Financial markets have been behaving in a very turbulent manner in the last couple of months. The issue, as I see it, is that the world economy is gradually changing from a growth mode to a mode of shrinkage. This is something like a ship changing course, from going in one direction to going in reverse. The system acts as if the brakes are being very forcefully applied, and reaction of the economy is to almost shake.

What seems to be happening is that the world economy is reaching Limits to Growth, as predicted in the computer simulations modeled in the 1972 book, The Limits to Growth. In fact, the base model of that set of simulations indicated that peak industrial output per capita might be reached right about now. Peak food per capita might be reached about the same time. I have added a dotted line to the forecast from this model, indicating where the economy seems to be in 2019, relative to the base model.

The economy is a self-organizing structure that operates under the laws of physics. Many people have thought that when the world economy reaches limits, the limits would be of the form of high prices and “running out” of oil. This represents an overly simple understanding of how the system works. What we should really expect, and in fact, what we are now beginning to see, is production cuts in finished goods made by the industrial system, such as cell phones and automobiles, because of affordability issues. Indirectly, these affordability issues lead to low commodity prices and low profitability for commodity producers. For example:

  • The sale of Chinese private passenger vehicles for the year of 2018 through November is down by 2.8%, with November sales off by 16.1%. Most analysts are forecasting this trend of contracting sales to continue into 2019. Lower sales seem to reflect affordability issues.
  • Saudi Arabia plans to cut oil production by 800,000 barrels per day from the November 2018 level, to try to raise oil prices. Profits are too low at current prices.
  • Coal is reported not to have an economic future in Australia, partly because of competition from subsidized renewables and partly because China and India want to prop up the prices of coal from their own coal mines.

The Significance of Trump’s Tariffs

If a person looks at history, it becomes clear that tariffs are a standard response to a problem of shrinking food or industrial output per capita. Tariffs were put in place in the 1920s in the time leading up to the Great Depression, and were investigated after the Panic of 1857, which seems to have indirectly led to the US Civil War.

Whenever an economy produces less industrial or food output per capita there is an allocation problem: who gets cut off from buying output similar to the amount that they previously purchased? Tariffs are a standard way that a relatively strong economy tries to gain an advantage over weaker economies. Tariffs are intended to help the citizens of the strong economy maintain their previous quantity of goods and services, even as other economies are forced to get along with less.

I see Trump’s trade policies primarily as evidence of an underlying problem, namely, the falling affordability of goods and services for a major segment of the population. Thus, Trump’s tariffs are one of the pieces of evidence that lead me to believe that the world economy is reaching Limits to Growth.

The Nature of World Economic Growth

Economic growth seems to require growth in three dimensions (a) Complexity, (b) Debt Bubble, and (c) Use of Resources. Today, the world economy seems to be reaching limits in all three of these dimensions (Figure 2).

Complexity involves adding more technology, more international trade and more specialization. Its downside is that it indirectly tends to reduce affordability of finished end products because of growing wage disparity; many non-elite workers have wages that are too low to afford very much of the output of the economy. As more complexity is added, wage disparity tends to increase. International wage competition makes the situation worse.

A growing debt bubble can help keep commodity prices up because a rising amount of debt can indirectly provide more demand for goods and services. For example, if there is growing debt, it can be used to buy homes, cars, and vacation travel, all of which require oil and other energy consumption.

If debt levels become too high, or if regulators decide to raise short-term interest rates as a method of slowing the economy, the debt bubble is in danger of collapsing. A collapsing debt bubble tends to lead to recession and falling commodity prices. Commodity prices fell dramatically in the second half of 2008. Prices now seem to be headed downward again, starting in October 2018.

Even the relatively slow recent rise in short-term interest rates (Figure 4) seems to be producing a decrease in oil prices (Figure 3) in a way that a person might expect from a debt bubble collapse. The sale of US Quantitative Easing assets at the same time that interest rates have been rising no doubt adds to the problem of falling oil prices and volatile stock markets. The gray bars in Figure 4 indicate recessions.

Growing use of resources becomes increasingly problematic for two reasons. One is population growth. As population rises, the economy needs more food to feed the growing population. This leads to the need for more complexity (irrigation, better seed, fertilizer, world trade) to feed the growing world population.

The other problem with growing use of resources is diminishing returns, leading to the rising cost of extracting commodities over time. Diminishing returns occur because producers tend to extract the cheapest to extract commodities first, leaving in place the commodities requiring deeper wells or more processing. Even water has this difficulty. At times, desalination, at very high cost, is needed to obtain sufficient fresh water for a growing population.
