Disruptions to the freight transportation system are costly due to freight's critical relationship to economic productivity. This research will analyze the current methods of estimating the economic impacts of disruptions to the freight transportation system. A review of existing literature will...

Ghosh's model is discussed in this paper under two alternative scenarios. In an open version we compare it with Leontief's model and prove that they reduce to each other under some specific productive conditions. We then move onto reconsidering Ghosh's model alleged implausibility and we do so...

This paper deals with the problem of choosing techniques. When we refer to the problem of choosing techniques, we actually refer to choose from a set of given production processes-techniques -according to a specific criterion- the optimum one. The criteria which are going to be presented are the...

In this paper we attempt an empirical application of the multi-region input-output (MRIO) method in order to enumerate the pollution content of interregional trade flows between five Mid-West regions/states in the US –Illinois, Indiana, Iowa, Michigan and Wisconsin – and the rest of the US....

Based on C.Bidard’s and E.Klimovsky’s “Switches and Fake switches in methods of production”, an attempt will be made to show if fake switch points (as named) are in fact, and opposite of what Bidard and Klimovsky claim, real switch points.

Purpose – The purpose of this paper is to demonstrate the value of computable general equilibrium (CGE) modeling for impact analysis of real estate developments and redevelopments. Design/methodology/approach – Uses a model constructed for Colorado to compare estimates of economic impact of...

The hybrid approach to constructing regional I-O tables is cost efficient and relatively reliable. Even though road maps as to how to prepare regional tables are available, it is important to share experiences to reveal practical pitfalls. Also, it is necessary to assess whether additional...
