The aim of this paper is to evaluate critically the popular prejudice that
economic development is characterised by a natural and inevitable shift of
economic activity from the informal to the formal sphere which culminates i
n full-employment (the formalisation of work thesis). We show not only that
this end-state has never been achieved in most advanced economies but that
some nations have now moved into a 'post-formalisation' stage of economic
development characterised by informalisation. Drawing upon new empirical ev
idence from Southampton in the UK, the view that informalisation is due to
marginalised populations adopting informal survival strategies out of econo
mic necessity is refuted. Instead, informal work is found to be higher in e
mployed households who conduct such work for mostly non-economic reasons. I
n consequence, we argue that unless it is accepted that societies are movin
g into an era of informalisation and policies embraced which recognise this
shift, then many will be left excluded not only from employment but also f
rom informal coping strategies. (C) 1999 Elsevier Science Ltd. All rights r
