Weller (2008, p. 21), describes labour-market institutions as "mechanisms with differing degrees of formality that establish the rules of behaviour for participants in the labour market". The ultimate goal of labour-market institutions is to generate high-quality employment by means of labour market regulation, unemployment protection systems and active labour market policies (which are not part of social protection per se). To achieve this goal, institutions must meet two objectives: "they must ensure an efficiently functioning labour market, i.e. the optimal allocation of resources, and they must guarantee protection and support for the weakest players in a market characterized by structural inequalities among participants" (Weller, 2008). At the same time, to maintain the coherence of social protection policies there needs to be coordination among the various State institutions, as well as information systems for monitoring their actions and oversight and conflict-resolution mechanisms. For instance, non-contributory social protection programmes are often managed by public social development institutions (such as ministries of social development, social investment funds or specialized programmes).
