This chapter provides a review of the role of field experiments (FEs) in answering research questions in agriculture that ultimately let us better understand how policy can improve productivity and farmer welfare in developing economies. We first review recent FEs in agriculture, highlighting the contributions they have already made to this area of research. We then outline areas where experiments can further fill existing gaps in our knowledge on agriculture and how future experiments can address the specific complexities in agriculture.
