We consider the problem of designing a 2-stations Automated Guided Vehicle System (AGVS). The AGV System consists of a pool of vehicles that transports products from one station to the other station through an unidirectional guidepath.

In this paper we develop a new theory of static equilibrium in congested transportation networks. Our considerations are based on a physical meaning of the flows rather than on an artificially chosen model of travel time functionsl We introduce a concept of the stable equilibrium and prove the...

A key recent theme in maritime freight transport is the involvement of shipping lines in terminal management. Such investments are costly but allow liners to provide better service. Most of these new terminals are dedicated terminals but some are non-exclusive and let rivals access them for a...

Domestic transfers such that all individuals gain in utility with international trade, compared to domestic autarky, need not exist.

Several developed countries are witnessing a trend towards an increasing gap in the earnings between skilled and unskilled workers. Though it is widely recognised that human capital formation programs through education and training should be strengthened in the presence of increasing wage...

We incorporate equilibrium unemployment due to imperfect matching into a model of trade in intermediate inputs (Ethier (1982)). Firms are assumes to be price takers and their size is given by technology. Firms enter the market as long as expected profits cover the search cost they incur...

In international trade aswell in the "New Economic Geography", country size is represented solely by the size of the country’s population. A notable exception is the paper by Shachmurove and Spiegel (1995).

In this paper, we analyze the trade war between two large countries when the trade policy is decided through majority voting. We show how the trade war equilibrium depends on the median voter production factor relative endowment. We compare this equilibrium to the one analyzed by Johnson where...

The paper shows that global pollution need not rise under free trade in goods and/or emissions even in the complete absence of income effects. Differences in environmental concerns across the countries lead to differences in the pollution-intensity of production and thus generate the possibility...

In this paper, we empirically analyze the evolution of firms’ productivity and how the efficiency changes with variations in the inputs’ origin. Using firm-level information on a sample of Irish firms, we assess the importance of the imported inputs’ quota for a firm’s efficiency, as...
