A presentation of methods for measuring the economic value of information in two different stopping environments. The decision process in the first environment is repetitive, while the associated probability mechanism is unknown. Some recent results of statistical decision theory are used to assess the value of collecting more information. Decision processes comprising the second class of stopping problems have a terminating structure. The decisionmaker is assumed to know the probability law that generates investment opportunities, but each successive investment opportunity entails additional investment costs. Dynamic programming determines when the best investment opportunity occurs. 37 pp. Bibliog.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
