Lecture: Prof. Alan Kirman’s guest lecture

Professor (em.) ALAN KIRMAN (Université d’Aix-Marseille) will give a lecture on

“The crisis in economic theory”

Thursday, September 1st, 18:15 – 19:15.
Small Festival Hall (Pieni Juhlasali), University Main Building (Fabiankatu 33).

In this presentation I will discuss modern macroeconomic and financial models in the light of the current crisis. Theory has been revealed to be inadequate in its explanation of the origins and the nature of the crisis, as Jean-Claude Trichet the Governor of the European Central bank and his colleagues at other central banks have indicated. Basic macroeconomic models, however sophisticated have continued to be based on the same foundations shown to be wanting in the 1970s and financial market models have continued to use the « efficient markets hypothesis » despite warnings by numerous mathematicians and economists since 1900 as to its unsound foundations. I will not dwell on the details of standard macroeconomic models but will suggest some ways forward. We need to construct models, which may not be able to predict the timing of the onset of a crisis but will encompass the possibility of one. The most promising candidates for such models are those, which view the economy as a complex adaptive system, may use some of the tools of statistical physics and do not necessarily use the standard equilibrium approach. Such models put the interactions between individuals in the centre of the picture, and reveal how major changes in the states of the economy can result, as in many models in physics and in biology, from relatively minor changes in key parameters. Crises are a characteristic of the endogenous dynamics of the system and not the result of some unspecified exogenous shocks.

The visiting lecture is a part of the IX conference of the International Network of Economic Methodology (INEM 2011), but OPEN FOR ALL.
