Using household consumption and expenditure surveys to make inferences about food consumption, nutrient intakes and nutrition status


Book Description

Household consumption and expenditure surveys (HCES) are multipurpose surveys that are routinely conducted to collect data on household food consumption and availability in more than 120 countries. HCES are increasingly being used to calculate proxy estimates of food consumption, nutrient intakes, and nutrition status, often at the individual level. Rarely, however, do they collect information on meal participation, despite growing evidence that it is an increasingly important and variable component of the quantity of food consumed or available in a household. This paper explores the significance of adjusting for meal participation in making inferences about apparent food consumption and nutrient intakes. It focuses on two distinct sets of additional information requirements for enhancing the reliability and precision of measures of food consumption: (1) individual household members’ and household guests’ meal-eating behaviors, and (2) the number and apparent nutritional significance of meals. While the most comprehensive and precise accounting of intakes of individual food consumption and nutrients requires both types of information, the magnitude of the changes required in HCES questionnaires to capture them is likely to be prohibitive. Consequently, for many HCES, a “second best” approach may be the most effective method, at least in the short term. The paper empirically explores some of the relatively few HCES that currently attempt to capture some of these information requirements. In addition, it assesses their value-added to prioritize the global agenda for strengthening HCES measurement of food consumption in support of more evidence-based nutrition policy making.




Entitlement fetching or snatching? Effects of arbitrage on India’s public distribution system


Book Description

Would households be able to buy more subsidized grains from a food-based safety-net program if the difference between prices in the program and in the open market were to increase? This is an important question for safety-net programs anywhere in the world, but particularly so for the public distribution system (PDS) of grains in India—the largest food-based safety-net program in the world. The standard economic intuition suggests that price controls distort signals and create incentives for unintended transactions. Price difference between the PDS and the open market compromise entitlements and divert grains to open markets—an entitlement-snatching effect. Drèze and Sen (2013), however, posit the opposite—an entitlement-fetching effect, where an increase in arbitrage increases the value of PDS entitlement. This raises the stakes in the PDS for eligible beneficiaries, resulting in a rise in accountability and ultimately an increase in household purchases of grains from the PDS. We test these two competing hypotheses using multiple datasets: consumer expenditure surveys conducted by the National Sample Survey Organization, and panel datasets from the India Human Development Survey and the Village Dynamics in South Asia. Depending on the context, we find both entitlement-snatching and entitlement-fetching effects. In states where welfare programs are better governed, the Drèze and Sen (2013) conjecture holds. Conversely, in states like Bihar and Jharkhand—where welfare programs are poorly run—the opposite pattern holds; that is, households’ purchase of subsidized grains recedes with greater arbitrage.




Changing preferences through experimental games


Book Description

Much policy interest in sanitation and hygiene promotion focuses on changing behavior and increasing demand for these goods. Yet the effectiveness of large-scale interventions has been mixed, in large part because of the difficulty of changing attitudes on deeply rooted behaviors. This study tests whether an experiential learning exercise structured around an experimental game can be used to shift preferences around sanitation and hygiene. A minimum coordination game is adapted to the sanitation and hygiene setting by linking game choices to real-world investment decisions and payoffs in terms of health and status. Individuals from 20 villages in rural Tamil Nadu were randomly assigned to one of three groups: one that played a game in which communication between rounds was allowed, another that played a game in which communication was prohibited, and a control group that only completed a survey. Based on a comparison of survey responses across treatment arms, the game improved stated preferences in relation to sanitation and hygiene. This effect was larger when communication was allowed, and men responded on average more strongly than women across both versions of the game. These results suggest that experimental games can be a valuable tool not only for the study of decision making but for improving participants’ knowledge and pro-sanitation preferences.




Nepal’s 2072 federal constitution: Implications for the governance of the agricultural sector


