Quadrigram. Minority games. I have an essay just published in Bloomberg. The essay is quite short and I wanted to give interested readers a few more details and links to further reading on the subject: how to build simple yet plausible models of financial markets.
Hence, this post. Traditional models of markets in economics work from the idea of equilibrium. What happens in the market is assumed to reflect the interplay of two things: 1. the decisions of countless market participants who act more or less rationally in their best interests, their actions collectively bringing the market toward a balance in which stocks, bonds, or other instruments take their realistic "fundamental" values (or at least something close to those values), and 2. external shocks that hit the market in the form of new pieces of information concerning businesses, political events, changes in regulations, technological discoveries and so on.
So, how to build models that go beyond this equilibrium picture? So --what is the minority game? 1. Computers: Artificial Life: Artificial Worlds. Researchers solve biological mystery and boost artificial intelligence. By simulating 25,000 generations of evolution within computers, Cornell University engineering and robotics researchers have discovered why biological networks tend to be organized as modules – a finding that will lead to a deeper understanding of the evolution of complexity.
The new insight also will help evolve artificial intelligence, so robot brains can acquire the grace and cunning of animals. From brains to gene regulatory networks, many biological entities are organized into modules – dense clusters of interconnected parts within a complex network. For decades biologists have wanted to know why humans, bacteria and other organisms evolved in a modular fashion. Like engineers, nature builds things modularly by building and combining distinct parts, but that does not explain how such modularity evolved in the first place.
Renowned biologists Richard Dawkins, Günter P. "Once you add a cost for network connections, modules immediately appear. Statistica@Ning - La Comunità Italiana dedicata alla Statistica.

Da Wikipedia, l'enciclopedia libera. Le direzioni Le parti del corpo La notazione Laban è un sistema di notazione dei movimenti del corpo inventata nel 1928 da Rudolf Laban (1879-1958). Questo sistema è detto Labanotation negli Stati Uniti, Kinetography nel Regno Unito e cinétographie in Francia. Storia[modifica | modifica sorgente] Uno stesso segno indica: la direzione del movimento (avanti - indietro - sinistra - destra - diagonali - sul posto)l'altezza (alto - basso - intermedio. La posizione dei segni sul pentagramma da la simultaneità dei movimenti (lettura orizzontale) e la loro successione (lettura verticale).
Le distanze, le relazioni con i partner o con degli oggetti, il centro di gravità, la dinamica, le giravolte, i salti, le traiettorie ed il piazzamento al suolo, sono indicati da dei segni specifici.

Drucker - Spirit of an Organisation. This Southbeach model shows a perspective of Peter F. Drucker; "the man who invented management". The column on the left represents qualities of the people in an organisation, and on the right, we have the activities of the organisation itself. These two systems are inextricably interlocked and require each other in order to succeed. In Drucker's book, The Practice of Management, at the beginning of Chapter 13: The Spirit of an Organisation, he says: "Two sayings sum up the 'spirit of an organisation'.
One is the inscription on Andrew Carnegie's tombstone: Here lies a manwho knew how to enlist in his servicebetter men than himself The other is the slogan of the drive to find jobs for the physically handicapped: It's the abilities,not the disabilities,that count. Management by objectives tells a manager what they ought to do.
How can we create successful individuals?
