The extant literature tells us that a seaport inspector who places a large (small) weight on biological invasion damage control relative to economic cost reduction will, ceteris paribus, inspect ships with containers more (less) stringently. Therefore, in this theoretical note we analyze the...

We study the problem of precluding biological invasions caused by ships transporting internationally traded goods in containers between different regions of the world. Using the long run expected net cost (LRENC) of inspections as the apposite managerial objective, we address the following...

We propose a research agenda for studying six basic questions about the impacts of alternate international invasive species control mechanisms on economic agents in a nation such as the USA. The six questions are as follows. First, when can one justify a trade ban as an effective regulatory...

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...

In recent times - see Batabyal and Nijkamp (2005) and Batabyal and Lee (2006) - there has been considerable interest in studying container inspection policies as a regulatory tool in invasive species management. In this note, we continue this line of inquiry and first delineate a generic...

We begin by outlining some of the more salient issues in contemporary research on the management of invasive species. Next, we note that even though there is a sizeable literature in both biology and economics on invasive species management, until very recently, there has been a significant...

Recently, Batabyal and Nijkamp (2005) have shown that in an inspection cycle, regardless of whether the inspection policy choice is made on the basis of an optimization exercise or on the basis of a rule of thumb, the "container policy" dominates the "temporal policy" because the container...

In this paper we present a continuous time optimal control analysis of resistance buildup in agricultural chemicals when the supplier is a monopolist. We solve a general model and examine the solutions for Cobb-Douglas demand, including a simulation of changes in the interest rate and pest...
