Real options were once the solution to many investment decision and valuation problems. Julian Roche, having first explained in detail what real options are and how they are valued, then judiciously sets out the case for and against real options in a practical, investment environment. He tackles such questions as issues in delineating questions for real options to solve, how they are valued, who supports and uses them and why, what products are in the marketplace and how useful they are, and what the future holds for this once promising development in decision making and corporate finance. Essential reading for anyone genuinely interested in this somewhat arcane aspect of finance, this book really does show the real problems in real options.
