Economic Impact of Public Pest Information: Soybean Insect Forecasts in Illinois
研究在已有商业害虫信息服务的地区引入公共害虫信息（如大豆昆虫预测）的经济影响，发现农民虽能受益，但农药使用变化取决于公共预测的可靠性。
Abstract Previous agricultural pest management information studies have focused on the consequences of providing pest information to farmers without access to other sources of pest information. In view of the proliferation of commercial scouting services, this paper uses a preposterior decision model of pest management to examine the outcomes likely to follow from introduction of public pest information into an area with an existing commercial pest information market. Empirical estimates of the impact of a soybean insect forecast system in Illinois demonstrate that although farmers can benefit from public pest information, the implications for pesticide use depend on the reliability of public forecasts.
