This book was released on 2020-11-21 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Telescoping errors occur if survey respondents misdate consumption or expenditure episodes by including events from outside the reference period in their recall. Concern about telescoping influenced the design of early Living Standards Measurement Study (LSMS) surveys, which used a two-visit interview format to allow a bounded recall. This design fell out of favor although not for evidence-based reasons. Recent guidelines to harmonize food data collection in low- and middle-income countries by using one-week recall increase the relevance of telescoping because errors spread over a shorter period will loom larger. To provide evidence on telescoping, we conducted a survey experiment in Ethiopia, randomly assigning a balanced sample – either a two-visit bounded recall or a single visit unbounded recall. The average value of reported food consumption is 16 percent higher in the unbounded single visit recall relative to the two-visit bounded recall. Put differently, in this experiment, telescoping errors amount, on average, to an entire extra day worth of consumption being included in the report for the last seven days. Most of the error is explained by difference in reporting of spending on less frequently consumed, protein-rich foods, so apparent diet diversity and dietary quality indicators are likely to be overstated when using unbounded recall.

Download or read book Assessing response fatigue in phone surveys: Experimental evidence on dietary diversity in Ethiopia written by Abay, Kibrom A. and published by Intl Food Policy Res Inst. This book was released on 2021-04-30 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic has spurred interest in the use of remote data collection techniques, including phone surveys, in developing country contexts. This interest has sparked new methodological work focusing on the advantages and disadvantages of different forms of remote data collection, the use of incentives to increase response rates and how to address sample representativeness. By contrast, attention given to associated response fatigue and its implications remains limited. To assess this, we designed and implemented an experiment that randomized the placement of a survey module on women’s dietary diversity in the survey instrument. We also examine potential differential vulnerabilities to fatigue across food groups and respondents. We find that delaying the timing of mothers’ food consumption module by 15 minutes leads to 8-17 percent decrease in the dietary diversity score and a 28 percent decrease in the number of mothers who consumed a minimum of four dietary groups. This is driven by underreporting of infrequently consumed foods; the experimentally induced delay in the timing of mothers’ food consumption module led to a 40 and 11 percent decrease in the reporting of consumption of animal source foods, and fruits and vegetables, respectively. Our results are robust to changes in model specification and pass falsification tests. Responses by older and less educated mothers and those from larger households are more vulnerable to measurement error due to fatigue.

Download or read book Impacts of COVID-19 on food security: Panel data evidence from Nigeria written by Amare, Mulubrhan and published by Intl Food Policy Res Inst. This book was released on 2020-08-11 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to quantify the overall and differential impacts of COVID-19 on household food security, labor market participation and local food prices in Nigeria. We exploit spatial variation in exposure to COVID-19 related infections and lockdown measures along with temporal differences in our outcomes of interest using a difference-in-difference approach. We find that those households exposed to higher COVID-19 cases or mobility lockdowns experience a significant increase in measures of food insecurity. Examining possible transmission channels for this effect, we find that COVID-19 significantly reduces labor market participation and increases food prices. We find that impacts differ by economic activities and households. For instance, lockdown measures increased households' experience of food insecurity by 12 percentage points and reduced the probability of participation in non-farm business activities by 13 percentage points. These lockdown measures have smaller impacts on wage-related activities and farming activities. In terms of food security, households relying on non-farm businesses, poorer households, those with school-aged children, and those living in remote and conflicted-affected zones have experienced relatively larger deteriorations in food insecurity. These findings can help inform immediate and medium-term policy responses, including social protection policies aiming at ameliorating the impacts of the pandemic, as well as guide targeting strategies of governments and international donor agencies by identifying the most impacted sub-populations.
Book Synopsis COVID-19 and global food security: Two years later by : McDermott, John
Download or read book COVID-19 and global food security: Two years later written by McDermott, John and published by Intl Food Policy Res Inst. This book was released on 2022-03-07 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two years after the onset of the COVID-19 pandemic, the health, economic, and social disruptions caused by this global crisis continue to evolve. The impacts of the pandemic are likely to endure for years to come, with poor, marginalized, and vulnerable groups the most affected. In COVID-19 & Global Food Security: Two Years Later, the editors bring together contributions from new IFPRI research, blogs, and the CGIAR COVID-19 Hub to examine the pandemic’s effects on poverty, food security, nutrition, and health around the world. This volume presents key lessons learned on food security and food system resilience in 2020 and 2021 and assesses the effectiveness of policy responses to the crisis. Looking forward, the authors consider how the pandemic experience can inform both recovery and longer-term efforts to build more resilient food systems.
