3 HYPOTHESES ON THE BRAZILIAN SERVICE SECTOR

Three hypotheses on services, the Gershuny effect, the externalisation of producers services and the macroeconomic equation for the services share in employment, are tested with Brazilian data. The first two sh ow trends similar to those in the developed economies, but, in the las t one, findings are affected by consideration of the underground econo my. The results suggest a dual character for Brazilian services: an in formal, labour intensive group of sectors, present in the large metrop olitan areas, coexists with a formal, less labour intensive one, where producers' services are probably predominant. These groups will respo nd differently to a greater trade liberalisation.
