Chinese Abstract: CAPM 所在的资本市场是非完全的,并且是 一 个 Hilbert 空间,我们找出了该市场中 SDF 模仿支付的显式表达式。纯风险证券的局部均衡中,CAPM 公式成立,CAPM … 等价于市场组合恰好为切点组合,并且证券价格的通解在一维空间中。给定投资者的禀赋和均值方差偏好,结合 CAPM 的价格通解,资本市场的均衡条件转化为单变量的方程,从而求得均值方差均衡价格的解析解。证券价格是内生的,全体风险证券是作为 一 个整体被定价的,貌似真实的风险决定收益是局部均衡的产物,其错误在于把市场收益率当成外生的。我们还通过数值例子,分析均值方差决策与无套利的关系,化解不可能前沿的危机,展示贝塔定价导致欧式看涨期权负价格,以及不可以使用贝塔估计权益资本成本。CAPM …English Abstract: The capital market for CAPM is incomplete and is a Hilbert space, we find out the analytic expression …
