New Eurocoin: Methodology for real-time economic tracking
The Banca d'Italia provides a tutorial explaining the methodology behind its New Eurocoin indicator. This tool tracks euro area economic growth in real time by combining comprehensive data with advanced filtering techniques.
Beyond GDP: A timely, comprehensive view
The Eurocoin indicator addresses limitations of traditional measures like GDP, Industrial Production (IP), and surveys.
While GDP is comprehensive, it's only released quarterly and with delay.
IP and surveys are timelier but lack comprehensiveness or contain subjective judgments.
Eurocoin combines the best aspects: it is comprehensive, covering production, services, and the public sector like GDP.
Crucially, it is released monthly, providing a reliable, daily estimate of the economy's state.
Furthermore, Eurocoin is specifically designed to be free from short-run fluctuations, offering a clearer picture of underlying economic trends for economists and policymakers.
Filtering out short-run noise
Analyzing business cycles requires distinguishing medium- to long-run trends from short-run oscillations.
Simple year-on-year growth rates, while smoothing data, introduce phase distortion, delaying observed peaks and troughs.
The Eurocoin methodology utilizes advanced band-pass filters, which are centered and symmetric moving averages.
This technique effectively removes oscillations shorter than one year while preserving the phase of the underlying medium-long-run component.
A key challenge is the 'end-of-sample problem,' where unobserved future data points must be forecasted, potentially leading to revisions and misleading real-time assessments.
Real-time clarity, not just data
Eurocoin's core innovation lies in its ability to provide a reliable, real-time estimate of the underlying economic cycle, overcoming the end-of-sample issues inherent in traditional filtering.
This allows policymakers and economists to make more informed assessments without being misled by temporary fluctuations or delayed data.
Its sophisticated approach offers a clearer, more immediate picture of the euro area's economic health.
