Farm labor scarcity and its uneven impacts on crop producers in the United States
American Journal of Agricultural Economics, EarlyView.Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Risk management externalities in agrifood supply chains
American Journal of Agricultural Economics, EarlyView.Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Premium subsidy designs and crowding out of insurance demand
American Journal of Agricultural Economics, EarlyView.Abstract Crop insurance is an important instrument to protect farmers against extreme weather events. Many countries provide subsidies for crop insurance products to make insurance more affordable for farmers. The Federal Crop Insurance Program in the United States and major European crop insurance programs such as in Spain, Italy, and France focus on ...

American Journal of Agricultural Economics, EarlyView.Abstract Protecting endangered aquatic species while sustaining farming communities can require water buyback programs that are both cost‐effective and responsive to the variability and unpredictability of drought conditions. Working in close partnership with The Nature Conservancy and the Georgia Water Planning and Policy Center, we co‐design parallel
