SHRP 2 L11: Final Appendices<br />

Comment #5:<br />

Real options is a specific branch of options evaluation. It does not concern financial assets, but<br />

rather other tangible assets in which the value of the option depends upon one or more contingent<br />

events. Examples are raising <strong>to</strong>lls at such time traffic volumes reach a certain level, investing in the<br />

next stage of drug development assuming preliminary drug trials are successful, pursuing a line of<br />

research once a positive feasibility determination has been made, and developing the next<br />

component of a modular electronics platform once the market for additional modules have been<br />

established. In each of these examples, the value is conditional upon an event occurring in the<br />

future or upon a condition state being realized. The term Real Options for the most part has a<br />

specific meaning among those who are expert in this branch of financial analysis. It is possible that<br />

the semantic elasticity of the term “real options” allows it <strong>to</strong> be applied <strong>to</strong> valuing travel time<br />

reliability. However, one of the country’s leading experts on Real Options we consulted does not<br />

think this approach is applicable <strong>to</strong> valuing travel time reliability:<br />

Response #5:<br />

The reviewer is correct that the common use of the term Real Options is in a capital budgeting<br />

context, and from the fact that this setting involves real (vs. financial) assets. Others, however, make<br />

the distinction between whether the option is purchased, or arises naturally in the course of decision<br />

making under uncertainty. Still others distinguish between whether the option is tradable or not.<br />

Since we know of no one else who has studied travel time reliability using the options approach, it is<br />

not clear what is the proper terminology <strong>to</strong> use. However, Professor Lenos Trigeorgis, a well-known<br />

expert in the field of real options analysis, applied the Real Options term in an analogous setting;<br />

i.e., a decision <strong>to</strong> increase flexibility of production processes as a defense against exchange rate<br />

variability. (In this case, value arose from increasing flexibility.)<br />
