Public Policy Information to the chair Public Policy, headed by Professor Dr. Monika Bütler. The department of «public policy» contributes to several areas of economic policy which are of scientific as well as of public interest. The main focus of our publications lies on social security systems (in particular the analysis of incentives), labor economics and political economics. We apply econometric methods with data from different sources. Contributions to current economic policy can be found on batz.ch, headed by Urs Birchler (University of Zurich), Marius Brülhart (University of Lausanne) and Monika Bütler (University of St.Gallen).
