The authors assessed whether livelihood interventions integrated with HIV and AIDS care and treatment programmes share a clearly elucidated causal pathway to impact, and examined their service delivery and utilisation plans to realise intended impacts on food security. They conducted multiple...

Impact evaluations, whether of aid, development interventions or policy interventions, help hold donors and policy makers accountable for promises made and provide a means to legitimise recommendations for future interventions. Quantitative approaches are the order of the day but do not fully...

The authors provide evidence for intermediate and long-term effects of a large scale intervention that focuses on quality of nutritional and child-care inputs during the early stages of life. Their empirical strategy uses a combination of difference-in-difference and weighting estimators in a...

This paper is the protocol for a synthetic review of microfinance. The protocol describes the objectives and scope of the review, the search strategy, inclusion criteria, coding, and synthesis options.

Among active labour market programmes, job training is popular in Latin America as an attempt to help the labour market insertion of disadvantaged youth, and also as a way of providing skills to low-income groups to enable them to deal with the challenges of globalisation. This paper summarises...

This paper is an impact study of key short- and long-run effects of the Danida supported Mymensingh Aquaculture Extension Project (MAEP) in Bangladesh, applying different matching and double difference estimators. Results are mixed. First, the paper finds a positive short-run impact on pond...

Understanding about what constitutes development effectiveness requires elaboration in order for evidence to add greater value. Development in the twenty-first century is often complicated, if not complex, and correspondingly is most likely to be achieved through diagnostic, contextual...

Very few of the (many) aid-financed rural road projects in developing countries have been the subject of rigorous impact evaluations. Assessing the welfare impacts of rural roads poses a number of problems, with implications for data collection and evaluation methods. This paper surveys the...

Understanding the efficacy of development projects requires not only a plausible counterfactual but also an appropriate match between the shape of impact trajectory over time and the deployment of a corresponding array of research tools capable of empirically discerning such a trajectory. At...

This article reviews recent Norwegian aid evaluations with a mandate to study impact, and assesses how the evaluators establish causal effects. The analytical challenges encountered in the seven studies reviewed are: (1) the Terms of Reference ask for evidence of impact where this is not...
