Comparison of Input–Output, Input–Output + Econometric and Computable General Equilibrium Impact Models at the Regional Level

Guy R. West

Economic impact studies are a common practice—indeed, a necessary prerequisite in many cases of project development—in Australia. Although input–output (IO) is still regarded as the ‘bread-and-butter’ model for these types of study, attention in recent years has turned towards more sophisticated models, the main contenders being integrated IO + econometric and computable general equilibrium models. All these models, which are often promoted as substitutes, exhibit characteristics which are theoretically and empirically appealing, yet questions have been raised with respect to the different approaches, with apparently little awareness at the practitioner level as to the extent of these differences. This paper compares the three models and demonstrates that the differences can be quite substantial, even when the models rely on the same database and are subjected to the same impact scenario.

Economic significance of tourism in Queensland

Guy R. West

The last decade has seen a strong growth in tourism activity in Queensland, Australia, with significant increases in visitor arrivals, tourist spending, and investments in infrastructure. The analysis of tourism to date has traditionally been handled in an input-output framework which has two major drawbacks: its static and linearity assumptions. This study estimates the economic significance of tourism activity in the Queensland economy in an integrated modelling framework, which combines the social accounting (cross-sectorial) matrix with econometric (time-series) relationships. This provides the basis for a much more comprehensive analysis of tourism activity and, as such, is superior to the traditional input-output analysis.

Regional Trade Estimation: A Hybrid Approach:

Guy R. West

This article presents an overview of the hybrid approach to the construction of regional input-output tables. As an example, the Australian GRIT system is described in some detail. Some of the shortcomings and weaknesses of the current models are discussed, together with suggestions for future research.

Queensland State Impact and Projection Model: The Household Sector

Guy R. West

The Queensland Impact and Projection model is an integrated input–output econometric model of the Queensland economy. Its purpose is to complement a conventional input–output model for analyzing economic impacts at the state level. This paper provides an overview of some of the methods used to model the household sector in an input–output framework, before describing the approach taken in the Queensland model. Some results which support the empirical performance of the model are also provided. It is demonstrated that the integrated model is a viable alternative and improvement on the conventional input–output model. The results are consistent with the static input–output model and conform to expectations about how the economy responds in real impact situations.

Generation of Regional Input-Output Tables (Grit): An Introspection

Guy R. West

ABSTRACT GRIT is a hybrid technique for deriving regional input-output tables. Since its emergence in 1977, the tables and the technique have been widely used by various research organizations. During that period, however, there has been little critical appraisal of the technique or the individual steps involved. This paper outlines some of the shortcomings found inherent in the original GRIT procedure and the subsequent revisions incorporated as a result of empirical and applied experimentation Many of these conclusions are equally applicable to general regional input–output analysis.

The spatial organization of production: An input-output perspective

Geoffry J.D. Hewings; Guy R. West; Michael Sonis; Randall W. Jackson

Imagine an economy divided into n regions; as this economy grows and develops, what can be said about the way in which production changes? The input-output system of accounts-and more extensive versions of social accounting systems-provides a useful framework for examining the spatial organization of production. In this paper, several new concepts using input-output tables and their associated models are introduced in an attempt to aid this understanding. Within each economy, a fundamental economic structure (FES) is presumed to exist. The FES is comprised of a set of interactions that have the characteristics of predictability and analytical importance. The FES provides the basis for the development of a taxonomy of economies and thus the potential for describing the space-time (evolution) of the economic system. The evolution may be described by reference to a field of influence associated with change in single elements, whole rows or columns in the input-output table of the economy. These ideas are then linked with the processes of innovation diffusion through the productive system and innovation adoption in the consumption system. The presence of innovations thus provides a competitive environment and the locus of change within the system. The synergistic effects of changes in the productive and consumption components may be realized in a multiregional setting. The framework proposed provides a rich, conceptual and analytical organization for capturing system-wide effects of changes in the spatial organization of production. Potential links with the concept of a spatial multiplier, the role of industrial organization and the possibilities of spatial switching and reswitching (a la Sraffa) are also considered.

A New Approach to Identifying Structural Development in Economic Systems: The Case of the Queensland Economy

Hermann Schnabl; Guy R. West; John Foster; Averil Cook

Recently, some economists have come to view economic development as a process of ongoing structural change which has self-organisational features. What is required is evidence concerning the self-organisational character of economic development. In other words, is economic growth associated with growth in the complexity of its structure and with a parallel rise in organisational interdependence? An extended version of qualitative input-output analysis, termed Minimal Flow Analysis (MFA), is used in this paper to analyse the structural linkages and changes that have occurred in the Queensland economy over the last two decades. The MFA evidence confirms that there has been a steady increase in the complexity of the Queensland economy. Economic coordination has occurred, to an increasing extent, through market intermediation. From a self-organisational perspective, it is clear that the Queensland economy has followed a rapid and coherent developmental path, marked by the emergence of bonded structures in its core and increasing complexity on its periphery.

Modeling Structural Linkages in Dynamic and Spatial Interindustry Systems

Guy R. West

In economics, as in most other disciplines, we use models to illustrate complex relationships among economic variables and other related objects, such as the environment. A model is just a simplified characterization of reality. Like a road map, it highlights the main features of interest but treats as background those characteristics not crucial to the purpose at hand. Through simplification, less is held in view so that more can be understood of what is retained.

Structural change in the Queensland economy: An interindustry analysis

Guy R. West

Abstract This paper attempts a tentative analysis of the structural changes which have occurred in the Queensland economy over the last two decades. An extended form of linkage analysis is used to provide a picture of the changing economic landscape. The data used is a series of input-output tables constructed for the period 1973-4 to 1992-3. The Queensland economy has followed a rapid development path, and continues to grow strongly, yet the evidence suggests that rather than increasing internal complexity, a hollowing out process has begun. The contributing factors appear to be the rapid transition from mainly primary activities to tertiary with the fabricative manufacturing stage largely being overpassed, together with significant - improvements in labour productivity, resulting in a greater level of outsourcing of inputs into the productive system than would otherwise be the case with a well developed manufacturing base. Increased globalisation will speed up the hollowing out process which has significant policy implications for Queensland.

Spatial and Sectoral Income Distribution Effects in an Interindustry-Econometric Framework: The Case of Queensland

Guy R. West

Queensland is a very diversified and decentralized state, ranging from a very arid and sparsely populated inland to densely populated temperate zones in the south-east to tropical rainforest areas in the north. Renowned as “The Sunshine State”, with its images of mild climate and pristine beaches stretching for miles, it is often the envy of residents in the “rust-belt” areas of southern New South Wales and Victoria. Unfortunately, its economic performance has not always lived up to the same reputation. High levels of unemployment Australia-wide have seen increased migration from retirees (often forced) and the “structurally” unemployed into Queensland from the southern States. If one has to live on the dole, one might as well do it in comfort.
