Application of cooperative game theory in Cournot oligopoly
Eryganov, Ivan ; Mazal,, Jan (referee) ; Hrdina, Jaroslav (advisor)
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.

A Price Analyses on the Imperfect Competitive Market
Fait, Petr ; MBA, Jiří Rozsíval, (referee) ; Škapa, Stanislav (advisor)
To sum up, Imperfect competitive markets are results of influence of various market factors. They consist of economies of scale, variety of legal restrictions, a high amount of production costs, a product differentiation, a territorial dispersion and an imperfect consumer awareness of the market. Firstly, the principal sorts of imperfect competitors are monopolies, oligopolies and monopolist competition. The ability to stipulate the price of a product is characteristic for these kinds of imperfect competitors. Thus they are called price-makers. These imperfect competitors deal with a diminishing demand curve, in other words there is a dependence of a price on the volume of production. Moreover, this ability is used to maximalize a profit. Referring to the imperfect competitor, the most common method of maximalizing the profit is price discrimination, therefore the company is able to divide its customers into several groups and stipulate a different price of a same product for each of them. Nevertheless, in practice due to above mentioned factors we run across the imperfect competition in most of the cases. In addiction, the imperfect competition might be considered as a theoretical state, which is very similar to share dealing in general.

Coalition Theory for Cournot's Oligopoly Model
Eryganov, Ivan ; Osička, Ondřej (referee) ; Hrdina, Jaroslav (advisor)
This bachelor thesis is devoted to the basic theoretical aspects of game theory, to the behavior of firms in oligopoly conditions and to the building of theory which describe behaviour in cooperative oligopoly games for Cournot's oligopoly. At this work are explained important definitions and they properties are demonstrated in the examples. Further work is focused on cooperative oligopoly games, describing their properties and defining a -characteristic function. Procedure of computing it and the description of some properties of cooperative oligopoly games are demonstrated on two examples.

A critical price analysis on the imperfect competitive market
Bábel, Martin ; Procházková, Kateřina (referee) ; Škapa, Stanislav (advisor)
Perfect competition can be considered as a theoretical state. For this reason, this work is focused on the imperfectly competitive market and pricing in it. The aim is to investigate in more detail how specific companies with elements of monopoly use their position to determine the price for their product and price discrimination - they are so-called price makers. The work analyzes specific approaches to the pricing strategy of these companies.

Tržní prostředí významných technologických firem
Raichel, Vilém
The bachelor thesis examines whether the most important technological companies of the modern world are in an oligopolistic position. The aim of the thesis is to confirm or reject the chosen oligopolistic theory, which will be specified in the research part of the thesis. This section will also briefly list selected companies. In the next section, the selected points will be applied to the chosen companies. The research focuses mainly on the current state of the companies, the years 2017 and 2018.
