Why is it so difficult to make accurate long-term economic forecasts for the world economy? There are many separate countries involved, each with a self-organizing economy made up of businesses, consumers, governments, and laws. These individual economies together create a single world economy, which again is self-organizing.
Self-organizing economies don’t work in a convenient linear pattern–in other words, in a way that makes it possible to make valid straight line predictions from the past. Instead, they work in ways that don’t match up well with standard projection techniques.
How do we forecast what lies ahead? Today, some economists believe that the economy of the United States is in danger of overheating. Others believe that Italy and the United Kingdom are facing dire problems, and that these problems could adversely affect the world economy. The world economy should be our highest concern because each country is dependent on a combination of imported and exported goods. The forecasting question becomes, “How will divergent economic results affect the world’s economy?”
I am not an economist; I am a retired actuary. I have spent years making forecasts within the insurance industry. These forecasts were financial in nature, so I have had hands-on experience with how various parts of the financial system work. I was one of the people who correctly forecast the Great Recession. I also wrote the frequently cited academic article, Oil Supply Limits and the Continuing Financial Crisis, which points out the connection between the Great Recession and oil limits.
Today’s indications seem to suggest that an even more major recession than the Great Recession may strike in the not too distant future. Why should this be the case? Am I imagining problems where none exist?
The next ten sections provide an introduction to how the world’s self-organizing economy seems to operate.
 The economy is one of many self-organized systems that grow. All are governed by the laws of physics. All use energy in their operation.
