This possibility is establish on an extension and variation of the police of one(a) footing as applied to the aggregate economy . To explain the theory it is best , first , to review the idea behind the law of one priceThe Law of One Price (LoOPThe idea among the law of one price is that monovular goods selling in an integrated foodstuff , where there are no dose costs or differential taxes or subsidies , should sell at identical prices .
