This paper studies the synchronization of output fluctuations in European regions and US counties. We extend the two component dynamic factor model à la Sargent and Sims (1977) by introducing an intermediate-level shock, which is common to all regions (counties) in each country (state), but it...

This paper presents ideas and methods underlying the construction of an indicator that tracks euro area GDP growth but, unlike GDP growth, (i) is updated monthly and almost in real time, and (ii) is free from short-run dynamics. Removal of short-run dynamics from a time series to isolate the...

This paper develops a method to analyse large cross-sections with non-trivial time dimensions. The method: (i) identifies the number of common shocks in a factor analytic model; (ii) estimates the unobserved common dynamic component; (iii) shows how to test for fundamentality of the common...

This Paper is the result of the Bank of Italy-CEPR project to construct a monthly coincident indicator of the business cycle of the euro area. The index is estimated on the basis of a harmonized data set of monthly statistics of the euro area (951 series) which we constructed from a variety of...

The literature on localised knowledge spillovers and growth focuses on the relative importance of intra vs. inter-industry externalities, but the nature and the characteristics of the dynamic linkages across manufacturing sectors are not investigated. In this Paper we perform a very...

This paper analyses output and productivity for 450 US industries from 1958 to 1986. We make the following contributions. (i) We develop a method based on dynamic principal components to identify the number of common shocks to our data set. (ii) We propose a simple method for the estimation of...
