What causes market bubbles, and are we in one?

An all-star group of media economics experts gathered at the University of Navarra Dec. 13 and 14 to exchange ideas and research results on the role and behavior of media during periods of economic or financial boom and crash.

Many of the presentations centered on media coverage of the global financial crisis of 2008-2009 and its impact in countries including Ireland, England, Greece, Spain, the U.S., the Netherlands, Germany, and Denmark. The papers provoked lively debate among the participants, since there was significant time between presentations for questions and comments.

The studies used ingenious research methods and rigorous statistical analysis to tease out surprising insights. I had the unenviable task of providing a summary at the end, on a Friday night, in just 10 minutes. So here is the cheeky result, with apologies to my learned colleagues:

� Uninterested in economics
� Ignorant
� . . . even willfully ignorant
� Lazy, complacent
� Delusional

� Uninterested, ignorant
� Lazy, complacent
� Unethical
� Sometimes corrupt
