This technique can provide some useful insights into the structure of...

Corporate managers who face both strategic uncertainty and market uncertainty confront a classic trade-off between commitment and flexibility. They can stake a claim by making a large capital investment today, influencing their rivals' behavior; or they can take a "wait and see" approach to...
