The 2030 Agenda for Sustainable Development promotes multi‐stakeholder partnerships (MSPs) as a means of implementation while at the same time putting renewed focus on the need for national‐level ownership and implementation. Despite the fact that an ever growing body of literature on the merits and drawbacks of MSPs delineates several success conditions for partnerships, efforts to translate this knowledge into national‐level meta‐governance for MSPs remain marginal to date. This study outlines the benefits the literature alleges for such “meta‐governance” frameworks, before it uses a country‐level study with a series of stakeholder interviews to take a closer look at national‐level context conditions and lessons learned with regard to two water partnerships in Kenya. Our findings suggest that to date the existing meta‐governance for partnerships in Kenya is rather weak and fragmented. Yet respondents support the view that MSPs could benefit from such a framework, in particular regarding local ownership of MSPs and the potential to scale successful cases.

In this paper, we comprehensively examine the effects of the Great Recession on child poverty, with particular attention to the role of the social safety net in mitigating the adverse effects of shocks to earnings and income. Using a state panel data model and data for 2000 to 2014, we estimate the relationship between the business cycle and child poverty, and we examine how and to what extent the safety net is providing protection to at‐risk children. We find compelling evidence that the safety net provides protection; that is, the cyclicality of after‐tax‐and‐transfer child poverty is significantly attenuated relative to the cyclicality of private income poverty. We also find that the protective effect of the safety net is not similar across demographic groups, and that children from more disadvantaged backgrounds, such as those living with Hispanic or single heads, or particularly those living with immigrant household heads—or immigrant spouses—experience larger poverty cyclicality than those living with non‐Hispanic white or married heads, or those living with native household heads with native spouses. Our findings hold across a host of choices for how to define poverty. These include measures based on absolute thresholds or more relative thresholds. They also hold for measures of resources that include not only cash and near‐cash transfers net of taxes but also several measures of the value of public medical benefits.  相似文献
