What is Geo-Rent?

Geo-Rent: A Plea to Public Economists -- EconJournal Watch, April 2005, by Dr. Fred Foldvary, Santa Clara University Dept. of Economics, 2000 LPCA candidate for Congress in CA09

Note that Dr. Foldvary was for years predicting that a real-estate-based economic crash would occur around 2008.  For example, in 2004: http://www.progress.org/2004/fold334.htm.  In early 2007 he even published a booklet titled The Depression of 2008.
