Most, but not all, studies pertain to periods of a floating as distinct from fixed exchange rate.

The earliest date of any PPP testing in this survey is the U.S. colonial period, and all authors paid attention to the stationarity issue. Bordo and Marcotte (1937) found that PPP holds under the South Carolina adjustably fixed exchange rate and proportionality could not be rejected. Choudhry and Luintel (1934) examined Pennsylvania under a floating exchange rate, and PPP results are mixed. Bernholz (1985) examined the period of the 13 colonies in rebellion, during which Congress issued Continental currency. During this paper standard and floating exchange rate, the price of specie (silver coin—representing the exchange rate) did not increase as much as the price index.
