Purpose – Despite the existence of hundreds of studies and several review articles on consumer preferences for genetically modified (GM) food, it remains difficult to ascertain the current state of knowledge on the topic. The purpose of this chapter is to distill some of the key findings from the body of research on consumer preferences for GM food.
Approach – In reviewing key pieces of literature, including two meta-analyses, the chapter identifies four key unresolved questions and includes discussions on how the questions might be resolved.
Findings – The chapter identifies four questions in need of additional thought and research. The questions relate to (1) why the market for GM-free food is so small in the United States despite the large estimated willingness-to-pay premiums for GM-free food, (2) why consumers remain so uninformed about biotechnology despite their seemingly high levels of aversion, (3) why economists have generally ignored the information-content of GM food policies, and (4) why it is so difficult to determine why U.S. and European consumers have seemingly reacted so differently to GM foods.
Value – This chapter should be useful to those interested in learning about the current state of knowledge on consumer preferences for GM food, and to those seeking to identify areas in need of additional research.
