Discounted cash flow models are powerful, but they do have shortcomings. DCF is merely a mechanical valuation tool, which makes it subject to the axiom "garbage in, garbage out." Small changes in inputs can result in large changes in the value of a company. Instead of trying to project the cash flows to infinity, terminal value techniques are often used. A simple annuity is used to estimate the terminal value past 10 years, for example. This is done because it is harder to come to a realistic estimate of the cash flows as time goes on.
When the cross elasticity of demand for product A relative to the change in the price of product B is negative, it means that the quantity demanded of A has decreased relative to an increase in the price of product B. An increase in the price of B will reduce the quantity demanded of A.
