The role of cash transfers in reducing poverty and vulnerability

Purpose and rationale for review

This impact review will assess the results that DFID has achieved with its cash transfer (CT) programmes, and the extent to which these results are likely to be sustainable. The review will probe the credibility of DFID’s results claims and assess their significance. It will assess DFID’s use of and addition to the evidence of CTs contribution to reducing poverty and vulnerability. Value for money of DFID’s CT programmes will also be examined.

The review will provide insight into whether DFID’s CT portfolio represents a credible response to target 1.3 of the Sustainable Development Goals, which is to ‘implement nationally appropriate social protection systems and measures for all, including floors, and by 2030 achieve substantial coverage of the poor and the vulnerable’.

Type of review

This portfolio was chosen for an impact review because it is mature enough to have generated a substantial amount of results data. There is also a large body of evidence of what works available in the literature. In impact reviews, ICAI conducts a thorough assessment of the validity of DFID’s results claims and of the significance of a portfolio’s development impact. This review also explores the quality of the systems that DFID uses to capture evidence, and whether the portfolio is using this and other evidence to maximise its results over time.

Scope

This review examines the provision of CTs for the purposes of reducing poverty and vulnerability. Both terms are interpreted widely to do justice to the range of DFID’s CT objectives, which includes those related to schooling, health, nutrition, resilience and women’s empowerment. The review also examines DFID’s support to national social protection systems and programmes. Most of DFID’s system support relates to CT delivery systems. It is a portfolio review covering the period since the beginning of DFID’s Results Framework 2011 (DRF)¹. The review will also take account of elements of previous CT work undertaken, insofar as they helped to shape CT work done in the review period.

CTs are used increasingly as a form of humanitarian assistance. We hope to address humanitarian cash transfers in the future, but have excluded them from the scope of this review as our primary interest is in the development of sustainable national social protection systems.

DFID provided us with a list of 28 development programmes that focused on CTs during the 2011-2015 review period,² plus its current portfolio. Of these, 19 reported results against DFID’s DRF indicator on CTs, which is the ‘number of people benefiting from DFID-supported cash transfer programmes’. This indicator is grouped under the DRF pillar of ‘poverty, vulnerability, nutrition and hunger’, and DFID’s target is to reach six million people in at least one of the years of the review period. Of the other nine programmes, six are limited to providing technical assistance and other forms of systems strengthening support to social protection programmes and/or systems. Two programmes are too recent to be included in the DRF results, and the results of one programme are captured under a different DRF pillar. These 28 programmes provide the sampling frame for this review (hereafter ‘the portfolio’).

The review will look in particular at DFID’s achievements in two areas:

• The impact of CT programmes on CT recipients, their households and communities.
• The development of sustainable national social protection systems. DFID’s work may have contributed to building the capacity, scale of coverage, scalability in response to shocks, targeting or inclusiveness of such systems. This may have been achieved by establishing a supportive policy and legal environment, attracting national government resources and building broad political backing.

Background

The importance of reliable social protection systems that reach the poorest and most vulnerable people and communities was underscored at the Addis Conference on Financing for Development in July 2015.³ It has been adopted as target 1.3 for achieving Goal One of the Global Goals.⁴ The commitment to ‘leave no one behind’, which is embedded within the Global Goals and endorsed by DFID, also adds weight to the social protection agenda.

This formal high-level recognition comes at a time when the volume and reach of CT (an important component of the social assistance part of social protection – see Figure 1)⁵ is growing fast in both low and middle-income countries.

DFID’s support for social protection has focused on CTs. Following the 2006, 2008 and 2011 White Papers, but without an explicit CT strategy, DFID’s CT contributions have grown from £53 million in 2005 to an annual average of £219 million over the review period.⁶ This equates to 2.6% of DFID’s overall spend in this period (2010/11-2014/15 figures), which funded operations in 19 countries. Most of this funding directly financed the delivery of CTs, but there was also a significant allocation to technical assistance and systems-building work to improve national CT and wider social protection systems.

DFID is a major contributor to CT-related work of the multilateral development banks, the European Commission and the UN (not covered in this review), and has played a significant role in the funding, commissioning and dissemination of CT-related research and evaluation. Over the review period, DFID’s research plans prioritised the development and promotion of strong monitoring and evaluation (M&E) practices; the embeddedness of M&E within national strategies for collecting and analysing socio-economic data; the strengthening of cost-benefit analysis to allow for an effective comparison across different instruments and design options; and tackling frontier issues in research on CTs. In response to changing priorities of DFID and its partners, these frontier issues changed over the course of the 2011-2015 period and included CT application in fragile and conflict-affected contexts, the role of social protection in building effective states, financial inclusion and the role of social protection in responding to crises.

