New IMF Working Paper Models Impact Of Oil Limits On The Economy

Our Finite World

11 May, 2012

The International Monetary Fund (IMF) recently issued a new working paper called “The Future of Oil: Geology versus Technology” (free PDF), which should be of interest to people who are following “peak oil” issues. This is a research paper that is being published to elicit comments and debate; it does not necessarily represent IMF views or policy.

The paper considers two different approaches for modeling future oil supply:

1. The economic/technological approach, used by the US Energy Information Administration (EIA) and others, and

2. The geological view, used in peak oil forecasts, such as forecasts made by Colin Campbell and forecasts made using Hubbert Linearization.

The analysis in the IMF Working Paper shows that neither approach has worked perfectly, but in recent years, forecasts of oil supply using the geological view have tended to be closer than those using the economic/technological approach. Since neither model works perfectly, the new paper takes a middle ground: it sets up a model of oil supply where the amount of oil produced is influenced by a combination of (1) geological depletion and (2) price levels.

This blended model fits recent production amounts and recent price trends far better than traditional models. The forecasts it gives are concerning though. The new model indicates that (1) oil supply in the future will not rise nearly as rapidly as in the pre-2005 period and (2) oil prices are likely to nearly double in “real” (inflation-adjusted) terms by 2020. The world economy will be in uncharted territory if this happens.

It seems to me that this new model is a real step forward in looking at oil supply and the economy. The model, as it is today, points out a definite problem area (namely, the likelihood of oil high prices, if growth in oil production continues to be constrained below pre-2005 rates of increase). The researchers also raise good questions for further analysis.

At the same time, I am doubtful that the world GDP forecast of the new model is really right–it seems too high. The questions the authors raise point in this direction as well. Below the fold, I discuss the model, its indications, and some shortcomings I see. More
