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...

abstract today, debt stabilization in an uncertain environment is an important issue. in particular, the question how fiscal and monetary authorities should deal with this uncertainty is of much importance. especially for some developing countries such as iran, in which on average 60 percent of government revenues comes from oil, and consequently uncertainty about oil prices has a large effect ...

the main purpose of this paper is theoretically to design the optimal intervention in the foreign exchange market in iran, which has not been investigated by previous studies. the economic fundamentals are strongly affected by the optimal foreign exchange intervention, the consistency of foreign exchange intervention with other policies and political authorities' beliefs about the interven...

Recent work on optimal policy in sticky price models suggests that demand management through fiscal policy adds little to optimal monetary policy. We explore this consensus assignment in an economy subject to ‘deep’ habits at the level of individual goods where the counter-cyclicality of mark-ups this implies can result in government spending crowding-in private consumption in the short run. We...

We present a model in which a policymaker observes trade in a financial asset before deciding whether to intervene in the economy, for example by offering a bailout or monetary stimulus. Because an intervention erodes the value of private information, informed investors are reluctant to take short positions and selloffs are, therefore, less likely and less informative. The policymaker faces a t...

Next to the monoclinic polymorph [Cheng et al. (2005 ▶). Acta Cryst. E61, m892-m894], the triclinic title compound, [Fe(4)(C(2)H(5)S)(2)(S(2))(CO)(12)], is the second known form of this composition. The structure is composed of an [Fe(2)(C(2)H(5)S)(S)(CO)(6)] subcluster, which is linked to its counterpart by an inversion centre located at the mid-point of the central disulfide bond. The Fe(2)S(...

This paper provides a set of empirical tests of the cross-sectional variation of stock volatility and investablility, where investability is defined as the degree to which a stock is accessible to foreigners. Unlike previous studies, which focus on market volatility and market return, we study the relationship between individual stock return volatility and its investablility. Our findings have ...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon under rational expectations These requirements lead to instrument rules for interest rate setting that can be called CIP (constant interest rate projections) rules. We consider the twin questions of ...
