Stanley - I want to know more about the relationship between psychology, banking and finance.
Saberi - Well, Stanley very few books or articles and research papers have been written on this. I recommend you do a thorough search using Google scholar. There's one recent book on the psychology of relationship banking and there are a few papers on customer loyalty, relationship, brand commitment and so on which you will get in any journal database. Very little work has been done on this but potentially a good area of research. Good luck with your search. Thanks!
