I believe what he&#x27;s saying is that 1.02 1985-dollars (PPP adjusted) is greater than 1.08 1993-dollars (PPP adjusted).<p>Clicking the first two inflation calculators I found on Google and assuming their numbers are right (they both gave the same result), it does seem that if they had inflation adjusted the number using US rates, the original USD 1.02 should have been USD 1.37 by 1993.<p>EDIT: It&#x27;s of course important to keep in mind that inflation rates are different across the world, and presumably the world bank at least will insist that they accounted for real term price changes for the relevant goods, so I still don&#x27;t know how relevant this point in the article actually is.
