Lecturing Birds on Flying
Can Mathematical Theories Destroy the Financial Markets?
1. Auflage Mai 2009
400 Seiten, Hardcover
Fachbuch
Führende Finanzexperten diskutieren, auch konvers, seit Jahren über den Konflikt zwischen Theorie und Praxis. Als einer der ersten befasste sich Nassim Taleb in seinem, eher für Finanzexperten geschriebenen Buch "Dynamic Hedging" mit diesem Problem. Pablo Triana bereitet in "Lecturing Birds on Flying" das Thema nun für Laien verständlich auf und erläutert, warum Finanztheorien in der Praxis oftmals jegliche Relevanz verlieren. Dabei geht er nicht auf finanztechnische Details ein, sondern zeigt, dass allgemein anerkannte und täglich angewandte Theorien für unsere Wirtschaftswelt schädlich sein können. Sehr oft führen quantitative Modelle, mit denen Hedge Fonds und Investmentbanken (aber auch Regulierungsbehörden und Rating-Agenturen) arbeiten zu einem Zusammenbruch des Marktes. Diese sogenannten Modelle führen zu falschen Entscheidungen, wiegen Investoren in falscher Sicherheit und sanktionieren eher fragwürdige Verhaltensweisen. So waren diese Modelle maßgeblich für den Börsencrash des Jahres 1987, die LTCM-Pleite 1998, die Kreditkrise 2008 und viele andere größere oder kleinere Crashs verantwortlich. Seit Jahren schreibt Pablo Triana über die Grenzen dieser Art mathematischer Berechnungen und zeigt nun, welche Konsequenzen dieser Ansatz für unsere Märkte hat und warum das blinde Vertrauen auf quantitative Maximen eine große Gefahr in sich birgt.

"Readers of this book may make quite a lot of noise. . . Some will cheer out loud; others will yelp as cherished beliefs are torn into. At times, the book is deliberately incendiary. Triana is trying to stimulate debate. . . On the whole, this is a good read."
--The Financial Times, July 23rd 2009
"...calls for a return to "good old fashioned commonsense decision making"."
--Daily Express, June 4th 2009
"This book explains how it is that theoretical finance can fail dramatically in the real world."
--Finanace & Management Faculty, June 2009
"The book is fizzing with ideas"
--The Economist, June 29th 2009
" Triana's book will ruffle a lot of feathers, but it also will make many readers think hard."
--BizEd
"A deeply unsettling insider account of how bogus mathematics overtook finance and was a key contributor to the financial collapse of 2008-2009 . . . With deep insight, Triana deconstructs the "pillars" of mathematical finance . . . Like Nassim Taleb, celebrated author of The Black Swan (2007), Triana is calling for major surgical reform of such business schools' curricula. An important addition to our deeper understanding of how finance must be reformed."
--Hazel Henderson, Ethical Markets
"Should the Nobel Prize for economics be abolished? That is one of the suggestions in Pablo Triana's provocative book "Lecturing Birds on Flying: Can Mathematical Theories Destroy the Markets?" . . . As Nassim Nicholas Taleb writes in his witty introduction to the book, giving someone the wrong map is worse than giving them no map at all. . . a good read. Some may find the elaborate prose closer to Cervantes than to, say, Nobel Prize winner Robert Merton -- annoying. But perhaps Cervantes is the right writer to emulate when tilting at windmills. "
--LA Times
"The highlight of Triana's book is his valuable insights into the problems with mathematical economic models, which make his argument quite forceful."
