This diploma thesis deals with conict economic situations based on game theory. In the beginning, basic models of conict situations and current popular software tools are dened not only for the general support of student education or for science, but also for solving economic problems in game theory. Based on this analysis, the conicting situation of two competing rms is being solved. Gradually, work goes deeper into areas of delay dierential equations that better show the behavior of two players on the market. Subsequently, these delayed dierential equations are projected into the Cournot model, for which a critical value is identied that switches the stability of two rms on the market due to the delayed realization of their outputs.

The present paper aims to show that the oligopoly problem is much more determined than commonly believed. In oligopoly prerequisites are likely to prevail inducing a 'normal' behaviour in accordance with profit maximization. This leads to a price combination located at an exactly definable line section. Finally some consequences upon economic policy are outlined. / Dieser Beitrag versucht zu zeigen, daß das Oligopolproblem wesentlich determinierter ist als gemeinhin angenommen. Im Oligopol liegen die Voraussetzungen besonders günstig, daß durch ein aus dem Streben nach Gewinnmaximierung abgeleitetes, "normales" Verhalten eine Preiskombination auf einem exakt abgrenzbaren Kurvenabschnitt zustande kommt. Abschließend werden wirtschaftspolitische Konsequenzen angedeutet.

This report discusses the IT archetypes "governance strategy" and how it could be linked to the IT benefits at the company. The study is based on IT investments that have taken place in ten banks operating in Sweden today, where the reality was modeled on the basis of a questionnaire survey and an additional interview. The aim was to examine whether it is possible to find any correlation between the governance in the banks and obtained benefits for an IT investments. While the competition is intensifying in most companies there is a greater demand for efficiency in IT. The need for IT solutions is greater than ever and the number of IT investments is increasing significantly in most workplaces today, especially on banks. But even if the investments are increasing in numbers it does not necessarily mean that all types of investments are effective and beneficial to the company. The benefits of IT investments are often difficult to measure, and the calculations become even more complex the larger the organization is. According to the framework Val IT Framework 2.0, from 2008, there was a global study made by Price Waterhouse Coopers in Belgium. The surveys, which were based on the response of 750 IT executives and managers, showed that the importance of IT is increasing and that there is much room for improvements in terms of returns on IT investments. To make it easier finding the underlying structures the study was divided into two parts, one benefit study and one archetype study. The structure of both the studies is based on research done by Peter Weill and Jeanne Ross in the field of IT governance and research in IT benefits by Gunasekaran. The main purpose of this report is to present a new way of thinking - where banks can predict the benefits of an IT investment just by viewing their corporate governance and invest in the most profitable IT investments only. The results of this study shows that there are some relations between received benefits in IT investments on the examined banks and their archetype. Most of the banks have an archetype that is similar to the IT duopoly and investments which generally results in strategic benefits.
