This paper presents a model in which "instrument uncertainty"—that is, an uncertain mapping from monetary policy to macroeconomic outcomes—may mitigate the inflationary bias problem that arises when efficient monetary policy rules are time-inconsistent. If the relation between monetary policy and macroeconomic outcomes is uncertain, the private sector has an incentive to scrutinize the past for...

A currency area can be a self-validating optimal policy regime, even when monetary unification does not foster real economic integration and intra-industry trade. In our model firms choose the degree of exchange rate pass-through onto export prices accounting for expected monetary policies, and monetary authorities choose optimal policy rules taking firms’ pass-through as given. We show that th...

Since the 1990s there have been a number of major changes in the design and conduct of monetary policy. In a globalized environment, there is less time to adjust to shocks and greater need to achieve closer convergence of economic performance among trading partners. As a result, a number of developing countries have adopted exchange rate regimes with more flexibility, and thereby greater scope ...

This study investigates monetary and financial shocks on macroeconomic variables, focusing on the role of banking intervention. For this purpose, a Keynesian dynamic stochastic general equilibrium (DSGE) model is designed for Iran’s economy that involves financial and banking sectors. The results of the model simulation show that the financial accelerator theory works in the Iranian economy. Al...

the ultimate goal of monetary policy is to achieve price stability and high output. in this regard, central banks usually change the interest rate, liquidity, and money base in order to apply monetary policies. the john b. taylor rule is one of the rules known in the transmission of monetary policy.[1] based on this rule and given the output gap and inflation gap, the central bank increases or ...

This paper asks whether an aggressive monetary policy response to inflation is feasible in countries that suffer from fiscal dominance, as long as monetary policy also responds to fiscal variables. We find that if nominal interest rates are allowed to respond to government debt, even aggressive rules that satisfy the Taylor principle can produce unique equilibria. But following such rules resul...

We study the interaction of multiple large economies in dynamic stochastic general equilibrium. Each economy has a monetary policymaker that attempts to control the economy through the use of a linear nominal interest rate feedback rule. We show how the determinacy of worldwide equilibrium depends on the joint behavior of policymakers worldwide. We also show how indeterminacy exposes all econom...

This paper focuses on simple normative rules for monetary policy that central banks can use to guide their interest rate decisions. Such rules were first derived from research on empirical monetary models with rational expectations and sticky prices built in the 1970s and 1980s. During the past two decades substantial progress has been made in establishing that such rules are robust. They perfo...

Several papers have documented a regime switch in US monetary policy from ‘passive’ and destabilizing in the pre-1979 period to ‘active’ and stabilizing afterwards. These studies typically work with DSGE models with rational expectations. This paper relaxes the assumption of rational expectations and allows for learning instead. Economic agents form expectations from simple models and update th...
