a separate branch of economic and financial analysis which applies scientific research on human and social, cognitive and emotional factors to better understand economic decisions by consumers, borrowers, investors, and how they affect market prices, returns and the allocation of resources.Here are a couple of lecture series on this subject:
1. Russel James at the University of Georgia (via Farnam Street, and Simolean Sense)
2. Sanjay Bakshi's "Behavioral Finance and Business Valuation" class at MDI.
They are both quite fascinating, and present a great synthesis which make them worth a look even if you are familiar with many of the ideas.
