Abstract. Manipulation is a phenomenon when an agent or a group of agents misrepresent her/their preferences in the ballots in order to obtain a better outcome of the social choice. It has been proven that there is no not-dictatorial social choice rule which is nonmanipulable. There are two approaches to fi nd the least manipulable social choice rules. The fi rst one implies fi nding a theoretical formula for each rule. However, there are many known social choice rules and a list of manipulability indices which make this task very hard. The second approach is to generate a set of random profi les to obtain an approximate values of manipulability indices. We developed an algorithm which allows to get not approximate, but exact values of manipulability indices for any given social choice for the case of 3 alternatives. We provide the description of the algorithm, its optimizations, memory and time needed compared to the previously known algorithms, as well as the examples of the results.

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 ...

The global wine industry is transforming due to climate change challenges. Glocalization is increasingly relevant in winemaking, where geographical and cultural diversity requires context-specific solutions in the existing sustainability spectrum in viticulture. Despite growing interest in regenerative viticulture, existing research offers limited insight into how regenerative approaches are operationalized in practice. This study explores how ...

This study discusses the evolution of the management and organization of Soviet industrial ministries—sizeable structures designed to manage enterprises of specific industries. The ‘Soviet style’ enterprise management included operational (day-to-day) control over the volume of production, control over the cost of production, control over the technical level of production, and control over labour productivity. The ...

The book focuses on the concept of “socialist market, a cornerstone of political economy in Soviet-type societies undergoing economic reforms from the 1950s onward. Encouraged by the success of non-capitalist mixed economies, market reformers (also called 'market socialists') offered the communist ruling elites a remedy for the persistent crises of the planned economy. Besides optimal planning and ...

A convenient approach to optimally solving combinatorial optimization tasks is the Branch-and-Bound method.
Its branching heuristic can be learned to solve a large set of similar tasks. The promising results here are
achieved by the recently appeared on-policy reinforcement learning method based on the tree Markov Decision
Process. To overcome its main disadvantages, namely, very large training time ...

The article examines Trump’s tariff policy, proclaimed at the beginning of his second presidential term and its negative impact on the stability of the global economy. It is emphasized that the practice of manipulating import duties used by the Trump administration fundamentally contradicts the basic ideas on which the Multilateral trading system has been built since the early 1940s, in particular, predictability of mutual ...

Scientific collaboration among universities is traditionally studied by counting coauthored papers with different types of partners. Under this approach, the internal mechanisms of collaboration remain hidden and, without additional normalization, the results can be biased. In our study, we apply co-authorship network analysis to examine collaboration structures within university research networks. We use OpenAlex data ...

Collective decision-making is a part of everyday life in modern society. People invented a variety of voting procedures for aggregating individual preferences into a collective choice. However, the problem is that people can misrepresent their preferences in order to achieve a more preferable voting result. This phenomenon is called manipulation and is considered negative since ...

The degree of individual manipulability of positional aggregation procedures is evaluated for the dynamic voting model within the framework of the two-dimensional Downsian model. In the dynamic voting model, alternatives move in steps toward a central point while agents attempt to manipulate at each step. The share of manipulable profiles, i.e., the Nitzan-Kelly index, is ...

We study the school choice problem and propose a new criterion for comparing non-strategy-proof mechanisms: robustness to manipulations. Mechanism A is more robust than mechanism B if each student (given any preferences of this student and any profile of schools’ priorities) can potentially access a smaller set of schools via a profitable manipulation under mechanism A than under mechanism B. This criterion strengthens the two ...

Manipulation is a situation when an agent misrepresents his/her preferences to obtain a better result of an aggregation procedure. It was proven in literature, that there is no non-dictatorial aggregation procedure which is non-manipulable. A number of papers studying the degree of manipulability of aggregation procedures have been published since then. Such papers either look ...
