Competitive and Segmented Informal Labor Markets
It has been recently argued that the informal sector of the labor market in a developing economy shows a dual structure with one part of it being competitive to the formal sector and another part being the result of market segmentation. To test this hypothesis we formulate an econometric model which allows for a heterogeneous informal sector with unobserved individual a?liation and which takes into account selection bias induced by the employment decision of individ- uals. Our test results for the urban labor market in C^ote d'Ivoire indeed show existence of both competitive and segmented employment in the informal sector.
