Standard economics lonely is not able to answer a lot of various questions that we face today. So to solve these kinds of problems non-disciplinary approaches have been produced to answer these questions that a discipline lonely is not able to answer them. In This research first we review the whole Non-disciplinary approaches and then we discuss economic psychology as a cross-disciplinary approach. By study of this approach we can achieve new indexes that had not been studied in standard economics so far and use subjective utility to compute utility of friendship, self esteem and respect that were not attended in standard economics up to now. Also we would present Quantitative methods to account welfare carefully.
