We examine the expectational stability (E—stability) of rational expectations equilibrium in the standard, “New Keynesian” model of the monetary transmission mechanism when monetary policy is optimally derived. We suppose that the monetary authority adds interest rate stabilization to its other two objectives of inflation and output stabilization, and we consider the optimal interest rate rule ...

This paper investigates the dynamic effects of monetary and fiscal policy in a monetary union, which is characterized by asymmetric interest rate transmission. This asymmetry gives rise to intertemporal reversals in the relative effectiveness of policy on member country outputs. The direction and the number of these reversals depend on whether policies are unanticipated or anticipated. We also ...

It is believed that a common monetary policy in a monetary union will have identical effects on different countries as long as these countries have identical fundamentals. We show that, when there is specialization in production, the terms of trade react to the shock. The transmission mechanism of a monetary shock has in this case an additional channel, the terms of trade. This is the case even...

a r t i c l e i n f o This paper introduces a strategy to model a small open economy, whose central bank has established two simultaneous policy objectives: an inflation target, and a maximum limit for nominal exchange rate volatility. In line with the Tinbergen–Aoki condition, the monetary authority establishes two policy instruments, one for accomplishing each target: the monetary policy rate...

During the last decade, Latin American economies have transformed their monetary policy arrangements. Most countries in the region have given their monetary authorities more independence and/or developed policy frameworks that put greater emphasis on controlling inflation. Furthermore, monetary operations have shifted towards market-based frameworks. These arrangements should in principle be be...

This paper studies the implications of certain kinds of uncertainty for monetary policy. It first describes the optimum policy rule in a simple model of the transmission mechanism as in Ball and Svensson. It then examines how this rule ought to be modified when there is uncertainty about the parameters, about the time lags, or about the nature of shocks. The paper also discusses the case of a s...
