Better to go for MBA as it will open a number of opportunities not only in economics but also in the field of finance, marketing, operations, HR. There are numerous opportunities in these fields. You will get ample amount of opportunities to work in your field of interest. You can test yourself with fields like investment banking, relationship manager, risk analyst, brand manager, strategy manager, product research analyst, consultant and many more. So, in my view from a career and job prospective MBA is a better option.

You need to have maths in 12th for admission in BA economic honors.

To be eligible for BA economics (honors), it is mandatory to have mathematics as a mandatory subject.
