Recently, time-varying uncertainty has attracted a lot of attention from policymakers and academics and has led to the growth of literature identifying the transmission mechanisms of uncertainty shocks. Precautionary pricing incentive is an important mechanism that amplifies uncertainty shocks. The conclusion from the comparison of allocations under optimal monetary policies is modeled in two common pricing approaches, Calvo and Rotemberg.
The main goal of this research is to investigate the optimal monetary policy with uncertainty in Iran's economy under different pricing conditions by modeling two common pricing approaches, Calvo and Rotemberg, which is based on a dynamic stochastic general equilibrium model based on the new Keynesian perspective using The available information and statistics of Iran's economy from 2001 to 2021, have been designed according to the realities of Iran's economy.
The results showed that the uncertainty shocks under Calvo and Rotemberg's pricing assumptions when the monetary policy is adjusted based on Taylor's empirical law are spread differently in the Iranian economy. In such a way that they behave like cost pressure shocks under Calvo pricing and negative demand shocks under Rotemberg pricing. However, the optimal monetary policy leads to the stabilization of both inflation and output gap under both pricing assumptions. In other words, adopting optimal monetary policies can lead to economic stability. Because optimal monetary policy removes not only the discretionary savings incentive of households but also the discretionary pricing incentive of firms, the key channel differentiates Calvo's pricing prediction from Rothenberg's pricing prediction under empirical Taylor. According to the results of the present research, it is suggested to use the monetary rule for policy-making to create a nominal anchor for economic actors and not to use discretionary policies in order not to create inflationary expectations in the economy.
