【摘要】：投資風(fēng)險與收益率二者的關(guān)系是經(jīng)濟(jì)投資中必須要慎重考慮的問題,也是經(jīng)濟(jì)學(xué)、管理學(xué)中爭論不休的問題。本文基于投資風(fēng)險與收益率的關(guān)系,展開了一系列真人實(shí)驗(yàn),并進(jìn)行了代理人模型模擬。得到了系統(tǒng)整體呈高風(fēng)險低收益的結(jié)果,即“波曼悖論”(Bowman Paradox)中提出的風(fēng)險收益負(fù)相關(guān)的趨勢。代理人模型結(jié)果還顯示出,代理人根據(jù)偏好不同明顯的分為兩組：始終偏好于選擇預(yù)期收益高的房間的代理人其風(fēng)險與收益呈顯著的線性正相關(guān),而其他代理人的風(fēng)險與收益則呈不顯著的線性負(fù)相關(guān)。本文繼續(xù)從理論分析方面入手,得到了相同的結(jié)論,并且證明了偏好對于風(fēng)險收益關(guān)系的影響。 本文繼續(xù)研究了所有代理人都用相同投資比例時,不同的投資比例對系統(tǒng)內(nèi)部代理人之間財富分布的影響。進(jìn)一步把投資比例引申為財富累積系數(shù),利用代理人模型,演繹了馬太效應(yīng)使貧富差距由小變大的過程。
[Abstract]:The relationship between investment risk and rate of return is an issue that must be carefully considered in economic investment, and it is also a controversial issue in economics and management. Based on the relationship between investment risk and rate of return, a series of real-action experiments are carried out, and agent models are simulated. The result that the whole system presents high risk and low return is obtained, that is, the trend of negative correlation of risk return proposed by Bowman Paradox in "Bowman Paradox". The results of the agent model also show that the agents are obviously divided into two groups according to their preferences: the agents who always prefer to choose the room with high expected returns have significant linear positive correlation between the risk and the return. However, the risk of other agents has no significant linear negative correlation with the return. In this paper, we get the same conclusion from theoretical analysis, and prove the influence of preference on risk-return relationship. In this paper, we continue to study the influence of different investment ratios on the distribution of wealth among agents in the system when all agents use the same investment ratio. Furthermore, the investment ratio is extended to the wealth accumulation coefficient, and the Matthew effect is used to deduce the process that the gap between the rich and the poor changes from small to large by using the agent model.
