We have already established what we (at least the most vociferous of us,

The Excel Depression
By PAUL KRUGMAN
Did a coding error basically destroy the economies of the Western world? 
You be the judge.

"...Finally, Ms. Reinhart and Mr. Rogoff allowed researchers at the 
University of Massachusetts to look at their original spreadsheet - and 
the mystery of the irreproducible results was solved. First, they 
omitted some data; second, they used unusual and highly questionable 
statistical procedures; and finally, yes, they made an Excel coding 
error. Correct these oddities and errors, and you get what other 
researchers have found..."
