Dear

As per market research , analyst , planning , and better job opportunities I would recommend BA economics Hons and plus you would do MBA finance or International business will give you best combination.

Management studies can get from MBA than why now make your foundation strong specially with economics Hons.

All the best

It aso depends on your interest. You can choose BBE if your interest lies in a professional course because BA Eco shall be not in depth of practical and theory but shall cover all basics.
In DU there is an entrance exam for BBE.

Good Luck.
