Nagurney Co-authors Paper, Op-ed Column

Ladimer S. Nagurney, associate professor of electrical, computer, and biomedical engineering, CETA, has co-authored an article, "Spatial Price Equilibrium and Food Webs: The Economics of Predator-Prey Networks," that appears as the lead article in the Proceedings of the 2011 International Conference on Supernetworks and System Management, published by the IEEE.

The paper proves that the equilibrium of predator-prey networks is, in fact, a spatial price equilibrium. This result demonstrates the underlying economics of predator-prey relationships and interactions and provides a foundation for the formulation and analysis of complex food webs, which are nature's supply chains, through the formalism of network equilibrium. Moreover, it rigorously links the equilibrium conditions of commodity networks in which a product is produced, transported, and consumed, with those of ecological networks in which prey are consumed by predators. The work is co-authored with Professor Anna Nagurney of the Isenberg School of Management at UMass Amherst.

In addition, Ladimer and Anna Nagurney co-authored an op-ed column that was published in the July 10 edition of the Springfield (MA) Sunday Republican. The column is headlined "Viewpoint: Passage of American Medical Isotope Production Act of 2011 will help ensure U.S. nuclear medicine supply chain."
