If you are considering pursuing higher education in engineering, it's important to choose a college with experienced and highly qualified faculty. When it comes to DAVIET and DAVU, here are some things to consider:

• DAVIET, or the DAV Institute of Engineering and Technology, is a well-established engineering college located in Jalandhar, Punjab. DAV University is a newer university that also offers engineering programs.
• One advantage of DAVIET over DAV University is that it has more experienced and better faculty. DAVIET's faculty members have years of teaching and research experience, and many of them have published research papers in reputed journals.
• On the other hand, the faculty at DAVU may not be highly qualified. Most of them have completed their M.Tech without decent research publications and are not capable of guiding students in research. This may not be the case for all faculty members at DAVU, but it's important to do your research and assess the faculty's qualifications before making a decision.
• The management at DAVU is pathetic. It's important to research the college or university's management and assess whether they are supportive of students and committed to providing a good education.
• Another consideration is the location of the college or university. DAV University is far away from the city. This may make it more difficult to access resources and opportunities outside of the college or university.
• There is no job guarantee at DAVU. While this may not be the case for all colleges or universities, it's important to research the college or university's placement record and assess whether they have a good track record of helping students find employment after graduation.

DAVIET may be a better option than DAV University due to its more experienced and qualified faculty, better management, and overall positive learning environment. However, it's important to do your own research and assess whether DAVIET or any other college or university is the right fit for you based on your academic and personal goals. 

Ph.D. is different from other degrees in which you learn and take exams. During your Ph.D. you need a research guide who takes an interest in your work and is involved in active research in the same field as you.

Unless your guide is active in research, they can not guide you. Here research refers to publishable research in good journals.

Your field of research will determine the better option out of the two to pursue your Ph.D. in Economics. If say, you wish to work on Marxism/Communism or related topics, CESP JNU is the right choice for you. You will find ample assistance in JNU.

If you wish to work in Micro Theory such as on Contract theory or Industrial Organization, DSE will be the right option. There are more faculty members in DSE than CITD JNU who work in these areas.

If you wish to work on DSGE literature ( Macro), the guide will exist as a formality and you will be on your own for the most part. This field of research is not pursued by most in India and you will mostly have to rely on yourself.

Also, if you wish to work in the corporate after your Ph.D. , join DSE as it offers very good placements. JNU does not offer on campus placements. The economics at JNU though, is very enriching. There you will be exposed to a variety of subjects, debates, etc. 

You must choose between JNU and DSE for your Ph.D. Economics, based on your personal preference and your field of research.

You should choose JNU for MA in Philosophy. It offers better learning opportunities. JNU is also the best economical choice. MA Philosophy from JNU costs only INR 654. 

JNU has wonderful History, Aesthetics, and Sociology department. This is an advantage if you want your Philosophy course to be thoroughly interdisciplinary. The residential university life of JNU is a unique learning experience in itself.