Book Synopsis Economic impacts of COVID-19 pandemic in Ethiopia: A review of phone survey evidence by : Hirvonen, Kalle
Download or read book Economic impacts of COVID-19 pandemic in Ethiopia: A review of phone survey evidence written by Hirvonen, Kalle and published by Intl Food Policy Res Inst. This book was released on 2020-08-24 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in most low and middle-income countries, the paucity of timely economic data in Ethiopia makes it difficult to understand the economic impacts of the COVID-19 pandemic. To mitigate this, several organizations have launched phone surveys to gather more information about the crisis. This research report reviews the available phone survey evidence as of mid-August 2020 and identifies knowledge gaps. First, the available evidence suggest that the pandemic has not led to unusually large increases in food prices. However, a case study in the vegetable sector suggests that price dynamics are highly context and crop specific, calling for more comprehensive price monitoring to identify food value chains and areas where food price increases may have been unusually rapid. Second, employment losses have concentrated on informal sector workers while redundancies in the formal sector have been less significant. Third, there is considerable uncertainty about the income, poverty, and food security implications of this crisis. While most households report income losses, the qualitative and subjective nature of these questions meanthat the magnitudes of these losses are unknown. In Addis Ababa, less subjective food security measures indicate only small negative changes in household food and nutrition security. Finally, due to limited access to mobile phones in rural areas, we have imperfect and incomplete information on how this crisis is affecting rural households.
Book Synopsis Food and nutrition security in Addis Ababa, Ethiopia during COVID-19 pandemic: June 2020 report by : Abate, Gashaw T.
Download or read book Food and nutrition security in Addis Ababa, Ethiopia during COVID-19 pandemic: June 2020 report written by Abate, Gashaw T. and published by Intl Food Policy Res Inst. This book was released on 2020-06-16 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: In early June 2020, we called by telephone a representative sample of nearly 600 households in Addis Ababa, Ethiopia to assess income changes and household food and nutrition security status during the COVID-19 pandemic (survey period covering May). This was the second administration of a COVID-19 related survey to these households, following an initial survey conducted in early May 2020 covering the situation of the survey households in April. More than two-third of the households indicated in the second survey that their incomes were lower than expected (up from 58 percent in April) and 45 percent reported that they are extremely stressed about the situation (up from 35 percent in April). Using a pre-pandemic wealth index, we find that less-wealthy households were considerably more likely to report income losses and high stress levels than were wealthier households. Compared to a period just before the pandemic (January and February 2020), indicators measuring food security have significantly worsened but have remained the same since April. During the pandemic, households are less and less frequently consuming relatively more expensive but nutritionally richer foods, such as fruit and dairy products. However, overall food security status in Addis Ababa is not yet alarming, possibly because many households have been able to use their savings to buffer food consumption. As the pandemic is still in an early stage in Ethiopia, it is likely that these savings will not last throughout the pandemic, calling for a rapid scale-up of existing support programs.
Book Synopsis COVID-19 and food security in Ethiopia: Do social protection programs protect? by : Abay, Kibrom A.
Download or read book COVID-19 and food security in Ethiopia: Do social protection programs protect? written by Abay, Kibrom A. and published by Intl Food Policy Res Inst. This book was released on 2020-11-11 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: We assess the impact of Ethiopia’s flagship social protection program, the Productive Safety Net Program (PSNP) on the adverse impacts of the COVID-19 pandemic on food and nutrition security of households, mothers, and children. We use both pre-pandemic in-person household survey data and a post-pandemic phone survey. Two thirds of our respondents reported that their incomes had fallen after the pandemic began and almost half reported that their ability to satisfy their food needs had worsened. Employing a household fixed effects difference-in-difference approach, we find that the household food insecurity increased by 11.7 percentage points and the size of the food gap by 0.47 months in the aftermath of the onset of the pandemic. Participation in the PSNP offsets virtually all of this adverse change; the likelihood of becoming food insecure increased by only 2.4 percentage points for PSNP households and the duration of the food gap increased by only 0.13 months. The protective role of PSNP is greater for poorer households and those living in remote areas. Results are robust to definitions of PSNP participation, different estimators and how we account for the non-randomness of mobile phone ownership. PSNP households were less likely to reduce expenditures on health and education by 7.7 percentage points and were less likely to reduce expenditures on agricultural inputs by 13 percentage points. By contrast, mothers’ and children’s diets changed little, despite some changes in the composition of diets with consumption of animal source foods declining significantly.
Book Synopsis On the Short Waves, 1923-1945 by : Jerome S. Berg
Download or read book On the Short Waves, 1923-1945 written by Jerome S. Berg and published by McFarland. This book was released on 2007-03-28 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: As radio developed in the early 1920s, the focus for most people was the AM band and stations such as KDKA, the first broadcast station. There was, however, another broadcast method that was popular among many early enthusiasts--shortwave radio. As is true today, the transmission of news and entertainment programs over shortwave frequencies permitted reception over great distances. For many in America and beyond, shortwave was an exciting aspect of the new medium. Some still tune the shortwave bands to enjoy the programming. Others pursue broadcasts for the thrill of the hunt. This book fully covers shortwave broadcasting from its beginning through World War II. A technical history examining the medium's development and use tells the story of a listener community that spanned the globe. Included are overviews of the primary shortwave stations operating worldwide in the 1930s, along with clubs and competitions, publications and prizes. A rich collection of illustrations includes many QSLs, the cards that stations sent to acknowledge receipt of their transmissions and that are much prized by long-distance collectors.

