IB Economics extended essay advice?

Hi, I'm only about a term through the IB, not sure doing it was the right choice, but that's another topic. Anyway, we've been told that we need to have registered our topic and question for the extended essay by mid December, and I was looking for a bit of advice.

I want to do it on Economics, as I enjoy it and am thinking about doing it at university. My idea at the moment would be something along the lines of "How and why did John Cowperthwaite's economic ideas and principles spread through Asia and Eastern Europe".

http://en.wikipedia.org/wiki/John_James_Cowperthwa... - gives a decent, very brief explanation of what he did. There are lots of other sites I could use for info by the way

I got the idea after watching "Britain's Trillion Pound Horror Story" a couple of weeks ago.

For those of you who are doing/have done the extended essay, does this seem like a decent title? Have you got any advice on how I could change it slightly, or if it's rubbish, could you suggest some other economics related titles, or a theme for one?

Having only studied economics for a term, I don't know a lot about the subject yet, but we're not writing it for quite a long time yet so that's not a problem.

If you're interested, these are my subjects: Higher: Economics, Maths, Chemistry. Standard: English, French, History
