Economics

First of all, you need to understand that specialization should be chosen on the basis of your interest in the field than anything else. For example, a lot of students choose Finance or Marketing as their specialization only to realize that they always loved operations or HR or something else. So figure out where your interest lies. There are many psychometric tests that can help you understand your areas of interest and what specialization might be the best for you. Deciding your specialization on the basis of your past academics is not the best way to go about it. Most of the people will probably tell you to take up Finance as you've done Economics in the past. But what if you like Marketing or some other specialization over Finance? Won't you take it up? To go about choosing your specialization, understand what each specialization really demands and the kind of opportunities available. Also, irrespective of your specialization, after a point of time in your career, you will be doing pretty much everything. Think of your short term, medium term, and long term plans (not concrete, but a fair idea) and then see if the specialization will equip you with the desired skills. All the best.

In my view, more of finance related course is better like Accounting, Investment Management, Financial Market, and Banking & Insurance. After completion of B.Com, you can apply in any organisation for the post of accountant. Every company requires the accountant to keep track of the profit and loss of their company. One must have knowledge in areas like Basic Principles of Accountancy, Cost Accounting and Management Accounting to be an accountant. Other than an accountant, there are many career options in this field. Apart from a job, you can go to CA as CA's are highly paid in India. You can also go for MBA-Finance. After MBA you can get job offers like Analyst, Consultant, Relationship Manager and Investment manager.
