摘要：This analysis presents a theoretical model of firm response to border enforcement and evaluates both the intended and unintended effects under two enforcement regimes: destruction versus treatment of contaminated shipments. The results indicate that importers may respond to increased inspection by reducing shipments and decreasing due care. In response to increased pest populations, firms may reduce shipments and increase due care, indicating that an enforcement response may not be necessary. The analysis reveals the importance of the nature of the due-care technology, as well as the relationships underlying the probability of detection, in determining the effects of enforcement.
