MODELING THE IMPACTS OF ALTERNATIVE INVASIVE SPECIES MANAGEMENT POLICIES ON LIVESTOCK PRODUCTION AgEcon
Zhao, Zishun; Wahl, Thomas I.; Diaz, Ricardo.
In this paper, a dynamic optimization modeling framework for livestock production is developed for the purpose of evaluating the welfare effects of the introduction of invasive species. A beef production model implemented based on the conceptual framework shows that the model is valid and stable. The modeling framework can be used to assess the welfare effects under alternative IS management policies and optimal resource allocation schemes for policymakers.

THE EFFECTS OF EXCHANGE RATE FLUCTUATIONS ON LIVE HOG TRADE BETWEEN THE U.S. AND CANADA AgEcon
Zhao, Zishun; Klein, Nicole L.; Santos, Joseph M..
The real exchange rate is often blamed as a main reason for the increased imports of live hogs from Canada. This study uses co-integration of weekly data from Jan 1997 to Jun 2000 to examine the real exchange rate fluctuations and their effects on live hog trade between the two countries.

Invasive Species Management: Foot-and-Mouth Disease in the U.S. Beef Industry AgEcon
Zhao, Zishun; Wahl, Thomas I.; Marsh, Thomas L..
A conceptual bio-economic framework that integrates dynamic epidemiologicaleconomic processes was designed to analyze the effects of invasive species introduction on decision-making in a livestock sector (e.g., production and feeding). The framework integrates an epidemiological model, a dynamic livestock production model, domestic consumption, and international trade. The integrated approach captures producer and consumer responses to, and welfare outcomes of, livestock disease outbreaks, as well as alternative invasive species management policies. Scenarios of foot-and-mouth disease are simulated to demonstrate the usefulness of the framework in facilitating invasive species policy design.
