Using Scanner Data for Food Policy Research is a practitioners' guide to using and interpreting scanner data obtained from stores and households in policy research. It provides practical advice for using the data and interpreting their results. It helps the reader address key methodological issues such as aggregation, constructing price indices, and matching the data to nutrient values. It demonstrates some of the key econometric and statistical applications of the data, including estimating demand systems for policy simulation, analyzing effects of food access on food choices, and conducting cost-benefit analysis of food policies.
This guide is intended for early-career researchers, particularly those working with scanner data in agricultural and food economics, nutrition, and public health contexts.
- Describe different types of scanner data, the types of information available in the data, and the vendors that offer these data
- Describe food-label data that can be appended to scanner data
- Identify key questions that researchers should consider when acquiring scanner and label data for food policy research
- Demonstrate how to use scanner data using tools from econometric and statistical analyses, including the limitations in interpreting results using the data
- Describe and resolve key methodological issues related to using the data to facilitate more rapid analyses
- Provide an overview of published literature as background for designing new studies
- Demonstrate key applications of the data for food policy research
Mary K. Muth, PhD, is director of RTI International's Food, Nutrition, and Obesity Policy Research Program. Muth conducts research studies for government agencies and other organizations to analyse the impacts of policies, regulations, and other initiatives affecting food and agriculture. She specializes in the areas of nutrition, food security, food waste, food pricing, food labelling, food reformulation, and food safety. She has extensive experience analysing food availability, purchase, and consumption data and developing economic models of the impacts of food policy. Dr. Muth is also an adjunct associate professor in the Department of Agricultural and Resource Economics at North Carolina State University.
