  • Book cover of Telescoping causes overstatement in recalled food consumption: Evidence from a survey experiment in Ethiopia

    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.

  • Book cover of Agricultural intensification in Ethiopia: Patterns, trends, and welfare impacts

    This study examined the patterns, trends, and drivers of agricultural intensification and productivity growth during the recent decade (2012 - 2019) using three rounds of household data collected from four agricultural regions of Ethiopia. The descriptive results indicate a positive trend both in adoption and intensity of inputs and outputs, albeit from a low base and with considerable heterogeneity by access to information, rainfall levels and variability, labor, soil quality, and remoteness, among others. The econometric results show significant association between intensification, yield growth, household dietary diversity, and consumer durables. The results on the association between current yield levels and per capita consumption expenditures are however mixed (i.e., while an increase in cereal yield improves food consumption expenditures, an increase in cash crop yield improves only non-food consumption expenditures). In sum, while the increasing input intensification and the resulting yield gains are associated with improvements in household diets and consumer durables, it falls short to have strong impact on incomes (as measured by total consumption expenditures), indicating that additional efforts must be made to see meaningful impacts on higher order outcomes. Additional welfare improving productivity gains through increased input intensification may require investments in appropriate fertilizer blends; investments in improved seeds (to accelerate varietal turnover), ways to mitigate production (rainfall) risk, and investments to remodel Ethiopia’s extension system to provide much needed technical support to farmers on production methods.

  • Book cover of Household food consumption patterns in Addis Ababa, Ethiopia

    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 cover of Evaluation of the nutrition-sensitive features of the fourth phase of Ethiopia's Productive Safety Net Programme

    This study assesses progress in the implementation of the nutrition-sensitive interventions of the fourth phase of Ethiopia’s Productive Safety Net Programme (PSNP-4) and its impact on: (1) the pathways underpinning children’s nutritional status; and (2) the roles it plays in reducing the malign effect of seasonality on the nutritional status of women and pre-school children. The analysis is based on four rounds of household survey data, conducted in March and August 2017 (baseline) and March and August 2019 (endline). These surveys focused on households with a child less than 24 months of age (index child) and his/her mother (index mother). In 2017 and 2019, the survey teams visited more than 2,500 households in 264 kebeles in 88 PSNP woredas in the Amhara, Oromia, SNNP, and Tigray regions.
