We first construct three measures of the expected damage from the unintentional introduction of alien species into a country called Home. We then focus on four market structures. First, perfect competition prevails in both Home and Foreign and Home is a small country. Second, the Home and the...

In order to minimize the risk of biological invasions in a country called Home, a seaport manager must inspect a certain number of arriving ships successfully in a time period of interest. Given that inspections are costly, how should our seaport manager, interested in minimizing the total...

The many aspects of alien species management normally all involve decision making over time and under uncertainty. Therefore, in this note, we focus on an arbitrary seaport in a country called Home and we conduct a dynamic and stochastic analysis of two questions that have received insufficient...

The risk of unintentional biological invasions in a nation typically varies by trading partner. Because this recognition has been very recent, several theoretical issues concerning the differential treatment of trading partners in alien species management remain inadequately studied. Therefore,...

The extant literature has delineated some of the ways in which uncertainty affects the management of alien species. In this paper, we continue this line of inquiry and shed light on two insufficiently studied issues concerning the probabilistic nature of biological invasions. First, we determine...

The maritime trade related risks from invasive species in a nation depend, inter alia, on the countries from which goods are being imported. In the United States, the USDA's APHIS routinely uses inspections to screen arriving ships at seaports for invasive species. Given this state of affairs,...
