本文主要講述現代金融學與行為金融學的區別，有大量的證據可以將現代金融學的觀點與行為金融學區分開來。雖然個人投資決策不是基於金錢和風險，而是考慮社會影響，但行為金融學強調並客觀化個人作為決策的主要組成部分(Curtis, 2004)。多年來，當羅伯特•席勒(Robert Shiller)在1993年表示“投資於投機性資產是一種社會活動”時，一些令人鼓舞的跡象將突破這些限制，但大量證據尚未得到探索。本篇論文 代寫文章由美國論文通AssignmentPass輔導網整理，供大家參考閱讀。
There are rafts of evidence that distinguish the modern perspective of finance from behavioral finance. While individuals do not take investing decisions based on the money and risks but consider social influences, behavioral finance emphasizes and objectified individual as the main component in decision making (Curtis, 2004). Over the years, there were encouraging signs that would break through the limitations when Robert Shiller in 1993 had stated that “Investing in speculative assets is a social activity” but a plethora of evidence has been unexplored.
On the other hand, the challenge remains within the purview of behavioral finance as it fails to explain the individual acts and the decisions that converge to aggregate outcomes. It can be said that behavioral finance has limited predicted power and contradictory implications and it fails to provide aviable alternative to the theories that it criticizes. However, the research works have revealed that behavioral finance is still dependent on the ideologies of traditional economics and finance but is at odds with the modern perspectives of finance.
Harry Markowitz developed and propounded the Modern Portfolio Theory (MPT) published in the Journal of Finance in 1952 under the essay “Portfolio Selection”. The MPT is considered to be one of the most influential economic theories in the field of finance and investment. The modern portfolio theory is also referred to the mean-variance analysis. The fundamental of the theory is based on the portfolio assets in which the expected return is maximized for a specified level of risk. The risk in the mathematical framework is termed as variance. The theory suggests that the return and risk of an asset are not self-assessed but is based on the contribution of the overall risk and return of the entire portfolio. The theory is developed with the goal of fabricating a portfolio that is desired to maximize the expected returns which are consistent with the acceptable risk level. In this regards, Markowitz intended to measure and quantify the investment risk by the assessment of the variance of the return of an asset.
