investigating the existence of new non-ricardian regime policy in iran

the aim of this paper is to investigate the existence of the new non-ricardian regime policy in iranian economy. we detected signs of the non-ricardian regime from quarterly data of 1369 to 1391. to investigate further a dynamic stochastic general equilibrium model is designed to estimate the fiscal and monetary parameters using a bayesian approach. our results indicated a passive monetary policy and an active fiscal policy presence which are evidence of a new non-ricardian regime. to prove the robustness of our results, criteria such as posterior odds ratio and impulse response functions are used in this research. based on posterior odds ratio, non-ricardian policy has more ability to describe data than ricardian policy.  according to the impulse response function, in reaction to positive government debt shocks, non-ricardian policy implementation is more compatible with the behavior of the iranian economy than the other. jel classification: e12, e31, e42, e43
