3. The parameters of a GARCH(1,1) model are estimated as ω = 0.000004, α = 0.05, and β = 0.92. What is the long-run average volatility and what is the equation describing the way that the variance rate reverts to its long-run average? If the current volatility is 20% per year, what is the expected volatility in 20 days?

3.  3: Stocks and Their Valuation: Corporate Valuation Model The recognition that dividends are dependent on earnings, so a reliable dividend forecast is based on an underlying forecast of the firm's future sales, costs and capital requirements, has led to an alternative stock valuation approach, known as the corporate valuation model. The market value of a firm is equal to the present value of its expected future free cash flows plus the market value of its non-operating assets: Free cash flows...

SOME DRAWBACK OF BLACK-SCHOLES Briefly discuss here some difficulties associated with the Black Scholes formula, which is widely used to calculate the price of an option. For example, consider a European call option for a stock. This is the right to buy a specific number of shares of a specific stock on a specific date in the future, at a specific price (the exercise price, also called the strike price). If all these quantities are fixed, the question becomes: what...
