THE SHORT VERSION

Real Options, explained.

A real option is a valuable ability to make a future operational or investment choice, rather than an obligation to commit immediately.

01 / THE MECHANISM

Why it happens

Build now for 50 and receive 100 or 20 at time one, discounting at 10%. Alternatively pay a fee now, observe demand at time one and build only when the immediate payoff exceeds 50. Expected waiting value is p×50/1.1−fee, while immediate NPV is (100p+20(1−p))/1.1−50.

A real option is a valuable ability to make a future operational or investment choice, rather than an obligation to commit immediately.

Read the result

Compare expected discounted payoffs before committing, then keep the realised payoff separate. Waiting preserves a contingent decision but has its own fee and timing assumptions.

02 / FOLLOW IT THROUGH

A worked example

A project whose demand will become known

  1. At fifty-percent high demand and fee five, immediate-build NPV is about 4.55 under a ten-percent discount rate.

  2. Compare waiting, which builds only after high demand and has expected value about 17.73 under the model's instant time-one construction rule.

  3. Increase the waiting fee to twenty and recompute before choosing. Flexibility has a price rather than an unconditional advantage.

OPTIONAL DEEPER DETAILGo deeper: inside the model

Inside this model

Build now for 50 and receive 100 or 20 at time one, discounting at 10%. Alternatively pay a fee now, observe demand at time one and build only when the immediate payoff exceeds 50. Expected waiting value is p×50/1.1−fee, while immediate NPV is (100p+20(1−p))/1.1−50.

03 / BEYOND THE EXPERIMENT

Where this idea is useful

A practical use

Preserving a reversible next step can be valuable when information will arrive before a large irreversible commitment.

CHECK YOUR INTUITION

A common misconception

THE TEMPTING CONCLUSION

“More uncertainty makes postponing every decision best.”

THE MORE USEFUL DISTINCTION

Waiting can preserve options but also incur fees, lose opportunities or delay benefits. Its value depends on what will be learned and what actions remain feasible.

What this explanation leaves out

  • The waiting branch assumes instant construction and payoff after information arrives, without competition or expiry. Teaching amounts do not value a real company or constitute investment guidance; waiting also carries an explicit cost.
ONE MORE QUESTION

Why is the waiting payoff different from building now?

The waiting branch pays construction cost at time one only after seeing demand, and receives the payoff immediately then. That strong assumption is explicitly part of the teaching model.

TAKE THE IDEA WITH YOU

What information will arrive before a commitment, and what would it cost to keep the choice open until then?
