This paper studies the welfare impact of a common monetary policy in the context of a two-country, general equilibrium model with liquidity effect and nominal wage contracts, heterogeneous agents, imperfect competition in the labor market, trade in goods, immobility of labor and mobility of...

Non-coordinated monetary policy is analysed in a stochastic two-country general equilibrium model. Non-coordinated equilibria are compared in two cases: one where policy is set in terms of state-contingent money supply rules and one where policy is set in terms of state-contingent nominal...

This paper uses a New-Keynesian model with multiple monetary assets to show that if the choice of instrument is based solely on its propensity to predict macroeconomic targets, a central bank may choose an inferior policy instrument. We compare a standard interest rate rule to a k-percent rule...

This paper studies optimal monetary policy with the nominal interest rate as the single policy instrument in an economy,where firms set prices in a staggered way without indexation and real money balances contribute separately to households'utility. The optimal deterministic steady state under...

The optimal choice of a monetary policy instrument depends on how tight and transparent the available instruments are and on whether policymakers can commit to future policies. Tightness is always desirable; transparency is only if policymakers cannot commit. Interest rates, which can be made...
