- A recent post (930122.1658) touched on the subject of economics. This is
- surely an area in which PCT can be useful. But it's not easy. Recent
- discussions have found the number of degrees of freedom involved with
- control of finger-hand-arm systems to be very large when broken down into
- the smallest pieces. US Economics involves some 250 million individual
- hierarchical control systems -- degrees of freedom? WOW!
-
- In the early 60's I, together with five other Radiological Physicists, had
- formed Radiation Control, Inc. One of their wives was a widely recognized
- economist, leading to an opportunity to raise questions about negative
- feedback systems in economic theory. I was told this was a familiar set
- of concepts, resulting in the development of large arrays of interacting
- systems, including both positive and negative feedback as well as
- cross-coupling. It is my impression that current economic models are
- derived from these concepts. But they don't seem to work very well.
- Perhaps the hierarchical concept needs to be added somewhere. Or maybe
- individual motivations, knowledge and skills should be included. A BIG
- JOB!
-
- I think it was in the early 70's -- I was with Mosler Safe as Manager of
- Applied Research -- I ran across "Industrial Dynamics," Jay W Forrester,
- MIT Press, Fourth Printing, 1965. This book traces a series of decisions
- made by a generalized manufacturing company resulting in oscillation due
- to mismanaged temporal variables -- not conflict. He discusses several
- interesting topics, but his major work consists of detailed digitized
- treatment of the resulting interactions. When I finally worked my way
- through the details, I realized that it could have been greatly simplified
- by using the standard second order differential equation and its
- solutions. This kind of thing could be revised and up-dated to good
- advantage. Once again, application of the hierarchical concept would
- surely be very helpful.
-
- In this connection, a column in the Wall Street Journal seems worth
- quoting.
-
- "In other words, those who haven't learned the mistakes of the past are
- about to repeat them. The Clinton administration seems poised to embark
- on yet another high-tax austerity program that will neither move the
- economy toward 4% growth nor substantially narrow the deficit.
-
- "Throughout economic history this truth remains: When something is taxed
- more, we get less of it. When income, investment and sales are taxed
- more, we have less of them. When after-tax rewards are reduced,
- productivity and risk-taking diminish. When retail items are taxed more
- (including gasoline), fewer sales result. When the cost of doing business
- rises, profits decline, along with output and employment." The Deficit
- Obsession, Lawrence A Kudlow (Chief Economist at Bear Stearns.) Wall
- Street Journal, Monday, January 25, 1993, p A14.
-
- Projects such as these directly involve working with higher order systems,
- particularly Sixth Order and its Modes. Many of these studies are needed.
