Abstract

Researchers commonly use linked data as an empirical tool because information relevant to answer policy questions is often dispersed across multiple sources. To understand how linked data are used in food and agricultural economics research, we conducted a systematic review of 104 peer-reviewed articles, published between 2000 and 2020, in which authors combine data sources to conduct their intended analyses. With our sample of papers, we classify types of data used, describe linkage methods, and summarize empirical approaches. Results show that most studies use public data, and many apply causal methods to examine food policy questions. These patterns highlight the value of public data and the role of linked datasets in food and agricultural economics research. Continued investment in data access, infrastructure, and shared practices for managing and analyzing integrated datasets can strengthen and expand the use of linked data in future research.
