Dissertations / (consumer behaviour / rural India) Need suggestions on topics for my PhD [2]

Hi,

I am from India. I was working in the financial services sector (stock broking/wealth management) for over 8 years. Moved into academics a year ago. My area of interest is marketing and the industry i want to focus on is financial services/banking since i have fair knowledge about the same. Can anyone please guide/suggest me a specific topic? I was thinking about consumer behaviour and preferences towards investments in rural India. Please provide some valuable insights.

Regards,
Alok Chhajer
