Did you bother to read Jeff's article? He stated his definition of inflation and his classical leanings at the very beginning! He doesn't have to repeat it 55 times because someone refused to read.

Of course I did. He didn't acknowledge that there are two definitions of inflation and that he was using the less common, but maybe more rigorous, definition. His statement was also a bit ambiguous as to whether he was using the Austrian School definition of inflation or the Austrian School theory of interest rates. If *you* read his statement, you'll see that he referred to the Austrian School WRT interest rates, but didn't indicate that WRT his definition of inflation.

You have to realize that the Austrian definition of inflation is *not* the common accepted definition. Look up the Wikipedia definition of inflation and you'll see this. That *certainly* doesn't mean that the Austrian School definition is wrong, but when you're using an uncommon definition of a commonly understood word, you're better off acknowledging the discrepancy up front and making it clear you're using the less common version.

Whether he labeled it or not, he clearly stated his definition.

Inflation is the decrease in purchasing power of a currency due to an expansion in the supply of that currency ('printing money') and the interest rate offered by that currency's central bank.

How much clearer does he need to be? Is this like "depletion", which many around here confuse with "decline" but which is actually what happens from the time the first drop comes out of an oil well? Do we expect the readers of this site to be conversant with the word depletion and what it really means or the commonly accepted (and incorrect) version?
