I am a student of comparative politics currently considering what specific topic I want for my Master's Thesis. On the basis of the choice, the university will allocate an appropriate professor - given that they understand the choice of course. However, the boundaries for topics are mainly limited by the field and the length; 80-100 pages. As such, I am unsure how wide or narrow I should aim to be with the thesis.
I have a general idea for the topic, and a fairly good understanding of the field, but the length is an abstract I find hard to deal with. Basically, how much should I limit myself in the scope and use of selected theory and empirical content?
Of course, this varies between universities and fields, but some general guidelines on determining how to go about determining what can reasonably be achieved with a year of writing for a Master's Thesis would be appreciated.
