The informal sector plays a significant role in Pakistan’s economy as
well as in other developing countries. The role of the informal sector in
solving the unemployment problem of Third World countries has become the
focus of a conceptual and empirical debate in recent years. Most of the
research takes a favourable view of this sector and suggests that it should be
used as a policy instrument for the solution of the most pressing problems of
developing countries, such as unemployment, poverty, income inequalities,
etc. Before proceeding further, we will define the informal sector and
differentiate it from the formal sector. There are various definitions, but the
one given in an ILO report (1972) is generally considered the best. According
to this report, informal sector activities are ways of doing things characterised
by a heterogeneous array of economic activities with relative ease of entry,
reliance on indigenous resources; temporary or variable structure and family
ownership of enterprises, small scale of operation, labour intensive and
adapted technology, skills acquired outside the formal school system, not
depending on formal financial institutions for its credit needs; unregulated and
unregistered units, and not observing fixed hours/days of operation.
