Based on a critique on econometric and DSGE models (in particular in the context of the financial crisis), Doyne Farmer presents his current research programme that aims at building an agent-based model of the financial and economic crisis. It models heterogeneous agents and from there simulates the economy, firstly for the housing market. The interview gives a short insight in the research programme.

an interactive guide to the game theory of why & how we trust each other

When we have to make a decision, we consider all the pros and cons, try to gather a lot of information and estimate what consequences this decision might have. And then we make an (at least somewhat) rational decision. Or do we?

The most successful multialternative theories of decision making assume that people consider individual aspects of a choice and proceed via a process of elimination. Amos Tversky was one of the pioneers of this field, but modern decision theorists – most notably Neil Stewart – have moved things forward. At the current stage the theories are able to explain a number of strictly ‘irrational’ but reasonable quirks of human decision making, including various heuristics and biases. Not only this, but eye movements of participants strongly imply that the decision-making process depicted in the theories is an accurate one.

Organisationsbildung setzt eine Erkennungsregel voraus, die erlaubt festzustellen, welche Handlungen und unter welchen Aspekten sie als Entscheidungen der Organisation zu gelten haben. Diese Erkenntnisregel ist zunächst und vor allem eine Mitgliedschaftsregel.
