I made a stupid mistake in multiple choice but I wrote the best economics essays I have ever written. Seriously, one of the leading edge conference booklets had their "environmental management in australia 2010" section set out as a detailed response to that essay question. The protectionist one was also easy as fuck.
The only part i found a little confusing (in retrospect) was the "net capital importer" question. Half of my friends discussed capital goods, the other half capital funds. So i'm not quite sure which one is correct...
