Research Topic
Policy evaluation with normative and empirical inputs: Case of predistribution
The aim of my research is to explore desirable institutional proposals of social security against the backdrop of ongoing inequality and poverty with no clear vision of social security for twenty-first century. My research is primarily a work of normative political theory (political philosophy) with the emphasis on how theoretical insights can be used for policy evaluations. I do this by utilising empirical methodologies including survey experiments.