Theories of change

DFID does not have an overall theory of change for its CT or wider social protection portfolios. Instead it develops theories of change for individual programmes, on the basis of national host government and DFID priorities.

A 2015 literature review drew on several of DFID’s programme-level theories of change. It presented one that is neither final nor comprehensive, but that does help to understand some of DFID’s common thinking underpinning its CT work.

The starting point of this theory of change is a framework that lists livelihood-related constraints and enablers at household, local and national level. At individual and household level, CTs cause or contribute to three sequential ‘orders of outcomes’: first-order outcomes such as ‘expenditure on education’; second-order outcomes such as ‘school enrolment, attendance and retention’; and third-order outcomes such as ‘school learning, performance and progression’. The theory states that these outcomes are facilitated by CTs through household-level changes in time and risk preferences, household dynamics and gender relations.

At the community level, the theory of change states that a system of CTs can cause or contribute to changes in local labour markets and the economy, and in social networks.⁷ The aggregate level results are ‘poverty and inequality reduction; productivity and growth; social relations and cohesion’.

The framework acknowledges that all these results are influenced by design and implementation factors, such as the level of transfers, associated conditionalities, targeting, payment systems, links to complementary interventions and social accountability mechanisms.

This theory of change reflects some of the thinking behind several of DFID’s programme-specific theories of change. In addition, some programmes have theories of change that focus on the development of national social protection systems. Others have incorporated CT and the national social protection system development within bigger change processes that lead to increased well-being for particularly disadvantaged populations.

Existing evidence

There is a substantial and growing empirical body of evidence related to social protection in general and to the impact of CT in particular. Much of the research is publically available and has been captured in a number of literature reviews.⁸ The latest – a forthcoming Cash transfer rigorous literature review from ODI – identifies 199 credible studies.⁹

From 1990 to 2010, most evidence came from Latin America and the Caribbean. However, the rapid growth of CT programmes in Africa in the past five years has changed this. This is set to continue as CT programmes and systems in Africa continue to generate evidence.

The evidence suggests that CTs can have a range of positive impacts on school enrolment and attendance, use of prenatal and postnatal health care, children’s physical development, and food security, income and productivity. There is compelling evidence to show that the size and coverage of transfers, and the quality of targeting, are key choices affecting impact. However:

• There is some evidence of negative impact as well (eg CT programmes increasing spousal abuse and child abuse and neglect).
• The strength of evidence varies considerably across types of impact. In part, this reflects the changing objectives of programmes implemented since the 1990s, as well as the developing interests of development agencies, academics and national governments. By far the largest number of impact studies examines savings, investment and production, as well as changes to income poverty. Fewer studies and evaluations look at the design and implementation features of programmes that helped to create such impacts, or at targeting mechanisms or levels of accountability in CT programmes.¹⁰

Review questions

The review is built primarily around the OECD-DAC evaluation criteria of impact and sustainability. It will consider the following questions and sub-questions:

Q1: Impact: To what extent have DFID’s CT programmes contributed to reductions in poverty and vulnerability?

Q1.1: To what extent has DFID ensured maximum value for money for its CT programming?
Q1.2: How well has DFID made use of and contributed to evidence on what works to enhance the impact of CT programmes?

Q2: Sustainability: To what extent does DFID maximise the sustainability of its impact?

Q2.1: How well is DFID ensuring that its work has maximum and sustained impact on CT recipients?
Q2.2: How successfully is DFID supporting the development of sustainable, nationally-owned social protection systems?

Core ICAI issues

As this review explores the impact and sustainability of cash transfer programmes and social protection systems as well as the targeting of development programmes on the extreme poor and marginalised, it is closely linked to the ICAI theme of ‘leaving no-one behind’. In addition, the review explores two core ICAI issues.

1. Approaches to programme delivery. This review will provide insights into:
   • The manner in which DFID uses theories of change, data and contextual analyses to identify programmatic entry points, select delivery channels, and shape the design, implementation and evaluation of programmes.
   • The nature of DFID’s guidance for and practice of its programme cycle management, and programme implementation, support and learning.
2. Quality and use of evidence to enhance development impact. As per review question 1.1, this review will provide insight into the manner in which DFID makes use of and contributes to evidence on what works to enhance the impact of a programme portfolio.

Overview of methodology

Four main methodological elements will jointly provide the data and insights required to answer the review questions at both programme and portfolio level (see Figure 2). This section covers them sequentially.

