Comparative Analysis on How Theories Support Policy Modelling

by Steve Hartmann. Abstract: This paper contributes to policy modelling theories and compares game theory, agenda-setting theory and institutional choice theory regarding policy modelling. For that matter a comparative analysis has been done. The most intensive research was identified for game theory. Game theory provides tools for policy modelling and models built upon. However, there are limits for the usage of game theory for example with more than three agents to interact. Institutional choice theory has not been researched as intensively and no clear author can be identified. Agenda setting theory is totally different theory using mass media as agenda setting process. Furthermore none of the chosen theories can contribute to policy modelling extensively without a combination of different theories. We argue that the combination of all three theories can extensively contribute to policy modelling.
