Information on picking a topic and getting started with the MSc thesis: http://aalto-econ.fi/gradu
To enroll in the seminar you must have a topic accepted by a faculty member at the Department of Economics. The deadline for the Spring 2021 seminar is Oct 31st, 2020; for the Fall 2021 seminar the deadline is May 31, 2021. Obtaining approval may require some back-and-forth between the student and the faculty, so make sure to start the process several weeks before the deadline. You must notify (TBA -- name will appear here later) by email about the provisional topic and the faculty member who approved it. (If you would like to participate, but have no idea for a topic, you can simply go and ask a faculty member for a topic of their choice). After that you can enrol in the seminar via WebOodi.
The initial approved topic is not a binding commitment. Its purpose is to make sure that everyone who enrols is capable presenting their research plan in the second week of the semester. The topic and the advisor can be changed subject to the same approval procedure as the initial topic.