Figure 2 shows how the different elements of the methodology interact. The desk reviews provide broad insight into how CT programmes are designed and managed so as to maximise impact, sustainability and value for money. The country case studies allow for in-depth exploration of CT programming, in particular national contexts, to gain insight into how CT fits within broader national poverty reduction strategies and other programming. They also assess DFID’s contribution to building sustainable national systems. The literature review and external interviews provide an external perspective, to challenge DFID’s approaches and choices. Together, these methodological elements allow for an assessment of the three levels of analysis: 1. a review of a sample of CT programmes; 2. a review of the CT portfolio as a whole; 3. an assessment of the way in which this portfolio is embedded in higher DFID agendas. We present these methodological elements in turn.

1. Desk reviews

These consist of DFID interviews and a review of documents such as business cases, logframes, baseline studies, political economy analyses, annual reviews, project completion reports and independent evaluation reports. We will capture data and insights in a review assessment framework that is grounded in the review questions, and analyse DFID’s views on CT-related approaches, choices, work and results. The desk reviews will contribute to each of the three levels of analysis. Specifically:

A review of a sample of CT programmes. These programme desk reviews focus on the programmes’ impact on poverty and vulnerability and other selected objectives and on the likely sustainability of this impact.¹¹ In addition, we will assess issues such as the use of and contribution to data, evidence and knowledge; the causalities assumed in implicit and explicit theories of change; learning and reporting; and the guidance behind and practice of the management of the various elements of the programme cycle. We will review 15 programmes, covering approximately a third of DFID expenditure of the CT programme portfolio that DFID has provided us (see section 11 for the sampling approach).

A review of the CT portfolio as a whole includes:

• Choices, trends and current practice around strategic thinking, theories of change, policies and guidance.
• The division of responsibilities for managing the portfolio and the staff capacities for doing so.
• Knowledge management and learning systems and processes around CTs, including DFID’s CT-related research portfolio management, the way DFID collects, synthesises and disseminates evidence from internal and external sources on what works, and the way DFID uses this evidence to learn and improve practice.
• The provision of technical support to country offices.
• The guidance around DRF indicators and other results and value for money measurements.

An assessment of the CT portfolio against higher DFID agendas. Through interviews and the comparison of CT and higher-level documents, we will assess the match between choices made in the CT portfolio and DFID’s high-level agendas such as the prioritisation of the rights of girls and women, and the ‘leave no one behind’ principle.

2. Literature reviews

These reviews will draw on systematic evaluations and syntheses of those evaluations. In combination with the team’s own expertise, these reviews will help to assess two levels of analysis:

A review of a sample of CT programmes. We will assess the alignment of programme design and modalities with good practice principles; the way programmes use and contribute to CT’s knowledge bank; and the credibility of results claims.

A review of the CT portfolio as a whole. We will assess the way the portfolio aligns with, and contributes to, evolving insights on what works.

3. External interviews

On the basis of an initial list and subsequent snowball sampling, we will conduct interviews with a range of stakeholders from academia, civil society, programme implementers, partner governments, other supporting governments, and multilateral partners. These interviews will add depth and context to the literature reviews. They will ensure that critical voices are heard and that alternative practices are considered. They will also support the contribution analysis by triangulating causal links and by identifying and assessing rival theories that may explain results claimed.

Depending on the stakeholders, these interviews will support the review of a sample of CT programmes, and/or the review of the CT portfolio as a whole. At both levels, these interviews will help to assess DFID’s knowledge contributions and stakeholders’ use of these contributions.

4. Country case studies

We will conduct two country case studies (see section 11 for the selection criteria). The subject of each is DFID’s entire CT-related country portfolio. Both country case studies will provide in-depth insights that expand and complement the review of a sample of CT programmes. The case studies will enable us to:

• Assess the role of country-level CT portfolios within DFID country strategies.
• Assess DFID’s support to national social protection programmes and systems. The assessment includes DFID’s policy advocacy, technical assistance and financial support to such systems, and a probing into the sustainability and level of national ownership of these systems.
• Test the quality, accountability and results claims of DFID-funded CT programmes.

