Comparative Politics and Government are key fields of Political Science. They deal with basic forms and specific systems of government in a comparative perspective. In Comparative Politics and Government, students analyze political institutions and constitutions, the political process of decision-making, and policies. They investigate the interactions between political institutions and political actors and their logics of action. Objects of analysis in Comparative Politics and Government are among others: government institutions, parliaments, political parties and party systems, interest groups, political cultures, political participation (e.g. voting behaviour, protest behaviour) as well as the analysis of particular policies such as economic policy, social policy, environmental policy, or health policy.
