Marko Klašnja is a post-doctoral fellow at the Center for the Study of Democratic Politics at Princeton University. His research mainly centers on the political economy of accountability in developing democracies. To examine the factors that hinder or promote the electoral sanctioning of corrupt politicians, Marko uses a variety approaches, including game-theoretic models, survey and natural experiments, and the analysis of large datasets (e.g. politicians’ wealth declarations and a large volume of public procurement contracts to measure corruption more precisely). He is also interested in the issues of political representativeness of social media data.
