I did economics and I don't regret it.
I agree with Pin that economics is not always the most practical - basically, you'll have subjects that go deep into policy and theories that you'll never really use unless you become a researcher or policy maker. But to become this, you'll have to get phd and so your education will be very long. In the most narrow sense, yeah, you should aim for a more practical degree that will get you a specific job after getting your bachelors.
In a bit broader sense, economics is (for me) more interesting and challenging than accounting and will give you quite a broad sense of skills. You can branch out to a lot of different discplines with it. For example, I discovered I quite like stats and econometrics, so will zoom in in this particular direction.
But none of degrees in this field would be useless. I wouldn't advise you to choose managment though, but that's not an informed opinion. I just don't really understand what you study in managment, so I would have to see the curriculum.
