Behavioral Economics and Finance

Hi everyone, I hope you’re doing fine. I would appreciate any insights/thoughts on where is the optimal niche of finance for someone who base his/her investment thesis in “the application of sociology, psychology, and economics in finance”. (Or where/how can someone best develop this)

i.e. Guide the Investment strategy for the fund from a top-down approach

Determine which sectors of the economy will be benefited by analyzing monetary and fiscal policy, various macroeconomic indicators, and human behavior in response to the current context/environment (saving and spending).

Thanks in advance!
