For those who will only read the first two paragraphs up on this posting let me note the big links and the big arguments. The most prominent worrier is Timothy Geithner, President of the New York Federal Reserve Bank, who gave a speech recently at the Hong Kong Monetary Authority. It is entitled “Hedge funds and derivatives and their implications for the financial system” . The cover story of latest issue of The Economist, “The Dark Side of Debt,” also deals with this matter, although mostly retaining a pollyanna view. A heavy theoretical paper showing the underlying problem is by William A. Brock, Cars Hommes, and Florian Wagener, “More hedging instruments may destabilize markets” CeNDEF Working paper 06-12, University of Amsterdam . The title says it all. And the recent data on the explosion of options and derivatives has simply not been realized by most observers, to pick one: credit derivatives, almost nonexistent in 2000, zoomed from $19 trillion to $26 trillion during the first six months of this year alone. We are in the midst of an unprecedented transformation of the world financial system that is way beyond the ability of the regulatory authorities to do anything about except to lose sleep at night, as apparently Geithner is doing. I don’t blame him at all.
Also:
The conference on econophysics, officially “Physics and Socio-Economic Phenomena” was part of the International School of Complexity at the Ettore Majorana Center for Scientific Culture, this year being the centennial of the birth of Majorana, the first to propose the neutron and the neutrino and who disappeared mysteriously in 1938 (and also wrote a paper proposing what is now called econophysics). Some heavies at this one were Rosario Mantegna, coinventor of the term “econophysics,” some folks from Bouchaud’s shop, and Mauro Gallegati of Ancona. I gave the first lecture, “Debating the Role of Econophysics,” which is up on my website.
