The Quality of Government (QoG) Institute was founded in 2004 by Professor Bo Rothstein and Professor Sören Holmberg. It is an independent research institute within the Department of Political Science at the University of Gothenburg. We are about 30 researchers who conduct and promote research on the causes, consequences and nature of Good Governance and the Quality of Government (QoG) - that is, trustworthy, reliable, impartial, uncorrupted and competent government institutions. Our research addresses the questions of how to create and maintain high quality government institutions and how the quality of such institutions influences public policy and socio-economic conditions in a broader sense. While Quality of Government is our common intellectual focal point, we apply a variety of theoretical and methodological perspectives. Around thirty researchers are currently engaged in different projects organized or funded by the QoG Institute. A central part of establishing the QoG Institute has been the construction of a comparative data base and we believe that we now have the most complete data set pertaining to this type of research. We offer several open-source datasets, a variable search tool, visualization tools and some extra information, all about Quality of Government.
