Another specification that has received considerable attention is that policymakers may have asymmetric preferences with regard to their objectives during recessions and expansions. Since according to Law for Usury (Interest) Free Banking of Iran, the objective of the central bank is not the control of interest rate, instead it is money growth rate which is used as an instrument, in this study we introduce a money growth rate reaction function and we use it to test the asymmetry in central bank behavior during recessions and expansions. The estimation results of a Markov Switching model for the period 1367:1 to 1387:2 show that the central bank sensitivity toward output is more during the recessions while its sensitivity toward inflation is more during the expansions.
