Book Description
Recall biases in retrospective survey data are widely considered to be pervasive and have important implications for effective agricultural research. In this paper, we leverage the survey design literature and test three strategies to attenuate mental anchoring in retrospective data collection: question order effects, retrieval cues, and aggregate (community) anchoring. We embed a survey design experiment in a longitudinal survey of smallholder farmers in Malawi and focus on anchoring bias in maize production and happiness exploiting differences between recalled and concurrent responses. We find that asking for retrospective data before concurrent data reduces recall bias by approximately 34% for maize production, a meaningful improvement with no increase in survey data collection costs. Retrieval cues are less successful in reducing the bias for maize reports and involve more data collection time, while community anchors can exacerbate the bias. Reversing the order of questions and retrieval cues do not help to ease the bias for happiness reports.

Book Description
Coffee is a growth market. Current estimates indicate that global coffee production (in volume) has increased by more than 60% since the 1990s. Coffee is produced by around 25 million farmers, which are mainly smallholders in developing and least developed countries, and over 70% of the coffee produced is exported, resulting in about 20 billion US dollars annual foreign exchange earnings (ICO, 2020). COVID-19 represented a severe joint supply and demand shock to the global coffee sector, particularly during the first months after the start of the pandemic. As noted by Hernandez et al. (2020), the coffee industry experienced important disruptions downstream the value chain, including the functioning of key export infrastructure and international shipping, which combined with local currency devaluations and volatile coffee prices, which resulted in significant challenges for coffee growers, farm workers, and traders.

Book Description
Self-reported retrospective survey data is widely used in empirical work but may be subject to cognitive biases, even over relatively short recall periods. This paper examines the role of anchoring bias in self-reports of objective and subjective outcomes under recall. We use a unique panel-survey dataset of smallholder farmers from four countries in Central America collected over a period of three years. We exploit differences between recalled and concurrent responses to quantify the degree of mental anchoring in survey recall data. We assess whether respondents use their reported value for the most recent period as a cognitive heuristic when recalling the value from a previous period, while controlling for the value they reported earlier. The results show strong evidence of sizeable anchoring bias in self-reported retrospective indicators for both objective measures (income, wages, and working hours) and subjective measures (reports of happiness, health, stress, and well-being). We also generally observe a larger bias in response to negative changes for objective indicators and a larger bias in response to positive changes for subjective indicators.

Book Description
Ethiopia is currently embroiled in a large-scale civil war that has continued for more than a year. Using unique High-Frequency Phone Survey (HFPS) data, which spans several months before and after the outbreak of the war, this paper provides fresh evidence on the ex durante impacts of the conflict on the food security and livelihood activities of affected households. We use difference-in-differences estimation to compare trends in the outcomes of interest across affected and unaffected regions (households) and before and after the outbreak of the civil war. Seven months into the conflict, we find that the outbreak of the civil war increased the probability of moderate to severe food insecurity by 38 percentage points. Using the Armed Conflict Location and Event Data (ACLED) on households’ exposure to violent conflict, we show that exposure to one additional battle leads to 1 percentage point increase in the probability of moderate to severe food insecurity. The conflict has reduced households’ access to food through supply chain disruptions while also curtailing non-farm livelihood activities. Non-farm and wage related activities were the most affected by the conflict while farming activities were relatively more resilient. Similarly, economic activities in urban areas were much more affected than those in rural areas. These substantial impact estimates, which are likely to be underestimates of the true average effects on the population, constitute novel evidence on the near-real-time impacts of an on-going civil conflict, providing direct evidence on how violent conflict disrupts the functioning of market supply chains and livelihoods activities. Our work highlights the potential of HFPS to monitor active and large-scale conflicts, especially in contexts where conventional data sources are not immediately available.

Book Description
New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

Book Description
In Cooking Data Crystal Biruk offers an ethnographic account of research into the demographics of HIV and AIDS in Malawi to rethink the production of quantitative health data. While research practices are often understood within a clean/dirty binary, Biruk shows that data are never clean; rather, they are always “cooked” during their production and inevitably entangled with the lives of those who produce them. Examining how the relationships among fieldworkers, supervisors, respondents, and foreign demographers shape data, Biruk examines the ways in which units of information—such as survey questions and numbers written onto questionnaires by fieldworkers—acquire value as statistics that go on to shape national AIDS policy. Her approach illustrates how on-the-ground dynamics and research cultures mediate the production of global health statistics in ways that impact local economies and formulations of power and expertise.

Book Description
Governments and international development partners investing over $40 USD billion a year in school meals have shown interest in linking these programs with agriculture sector development, through what has become known as “Home-Grown” school feeding (HGSF). Nevertheless, evidence on the effectiveness of HGSF and agriculture is limited. This article reports on the findings of a three-year cluster randomized trial implemented in 58 districts of Ghana including a panel of 1,668 households. Communities were randomly assigned to 1) standard school meals; 2) HGSF or 3) control with no intervention. Post-intervention, the caterer-level analysis highlighted major challenges related to delayed program disbursements, resulting in a mismatch between budgeted and actual caterer outlay on food purchases per pupil equivalent to approximately 50% of the budgeted per child per day allocation. For caterers, by far the largest procurement channel was through traders, though there is evidence that HGSF may have increased the share of value purchased directly from smallholders. We find no strong evidence that the school feeding program or HGSF affected smallholders market structure, farm, non-farm and household income. When interpreting these null results, it is important to consider the findings of two parallel studies that showed positive effects of this national program on school children’s learning, cognition, and nutrition outcomes. The national program can still be considered as an effective social protection strategy with multiple objectives, even if the agriculture objectives remain aspirational.

Book Description
Poverty and Shared Prosperity 2016 is the first of an annual flagship report that provides a global audience comprising development practitioners, policy makers, researchers, advocates, and citizens in general with the latest and most accurate estimates on trends in global poverty and shared prosperity. This edition documents trends in inequality and identifies recent country experiences that have been successful in reducing inequalities, provides key lessons from those experiences, and synthesizes the rigorous evidence on public policies that can shift inequality in a way that bolsters poverty reduction and shared prosperity in a sustainable manner.Specifically, the report addresses the following questions: •What is the latest evidence on the levels and evolution of extreme poverty and shared prosperity?•Which countries and regions have been more successful in terms of progress toward the twin goals and which are lagging behind? •What does the global context of lower economic growth mean for achieving the twin goals? •How can inequality reduction contribute to achieving the twin goals?•What does the evidence show concerning global and between- and within-country inequality trends?•Which interventions and countries have used the most innovative approaches to achieving the twin goals through reductions in inequality? The report makes four main contributions. First, it presents the most recent numbers on poverty, shared prosperity, and inequality. Second, it stresses the importance of inequality reduction in ending poverty and boosting shared prosperity by 2030 in a context of weaker growth. Third, it highlights the diversity of within-country inequality reduction experiences and synthesizes experiences of successful countries and policies, addressing the roots of inequality without compromising economic growth. In doing so, the report shatters some myths and sharpens our knowledge of what works in reducing inequalities. Finally, it advocates for the need to expand and improve data collection—for example, data availability, comparability, and quality—and rigorous evidence on inequality impacts in order to deliver high-quality poverty and shared prosperity monitoring.
