> What makes an economy "Nitzchean"?
Given the German background of the author and the intended audience of art curators, I guess that this is an allusion to the work of Peter Behrens for AEG at the turn of the 20th century. Behrens' commission to provide a "total" design presence for AEG came from Emil Rathenau, who was deeply inspired by Nietzsche:

(Although you'd have to go here: <http://www.amazon.com/Industriekultur-Peter-Behrens-AEG-1907-1914/dp/0262021951/ref=sr_1_1?ie=UTF8&qid=1316872531&sr=8-1> to get any of the Nietzsche stuff.)
So in the context of Diederichsen's essay, perhaps it implies a transfer of a Nietzschean worldview from the "Fordist" to "Post-fordist" economy?
