Labor Market Modeling and the Urban Informal Sector: Theory and Evidence
The purpose of this chapter is to assess the compatibility between theoretical models of the urban informal sector (UIS) and empirical evidence on the workings of that sector in the context of developing countries’ labour markets. The major point is that, although the UIS is an excellent idea which has served us well in the 1970s and 1980s, there is a need in the next round of research to refine the terminology and the models in light of empirical findings which have come to the fore in the interim. Wage employment or self-employment in small-scale units may be better than or worse than employment in the formal sector. This is not a new point: diversity of earning opportunities and other job characteristics within the informal sector has long been noted. But only recently has this view come to the fore.
