FOUNDATION FOR THE STUDY OF CYCLES, INC.
The World Center for Cycles Research

Their predictions made in 2009.

Established in 1941 by a Harvard economist who had identified a number of cycles in the U.S. economy.

The foundation endeavours to:

• Discover the causes and conditions for already observed and cataloged cyclic and rhythmic behaviors.
• Classify discovered causes and conditions with the physical sciences.
• Incorporate these causes and conditions into the mainstream of modern scientific theory and knowledge.

PS They have a “free e-books” section which unfortunately is missing.
PSS Hmm, pretty much everything is broken at that website (except for this), looks like it hasn’t been updated in awhile.
