It is not bad...financial services keep recruiting, so studying econ may have an edge.
How about the master of economics in NUS?Usually how about their job and salary after graduation?I mean master by course.
it really depends on what job you can gettop companies may give you 6-8K depending, but you could also end up in a 2-3K job. There is no universal salary, all depends on your own hard work, relationship and a bit luck.
