While the impacts can be measured with precision only ex post, for policy makers it is critical to get a sense of likely impacts ex ante in order to plan approaches to mitigate these impacts. In this paper we adopt a very simple micro-based simulation approach to analyze how changes in prices of specific food groups, such as maize prices or prices for staple foods, as well as how negative short-term household level income shocks affect the entitlements to calorie consumption of individuals and how these changes affect overall food poverty. We illustrate our approach using household survey data from Malawi. We find that food poverty is of serious concern with large within-country variations. We find that price shocks for staple foods have a considerable impact on food security with particularly strong effects on poor net food buyers in rural and urban areas. This paper demonstrates that it is possible to estimate food security impacts of price and income shocks ex ante in a relatively straightforward fashion that can be done relatively quickly and that is suitable for cross-country assessments of the likely impacts of shocks on food security and the design of appropriate response measures."],["dc.identifier.doi","10.1016/j.foodpol.2015.03.007"],["dc.identifier.fs","621675"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/10580"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0306-9192"],["dc.subject","Food Security; Malawi; Shocks"],["dc.title","Analyzing nutritional impacts of price and income related shocks in Malawi: Simulating household entitlements to food"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","unknown"],["dspace.entity.type","Publication"]]

To establish causality, we selected study sites that differ in their supermarket access, and employ instrumental variable techniques to allow for endogeneity of supermarket purchases. We find that supermarket purchases increase the consumption of processed foods at the expense of unprocessed foods. Supermarket purchases increase per capita calorie availability, which is linked to lower prices paid per calorie, particularly for processed foods. Our results imply that supermarkets contribute to dietary changes commonly associated with the nutrition transition.

This nutrition transition coincides with a rapid expansion of supermarkets. The objective of the present research is to study whether supermarkets directly contribute to overweight and other changes in nutritional status. This research builds on cross-sectional observational data. Household- and individual-level data were collected in Kenya using a quasi-experimental survey design. Instrumental variable regressions were employed to analyse the impact of supermarket purchase on nutritional status. Causal chain models were estimated to examine pathways through which supermarkets affect nutrition. Small towns in Central Province of Kenya with and without supermarkets. A total of 615 adults and 216 children and adolescents. Controlling for other factors, buying in a supermarket is associated with a significantly higher BMI (P=0·018) and a higher probability of overweight (P=0·057) among adults. This effect is not observed for children and adolescents. Instead, buying in a supermarket seems to reduce child undernutrition measured by height-for-age Z-score (P=0·017). Impacts of supermarkets depend on many factors including people’s initial nutritional status. For both adults and children, the nutrition effects occur through higher food energy consumption and changes in dietary composition. Supermarkets and their food sales strategies contribute to changing food consumption habits and nutritional outcomes. Yet the types of outcomes differ by age cohort and initial nutritional status.
