David Miliband and Ravi Gurumurthy cite 3ie impact evaluation database in a Foreign Affairs article on improving humanitarian aid
In this Foreign Affairs article, David Miliband and Ravi Gurumurthy from the International Rescue Committee argue that evidence-based solutions create a major opportunity for donors and agencies to make humanitarian aid more effective. They cite the 3ie impact evaluation database as an important source for getting evidence on the impact of development interventions on tackling poverty in low- and middle-income countries and make a case for conducting more impact evaluations in fragile contexts.

Ruth Levine, director of global development at Hewlett Foundation and member, 3ie board of commissioners, interviewed by SciDev.Net
"To stay relevant in a changing world, aid agencies must focus their resources on meeting low-income countries’ growing demand for data that can help them assess the impact of development activities," Ruth Levine, director of global development at Hewlett Foundation told SciDev.Net (29 October 2014) during the 3ie Evidence Week in London, 13-17 October.

3ie is happy to announce the winners of the Impact Evaluation Repository challenge. In the last two months, we received 97 study submissions from more than 25 people.
Of the 97 studies submitted, 63 were eligible impact evaluations and were immediately added to the Impact Evaluation Repository. Of these, 32 studies** (and one correction) were published before 2013 and should have been found in our last search (thus are eligible for our $10 Amazon.com gift certificate prizes).
These studies are invaluable in our efforts to improve our systematic search and screening protocol and provide the international development community with the most up-to-date, published impact evaluation evidence available.
We would like to sincerely thank the following people for sending their approved impact evaluation studies to the Impact Evaluation Repository. As always, we encourage you to send any published impact evaluations to firstname.lastname@example.org.

This paper by Thomas de Hoop, Luuk van Kempen, Rik Linssen & Anouka van Eerdewijk in the Feminist Economist looks at the relationship between participation in women's self-help groups, women's autonomy and subjective well-being in Odisha, India.
The findings suggest that while self-help group membership results in positive effects on women's autonomy, there is also evidence of negative effects on women's subjective well-being in villages with relatively conservative gender norms. Qualitative research suggests that this negative effect is associated with social sanctions after the transgression of gender norms.

Do conditions moderate the effects of cash transfer programs? Preliminary findings from a systematic review
The preliminary findings from the systematic review indicates that both conditional cash transfer (CCT) and unconditional cash transfer (UCT) programmes improve school enrolment: 23% in the case of UCT programmes and 41% for CCT programmes.
An impact evaluation of the loans offered by Compartamos, the largest microlender in Mexico shows that loan recipients grew their business revenues and expenses, were happier, more trusting, had greater household decision power, and were better able to manage liquidity and risk. However, there was little evidence that loans had an impact on building wealth like household income, business profits, or consumption.
The study adds to the evidence that microcredit is generally beneficial, but not necessarily transformative.

In a video interview, Phil Davies talks about the importance of timing for researchers wanting to engage and inform policymakers. He talks about 3ie GapMap as a visual and engaging tool for understanding what is known and what isn't.
In Part 2 of the video, he stresses the importance of physical access, encouraging efforts towards ensuring that policymakers are aware of, and can get hold of, the kinds of evidence that they need to make good decisions.
A DFID guidance note on the best ways to assess evidence in international development. It offers some rules on:
- understanding different types of empirical research evidence
- appreciating the principles of high quality evidence
- considering how the context of research findings affects the way that staff may use them
- understanding how to make sense of inconsistent or conflicting evidence

Theme: What we have learned from 3ie's experience in evidence- based development
Speaker: Howard White
Howard White discusses different designs of randomized control trials and addresses criticisms of RCTs which are mostly argued to rest on misunderstandings of the approach.
The standard approach to policymaking and advice in economics implicitly or explicitly ignores politics and political economy, and maintains that if possible, any market failure should be rapidly removed. This NBER working paper by Daren Acemoglu and James A. Robinson argues why this conclusion may be incorrect.
This CGD Working Paper by Tessa Bold, Mwangi Kimenyi, Germano Mwabu, Alice Ng'ang'a, and Justin Sandefur looks at how a Kenyan education programme proven successful in a randomised controlled trial, failed to have similar outcomes when implemented.

Berk Ozler on the pros and cons of using surveys to measure impact.
"...So, evaluating a large government program using an unrelated routine government survey may be fine (although I suspect that they too will have biases depending on what the respondents think the survey is for, how large, important, and ‘in the news’ the intervention is, etc.), but evaluating your own experiment that aims to change some behavior by asking study participants whether they have changed that behavior is unacceptable."
How can systematic reviews contribute evidence for policy? Blogs on this page take up the debate on conducting and using systematic reviews.
Tracey Koehlmoos, adjunct professor at George Mason University, Washington DC, and adjunct scientist at ICDDR,B blogs on sessions at the Dhaka Colloquium on Systematic Reviews.
"...Perhaps the most controversial session that I have attended so far was provocatively named “Rapid reviews: opportunity or oxymoron?” 3ie deputy director, Phil Davies presented on “rapid evidence assessment” and their place in the pantheon of evidence synthesis efforts aimed at informing policy making. Serious questions remain about rapid reviews being biased compared to systematic reviews—and how the process would even allow the developers of these reviews to recognize any biases. However, Davies pointed out that “all evidence is probabilistic.” ..."
"This discussion paper aims to support appropriate and effective use of impact evaluations in AusAID by providing AusAID staff with information on impact evaluation. It provides staff who commission impact evaluations with a definition, guidance and minimum standards."
3ie recently participated at an IFAD learning event on impact evaluations for environmental and climate change interventions.
William Savedoff blogs on the challenge that impact evaluation poses for organisations. "...Other times, the concerns reflect an unwillingness to clearly state their goals, be explicit about their theories of change, or put their beliefs about what works to an objective test. Yet, this is exactly what is at stake with evaluation: are you willing to be proven wrong?"
"Potential biases can arise when collecting qualitative data, in deciding which questions are asked, in what order, how they are asked and how the replies of the respondents are recorded.
"There can also be biases in how the responses are interpreted and analyzed, and finally which results are chosen for presentation. Of course quantitative data and analysis is also prone to bias, such as sampling bias and selection bias. But methodologies have been developed to explicitly deal with these biases. Indeed evaluation designs are judged on precisely how well they deal with these biases."
