<s>[INST] The next text is a question of a member of the European parliament:"In its reply to Written Question E-0273/00(1) the Commission appears to be confusing two different phenomena: the existence of price differences resulting from administrative and/or macroeconomic policy measures, generally considered on the basis of the classic text """"""""The Purchasing Power of Money"""""""" by Irving Fisher, and differences in market value for equal or similar goods and services arising from differences in supply and/or demand best summed up by JohnMaynard Keynes.  Keynes quotes Dr Watson on a visit to the Isle of Skye, when he says (and I quote from memory) that, if the eggs on your miserable island are cheap, it is not because there is an abundance of eggs but because money is scarce.  The problem posed here is impossible to resolve in the context of statistical method, because it belongs to the field of economic theory.  As conceived by Fisher, PPPs represent the appropriate method for looking beyond price differences which do not stem from market mechanisms, which is not the case when the market itself attaches different values to goods.  As Dr Watson realised using his own common sense, the value of goods and services varies not only according to conditions of supply but also according to conditions of demand, especially where their mobility is low.  That being so, does the Commission not consider it absurd to correct the overall income of a particular geographical area using the assumed market value of goods and services in that area, to the extent that possible differences in prices do not reflect administrative measures?  Does the Commission not believe that it would be appropriate to use an in-depth knowledge of economic theory as a basis before proposing measures to correct income in real terms, such as PPPs?    (1)OJ C 330 E, 21.11.2000, p. 114."
