This paper uses a dynamic factor model for the quarterly changes in consumption goods’ prices to separate them into three components: idiosyncratic relative-price changes, aggregate relative-price changes, and changes in the unit of account. The model identifies a measure of “pure”...

We propose and implement a method that provides quantitative estimates of the extent to which higher-than-expected inflation can lower the real value of outstanding government debt. Looking forward, we derive a formula for the debt burden that relies on detailed information about debt maturity...

This article summarizes our views on the role of an 'aggregation bias' in explaining the PPP Puzzle, in response to the several papers recently written in reaction to our initial contribution. We discuss in particular the criticisms of Imbs, Mumtaz, Ravn and Rey (2002) presented in Chen and...

We study the extent of macroeconomic convergence/divergence among euro area countries. Our analysis focuses on four variables (unemployment, inflation, relative prices and the current account), and seeks to uncover the role played by monetary union as a convergence factor by using non-euro...

Standard growth accounting exercises find large cross-country differences in aggregate TFP. Here we ask whether specific sectors are driving these differences, and, if this is the case, which these problem sectors are. We argue that to answer these questions we need to consider four sectors. In...

Structural vector autoregressions are used to analyse the relationship between real output and relative prices within the European Union (EU) and the United States. Relative price variability appears to be more important for adjustment within the EU than the United States, reflecting the lower...

This proposal involves the establishment of ‘welfare accounts’ for every person in a country. There are four accounts: a retirement account (covering pensions), an unemployment account (covering unemployment support), a human capital account (covering education and training), and a health...

This paper considers the Great Inflation of the 1970s in Japan and Germany. From 1975 onward these countries had low inflation relative to other large economies. Traditionally, this success is attributed to stronger discipline on the part of Japan and Germany’s monetary authorities - for...

We develop a simple model to study how relative wage rigidity affects equilibrium taxation. It is argued that relative wage rigidity, by compressing incomes within the middle class, leads to a lower degree of redistributive conflict within the politically important core of society, even though...

The prevailing labour market models assume that minimum wages do not affect the labour supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum...
