesis, ...

We examine incentive compatibility of various school choice mechanisms as measured by the number of manipulating students. We find that Boston with Skips Mechanism, Secure Boston Mechanism, and Chinese Mechanism may have more manipulating students than Boston Mechanism. Similarly, Taiwan Mechanism with smaller deductions may induce more manipulating students than Taiwan Mechanism with larger deductions. ...

Manipulability is a threat to the successful design of centralized matching markets. However, in many applications some manipulation is inevitable and the designer wants to compare manipulable mechanisms.

Dozens of school districts and college admissions systems around the world have reformed their admissions rules in recent years. As the main motivation for these reforms, the policymakers cited the strategic flaws of the rules in place: students had incentives to game the system. However, after the reforms, almost none of the new rules became strategy-proof. We explain ...
