( planner or an agent) change over time. Kydlnd and Prescott) 2004( , declares that the reason of stagflation in the 1970s is due to time inconsistency caused by discretionary government intervention
In this paper, we introduce the phenomenon of time inconsistency, focusing on fiscal policy . To test this phenomenon, the long-run Phillips curve و time series data for the years 1979 to 2009 and the method of ordinary least squares (OLS) , Augmented Dicky Fuler test of Unit root , vectors based on regression (VAR) have been used, locus Crises , recursive and rolling regression is applied. The results show that, Iranian economy is suffering from the phenomenon of time inconsistency, because of government’s fiscal intervention.
