Time-to-build investment and uncertainty in oligopoly

This paper examines how time to build alters strategic investment behaviour under oligopoly. Facing demand uncertainty, firms decide whether to invest early or wait until
uncertainty has been resolved. A game that captures time-to-build investment is contrasted with another one in which investment is quick in place. We show that a time lag between when and how much to invest reduces the incentive to delay. When investment requires time to complete, early investment occurs more to avoid becoming a follower than to become a strategic investment leader. The opposite is true with quick-in-place investment. A brief welfare analysis is provided.
