Based on country-by-country analysis, we conclude that monetary models do not provide the expected results. We reveal several shortcomings of the models and examine the building blocks of the fundamental version. Although researchers always blame the deviations from purchasing power parity as the reason for the failure of the monetary model, our analysis indicates that invalidity of Keynesian money demand function is also responsible for unfavourable results.spatechnical reporthttp://www.aeefi.comopen accessF31F41Exchange rateFlexible price monetary modelForward-looking monetary modelReal interest differential modelMoney demandPurchasing power parityEconometría (Economía)Economía internacionalFinanzas5302 Econometría5310 Economía Internacional
