In this paper, we conduct a theoretical analysis of inspections in a stochastic environment and we shed light on two hitherto unstudied issues concerning inspections in the context of invasive species management. First, given a particular port of entry in a country, we study the properties of a...

This paper reviews recent work examining two topics of economic research vital for invasive species policy-integration and valuation. Integration requires bioeconomic models that blend invasive biology with economic circumstances and the feedback loops between the two systems. Valuation requires...

This paper develops a two-stage model for the optimal management of a potential invasive species. The arrival of an invasive species is modeled as an irreversible event with an uncertain arrival time. The model is solved in two stages, beginning with the post-invasion stage. In this stage, we...

In this paper, an integrated model for the prevention and control of an invasive species is developed. The generality of the model allows it to be used for both existing and potential threats to the system of interest. The deterministic nature of arrivals in the model allows for a clear...

We analyze the linkage between protectionism and invasive species (IS) hazard in the context of two-way trade and multilateral trade integration, two major features of real-world agricultural trade. Multilateral integration includes the joint reduction of tariffs and trade costs among trading...

We investigate the interface between trade and invasive species (IS) risk, focusing on the existing tariff escalation in agro-forestry product markets and its implication for IS risk. Tariff escalation in processed agro-forestry products exacerbates the risk of IS by biasing trade flows toward...

Introductions of nonindigenous organisms into the United States have been linked to international trade. The individual contributions of imports, immigration, and international travel, however, are poorly understood because introduction dates are unavailable. We examine relationships between...

Dominant users of Lake Okeechobee water resources are agricultural producers and recreational anglers. These uses will be directly affected, should the lake become infested with zebra mussels. We employ a probabilistic bioeconomic simulation model to estimate the potential impact of zebra...
