@ Ari Ben Canaan:
I don't think predictions are not allowed because we did post forecast topics (well before the exams - one week?) for Economics Paper 2 and they were not deleted. 
It's another thing altogether, if the "probable topics" were right on spot 
 
Relax,i was just asking about important chapters 2 revise zat's all!!

 Did you make that username thinking of me?

Likely essay questions according to me: 
(1) Allocative/Productive efficiency
(2) National Income + standard of living
(3) One question on theory of firm - most probably on oligopoly
(4) Alternative objectives of government and conflicts
(5) Please God, let us have an essay on wages and wage differentials!! 

(6) Monetary/fiscal policies + Keynesian economics
As a precautionary measure, prepare unemployment and economic growth well too.
For the data-response, I think trade and exchange rates.
Any tips you want to share?
