Title: The Game theory application in the Greek Elections of 2023. Political Competition, mass media and public opinion data management.

Abstract

The political elections in Greece 2023 were of prime importance and of very interesting aspects as far as the political competition is concerned. The dynamic interrelation of the political parties, the candidates and the issues were presented, considered and commented extensively during the preelection period. In the present study we use the game theory approach of competition analysis to represent in matrixes the competition between different parties and strategies toward different issues such as: economy, health, education, foreign affairs and defense, environment, new generation and young people, cooperation, behavior towards the opposite party/ candidate.We collected data form different sources of information: online newspapers, traditional newspapers, informational sites, debates, tv interviews, radio presentation, social media information and campaign publications. With group data analysis we find how many positive references the different strategies in the competition have in mass media and public opinion. The game theory matrixes give us information about the best clear strategies when a Nash equilibrium exists and if not, the mixed strategy approach is applied so as to calculate the possibilities and the payoffs of each strategy used in the pre- election period.This method creates a tool of expertise in the development of high-performance political campaigns because it gives the political parties the information needed about the strategies used in their presentation, their intensity and their efficacy.