These country case studies will provide in-depth insights through gaining access to data that are only available locally, and feedback that can only be obtained through face-to-face interviews and discussions. Specifically, these case studies will enable us to:

1. Understand the role of country-level CT portfolios within higher DFID agendas and in-country operational plans. We will also assess where CTs fit within high-level strategies for tackling extreme poverty and marginalisation, such as the SDGs and the ‘leave no one behind’ agendas. We will explore links between CT programmes and complementary interventions.
2. Explore the quality of DFID’s policy advice and technical assistance. As part of a light-touch contribution analysis, we will gather feedback from government counterparts and external observers on the relevance, effectiveness, impact and staging of DFID’s policy advice and technical assistance to support the development of national social protection systems.
3. Probe the sustainability of national social protection systems and the quality of the data that underpin these systems. Through a review of country-specific data and literature, and through interviews with a range of in-country stakeholders, we will explore the robustness of and remaining bottlenecks for sustainable national systems. This will include exploring financial sustainability, the level of political support for sustaining the required resource allocation and the feasibility of the proposed institutional model in the national context. Governance and accountability mechanisms and the adequacy of national poverty statistics in supporting effective targeting of CTs will also be examined. We will assess the extent to which DFID has identified the key shortcomings and to which DFID or other stakeholders are taking credible action to help national governments to address them.
4. Assess the credibility of results claims, issues of inclusiveness, and value for money measurements. On a sample basis, we will:
   • Trace the reported number of CT recipients against the DRF target back to results data from individual programmes, and vice versa.
   • Assess the extent to which DFID has adequate monitoring arrangements in place to verify data reported by its implementers.
   • Explore the validity of programme-specific results claims by triangulating them against stakeholder feedback from non-recipients, recipients and frontline workers, and nationally available data sources.
   • Assess programmes against the ‘leaving no one behind’ principle by examining how programmes manage issues of remoteness and intersectionality (ie the way in which individuals and groups are subject to overlapping and reinforcing vulnerabilities and systems of discrimination).
   • If these analyses exist, validate and check the programmes’ Economy, Effectiveness, Efficiency and Equity analyses, cost-effectiveness analyses and/or cost-benefit analyses, on the basis of DFID’s value for money guidance and considerations of economies of scale.
5. Assess the quality of accountability mechanisms. During visits to CT-receiving communities, in which we will interview CT recipients, non-CT recipients and front-line workers, we will assess the extent to which end-of-pipeline accountability and complaints handling mechanisms are functioning. We will also test the implementation of targeting and CT modalities. This will support the overall analysis on value for money.

Review framework

Four main methodological elements will jointly provide the data and insights required to answer the review questions at both programme and portfolio level (see Figure 2). This section covers them sequentially.

Sampling strategy

The programme sample criteria

The distinct characteristics of each of DFID’s CT programmes confirm that a ‘standard DFID CT programme’ does not exist. To gain insight into DFID’s CT work the review team therefore needs to assess a sample of programmes that is selected purposively to reflect the full spectrum of programme objectives, modalities, support, types and sizes.

Looking across DFID’s CT work, the team identified the most important distinctions among programmes. These were related to the objectives that DFID’s programmes seek to achieve, the modalities used, the types of support that DFID provides, and the range in size of financial support programmes. These characteristics became the sampling criteria.

To avoid conclusions based on outliers, our sample will consist of programmes that together, cover each characteristic at least twice (eg at least two education-focused programmes, at least two conditional CT programmes). The criteria are as follows, with the number of programmes befitting each criterion added between brackets:

Secondary criteria were as follows¹³:

• Implementation period. Programmes that ended before mid-2011 or started after mid-2015 were excluded as they cover an insufficiently meaningful part of the review period.
• Previous UK government assessments. Programmes that have recently been assessed by ICAI, the IDC or NAO were excluded to avoid duplication of efforts.

The result is a sample of 15 programmes that will be subject to a desk review. Four of them will also be covered by a country case study. Together, these 15 programmes cover approximately 63% of DFID’s spend on CTs and approximately 50% of its results towards the DRF.¹⁴ They are as follows:

The country case study criteria

There are 19 countries in which DFID has undertaken CT-related work in the review period. The team considered which of them would be suitable for country case studies. The criteria were that the country portfolio must be sizeable and include both technical assistance and financial support to the national country’s social protection system. It must have been operational for at least a few years and must not have been the focus of a recent UK government review. The team found that:

• DFID does not provide significant system support in Burma, Nigeria, Mozambique, Occupied Palestinian Territories, Yemen and Zimbabwe.
• DFID’s work in Kosovo, Egypt and Vietnam does not include financial support.
• DFID’s programme in Tanzania is too new for analysis.
• The cash transfer component in Nepal’s multi-component programme is modest.
• Other UK government reviews have recently visited Ethiopia, Pakistan and Zambia.

Five countries remained viable options for country case studies: Bangladesh, Ghana, Kenya, Rwanda and Uganda. Of these, the team opted to visit Bangladesh, as it has by far the largest CT portfolio of these five countries (irrespective of the size unit used). The team will visit Rwanda, as it has had the longest system development history of the remaining four countries. This provides an opportunity for an in-depth exploration of the review questions concerning the sustainability of national social protection systems. Both country case studies fulfil the key selection criteria. In addition, the different aspects of DFID’s CT programming in each country that would be analysed would also complement each other in helping to cover a wider spectrum of DFID’s CT work, see Figure 3.

