I have yet to see a scholarly article showing that productivity caused deflation (currency held constant while increases in population or productivity cause prices to drop) has caused economic problems. There is much evidence of currency removal caused deflation (when a large amount of currency or credit is quickly removed from the system causing prices to drop) wreaking havoc on the economy.

I am interested if you have seen any documented evidence of the former?

Also, in the US under the gold standard (1776-1910), we saw history's greatest increase in individual wealth ever recorded (measured by per capita GDP). Yes it was more volatile than under a fiat currency, but it's hard to argue that a constant or slow growing currency dampens economic growth with that data point.
