Estimation of firm value V and
volatility of firm value sV
• Usually, only the price of equity for most public firms is directly
observable, and in some cases, part of the debt is directly traded.
• Using option pricing approach:
equity value, E = f(V, sV, K, c, r)
volatility of equity, sE = g(V, sV, K, c, r)
where K denotes the leverage ratio in the capital structure, c is the
average coupon paid on the long-term debt, r is the riskfree rate.
• Solve for V and sE from the above 2 equations.
