| Tóm tắt≠ | Real options valuation applies the theory of financial options to real (physical, strategic) investment decisions, valuing the managerial flexibility to defer, expand, contract, switch, or abandon a project as uncertainty resolves over time. Where standard discounted-cash-flow analysis assumes a now-or-never commitment to a fixed plan, real options recognize that managers hold rights — not obligations — to act, and that this flexibility has value precisely because the future is uncertain. Using option-pricing and dynamic-programming methods, the approach values these embedded options and identifies the optimal timing and conditions for exercising them. | Risk-neutral valuation (1979) is the fundamental principle that derivative prices equal the expected payoff discounted at the risk-free rate, computed under a risk-neutral probability measure (Q-measure). This principle, formalized by Harrison and Kreps, eliminates the need to estimate risk premia and is the foundation of modern derivatives pricing. |
