بررسی اثرات غیر خطی سیاست مالی بر مصرف خصوصی ایران در یک الگوی چرخش مارکوف با احتمال انتقال متغیر با زمان

If with expansionary (contractionary) fiscal policy, private consumption increases (decreases), fiscal policy has Keynesian nature else, it has non- Keynesian nature. If in certain period, sometimes fiscal policy has Keynesian effects and sometimes it has non- Keynesian effects, it will have non-linear effects. Since, there is not a paper about non- linear fiscal policy in IRAN, the purpose of this paper, is to test the non-linear effects of fiscal policy on private consumption in IRAN, during 1993:2-2010:4. So we use a Markov-switching model with FTP and TVTP approach. The results of the estimation of the Markov switching model with FTP present the existence of significant non-linarites in the effects of fiscal policy in IRAN. Also the Keynesian regime is an absorbing regime such that the probability of remaining in the non- Keynesian regime is just, 1%. Furthermore, Estimation results for the TVTP model show that we cannot find any strong evidence about the sources of these non-linarites.
