The data are held in separate files for the production and consumption series, with the files labelled lprodoo.txt and lconsoo.txt respectively. Both are ASCII files, with one line per observation. The source is the UK Office for National Statistics (ONS).Further details are: Lprod.oo contains 159 quarterly observations, covering the period 1955:01 to 1994:03. The variable is the (natural) logarithm of seasonally adjusted output of total production industries (ONS code DVZI). Lcons.oo contains 157 quarterly observations, covering the period 1955:01 to 1994:01. The variable is the (natural) logarithm of seasonally adjusted real aggregate consumers' expenditure (ONS code CAAB). These two files, which are in DOS format, are zipped in the file oodata.zip.
