Aplikace kooperativní teorie her pro Cournotovy oligopoly / Application of cooperative game theory in Cournot oligopoly

Eryganov, Ivan January 2019 (has links)
This Master’s thesis deals with the application of cooperative game theory for solving the problems of Cournot's oligopolies. The knowledge of oligopoly theory and game theory has been elaborated to build a model describing the behavior of companies at a market that meets the preconditions of Cournot's oligopoly. The definition of cooperative game is based on the -characteristic function, which takes into account, compared to classical methods, that companies which are not in the coalition are pursuing their own profits, not suppressing coalition positions. The properties of the resulting cooperative games are examined in detail, focusing on monotony and convexity. Several theorems about these properties have been derived and their economic interpretations are given. Also, the question of calculation of the -characteristic function using the best-reply dynamics algorithm is being solved, and its convergence for a given type of games is justified. The model is applied to data from the oil market, which is further characterized by the results of the cooperative game.

Svensk dagligvaruhandel: En het potatis : En marknadsanalys av svensk dagligvaruhandel med huvudsakligt fokus på konkurrens och strategival. / The Swedish Grocery Retail Sector: A Hot Potato : A market analysis of the Swedish grocery retail sector with a primary focus on market competition and strategic choices

Steinauer, Felix, Strömlid, Louise January 2023 (has links)
This thesis aims to conduct a market analysis of the Swedish grocery retail market, with a primary focus on the current market competition and strategic choices. The market analysis is done in order to investigate whether insufficient competition is a contributing factor to the high food prices today. Furthermore, the essay aims to identify and evaluate the strategies used by market players. The market analysis has been conducted by using the Structure-Conduct-Performance model as a theoretical framework to map out and analyse the market's structure, strategy, and outcomes. Over the past year, the prices of groceries have increased drastically, resulting in significant media coverage of the market. The high prices, combined with the timeliness of the topic, justifies the choice of the essay’s subject. The methodology used in the essay is a combination of qualitative and quantitative methods. The market structure is analysed for two different years, 2012 and 2021, in order to enable the evaluation of the firms’ strategic choices. In the thesis’ conclusion, it is stated that the Swedish grocery retail sector is an oligopoly market with high market concentration, where the three largest firms account for 90 percent of the market shares. The market structure is a result of the underlying demand and the barriers of entry identified in the thesis. The strategies processed in the thesis are vertical integration, customer bonus systems, mergers and acquisitions, and price strategies. The evaluated strategic choices of the companies are deemed effective for increasing their market power, while also inhibiting competition and making market entry difficult. Because of this, the market outcome is considered not to be fully functional from a welfare perspective. Furthermore this study allows the assumption to be made that the current competitive situation is a contributing factor to today's high food prices. / Uppsatsen syftar till att göra en marknadsanalys av svensk dagligvaruhandel, med stort fokus på den rådande konkurrenssituationen. Detta görs för att utreda huruvida bristfällig konkurrens är en bidragande orsak till dagens höga matpriser eller inte. Vidare syftar uppsatsen till att kartlägga samt utvärdera de strategier som marknadens aktörer använder sig av. Marknadsanalysen har genomförts med Structure-Conduct-Performance-modellen som teoretisk grund för att kartlägga samt analysera marknadens struktur, strategi och utfall. Priserna på dagligvaror har under det senaste året ökat drastiskt, vilket har resulterat i att marknaden har getts stort medialt utrymme. De höga priserna i kombination med ämnets aktualitet motiverar valet av uppsatsämne. Metodvalet i uppsatsen är en kombination av kvalitativ och kvantitativ metod. Marknadsstrukturen undersöks för två olika år, 2012 och 2021, med anledning att möjliggöra utvärdering av aktörernas strategival. I uppsatsens slutsats konstateras det att den svenska dagligvaruhandeln är en oligopolmarknad med hög marknadskoncentration där de tre största aktörerna står för 90 procent av andelarna på marknaden. Marknadsstrukturen är ett resultat av den grundläggande efterfrågan som finns, samt de etableringshinder som identifierats i uppsatsen. De strategier som behandlas i uppsatsen är vertikal integration, kundbonussystem, fusioner och förvärv samt prissättningsstrategi. Dessa strategival utvärderas som effektiva vad gäller utökandet av aktörernas marknadsmakt, samtidigt som de hämmar konkurrens och försvårar för nyetablering på marknaden. Detta leder till att marknadens utfall inte ses vara helt välfungerande utifrån ett välfärdsperspektiv. Efter genomförandet av denna studie görs dessutom antagandet att den rådande konkurrenssituationen är en bidragande orsak till dagens höga matpriser.
