The data used in this paper are the property of Institute for Social and Economic Research (University of Essex) who do not permit open access. Therefore, the data cannot be lodged here. They are held at the ESRC (UK) Data Archive (http:dawww.essex.ac.uk), to whom enquiries concerning access should be addressed. Information concerning the Archive holding can be obtained using the "BIRON" search engine (http:biron.essex.ac.uk). The study title under which the data are held is "British Household Panel Survey". Every year a new wave of data is added to the study. At the time of writing, waves 1-5 were available. Records were constructed for each Head of Household in the first wave, AHOH = 1 in file AINDALL. The age of the individual was recorded in variable AAGE12 in the AINDALL response file. The income of the individual in any year was constructed as the sum of the variables *FIYRL, *FIYRP and *FIYRB in the respective *INDRESP files, one for each wave (* = A to E). The income in each year was adjusted to 1990 prices using the Implied Consumption Deflator which has the following values 1990 1991 1992 1993 1994 1995 108.585 113.188 117.529 120.253 123.356 126.755 The individual was assumed to have a tertiary education if the variable *QFEDHI for that individual had a value below 7 in any of the fives waves of the *INDRESP files. We excluded from the estimation any records where the income history was incomplete, the age of the head household was not between the ages of 20 and 54 or the income of the head in any year was below £900 or above £200,000. In the paper, we also record results for dynamics of household income. The equivalent household income is the household income divided by its McClements equivalent size. Household income was the sum of the variables *FIHHYL, *FIHHYB and *FIHHYP in the respective *HHRESP files. Its equivalent size in any year was constructed from the variables *HGR2R, *AGE and *DEPCHL from the respective *INDALL files. Again we excluded from the estimation any records where the income history was incomplete, the age of the head household was not between the ages of 20 and 54 or the equivalent income of the household in any year was below £900 or above £200,000.
