The article offers an overview of the use of survey experiments in political research by relying on available examples, bibliographic data and a content analysis of experimental manuscripts published in leading academic journals over the last two decades. After a short primer to the experimental approach, we discuss the development, applications and potential problems to internal and external validity in survey experimentation. The article also provides original examples, contrasting a traditional factorial and a more innovative conjoint design, to show how survey experiments can be used to test theory on relevant political topics. The main challenges and possibilities encountered in envisaging, planning and implementing survey experiments are examined. The article outlines the merits, limits and implications of the use of the experimental method in political research.

This paper discusses the consequences of EU migration control policies on irregular and transit migration in Turkey by focusing on African migrants. Our argument is that the EU's concern with transit migration through the Mediterranean and hence its externalization and securitization of migration control have contributed to Turkey's becoming a waiting room for irregular and transit migrants. Based on the findings of a survey with African migrants in İstanbul and analysis of secondary sources, we show that many African migrants get stranded in Turkey. In the absence of an institutional setup for migration management and the prevalence of a security approach, migrants are faced with humanitarian problems and human rights violations.
