U.S. Labor Dep't cites big strides on delayed PPI Fri Mar 12, 2004 03:44 PM ET "The wholesale price data had originally been scheduled for release on Feb. 19, over three weeks ago, but was postponed indefinitely when BLS ran into trouble converting the data to a new industrial classification system. BLS was also forced to postpone the report for February, which was to have been released earlier on Friday. Irwin Gerduk, an assistant commissioner at BLS, has said outdated computers were partly to blame for the delay. He told Reuters earlier this week it would take "quite a bit of time" to produce the February report even after the calculation problems for January were solved." http://www.reuters.com/financeNewsArticle.jhtml?type=economicNews&storyID=4558945 http://research.stlouisfed.org/fred2/categories/31 Last time we had a reclassification - reformulation revision, it was published February 9th 2001 and it was effective for the Jan 2001 numbers. It was done in a timely manner. A brief examination of changes due to the revision (2001) In the following a brief examination of the main areas in the revision is done. The areas are: Classification Weights Method of calculation Questions http://www.ssb.no/ppi_en/revision.html Does anyone know what changes/recalculations are taking effect this time? And why does it take so long? I find Irwin's response "Irwin Gerduk, an assistant commissioner at BLS, has said outdated computers were partly to blame for the delay" somewhat strange. (outdated computers?) I keep hearing opinions from traders and news outlets on the issue of delayed PPI numbers, as higher than expected inflation, data massaging, but it's just talk/rumors.
