This document discusses the potential for agricultural economists to utilize big data. It outlines three ways economists could be involved: 1) Help industry and government innovate with big data and ICT, 2) Analyze the effects of these innovations on food chain structure and performance, and 3) Conduct policy analysis using big data. Two examples are given of building large datasets: linking existing farm data (FADN) with new sources, and creating a food/nutrition/health research infrastructure combining consumer and sector data. Overall, the document argues big data analysis holds promise for understanding farm decision-making but developing large linked datasets is still nascent.
