It is the 100th anniversary of Irving Fisher’s 1911 book The Purchasing Power of Money . But, more important than that, it is a good time, during the current ﬁnancial turmoil, to reconsider some of his theories again, in light of current events. And I think that some of his theories about variations in the purchasing power of money are very important today, have been underappreciated, and are worthy of considering anew.
