Infectious Animal Disease and Animal Health Economics
For those interested in the history and economics of animal disease prevention and control, there can be no better book to read than:
Arresting Contagion: Science, Policy, and Conflicts over Animal Disease Control (2015) by A.L. Olmstead and P.W. Rhode.
Infectious Animal Disease and Animal Health Economics is a large and very active area of research. Several others in AFRE are also active in the area. The issues that coauthors and I have addressed have received less attention in the area. One theme is the relationships between infectious disease, the feeder animal trade and scale economies.

Other papers have considered the distinction between efforts to prevent a disease and to cure that disease, both when infection externalities are not present, and when they are present.

Among the points being made in the papers are that bio-security actions to protect resources typically need to be viewed in their totality, including public actions and the dispersed set of private actions; that interactions among these bio-security actions can differ greatly according to their purpose; and that failure to recognize these differences can undermine public and private sector endeavors to protect resources.
Information is another theme in some of the works, where it seems reasonable to assume that private businesses have more information about their disease status than do public animal health control agencies.

A separate theme has been interactions between structural change in the animal protein production and animal health inputs, including bio-security inputs and antibiotics.

A related theme has been the U.S. market for veterinarian services to large animals. This market has had to adapt to deep structural change in the animal protein sector, leading to changes in the nature of demand for services and how they are delivered.
