Value is a critical concept in economics and philosophy. Economics is a discipline concerned with resource allocation informed by the value placed on alternative uses of those resources. In welfarist economics, value is taken as the strength of preference for a good or service (Brouwer et al., 2008). In that paradigm, strength of preference can… Continue reading The intrinsic and instrumental value of water & sanitation
Summary: the severity of climate impacts on WASH services is uncertain. “Low-regrets” investments or interventions are those which generate net economic benefits under a range of the most plausible scenarios of climate impact severity. The concept is explored in Figure 1, which illustrates relationships between net benefits and the severity of climate impacts for different… Continue reading Adapting WASH services to climate change – the “low-regrets” principle and benefit-cost analysis
Figure 1: Transformative in respect of what? This post summarises a note I have drafted on the definition of "transformative WASH", available here, with references. There has been a lot of talk about “transformative” WASH since the WASH-B, SHINE and MapSan results came out. I have previously written about those results here. The argument runs… Continue reading What is transformative WASH?
My colleague Seungman Cha has a paper out this week, which I co-authored with him and others. It’s a trial-based cost-benefit analysis (CBA) of a community-led total sanitation (CLTS) intervention in rural south-western Ethiopia. We estimated intervention delivery costs from financial records and recurrent costs from the trial's surveys. All outcome data are from the… Continue reading New paper – trial-based cost-benefit analysis of a CLTS intervention in Ethiopia
[I was chuffed to be joint winner in the ESRC 'Better Lives' writing competition with the below piece intended for a general audience. The Guardian published an abridged version. Deadlines are 80% of writing, for me at least... so I would recommend competitions like this for forcing oneself to write to a hard deadline for public… Continue reading Better lives with better toilets – SanQoL translated for public engagement
Introduction Since investment options are always compared under a budget constraint, economic evaluation aims to inform unavoidable decisions and support allocative efficiency. Various economic evaluation methods (such as cost-effectiveness analysis and cost-benefit analysis) compare costs and consequences of alternative interventions. Improvements in sanitation can impact on health, and it is typically health outcomes such as averted… Continue reading Using the concept of ‘sanitation-related quality of life’ (SanQoL) to measure what is valued by users
Today I attended not one, but two, seminars on CLTS. The first was Britta Augsburg presenting results of a recent cRCT of a WaterAid CLTS intervention in Nigeria (at LSHTM). The second was Dale Whittington reflecting on CLTS trials in the last few years and his recent CBA paper incorporating their results (at Oxford). A… Continue reading CLTS, targeting and economic performance – reflections on two seminars
