This paper examines the 'learning economy' from the perspective of occupati
onal characteristics and changes in the British labour market between 1980
and 1992. Following a discussion of the learning and knowledge economy, cro
ss-sectional employment data are analysed to ascertain which occupations ca
n be classified as knowledge-based. Longitudinal career history data are th
en used to trace the flows of these 'knowledge workers' over time. Sectoral
shifts are examined, with a particular focus on the knowledge-intensive se
rvice sectors. The data come from the Employment in Britain survey: a large
-scale employee survey from 1992. The approach used allows us to measure so
mewhat intangible aspects of economic behaviour such as learning and tacit
knowledge and attempt to trace their flows. Shifts in knowledge from the ma
nufacturing to the service sector are shown to be important and related to
previous work which demonstrated the importance of knowledge intensive busi
ness services for both output and productivity in manufacturing. J24, J44,
