The book by George A. Akerlof and Robert J. Shiller “Animal Spirits, How Human Psychology Drives the Economy, and Why It Matters for Global Capitalism”  has inspired me to share with you these thoughts. John Maynard Keynes introduced the term “Animal spirits” in 1936 to describe the instincts, proclivities and emotions that ostensibly influence and guide human behavior in business and so impact the economic outcome and development. G. A. Akerlof and R. J. Shiller provide in this book evidence that contemporary theory of economics based on the hypotheses of efficient market and rational expectation fails to explain economic processes in the periods of global crises. They further develop the term of Animal Spirits seeking to explain the evolution of global economy in the periods of crises and depression and looking for the appropriate measures how to overcome the economic slump.

If one would start speaking about the dragon kings and black swans, many people would think that the one is talking about the fairy tales. But these terms are used then speaking about the events in the financial markets! Black swans are rare, but observable in the nature. Dragon kings are only observed in the fairy tales. So we would be amused if we would see the black swan with our own eyes, yet if we would see the dragon king we would be completely shocked. In nature these kinds of event are extremely rare and improbable, while in the financial markets we see these kind of events frequently enough. Bellow you can find a talk by Didier Sornette (taken from ted.com, some of the related info is available from blog.ted.com), who talks about these kind of events, their impact and possibilities to predict.

One and half year ago world media exclaimed – finance is controled by a single super-corporation (e.g., read article in Lithuanian or English)! Evidently this conclusion is somewhat far fetched, yet it does capture one of the essential points of the underlying scientific research. The research actually shows that a comparatively small number of corporations control almost everything. Now you can listen to the one of the related researchers speaking about this discovery and hear him explain that does this actually mean. Continue reading “James B. Glattfelder: Who controls the world?” »
The most active and well known scientists contributing towards FuturICT project have organized their ideas into few articles, which discuss the current situation in contemporary complex social system modeling. These articles we published in a special issue of “The European Physical Journal Special Topics”. Most of the articles are available for free, thus we invite you to familiarize yourselves with them.
Recently on my Facebook news feed I found one article, which was rather interesting. “Teaching mathematics differently?” – ironical thought crossed my mind, while at the same time recalling some stand up comedians telling “wild” stories about the problem-based learning. It is truly funny to hear that children nowadays are forced to help the squirrel to count the nuts! Or to solve another default setup: “10 apples + 4 pears = 48 Litas, while 5 apples + 6 pears = 32 Litas, if so then how many Litas does a single apple or pear cost?” Why should anyone solve this problem in this way? Can’t the client just look up the price tags? Or check his receipt? Continue reading “Teaching math in a different way” »
Econophysics is not a very well known interdisciplinary field of research in Lithuania. There are very few Lithuania based scientists who are related to this very young and rapidly developing branch of Physics. Therefore we, being ones of the few, feel an obligation to introduce Econophysics to the other scientists, businessmen and the whole broader society. In this text we will discuss the basic ideas, current trends and the most common problems relevant to the field of Econophysics.
The name of Econophysics implies the application of physics, mostly the methods taken from Statistical Physics, to the Economics. Though until recently most of the econophysicists used to focus on the financial markets. Currently the field is expanding very rapidly and now concerns something more than just regular Economics or Finance – many physicists now attempt to tackle problems in the other social sciences. For these broader approaches there are other overlapping terms including Sociophysics, Physics of Risk, Physics of Socio-Economic Systems and other.
At this point we would like to stop the discussion on the use of the terminology. Recall that the aim of this text is somewhat different from that. We aim to familiarize you with the Econophysics! Continue reading “Vygintas Gontis: Econophysics – brand new outlook into social sciences” »
