Christoph Michael Hindermann uses a statistical approach to analyze the impact of economic freedom on state legitimacy. Based on multiple regression models, the author not only extracts the determinants of legitimacy but also shows that rule of law is the most important area of economic freedom for legitimacy. In addition, the results also indicate that democracies are not necessarily more legitimate than autocracies and that wealthier countries are, ceteris paribus, perceived as less legitimate. Due to the strong quantitative approach, this thesis contributes not only to the political theory of liberalism and to the field of institutional economics but also enriches the debate on how a legitimate state ought to be.
