Abstract
Rational expectations approach has some radical policy implications. It implies that systematic policies cannot influence real variables even in the short run, since people would have already anticipated what the policies are going to be and acted upon those anticipations. Thus, except for unpredictable random shocks, steady-state equilibrium always prevail and systematic monetary changes produce no suprises, no disappointed expectations, no transitory impacts on real economic activity. Ta have an impact on output and employment the authorities must be able to create a divergence between actual and expected inflation. Rational agents can use past observations on the behavior of the authorities to predict future policy moves. When stabilization actions do occur, they will have no impact on real variables since they will have been discounted and neutralized in advance. In this study, we analyse how was affected inflation in Turkey from both random shocks and unanticipated policy actions, within the framework of determined above.
