On the other hand you could go with the soundbite argument, "Just as the best time to plant a tree was ten years ago, the same is true of drilling an oil well".
Whatev, here's Marginal Revolution:
What are the benefits? Kotchen and Burger estimated that the oil had a value of $374 billion (writing in July 2007, they assumed a long-term price of $53/barrel), but that it would cost $123 billion to extract and market. The net return of $254 billion is divided consists of industry rents of $90 billion, Alaska tax revenues of $37 billion, and Federal tax revenues of $124 billion.
Under the authors' understanding of incidence, consumers wouldn't benefit much at all because oil prices would not fall noticeably. Still, drilling makes economic sense if the loss of environmental amenities is valued at less than $1,141 a person (per American, not per Alaskan) and that was with a price of oil roughly half of today's price....
