The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

The new Keynesian monetary policy model studies the response of the inflation – output gap trade-off to policy decisions taken by the Central Bank, concerning the nominal interest rate time trajectory. Under an optimal setup, this model displays a saddle-path stable equilibrium and, if the...

We make a case for the usefulness of an optimal control approach for the central banks’ choice of interest rates in inflation target regimes. We illustrate with data from selected developed and emerging countries with longest experience of inflation targeting.

This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...

The main purpose of this paper is to show evidence about the negative impact of oil price shocks in the economy of Spain. Since oil demand is continuously increasing all around the world and OPEC countries use to act having certain power to raise them, it is necessary to study how these price...
