Reaching the End of Early Stimulus – What’s Ahead?

Posted on by

Many people thought that COVID-19 would be gone with a short shutdown. They also thought that the world’s economic problems could be cured with a six month “dose” of stimulus.

It is increasingly clear that neither of these assumptions is correct. Despite the claims of epidemiologists, our best efforts have never been able to reduce the number of newly reported COVID-19 cases for the world as a whole for any significant period of time. In fact, the latest week seems to be the highest week so far.

At the same time, the economy, despite all of the stimulus, is not doing very well. Airlines are doing very poorly. The parts of the economy that are dependent upon tourism are having huge problems. This reduces the “upside” of economic recovery, pretty much everywhere, until it can be corrected. Continue reading →

COVID-19 and the economy: Where do we go from here?

Posted on by

The COVID-19 story keeps developing. At first, everyone listened to epidemiologists telling us that a great deal of social distancing, and even the closing down of economies, would be helpful. After trying these things, we ended up with a huge number of people out of work and protests everywhere. We discovered the models that were provided were not very predictive. We are also finding that a V-shaped recovery is not possible.

Now, we need to figure out what actions to take next. How vigorously should we be fighting COVID-19? The story is more complex than most people understand. These are some of the issues I see:

Scientific Models and Myths: What Is the Difference?

Posted on by

Most people seem to think, “The difference between models and myths is that models are scientific, and myths are the conjectures of primitive people who do not have access to scientific thinking and computers. With scientific models, we have moved far beyond myths.” It seems to me that the truth is quite different from this.

History shows a repeated pattern of overshoot and collapse. William Catton wrote about this issue in his highly acclaimed 1980 book, Overshoot.

What politicians, economists, and academic book publishers would like us to believe is that the world is full of limitless possibilities. World population can continue to rise. World leaders are in charge. Our big problem, if we believe today’s models, is that humans are consuming fossil fuel at too high a rate. If we cannot quickly transition to a low carbon economy, perhaps based on wind, solar and hydroelectric, the climate will change uncontrollably. The problem will then be all our fault. The story, supposedly based on scientific models, has almost become a new religion.

Recession Ahead: An Overview of Our Predicament

Posted on by

Many people have the impression that recessions come from financial missteps, such as the US subprime loan fiasco. If energy is involved at all, the problem comes from high oil prices as supply becomes inadequate to meet demand.

The real situation is different. We already seem to be on the road toward a new crisis; this crisis is likely to be much worse than the Great Recession of 2008-2009. This time, a major problem is likely to be energy prices that are too low for producers. Last time, a major problem was oil prices that were too high for consumers. The problem is different, but it is in some ways symmetric.

Last time, the United States seemed to be the epicenter; this time, my analysis indicates China is likely to be the epicenter. Last time, the world economy was coming off a high growth period; this time, the world economy is already somewhat depressed, even before hitting headwinds. These differences, plus the strange physics-based way that the world economy is organized, explain why the outcome seems likely to be worse this time than in 2008-2009.

I recently explained what I see as happening in a presentation for actuaries: Recession Likely: Expect a Bend in Trend Lines. This post is based on this presentation, omitting the strictly insurance-related portions.

The true feasibility of moving away from fossil fuels

Posted on by

One of the great misconceptions of our time is the belief that we can move away from fossil fuels if we make suitable choices on fuels. In one view, we can make the transition to a low-energy economy powered by wind, water, and solar. In other versions, we might include some other energy sources, such as biofuels or nuclear, but the story is not very different.

The problem is the same regardless of what lower bound a person chooses: our economy is way too dependent on consuming an amount of energy that grows with each added human participant in the economy. This added energy is necessary because each person needs food, transportation, housing, and clothing, all of which are dependent upon energy consumption. The economy operates under the laws of physics, and history shows disturbing outcomes if energy consumption per capita declines.

There are a number of issues:

  • The impact of alternative energy sources is smaller than commonly believed.
  • When countries have reduced their energy consumption per capita by significant amounts, the results have been very unsatisfactory.
  • Energy consumption plays a bigger role in our lives than most of us imagine.
  • It seems likely that fossil fuels will leave us before we can leave them.
  • The timing of when fossil fuels will leave us seems to depend on when central banks lose their ability to stimulate the economy through lower interest rates.
  • If fossil fuels leave us, the result could be the collapse of financial systems and governments.

[1] Wind, water and solar provide only a small share of energy consumption today; any transition to the use of renewables alone would have huge repercussions.
