an economic theory of limited oil supply

Oil as a percent of total 2006 energy consumption for European countries, based on BP’s 2012 Statistical Review of World Energy

ourfiniteworld | We seem to hear two versions of the story of limited oil supply:

1. The economists’ view, saying that the issue is a simple problem of supply and demand. Substitution, higher prices, demand destruction, greater efficiency, and increased production of oil at higher prices will save the day.

2. A version of Hubbert’s peak oil theory, saying that world oil production will rise and at some point reach a plateau and begin to decline, because of geological depletion. The common belief is that the rate of decline will be determined by geological considerations, and will roughly match the rate at which production increased.

In my view, neither of these views is correct. My view is a third view:

3. An adequate supply of cheap ($20 or $30 barrel) oil is no longer available, because most of the “easy to extract” oil is gone. The cost of extracting oil keeps rising, but the ability of oil-importing economies to pay for this oil does not. There are no good low-cost substitutes for oil, so substitution is very limited and will continue to be very limited. The big oil-importing economies are already finding themselves in poor financial condition, as higher oil prices lead to cutbacks in discretionary spending and layoffs in discretionary industries.

The government is caught up in this, as layoffs lead to more need for stimulus funds and for payments to unemployed workers, at the same time that tax revenue is reduced. There can be a temporary drop in oil prices (as there was in late 2008), as recession worsens, but eventually demand rises again, oil prices rise again, and the pattern of layoffs and increased governments financial problems occurs again.

Without substitutes at a price that the economy can afford, economies will adapt to lower amounts of oil they can afford by worsening recession, debt defaults, and reduced international trade. There may be tendency for international alliances (such as the Euro) to fall apart, for countries to break into smaller units (Catalonia secede from Spain, or countries break up the way the Soviet Union and Yugoslavia did).

At some point, probably not too many years in the future, the amount of oil extracted from the ground will drop, reflecting a combination of geological and economic factors. The fall may very well be quite steep. While we can’t expect to extract more than geology will allow, there is nothing to say that political and economic factors will allow extraction of this amount. If civil war breaks out in an oil producer, production may drop quickly. Or if oil prices drop because of severe recession, drilling of new fields and wells may drop off quickly, leading to lower production as existing wells deplete, and not enough new supply as added. There may also be disruption in international sales of oil.
