This report is a description of the research carried out by Development Workshop, funded by IDRC, between September 2007 and June 2009. The report accompanies the reports of the three components of the research. During this 27 month period, DW has carried out its proposal to expand and build upon its experience of both sector-specific and broad baseline research to develop a comprehensive and cross-sector integrated study of the Angolan informal economy. Specifically this research programme has aimed to: significantly increase quantitative and qualitative understandings of important sectors of the informal economy; conduct a literature review of all previous research and policy documents on the informal economy in Angola and a selective review of international research relevant to the three themes developed in the current programme; carry out a cross-sector study that documented the strategic relationships, interactions, and inter-dependencies among different sub-sectors of the informal economy; foster knowledge-based approaches to public policy making.
