In this paper, we provide empirical evidence for the Spanish economy, over the period 1977-97, on whether monetary policy shocks have had different effects on real output growth depending on the state of the business cycle. To do so, we adopt an extension of Hamilton's (1989) Markov Switching...

This Paper derives optimal monetary policy rules in setups where certainty equivalence does not hold because either central bank preferences are not quadratic, and/or the aggregate supply relation is non-linear. Analytical results show that these features lead to sign and size asymmetries, and...

In this paper we show that the delegation of monetary policy to an independent and more conservative central banker is an optimal policy in an international context with monetary spillovers between countries, even in the absence of time inconsistency (credibility) issues. We also study the...
