UK National Accounts: GDP and Input-Output Supply and Use Tables
Paper prepared for the 16th International Input-Output Conference in Turkey (July 2007)
Productivity measures are constructed from output and input data. This paper focuses on output measures produced within the UK National Accounts. The basic framework of the UK National Accounts is provided alongside an explanation of how they are constructed.
A detailed description of gross domestic product (GDP) is given and compared with gross value added (GVA). As part of this, the three approaches to measuring GDP are explained and compared.
This paper also outlines the Input-Output Supply and Use Tables as they are produced in the UK and how they are used as a framework to reconcile the three different approaches to measuring GDP. In turn, these tables are used to underpin the single estimate of current price GDP as derived from the production, income and expenditure approaches.
The Input-Output Supply and Use Tables provide the natural framework which links the inputs used, GVA and the outputs produced on a consistent basis. The industrial analyses produced through these tables provide the natural links to the work on productivity for a range of users.
To produce good quality estimates of productivity, consistent and coherent estimates of outputs produced with the inputs used are required. The data on outputs used in the productivity work are derived from various parts of the UK National Accounts. This paper also forms an input to The ONS Productivity Handbook - A Statistical Overview and Guide (ONS 2007).
