The aim of this paper is to carry out a sectorial causality analysis between prices and unit labour costs for the Spanish regions. In order to achieve our goal, we have developed our own database for the unit labour costs (ULC). It includes data for Spain and five of its regions: Andalusia,...

This paper studies the relation between inflation and relative price variability (RPV) in Spain during the 1987-2009 period. We find that this relation presents a U-shape profile, and that the optimal annual inflation rate (defined as the one that minimizes RPV) is around 4%, higher than the 2%...

In this paper we examine the case of partial central bank transparency and the interaction between public debt management and the design of monetary institutions.

According to the relevant literature, monetary policy implications concerning the optimal inflation rate can be derived by examining the relationship between inflation and the Relative Price Variability (RPV). This paper studies this issue for selected Euro Area (EA) countries, using monthly...
