Bokkapitel (refereegranskat)abstract
- In this chapter we examine various analytical approaches which are pertinent to an important area of research in which, according to Isard and Dean ([30]), regional scientists ought to be more actively involved. This is the estimation of commodity flow (or trade share) matrices across world trade networks. Although spatial variables such as distance, location and transport cost clearly have a significant impact on the quantity and structure of trade, these effects are often ignored or downplayed by international trade economists. Our task is to redress this imbalance partly by strengthening the case for combined spatial interaction-equilibrium approaches to world trade analysis.

Production and trade in interacting economies : a survey of applied equilibrium models
- 1990
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A class of models for analyses of the interaction between economic structure and transportation system in spatially separated economies is discussed. The model class, applied multisector network equilibrium models (AMNE) is presented and existing models, such as Input–Output, CGE, ICGE, SPE and FNE models, are interpreted as special cases.Especially ICGE models and a set of linearized ICGE models are considered. This type of models will have an increasing importance in studies of infrastructure investments, in particular in the context of the integration process within the European Community.

Vintage models of spatial structural change
- 1990
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In the study a class of multisector network models, suitable for simulation of the interaction between production, demand, trade, and infrastructure, is presented. A characteristic feature of the class is a vintage model of the production system. Hence, the rigidities in existing capacities and the temporary monopolies obtainable from investments in new capacity at favourable locations are emphasized.As special cases, the class contains models in the modelling traditions of "interregional computable general equilibriunT, Hspatial price equilibrium**, "interregional input-output" and transportation networks.On the demand side, a multihousehold spatial linear expenditure system is introduced. This allows for an endogenous representation of income effects of skill-differentiated labour.The models are represented by a set of complementarity problems. This facilitates a comparison of model properties and the choice of an appropriate solution algorithm.The study is mainly devoted to single period models. Such equilibrium models are interpreted as adiabatic approximations of processes in continuous time. A separation by the time scale of the processes and an application of the slaving principle should thus govern the choice of endogenous variables in the equilibrium formulation.
