In the BSM model, we cannot observe a firm;s asset value and volatility directly from the market, while for the KMV model, such figures could be obtained using current equity value.
在后面的讲义中说到merton模型和KMV模型中,资产价格都是用的Market Value,即equity-based data,为什么这里说“In the BSM model, we cannot observe a firm;s asset value and volatility directly from the market”? 请老师帮忙解答一下,我的理解是merton和KMV的资产价格都是从market value得到的,这样理解对吗?
