An Interdependent Framework for Integrated Sectoral and Regional Development

In most countries there is a need for a technique to develop consistent sectoral and regional scenarios for long-term planning or forecasting purposes. This paper presents a set of models designed to satisfy this requirement. The models are based on dynamic input-output theory, without the linearity constraint. The focus of these models is on long-term problems and we have therefore concentrated the analysis on scenarios of the general equilibrium type. The models have been constructed so as to be applicable also in situations of limited statistical information in terms of capital trade flow measurements. The method has been applied to market and planned economies. Numerical problems are discussed in the paper

Price Adjustments and Multiregional Rigidities in the Analysis of World Trade

This paper reviews a set of approaches to modeling interregional and international trade flows. It also suggests a framework which is capable of combining price formation mechanisms with factors which cause resistance to change and barriers to trade. In certain respects the framework adheres to the Takayama-Judge tradition, but differs by using a probabilistic framework which generates equilibrium solutions which are not perfect competition equilibria

An Overview of Regional and Multiregional Modelling in Australia

IIASA's Regional Development Group is engaged in a sequence of comparative studies in regional development modeling. The general purpose of this work is to promote an international exchange of the best experiences and most advanced knowledge in the field. This paper was prepared as a contribution to a comparative study of multiregional modeling. It gives a general overview of approaches to regional and multiregional modeling in Australia, describes the main models developed in that country, and gives their characteristics in terms of spatial focus, direction of causal links, and formal types of solution techniques

Nested Dynamics of Metropolitan Processes and Policies - MELBOURNE

BACKGROUND PAPERS FOR THE METROPOLITAN STUDY: 1 -- The Project "Nested Dynamics of Metropolitan Processes and Policies" was initiated by the Regional and Urban Development Group in 1983 and work on this collaborative study started in 1983. This series of contributions represent "entry tickets" to the Project, i.e., initial statements by authors from individual metropolitan regions that are participating in the Project's network. The aim of these papers is threefold. First, to provide some background information describing the processes of change within four principal subsystems: population, housing, economy, and transportation. Second, to identify major trends and crucial policy issues which are to constitute a focus for the subsequent analytical and modeling work. Third, to facilitate comparative studies of development paths among these regions and the dynamic interdependencies between the above subsystems. The background material contained in this paper pertains to the Melbourne metropolitan region

The Changing Economic Structure of Metropolitan Regions: A Preliminary Comparative Analysis

Contribution to the Metropolitan Study: 15 -- The project "Nested Dynamics of Metropolitan Processes and Policies" was initiated by the Regional and Urban Development Group in 1982, and work on this collaborative study started in 1983. This series of contributions to the study is a means of conveying information between the collaborators in the network of the project. The foundation of the project is a systematic comparison of dynamic phenomena in a set of relatively advanced metropolitan regions. This comparison is intended to identify key factors and observable development paths which are shared by all regions, or at least by certain subgroups of regions. In this paper, we therefore begin to assess the relative stage and speed of economic structural development in a given set of such regions. A methodology based on changing employment shares is developed to examine industrial substitution (that is, aggregate technological change) through time and over metropolitan space. The relocation and restructuring of job opportunities within or outside a metropolitan region can be interpreted in terms of industrial innovation and product cycle theory. In this way, it is possible to identify the trajectory of a global cycle of economic development in terms of each city's current economic and spatial structure and its relative speed of technological change

Advances in Spatial Theory and Dynamics

This book originates from two meetings, set apart in time but closely connected by continuing collaborative efforts between researchers in an international network. The first of these meetings took place at IIASA in October 1984, organized by IIASA's Regional Issues Project under the title "Dynamic Analysis of Spatial Development". About half of the papers in this volume were presented at that meeting. These contributions have been elaborated and revised considerably during the preparation of this volume, and can now be regarded as mature papers embracing the frontiers of spatial and economic dynamics. Another set of contributions was presented during the European Summer Institute in Regional Science held at the University of Umea in June 1986. The Summer Institute was organized by CERUM in collaboration with the Departments of Economics and Geography at the same university. The contributions have been drawn from the sessions on technological change, nonlinear dynamics in spatial networks and infrastructure development. This is reflected in the three parts of the volume (1) Competition, specialization and technological change, (2) Spatial interaction, (3) Urban and regional infrastructure

Economic Evolution and Structural Adjustment: Proceedings, Berkeley, California, USA, 1985

Since the beginning of the fifties, the ruling paradigm in the discipline of economics has been that of a competitive general equilibrium. Associated dynamic analyses have therefore been preoccupied with the stability of this equilibrium state, corresponding simply to studies of comparative statics. The need to permeate the boundaries of this paradigm in order to open up new pathways for genuine dynamic analysis is now pressing. The contributions contained in this volume spring from this very ambition. A growing circle of economists have recently been inspired by two distinct but complementary sources: (i) the pathbreaking work of Joseph Schumpeter, and (ii) recent contributions to physics, chemistry and theoretical biology. It turns out that problems which are firmly rooted in the economic discipline, such as innovation, technological change, business cycles and economic development, contain many clear parallels with phenomena from the natural sciences such as the slaving principle, adiabatic elimination and self- organization. In such dynamic worlds, adjustment processes and adaptive behaviour are modelled with the aid of the mathematical theory of nonlinear dynamical systems. The dynamics is defined for a much wider set of conditions or states than simply a set of competitive equilibria. A common objective is to study and classify ways in which the qualitative properties of each system change as the parameters describing the system vary
