This thesis is an attempt to apply the technique of input-output analysis to the study of the relations between an economy and the environment which supports it. The opening chapter contains a brief justification of the use of input-output analysis for this purpose. It is argued that input-output models, which recognise many of the interactions among consumers and producers, can be extended so that they also take account of some of the interactions among consumers, producers, and the natural environment. Emphasis is placed upon the flow of materials between the environment and the economy. Waste products flow from the economy to the environment and 'free' goods flow in the opposite direction. There follows, in the second chapter, a review of the work of three writers who have explored the possibility of using general equilibrium and input-output models to study man's impact on the environment. The models presented by these economists are each found to possess unsatisfactory features. The theoretical core of the dissertation is an adaptation of two recently developed input-output models. Waste products and 'free' goods are introduced into both models in several different ways. The data requirements of the various models differ considerably and only the simplest of the models can be applied to the data on waste products and 'free' goods that are currently available. Canadian data, much of which were collected especially for this study, and the methods used in its estimation, are described in the fourth chapter. Chapter five is a summary of the results obtained from using the data on waste products and 'free' goods in conjunction with the Canadian input-output accounts for 1961. These results include estimates of the wastes produced and 'free' goods used in the production and consumption of one dollar's worth of each type of commodity manufactured in Canada. The results also include estimates of the Provincial distribution of waste products and 'free' goods that were associated with Canadian economic activity in 1961. Furthermore, an attempt is made to rank the commodities produced and consumed in Canada, in terms of the relative impact on the environment of their production and consumption. The final experiment illustrates a method of estimating the ecologic implications of changing the pattern of Canadian consumption. To show this an estimate is made of the effects of transferring 50 per cent of Canadian passenger car travel to public transportation. The last chapter of the thesis is a discussion of the uses to which the models and results might be put in formulating Government policy. Various methods are examined of bringing the production of wastes and use of 'free' goods within the realm of the market economy. It is argued that although it is generally more efficient to price the wastes and 'free' goods directly this policy can only serve as a long term goal. In the short term it is suggested that, for administrative reasons, emphasis should be placed on levying taxes on commodities so that their market prices reflect the ecologic cost of their production and consumption. A schedule of the relative sizes of such taxes is estimated using a model developed for the purpose together with the data collected as part of this study. In conclusion, the overall purpose of the dissertation is to suggest a method of analysis rather than to present comprehensive results. The results which are obtained are intended to be no more than indicative of what would be possible if more accurate and comprehensive data were available. / Arts, Faculty of / Vancouver School of Economics / Graduate

This thesis examines the existing theories and applications of Multivariate Statistical Process Control, outlines areas of difficulty and proposes a new technique of multivariate process control chart with input-output relationship for optimal process control. The process control techniques developed up to the present time focused on the fast detection of out-of-control signals, and achieved considerable success in that respect. The techniques reported on multivariate process control thus far include extensions of univariate process control charts to their multivariate counterparts, ranging from classical Shewharts charts to modern Cumulative Sum Process Control charts. Alternative approaches in this area include Principal Component Approach, Partial Regression approach, Baysian modelling and sequential tests on detection of change points. Although each method has its own limitation, these new developments have significantly contributed to the achievement of a constant high quality of products and services. The techniques of process control are yet incomplete. They require continuous attention, as production and service technologies are being continuously developed.In particular, the level of automation, re-engineering of production processes and ever demanding economic optimality of technology demand the re-engineering of statistical process control. The CFM chart developed in this thesis would open the door to this area of science and lays a critical foundation for future research / Doctor of Philosophy (PhD)

Doctor of Philosophy (PhD) / The purpose of this research is to help understand the key relationships in an evolving economic structure that are driving resource use and greenhouse gas emissions in Australia. The approach involves looking at the factors and relationships that underpin economic growth in Australia. This research seeks to understand the changes in these factors by taking a historical perspective to the determinants of environmental impact through an investigation of structural changes over a period of 30 years. A detailed model is developed using the macro-economic tool of input-output analysis. This model makes it possible to investigate inter-relationships and intra-relationships between sectors of the environment, the economy and the population at disparate scales.

The purpose of this study is to test the hypothesis that centrally- planned economies are characterized by what is called a bias towards absorption of natural resource intensive products (NRP) which is said to affect in turn the commodity structure of their foreign trade. While the study includes a detailed analysis of foreign trade structures and the absorption of NRP by final consumers, it is the intermediate demand for NRP and its determinants which are emphasized. Following the suggestions in the literature that the technologies used by the centrally- planned and market-type economies are different, the role of technology in determining intermediate demand for NRP has been examined in detail. Bias is defined here in terms of inter-country differences and the present comparison involves a case-study of Czechoslovakia as a centrally-planned economy and Austria as a market-type economy based on an input-output model. The use of the input-output model in inter- national comparisons of production and use of commodities has been criticized on the following grounds: (1) The distinction between technology and substitution is ignored in the model. (2) International differences in relative prices are normally ignored or assumed away in empirical work. (3) The comparisons may be severely affected by imperfections of input-output tables. This study attempts to answer the above criticism in an original way. New methods of sensitivity analysis were designed to test for the existence of the 'triangular' and other 'fundamental' properties of the technological matrices. In addition, the assumption of temporal stability of input-output coefficients is relaxed and an attempt is made to distinguish between technology and substitution with the help of the RAS method. Further analysis of the impact of relative prices on input-output flows was derived from an analysis of indirect taxation. The main conclusion of this study is that Czechoslovakia had a considerable NRP import bias which was primarily due to the pro-NRP absorption bias of final consumers. However, it is unlikely that 'excessive' aggregate demand for imports originated in 'NRP-biased' technology. This empirical analysis provides strong evidence that the production processes with regard to the use of NRP were highly similar in both countries.
