This paper investigates whether conditional cash transfer (CCT) programmes that include health and nutrition components improve health and nutritional outcomes, and if so, which components of the programmes, or combination thereof, are important in achieving these improvements. Using evidence...

A central objective for the UK Department for International Development (DFID)-funded research on renewable natural resource systems has been that the research commissioned results in significant positive developmental impacts. This paper examines how the DFID-funded Fisheries Management Science...

Data from a controlled randomised trial are used to estimate the effect of Mexico's conditional cash transfer programme, Oportunidades, on birth outcomes, and to examine the pathways by which it works. Birth weights average 127.3 grams higher, and low birth weight incidence is 44.5 per cent...

The authors use a randomised evaluation to examine the effect of a conditional cash transfer programme on grade progression in Nicaragua from 1999 to 2003, putting the spotlight on initial supply-side conditions and the extent to which they conditioned programme effectiveness. Their principal...

Substantial and increasing amounts of funding are available for countries to undertake climate change interventions. This article argues that to ensure effective allocation of these resources, the selection and design of climate change mitigation and adaptation interventions should be based on...

Rarely have researchers explored the distribution of a programme's effects in a population, tending to focus on unidimensional measures of impact instead. This can mask heterogeneity of effects, making it difficult to identify subsets of the population for whom impacts might differ from a...

This article presents a synthetic review of impact evaluations examining the effectiveness of community-driven development (CDD) and curriculum interventions in improving social cohesion in sub-Saharan Africa. The review found weakly positive impacts of CDD and curriculum interventions on social...

This paper presents impacts of the pilot conditional cash transfer programme in Paraguay. The choice of outcomes of interest is based on the work developed by the family counselling component undertaken by social workers. Propensity score techniques are used to deal with the problem of...

There is growing interest in impact evaluation in the humanitarian and development sectors. Several recent reports have identified post-disaster impact evaluation (PDIE) as a particular challenge and galvanised interest in pushing the field forward. This paper reviews existing work, synthesises...
