Labour Productivity Measures from the ABS: 1998 to 2009 Author Name(s): Jean Acheson, ONS
Abstract This article compares micro and macro measures of productivity. Detailed industry-level productivity estimates are key to understanding how the aggregate economy is driven by the performance of particular sectors, and also how certain sectors perform relative to others. A detailed focus is all the more important in the aftermath of the UK’s deepest recession since the 1930s. This article aims to aid the analysis of the economy over the recession and comment on which specific industries saw the biggest changes. The article updates the work of Long (2010) by adding two additional years of data from the Annual Business Survey (ABS), 2008 and 2009.

Introduction The Annual Business Survey (ABS), formerly known as the Annual Business Inquiry (ABI), is an annually conducted business survey which covers the market sector of the economy but excludes 1
part of agriculture, forestry and fishing and most of financial services. It brings together employment and financial data into one dataset where previously this was collected using various different 2
surveys. This allows the aggregates to be produced using a common methodology, resulting in greater consistency between input and output data. Coherent estimates of nominal value-added per job can consequently be produced at a detailed level. 3
The ABS estimates cover UK businesses registered for VAT and/or PAYE, classified to SIC 2007. There are two sources for the ABS: one is the Business Register Employment Survey (BRES) 4
which provides the employment data and ABI/2, which provides the financial data. Both surveys use different samples taken from the Interdepartmental Business Register (IDBR), but are merged together at the four or five-digit SIC level.

The significant change in industrial classification over the ABS time series – SIC 2007 was introduced in the 2008 publication – meant that a choice had to be made over how to characterise the industrial breakdown of the data for this article. It was not possible to accurately convert the back series, 1998 to 2007, to SIC 2007 as not all firms sampled over this time period have remained on the IDBR and thus have a SIC 2007 converter variable associated with them. As both the 2008 and 2009 employment data from BRES were readily available on both SIC 2003 and SIC 2007, it was felt that, for the sake of accuracy, converting two years of financial data from ABI/2 to SIC 2003 would achieve more accurate results than converting ten years of both datasets to SIC 2007. As such, any reference to National Accounts industry-level data in this article is consistent with Blue Book 2010, rather than Blue Book 2011, as 2010 was the last Blue Book to be published on a SIC 2003 basis.
