摘要：This article presents a dynamic bioeconomic model of livestock disease control thatis unique in its integration of disease dynamics, inter-species interaction, control-induced migration, and individual optimising behaviour. Examination of the ￠rst-order conditions highlights why pro￠t-maximising producers cannot be expected toeradicate disease. Results from an empirical application of the model con￠rm thatthe current mix of policies to control bovine tuberculosis in New Zealand isachieving lower levels of prevalence than would prevail in the absence of a nationalstrategy. These policies do, however, appear to remove some of the individualincentive to control disease.