Book Description

In this paper we explore the implications of Nepal’s new federal Constitution—passed in September 2015—for governance of the agricultural sector. Agriculture is the backbone of the Nepali economy, providing a livelihood for approximately two-thirds of the population, contributing one-third of the country’s GDP, and constituting more than half of the country’s exports. In transitioning from a unitary to a federal republic—with greater authority and autonomy granted to subnational units of government—it is of paramount importance to ensure that the agricultural sector is guided by coordinated planning, retains sufficient human capacity, and receives adequate fiscal resources. These considerations are particularly important given that the governance of Nepal’s agricultural sector already suffers from poor coordination, low human resources capacity, and inadequate financial resources. Addressing these issues may become more difficult under a federal structure. This paper begins by laying out the main challenges for agricultural governance in Nepal under the current structure. To do so, it relies on an original survey of 100 district agricultural and livestock officers in charge of local agricultural service delivery in Nepal as well as perspectives collected through more than two dozen semi-structured interviews with officials from the Ministry of Agricultural Development, the Ministry of Livestock Development, civil society, the private sector, and donors. Because Nepal is embarking on a pathway to more decentralized governance, which has been well-trodden by a number of other countries, the paper proceeds by examining five case studies, drawing lessons from India, Indonesia, Kenya, Malaysia, and South Africa. Based on these analyses, the paper offers policy recommendations on how the sector can be restructured to meet the constitutional provisions, while simultaneously ensuring that the government can deliver on its long-term objectives to develop the agricultural sector.




Building effective clusters and industrial parks


Book Description

It is a daunting task to build institution and infrastructure over a short time period in developing countries. But in the absence of sound institutions and adequate infrastructure, it is difficult for economic transformation to take place. An alternative is to facilitate existing industrial clusters or build industrial parks by creating an enabling environment in a limited place. This paper reviews the commonly used strategies to build effective clusters and industrial parks. Clusters and industrial parks are location specific. Because they have an informational advantage, local governments are in a better position than the central government to identify and solve the bottlenecks that affect clusters and industrial parks. As clusters and industrial parks evolve, new bottlenecks emerge, thereby requiring new solutions. This in turns calls for continuous tinkering by local governments. It is important to place local governments and business communities in the driver’s seat of local economic growth so that they can watch out for and adjust to the bumps in the road ahead.




Improving household consumption and expenditure surveys’ food consumption metrics


Book Description

As the nature of global malnutrition changes, there is a growing need and increasing urgency for more and better information about food consumption and dietary patterns. The past two decades have seen a dramatic increase in the number, availability, and analysis of the food consumption data collected in a variety of multipurpose household surveys, referred to collectively as household consumption and expenditure surveys (HCESs). These surveys are heterogeneous, and their quality varies substantially by country. Still, they share some common shortcomings in their measurement of food consumption, nutrient intakes, and nutrition status that undermine their relevance and reliability for purposes of designing and implementing food policies and programs. This review crafts a strategic approach to the unfinished global agenda of improving HCESs’ collection of food consumption data. Starting with the priority studies recommended by a 100-country HCES review (Smith, Dupriez, and Troubat 2014), it focuses on a strategic subset of those studies that deal most directly and exclusively with the measurement of food, and that are of fundamental importance to all HCES stakeholders in low- and middle-income countries. Drawing from the literature, this study provides a more detailed, more circumspect justification as to why these particular studies are needed, while identifying key hypotheses, explaining why these studies are of growing urgency, and demonstrating why now is a propitious time for undertaking them. The review also identifies important study design considerations while pointing out potential challenges to successful implementation stemming from technical capacity, economic, administrative, and political considerations. Six key studies are rank ordered from a global perspective as follows, taking into account (1) the likely shared consensus that a topic is an important source of measurement error in estimating consumption; (2) the perceived urgency of the need for addressing a particular source of measurement error; (3) the perceived likelihood of success—that is, that the efforts will improve the accuracy of measurement; (4) whether or not the study entails modifying the questionnaire; (5) the ease with which a study may begin; and (6) the extent to which the study is independent of necessary negotiations with existing HCES stakeholders because of the types of changes it is likely to entail (in either the questionnaire or the way the data have traditionally been processed).




The role of learning in technology adoption: Evidence on hybrid rice adoption in Bihar, India


Book Description

Much empirical research has shown that individuals’ decisions to adopt a new technology are the result of learning–both through personal experimentation through observing the experimentation of others. Yet even casual observation would suggest significant heterogeneity of learning processes, manifesting itself in widely varying patterns of adoption over space and time. This paper explores this heterogeneity in the context of early adoption of hybrid rice in rural India. Using specially designed experiments conducted as part of a primary survey in the field, we identify which of four broad learning heuristics most accurately reflects individuals’ information processing strategies. Linking these learning heuristics with observed use of rice hybrids, we demonstrate that pure Bayesian learning is well suited for the tinkering and marginal adjustments that are required to learn about a technology like hybrid rice, but it is also more cognitively taxing than other learning styles requiring a longer memory and more complex updating processes. Consequently, only about 25 percent of the farmers in our sample can be characterized as pure Bayesian learners. Present-biased learning and relying on first impressions will likely hinder adoption of a technology like hybrid rice, even after controlling for access to credit and a rudimentary proxy for intelligence.