Book Synopsis Mobile Phone Panel Surveys in Developing Countries by : Andrew Dabalen
Download or read book Mobile Phone Panel Surveys in Developing Countries written by Andrew Dabalen and published by World Bank Publications. This book was released on 2016-07-12 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Household survey data are very useful for monitoring living conditions of citizens of any country. In developing countries, a lot of this data are collected through “traditional†? face-to-face household surveys. Due to the remote and dispersed nature of many populations in developing countries, but also because of the complex nature of many survey questionnaires, collection of timely welfare data has often proved expensive and logistically challenging. Yet, there is a need for faster, cheaper to collect, lighter, more nimble data collection methods to address data gaps between big household surveys. The recent proliferation of mobile phone networks has opened new possibilities. By combining baseline data from a traditional household survey with subsequent interviews of selected respondents using mobile phones, this facilitates welfare monitoring and opinion polling almost real time. The purpose of this handbook is to contribute to the development of the new field of mobile phone data collection in developing countries. The handbook documents how this innovative approach to data collection works, its advantages and challenges. The handbook draws primarily from the authors’ first-hand experiences with mobile phone surveys in Africa and also benefits from experiences elsewhere. It is intended to serve a diverse audience including those involved in collecting (representative) data using mobile phones, and those using data collected through this approach. For those who will be implementing a mobile phone panel survey, the different chapters guide them through every stage of the implementation process. For potential users of the data collected via mobile phone technology, the handbook presents a new approach to data collection which they can use for monitoring programs and facilitate almost real time decision-making. A further purpose of this book is to contribute to the debate regarding the advantages of the method as well as the challenges associated with it.
Book Synopsis Household food consumption patterns in Addis Ababa, Ethiopia by : Wolle, Abdulazize
Download or read book Household food consumption patterns in Addis Ababa, Ethiopia written by Wolle, Abdulazize and published by Intl Food Policy Res Inst. This book was released on 2020-03-16 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overweight and obesity are rising rapidly in Ethiopia's urban areas, constituting a major public health concern. Dietary choices can be one of the key drivers of adult body-weight. Using data collected from a large household survey in Addis Ababa, we provide a snapshot of dietary patterns in Ethiopia's largest urban area. We find that starchy staples (cereals, roots, and tubers) are prominent in household food baskets, taking up 25 percent of the food budget and providing more than 50 percent of consumed calories, on average. In contrast, the consumption of all kinds of fruits and vitamin A-rich vegetables is very low. For the average household, meat products account for nearly 18 percent of the food budget but provide only 2 percent of total calories. Richer households consume relatively less starchy staples than poorer households, but more animal-source foods and vegetables. However, the importance of fruits in household diets rises very slowly with household incomes. Together, these findings suggest that further income growth will result in drastic changes in the composition of food demand in Addis Ababa. Considering projections for increasing incomes, especially in urban areas, this will have major implications for agricultural production in rural areas connected to Ethiopia’s cities. There is also an urgent need to design cost-effective public health campaigns to reduce the emerging overweight and obesity crisis in urban Ethiopia.

Book Synopsis How Important is Selection? by : David J. McKenzie
Download or read book How Important is Selection? written by David J. McKenzie and published by World Bank Publications. This book was released on 2006 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Measuring the gain in income from migration is complicated by non-random selection of migrants from the general population, making it difficult to obtain an appropriate comparison group of non-migrants. This paper uses a migrant lottery to overcome this problem, providing an experimental measure of the income gains from migration. New Zealand allows a quota of Tongans to immigrate each year with a lottery to choose among the excess number of applicants. A unique survey conducted by the authors in these two countries allows experimental estimates of the income gains from migration by comparing the incomes of migrants to those who applied to migrate, but whose names were not drawn in the lottery, after allowing for the effect of non-compliance among some of those whose names were drawn. The authors also conducted a survey of individuals who did not apply for the lottery. Comparing this non-applicant group with the migrants enables assessment of the degree to which non-experimental methods can provide an unbiased estimate of the income gains from migration. They find evidence of migrants being positively selected in terms of both observed and unobserved skills. As a result, non-experimental methods are found to overstate the gains from migration, by 9 to 82 percent. A good instrumental variable works best, while difference-in-differences and bias-adjusted propensity-score matching also perform comparatively well."--World Bank web site.
Book Synopsis Poverty Comparisons by : M. Ravallion
Download or read book Poverty Comparisons written by M. Ravallion and published by Taylor & Francis. This book was released on 2013-10-08 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poverty comparisons - such as whether poverty has increased, or where it is greatest, are typically clouded in conceptual and methodological uncertainties. How should individual well-being be assessed in deciding who is poor? Is a household survey a reliable guide? Where should the poverty line be drawn, and does the choice matter? This monograph surveys the issues that need to be considered in answering these questions, providing an accessible introduction to the most recent literature. The strengths and weaknesses of past methods are discussed, and a summary of methodological recommendations is given. A number of new analytical tools are described which can greatly facilitate poverty comparisons, recognising the uncertainties involved.
