 In December 2012 Schiff wrote an article entitled "Mish Shedlock exposed" in which he criticized Shedlock for selective use of short-term data in the financial crisis and argued that his investment strategy had made strong returns over the long-run.Schiff's views have been criticized several times by economist Paul Krugman, who defines inflation very differently from Schiff, focusing on CPI increases, rather than monetary and asset price inflation, which Schiff believes eventually lead to increases in consumer prices after an indefinite waiting period.In October 2010, Krugman wrote, "I keep being told that Peter Schiff has been right about everything; so, how's that hyperinflation thing going?"
