The research group is renowned for its contributions to theory-based empirical research on the organisation of firms, industries, and markets, and has a robust publication record in leading international journals. The PhD project will focus on applying economic theories such as real options theory and signalling theory to strategic topics including (but not limited to) strategic (re)positioning of firms, R&D collaboration, startup acquisition, and startup wage setting. The work will be primarily empirical, leveraging modern micro-econometric methods and large-scale datasets, including administrative data. The exact research topic will be determined collaboratively between the successful candidate and the supervisors, Dr. Jolanda Hessels and Prof. Dr. Enrico Pennings. As a PhD student, you will join a vibrant, internationally oriented team within the Department of Applied Economics. You will have the option to affiliate with either the Erasmus Research Institute of Management (ERIM) or the Tinbergen Institute, depending on your research interests.
