| This article examines a tradeoff between ex ante mitigation costs and ex post costs of response to a potential introduction of animal disease such as Foot and Mouth (FMD). In a simplified case study setting we examine the conditions for optimality of enhanced detection systems considering various characteristics of a potential FMD outbreak, costs of program implementation, severity of the disease outbreak, and relative effectiveness of surveillance and response strategies. We show that the decision to invest in ex ante detection activities depends on such factors as likelihood of disease introduction, disease spread rate, relative costs, ancillary benefits and effectiveness of mitigation strategies. While for slow spreading disease the investment in... |

| In this paper, we examine conditional, forecast-based dynamic pest management in agricultural crop production given stochastic pest infestations and stochastic climate dynamics throughout the growing season. Using stochastic optimal control we show that correlation between forecast error for climate prediction and forecast error for pest outbreaks can be used to improve pesticide application efficiency. In the general setting, we apply modified Hamiltonian approach to discuss the steady state equilibrium. Given specific functional forms, a closed form solution can be found for the stochastic optimal control problem. Moreover, we find conditions for model parameters so that the optimal pesticide usage path will be monotonically increasing or decreasing in... |

| This study presents a conceptual model for the analysis of avian influenza mitigation options within the small poultry farm sector (backyard flocks). The proposed model incorporates epidemiological susceptible-infected-recovered (SIR) methodology into an economic cost-minimization framework. The model is used to investigate the implications and interdependencies of mitigation options that influence inter-flock contact rates of asymptomatic and symptomatic flocks, and reduce the duration of symptomatic and asymptomatic periods. The results indicates that for shorter asymptomatic periods the efforts to control inter-flock contract rates should concentrate on symptomatic flocks, while for longer asymptomatic periods the control of inter-flock contacts should... |

| One of the options to prepare for a potential outbreak of an infectious livestock disease is to initiate an animal tracking system, which would provide information on animal movements and facilitate disease management. This study examines the benefits of implementing an animal tracking system in the context of a simulated cattle disease outbreak with and without animal tracking. Estimates are provided for some of the losses that would be avoided with an animal tracking system if an infectious animal disease were introduced. The results show that the economic efficiency of an animal tracking system depends on such factors as inter-herd contact rates, effectiveness of animal disease response actions, and the extent to which an animal tracking system... |

| Outbreaks of infectious animal diseases can lead to substantial losses as evidenced by 2003 US BSE (Bovine Spongiform Encephalopathy) event with consequent loss of export markets, and the 2001 UK FMD (Foot and Mouth Disease) outbreak that has cost estimates in the billions. In this paper we present a linked epidemiologic-economic modeling framework which is used to investigate several FMD mitigation strategies under the context of an FMD outbreak in a concentrated cattle feeding region in the US. In this study we extend the literature by investigating the economic effectiveness of some previously unaddressed strategies including early detection, enhanced vaccine availability, and enhanced surveillance under various combinations of slaughter,... |

| This study examines the effects of climatic conditions on interactions among pea and lentil yields, pea aphid Acyrthosiphon pisum (Harris) infestations, and outbreaks of PEMV (Pea enation mosaic) and BLRV (Bean leaf roll) viruses in the Palouse region of easternWashington. The study analytically and empirically evaluates the effects of aphid outbreaks on per acre yields, implicitly including the effects of adopted pest management activities and explicitly taking into account possible effects of climatic conditions on the severity of pea aphid outbreaks. The results show that aphid outbreaks have historically decreased pea and lentil yields by approximately 5% and 7% on average respectively. |
