Most people expect that our signal of an impending reduction in world oil or coal production will be high prices. Looking at historical data (for example, this post and this post), this is precisely the opposite of the correct price signal. Oil and coal supplies decline because prices fall too low for producers. These producers make voluntary cutbacks because the prices they receive fall below their cost of production. There often are supply gluts at the same time.
This strange situation arises because prices must be high enough for the producers at the same time that goods and services made by oil (and other energy products) are inexpensive enough for consumers to afford. There is a two way battle taking place:
(1) Prices producers require tend to rise over time, because of depletion. The easiest to extract portion of any resource (such as oil, coal, copper, or lithium) tends to be removed first. What is left tends to be deeper, lower quality, or otherwise more difficult to extract cheaply.
(2) Prices consumers can afford for discretionary goods (such as cell phones and automobiles) tend to fall for a combination of reasons:
- Wages of many workers fall because of competition from lower cost labor in other countries.
- Some jobs are eliminated through the use of computers or robots.
- Young people are increasingly being required to pay for higher education (beyond that which is provided free), leaving many with loans to repay, reducing their discretionary income.
- Changes to US healthcare law (mostly starting January 1, 2014) lead to required health insurance premiums. While some citizens find cost savings in this approach, healthy young people often experience cutbacks in discretionary income as a result.
- Rents and home prices keep rising faster than incomes.
When the discretionary income of the many non-elite workers of the world falls, they buy fewer finished goods and services. Finished goods and services are manufactured using commodities of many kinds, including oil, coal, copper, iron ore, and fresh water. When discretionary demand falls, commodity prices tend to fall. This is the problem we are encountering now. It tends to cause the prices of many commodities to fall below the cost of production. Eventually, producers decide to quit because production is no longer profitable. This is the issue that leads to peak oil, coal or copper.
