本文探讨了如何最佳的预防和控制政策取决于经济和生物特性的随机引入的生物入侵的目标是最大限度地减少预期的社会成本从预防，控制和入侵损害。结果表明，最优的预防和控制策略如何随初始入侵规模、入侵增长率和入侵的概率分布而变化。本文还研究了条件下，最佳的政策完全依赖于预防或控制，条件下，它是最佳的，以完全防止新的引进，以及条件下，建立入侵的根除是最佳的。
This paper examines how optimal prevention and control policies depend on the economic and biological characteristics of a randomly introduced biological invasion where the objective is to minimize the expected social costs from prevention, control, and invasion damages. The results characterize how optimal prevention and control policies vary with the initial invasion size, the invasion growth rate, and the probability distribution of introductions. The paper also examines the conditions under which the optimal policy relies solely on either prevention or control, the conditions under which it is optimal to completely prevent new introductions, and the conditions under which eradication of established invasions is optimal.
