Pakistan’s social protection system isstill in a nascent stage of development and so is thecountry’s fiscal and institutional architecture forinter-governmental relations. In particular, the implicitdevolution of social protection and related functions in theeighteenth constitutional amendment in 2010 has created alevel of uncertainty and certain lack of consensus about thedefinitive roles of federal versus provincial governments inproviding social protection to the population. This note isintended to contribute to informed debates about the futureof federalism and social protection in Pakistan.Itdescribes key features of the ways in which maturefederations have organized their social protection sectorand summarizes possible implications for Pakistan. Drawingon the descriptions on how social protection functions aredistributed across levels of government in ten relativelymature federations (including South Africa which isconstitutionally a unitary state but is highly decentralizedin expenditure assignment), this discussion note is intendedas merely one type of input for policy-makers in Pakistan toconsider how best to organize the social protectionfunctions across levels of government in the country’sevolving inter-governmental relations.
