in this paper we have utilized optimum control procedures to derive an optimum monetary rule for iran’s economy ; assuming the policy makers are using the interest rate as a policy variable. in doing so a dynamic stochastic model with rational expectation was setup. the model is calibrated with the use of previous findings in the literature. the results show that the optimum reacrion of the pol...

t he relationship between the price of oil and the level of economic activity is a fundamental empirical issue in macroeconomics. in this research, by using a multivariate garch-in-mean var, we try to investigate direct effects of uncertainty of oil price on macroeconomics of iran by using annually data from 1965 to 2013.results show that uncertainty about oil prices had a negative and signific...

The names Milton Friedman and John Taylor are associated with different monetary policy rules; but, as shown in this paper, the difference between their perceptions of how the economy works is not great. The monetary policy rules advanced by Taylor and Friedman are compared by linking the rules to the two economists’ underlying views about nominal rigidity, the source of trade-offs, the sources...

This paper reformulates the issue of the international coordination of monetary policy in the framework of an extended game with observable delay, where governments are required to set the timing of their respective actions before proceeding to the actual choice of their monetary policies. This allows to shrink signi...cantly the set of equilibria. JEL Classi...cation: D43, E61, F41, F42

This paper considers political credibility of allocations in settings with dynamic private information. It embeds a benchmark dynamic moral environment into political economy games which feature repeated voting over mechanisms. Optimal politically credible allocations are shown to solve virtual planning problems with social discount factors in excess of the private one. JEL codes: C73, D72, D82...

Today, small and medium-sized enterprises (SMEs) play a key role in both developing and developed economies. However, the uncertainty of macroeconomic indicators, such as economic growth, may affect financing and investment of the SMEs in an economy. The present study explores the effect of the economic growth rate uncertainty on financing SMEs in Iran. To this end, the study has applied the Br...

To evaluate the Greenspan era, we nevertheless need to address three questions: Is his success due to talent or just luck? Does he have a system of monetary policy or is he himself the system? What will be his legacy? Greenspan was certainly lucky, but he was also clairvoyant. Above all, he has developed a profoundly original monetary policy. His confidence strategy is clearly opposed to the cr...

Several recent papers have proposed recursive Lagrangian-basedmethods for solving dynamic contracting problems. Thesemethods give rise to Bellman operators that incorporate either a dual inf-sup or a saddle point operation. We give conditions that ensure the Bellman operator implied by a dual recursive formulation is contractive. JEL codes: C61, C73, D82, E61.
