The data used in the paper are from the first six waves (1991-1996) of
the British Household Panel Survey (BHPS). Researchers may apply for
access to BHPS data from the UK Data Archive and will be required to

The sample used in the paper was restricted to individuals who were
Original Sample Members, were aged between 18 and the state retirement
age (65 for men and 60 for women), were not full-time students, and were
in the labour force (employed or unemployed) at the time of interview.
The unemployment indicator used is constructed on the basis of the
ILO/OECD definition of unemployment.  Under this definition a person is
unemployed if he or she does not have a job, but had looked for work in
the past four weeks and is available for work. (BHPS variables used:
fjbhas, fjboff, fjbsemp, fjulk1, fjulk4 - see below.) The wage variable
is adjusted to April 1997 using the Average Earnings Index.

The following BHPS variables were used. In the public release files,
variable names are prefixed by a letter indicating the survey wave, e.g.
'a' for wave 1, 'b' for wave 2, etc. Variables listed below with prefix
'f' (and pid) were extracted for all 6 waves used (i.e. 'a'-'f').