External shocks, food security, and development


Book Description

We conduct an ex ante evaluation of the impacts of a potential global recession within the next years and the possible policy responses to support economic activity and improve social indicators in five Central American countries: Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. We review the economic and social evolution of the past decades in those countries, and we consider a global scenario that includes further deceleration of world growth, lower commodity prices, and a decline in remittances and capital flows to those countries. We simulate those scenarios and related policy issues using recursive dynamic CGE models for the countries considered. The global shock is run under fixed exchange rates and flexible exchange rates (in the case of El Salvador, which has adopted the US dollar as the domestic currency, the simulation of a flexible exchange rate is just indicative). In all cases, a flexible exchange rate delivers better results in terms of GDP per capita, by softening the overall economic impact of the external shocks. Two possible interventions to deal with the recession are simulated: one focuses on policies to strengthen the safety net for the poor; the other applies a more general macroeconomic stimulus (a tax cut plus a modest increase in public investments, financed by un-conventional monetary policy) to try to cushion the shock. For all countries except El Salvador, these two simulations are run with a flexible exchange rate. In the first policy simulation GDP per capita in those countries does not change much, but the poor groups targeted clearly improve their incomes and consumption, helping them the most during the years of the negative shocks. In the second simulation, the macroeconomic stimulus improves the performance of the economies, allowing GDP per capita to be higher than in the case of the shock alone. In summary, facing a potential global downturn as the one simulated here, those countries that have flexible exchange rates and the use of domestic monetary policies can use a mix of adjustment in exchange rates combined with targeted poverty transfers and macroeconomic stimulus to alleviate the shock. El Salvador, which does not have the exchange rate and monetary instruments, will require further support from multilateral and bilateral sources to soften the shock




Harnessing net primary productivity data for monitoring sustainable development of agriculture


Book Description

This study was undertaken to assess the utility of remotely sensed net primary productivity (NPP) data to measure agricultural sustainability by applying a new methodology that captures spatial variability and trends in total NPP and in NPP removed at harvest. The sustainable intensification of agriculture is widely promoted as a means for achieving the Sustainable Development Goals (SDGs) and transitioning toward a more productive, sustainable, and inclusive agriculture, particularity in fragile environments. Yet critics claim that the 17 SDGs and 169 targets are immeasurable and unmanageable. We propose adoption of satellite-estimated, time-series NPP data to monitor agricultural intensification and sustainability, as it is one indicator potentially valuable across several SDGs. To illustrate, we present a unique monitoring framework and a novel indicator, the agricultural appropriation of net primary productivity (AANPP) and analyze spatial trends in NPP and AANPP across the continent of Africa. AANPP focuses on the proportion of total crop NPP removed at harvest. We estimate AANPP by overlaying remotely sensed satellite imagery with rasterized crop production data at 10-by-10-kilometer spatial resolution; we explore variation in NPP and AANPP in terms of food and ecological security. The spatial distribution of NPP and AANPP illustrates the dominance of cropping systems as spatial drivers of NPP across many regions in West and East Africa, as well as in the fertile river valleys across North Africa and the Sahel, where access to irrigation and other technological inputs are inflating AANPP relative to NPP. A comparison of 2000 and 2005 datasets showed increasing AANPP in African countries south of the Sahara—particularly in Mozambique, Angola, and Zambia—whereas NPP either held stable or decreased considerably. This pattern was especially evident subnationally in Ethiopia. Such trends highlight increasing vulnerability of populations to food and ecological insecurity. When combined with other indicators and time-series data, the significance of NPP and the capacity of spatially explicit datasets have far-reaching implications for monitoring the progress of sustainable development in a post-2015 world.




Identity, household work, and subjective well-being among rural women in Bangladesh


Book Description

Despite increases in women’s employment, significant gender disparity exists in the time men and women spend on household and care work. Understanding how social expectations govern gender roles and contribute to this disparity is essential for designing policies that effectively promote a more equitable household division of labor. In this study, we examine how a woman’s identity may affect the trade-offs between the time she spends on household and care work and her well-being, using an analytical framework we develop based on the work of Akerlof and Kranton. Analyzing data from rural Bangladesh, we find that longer hours spent on household work are associated with lower levels of subjective well-being among women who disagree with patriarchal notions of gender roles, while the opposite is true for women who agree with patriarchal notions of gender roles. Importantly, this pattern holds only when a woman strongly identifies with patriarchal or egalitarian notions of gender role.
