Economics

Very valid and possible confusion. These three are inter related as well as different. However, all three are non technical degrees, yet economics goes to social science area where you go for specialisation in some aspect or do research and post graduation, etc. In mass communication, which is also social science, you may specialise in technical areas like electronic media and film production, etc. You can stay in general mass communication aka journalism as well. The third is hotel management which is bit different from the other two. Hospitality jobs are huge in number but you need to take a call as you want to go to cooking or service jobs. Instant jobs are possible in hospitality than in mass communication and economics.

The career prospects for economics graduates are many. Numerous fields are waiting for economic graduates both in the public as well as the private sectors. In the government sector, one may try for Indian Economic Services, jobs in Reserve Bank of India, PSUs and other public sector banks. All these jobs have wonderful career options. These jobs give you social prestige along with financial stability. The private sector also offers jobs for economics graduates in the fields like private banks, MNCs, BPOs, KPOs, Business journals, and newspapers. A good opportunity is also waiting for economic students in higher education. One can pursue Ph.D in economics to enter into the field of teaching in colleges and universities.
One makes a successful career as a Corporate Lawyer after BA in economics followed by LLB. BA in economics and MBA placed one at a better position in the private sector. Economic Journalism is another shining area for job perspective.
