    Assets, Demographics and the Kondratieff Cycle

In the 1970s I first began making computer models to udnerstand and predict economic events for businesses. Although I had not started with any idea that cycles were a way to do this, cycles in the data jumped out and showed me that this was the way to understanding what was happening. As well as a number of shorter cycles in the range of 3 to 9 years in period, there was one very long cycle of about 50 years which was my entire time-series span. When I began to read the literature on cycles I found that these cycles had all been discovered before and were generally given names of the discoverers. The long cycle was called the Kondratieff cycle after its discoverer in the 1920s, although there had been some prior mentions of it. The period is often given as 54 years. There is a weather / climate cycle given as 53 years by another Russian, Chizhevsky and we may consider that climate plays some part in driving the cycle.

Using that cycle I was able to make much more accurate predictions than the NZ (New Zealand – where I live) government and economists. In particular I recognized that the high unemployment and other serious conditions that had being going on from 1974 to 1978 would continue for some substantial time longer than economist said.

At that time I realized that the Kondratieff cycle was not just a cycle in prices (or in weather) as had previously been recognized. It was also a cycle in demographics. Here is an article that I wrote some years back – The Cause of the Kondratieff Cycle. This had been my understanding from the 1970s until recently. I won’t quote that whole article here, but people are most welcome to quote parts of it here if they have comments or questions.

It has always been my view that economists and governments paid far too little attention to demographics. The fluctuations in birth rates quite clearly follow the Kondratief cycle. There were low birth rates in the 1930s and 1970s-1980s when depressions occrred. There were high birth rates in the early 1900s and 1950s when healthier economies prevailed. The birth rate has picked up a little over the last decade or so as predicted. We need to be aware that this is superimposed on a generally declining birth rate due to better education and longer life expectancy and especially reduced infant mortality.

I have not been expecting the next Kondratieff wave downturn for another 20 years based on the previous two with multiples of 53 years added to them. My main focus has been on the difficulty of absorbing demographic lumps into the workforce, of providing them with homes and essential services because these things draw existing production away from consumption to capital stock production. I was always aware that dependant population of children and the retired were centred approximately one Kondratieff cycle apart so that the two dependencies hit peaks together.

Chris Martenson has emphasized the lump passing into retirement as very important. Many people have realized that this is a problem with no easy solutions. However until now I had always thought that the next depression would be caused by the next birth rate lump coming along which is a long way off still.

    Re: Assets, Demographics and the Kondratieff Cycle

What is the correlation before the twentieth century? Are there any statistics on that?

Cycles are typical of linear dynamical systems, but it would suprise me if such systems accurately described our economy.

I don’t have enough data before the twentieth century to answer that.

There are strongly significant cycles found in all long time series studied. That includes economics, commodities, animal populations, weather, history, wars, etc etc etc I recommend Edward Dewey’s "The Case for Cycles" as an excellent overview of the subject. http://www.cyclesresearchinstitute.org/dewey/case_for_cycles.pdf

Ray –

I find it interesting that some of the Kondratieff cycle intervals are also fibonacci retracement values AND fibonacci primes.

Now I am curious to see if applying Kepler’s limit of consecutive quotients to the Kondratieff values also converged on the golden ratio.

This is just what my bible code comment was all about: maybe any time series shows evidence of cyclic beviour on the short run. That just doesn’t mean anything.

I think that the fibonacci retracements is a myth. I am willing to see actual evidence to the contrary, but my own analysis shows that markets retrace by pretty random proportions.

I am not referring to short term random movements loking like a cycle for a wee while. A cycle is not considered real unless it passes a proper statistical test, the Bartell’s test.

I recommend you to read Edward Dewey’s "The Case for Cycles" which is solid science.

If you want to debate on the basis of facts then please do so. If you only want to do name calling, then go somewhere else as I have no interest in people that do that.

I wasn’t talking about the market at all.  I was talking about the value of the retracement percentages – not applying it to anything in particular.

But  you would be surprised what you would come up with if you looked at price-time performance intervals – up AND down.  Especially around the 34, 55 and 233 minute intervals.

I would like to see a computer analysis with lots of data. Then I would believe it.

    Re: Assets, Demographics and the Kondratieff Cycle

Ray. Can you describe your research with an abstract perhaps?

Formal research is part of my bread and butter (what I do for a living) and my interest in your claims has definitely piqued.

This sort of stuff, for me at least, is fascinating.

Thanks.

Here’s an interesting angle. Have you tried evaluating price movement using Fourier or Wavelet analysis?
