A Note on Band-Pass Filters Based on the Hodrick-Prescott Filter and the OECD System of Composite Leading Indicators

The Organisation for Economic Co-operation and Development (OECD) began to use a band-pass filter, based on the Hodrick-Prescott filter (HPband-pass filter), to calculate the composite leading indicators (CLIs) in December2008. Other than the filter adopted by the OECD, there is an alternative HPband-pass filter. This note examines whether the application of these two alternative HPband-pass filters in the calculations of the OECD’s CLIs lead to negligible differences.
