A PhD is a postgraduate doctoral degree, where you write a dissertation within (3 or) 4 years. PhD students do novel research, publish papers in the international literature, go to conferences, follow a few courses (40 ECTS) and teach (about 20% of your time). In order to apply for a PhD project or position at Erasmus School of Economics you should have an MPhil, MSc or MA degree in Economics, Econometrics, Business or a related field (depending on the PhD project). Find more information about a PhD here
