I am a currently in an MSc program in economics, and I'll be writing my master's thesis in about a year. I have a variety of interests, including game theory, statistics, and trading strategies. I'm also on the fence about applying to PhD programs in economics and finance. My question is as follows:
Given that economics is a broadly defined field that, in a certain sense, encompasses finance, how appropriate would it be to write a thesis on, say, the effectiveness of a particular type of trading strategy, or more broadly, on the use of certain statistical methods in finance? Would the department react negatively to my choosing something that is maybe more closely related to statistics or finance than it is to economics? Or would they welcome proposals that are somewhat multi-departmental?
Maybe I'm looking at this in the wrong light, but I don't know much about master's thesis expectations.