Limitations to the methodology

This review has four key limitations.

1. This review will identify but not fill gaps in credible evidence. Significant gaps will affect the robustness of the review’s findings. This review was not built into any CT programme’s design, and does not generate substantial primary data to test the causal link between interventions and results. Instead, this impact review draws primarily on existing data. It could potentially mitigate this limitation by conducting primary research – but any such research will be small-scale, and the review team will only consider it in case of data deficits that are both serious and easy to fill.
2. Findings may not be easy to generalise across DFID’s CT portfolio. There is no ‘standard’ CT programme. The sample selected for this review covers at least two programmes in each category of programmes (see the section on the review’s sampling strategy) but none of these sets of two can be assumed to be truly representative.¹⁵ (They are, however, sufficient to enable us to identify recurrent patterns in the portfolio that influence delivery of impact.) The review will mitigate this limitation by considering key findings from the review of the sampled programmes in the light of key findings from the wider CT literature. It also aims to provide a typology of what worked well, where and why.
3. The assessment of the success with which DFID is supporting the development of social protection systems is likely to be biased towards the effects of financial assistance and the ‘hard’ side of DFID’s technical assistance. The effects of financial support and assistance with, for example, legislative support or support with the system architecture, can probably be captured with reasonable rigour. However, a contribution analysis of DFID’s advocacy and influencing work is challenging, especially in a complex multi-stakeholder context, given that programme teams are unlikely to have collected data on influencing systematically. The evidence of DFID’s role in reaching trigger, tipping and turning points – which could potentially be among DFID’s biggest achievements – can not be captured in real time, and therefore become lost or unverifiable. The team will manage this by assessing the available data, and focusing on the causal links for which the data are likely to be most robust.
4. Our assessment of the sustainability of impact will, at least in part, be based on theory and evidence from comparable, older programmes. Where possible, sustainability assessments will be based on post-intervention data. In most cases, this data will not (yet) exist, and we will therefore be required to make predictions based on whether programmes are giving sufficient evidence-based attention to sustainability in their design and implementation.

Ethical considerations

This review will use an appropriate, proportional and sound set of methods. It will use them in close consultation with DFID in order to ensure cost effectiveness by selectively testing but not duplicating work that DFID has already done.

The review team is guided by the OECD DAC Quality Standards for Development Evaluation. The team will undertake all interviews on the basis of informed consent and will ensure that the opinions and information incorporated in the review report will not be traceable to individuals, unless the interviewer has obtained prior explicit consent of the individuals in question.¹⁶

The perspectives of CT recipients will be collected indirectly, through key stakeholder interviews and by drawing on secondary sources. These perspectives will substantially inform the review findings and the team will ensure that key CT recipients’ perspectives are voiced in the review report. In addition, the team will conduct a number of interviews with CT recipients and non-CT recipients. When conducting these interviews, the team will respect cultural sensitivities and will ensure that it seeks a diversity of perspectives, with an inbuilt bias towards those who are often invisible and unheard. In the unlikely event that the team interviews children, it will conduct these interviews in line with UNICEF’s child-focused ethical evaluation guidelines.

Research tools

We will develop relevant research tools in the early stages of the review. These include:

• A mapping of DFID and external stakeholders for interview and consultation.
• Interview guides for key stakeholders, indicating relevant areas to explore.
• A review framework for desk reviews that allows for a comparison and aggregation of findings.
• Country case study frameworks covering contextual analysis, list of key stakeholders, sampling of delivery partners and programmes, and detailed plans for field research (to be completed three weeks in advance of the country visit).

Quality assurance and peer review

This review will be carried out under the guidance of ICAI Lead Commissioner, Alison Evans. The Peer Commissioner is Tina Fahm. The quality of the review will be assessed by Pam Vallance, Review Unit, ICAI Secretariat, using OECD DAC evaluation standards.

This review will be externally peer reviewed by Professor Wendy Olsen, a statistician and professor in Socio-Economics at the School of Social Sciences of the University of Manchester. Professor Olsen has reviewed a draft of the Approach Paper (and her feedback has been incorporated in this final version) and will review:

1. The thematic overviews of the various types of interviews that the team will conduct, once the team has gained sufficient insight in DFID’s CT work to develop these overviews.
2. The sampling principles that will guide the country visits, once the team has formulated them. This is to ensure it is based on as much team insight as possible.
3. The draft report.
