Welcome to my website! My research has focused on three areas. The first is agricultural policy analysis, where I examine how the US federal crop insurance program affects various aspects of agricultural production, including land use, water use, crop yields, and agricultural innovation. The second area is to study the interaction between agricultural production and the environment, such as the responsiveness of crop yields to weather variation and how pesticide use affects bird biodiversity in the US. Last but not least, I am interested in examining the role of ambiguity preferences in people’s decision making. A current application of the analysis is to understand the relationship between date labels on food items and consumers’ food waste behavior.
