EMV(期望货币值)和EUV(期望效用值)是投资决策中常用的两种方法。期望货币值客观分析几种情况出现的收益或亏损值,及可能出现的概率,计算期望值,进行方案决策,但是它没能体现投资者(决策人)的价值观、偏好、经济承受能力。期望效用值准则是决策者在确定环境下对每个方案的隐含价值或偏好的一种量度,正好补充了期望货币值的不足,两者结合能够取长补短,达到更符合实际的决策方案。
EMV (Expected Currency Value) and EUV (Expected Utility Value) are two common methods used in investment decisions. Expectations Monetary values Objectively analyze the return or loss in several situations, the probability of occurrence, the calculation of expected value, and the decision-making of the program. However, it does not reflect the values, preferences and affordability of investors (decision makers). The expected utility value criterion is a measure of the implied value or preference of decision-makers in each environment in a certain environment, which exactly complements the lack of desired monetary value. The combination of the two can complement each other and achieve a more realistic decision-making plan.
