The theory of optimal currency areas stresses that a single currency zone should have symmetry across shocks and structures. What happens if the monetary transmission mechanisms differ so that a common monetary policy has different effects in different places? Using a fully specified econometric...

This paper analyses the reliability of real time estimates of cyclically adjust budget balances (CABs). We find that real time CABs are not better at forecasting the ex post figures than simpler benchmarks. Further, we find that real time CABs have low power in detecting fiscal slippages, and in...

It is widely accepted that structural, institutional and labour market reforms are essential for the development of the OECD and emerging market economies; and that argument has been incorporated into official policy in the EU as part of the Lisbon agenda. Yet there is little analysis in the...

The identification of a possible European business cycle has been inconclusive and is complicated by the enlargement to the new member states and their transition to market economies. This paper shows how to decompose a business cycle into a time-frequency framework in a way that allows us to...

Most people accept that structural and labour market reforms are needed in Europe. However few have been undertaken. The usual conjecture is that reforms are costly in economic performance and costly to finance. Blanchard and Giavazzi (2003) and Spector (2004) develop a general equilibrium model...

This paper studies the incentives to enlarge a monetary union under alternative assumptions about the extent of market reform within the union and in candidate countries. Lack of labour mobility, or wage/price flexibility, or fiscal reform, brings costs for both new entrants and in the existing...

This paper investigates the uncovered interest parity hypothesis in an unusual way. We provide empirical evidence on the efficiency of capital markets using a time domain approach. However, a common prediction from theoretical models is that inefficient capital markets cause greater volatility...

The governments of four ex-Soviet countries recently discussed forming a currency union. To examine the economic feasibility of this proposition, we use conventional techniques and show that the arrangement is likely to find it difficult to handle the lack of structural symmetry, the asymmetric...
