Adaptive Präferenzen

March 1, 2014

Rainer Hank berichtet hier über Carl Christian von Weizsäckers Konzept der adaptiven Präferenzen (Symposion anläßlich Bertram Schefolds 70. Geburtstag). Prof. Weizsäckers Vortragsmanuskript gibt’s hier.

Menschen, die nicht schon als Ökonomen auf die Welt gekommen sind, fanden dieses Konzept der starren Präferenzen immer schon wunderlich und wenig plausibel. Der Alltagserfahrung viel näher kommt der Verdacht, dass Präferenzen sich ändern je nach Umgebung, in der wir gerade leben, oder nach der Rolle, die wir gerade spielen. Präferenzen befinden sich im Wettstreit nicht nur inter-, sondern auch innersubjektiv:  Der Gelegenheitsraucher sucht langfristig Gesundheit und kurzfristig Genuss und leidet durch diesen inneren Widerspruch ständig an sich selbst. Kognitive Dissonanzen pflegt man solche Widersprüche vornehm zu nennen.

Voting and Self-Image

December 4, 2013

People vote because voting is what they should do and they don’t want to lie if asked whether they did vote. This is found in a field experiment by Stefano DellaVigna et al. (paper, short interview).

Letting people know that others might ask them, is an obvious implication of our study, and it turns out that the Obama campaign did just that, too, as part of their turnout experiments. They let Democratic voters know that they would be asked whether they voted, and so this tight-knit community where there is some informal monitoring does seem to be one of the ways that keeps up voting. Now you may ask, “Is this a good or a bad thing, potentially inflicting shame and guilt on those that don’t vote?”, and that’s part of what we point to. That’s part of how we get voting to be high enough, which is generally a desirable objective.

Frank Hahn

February 22, 2013

Last month, Frank Hahn (1925-2013), one of the fathers of general equilibrium theory, has passed away.

In 1991 he wrote about the next 100 years of economic theory:

I am pretty certain that the following prediction will prove correct: theorising of the ‘pure’ sort will become both less enjoyable and less possible.

The full article, in which he argues that economics will become a ‘softer’ subject, is definitely worth reading.
Also, there is a tribute written by Geoff Harcourt (pdf).

Nobel Price goes to Roth & Shapley

October 16, 2012

As someone working in game theory I was delighted to hear that Alvin Roth and Lloyd Shapley were awared rthe 2012 Nobel Price in economics. Here is a nice piece on Roth’s work on dwarf-tossing and wife-carrying.
Veronika Grimm explains Shapley’s and Roth’s work on matching and its practical relevance for a broad audience here (in German).
