| We propose and develop a new framework for studying the problem of preventing biological invasions caused by ships transporting internationally traded goods between countries and continents. In particular, we apply the methods of queuing theory to analyze the problem of preventing a biological invasion from a long run perspective. First, we characterize two simple regulatory regimes as two different kinds of queues. Second, we show how to pose a publically owned port manager's decision problem as an optimization problem using queuing theoretic techniques. Third, we compare and contrast the optimality conditions emanating from our analysis of the M/M/I/U and the M/M/I/I inspection regimes. We conclude by discussing possible extensions to our basic models. |

| In this article we focus on the effects of preferential trade arrangements on agricultural trade and agricultural income. Given the large number of preferential trade arrangements and complex interactions among them, we attempt to find out whether preferential trade arrangements are beneficial to agricultural trade and income, and are an effective tool to liberalize agricultural trade. The findings suggest that preferential trade arrangements with some exceptions tend to expand agricultural trade and improve agricultural income. |

| This paper shows that free trade reduces the welfare of a small country with unemployment unless the free trade price if the importable falls below the autarky equivalent price. A decline in the price of the importable from the autarky level not only improves the terms of trade but also reduces employment and production in the importable sector. A numerical example illustrates that the autarky equivalent price of the importable can be substantially lower than the autarky price. If an optimal tariff is used, however, restricted trade improves welfare above the autarky level. |
