Comparative advantage motivates large trade flows in feeder animals throughout the world. Trade creates externalities when animal diseases can spread beyond the purchasing farm. When growers can choose between open and closed production systems, Nash equilibrium will likely involve socially...

A calibrated model is used to determine the welfare impacts of various regulatory instruments for improving health. The results of a lab experiment are integrated in a partial equilibrium model representing demands for two kinds of fish, one with higher nutritional benefits (canned sardines) and...

Many deficiencies in the capacity of a food system to deliver safe products are systemic in nature. We suggest a taxonomy of four general ways in which a systemic failure might occur. One relates to the connectedness, or topology, of the system. Another arises from mistrust on the part of...
