APPENDIX 20L vi PREFACE External economies and diseconomies considered jointly will, in this thesis, be called externalities. An externality, for the moment, may be defined as an effect on the cost structure of a firm which is not attrib utable to the action of that firm. Such effects may raise or lower costs. The following question is to be considered. Do externalities affect economic development and if so, in what manner? Incidental to this inquiry it is necessary to examine whether externalities are likely to advance or retard the rate of economic growth. There are two views. On the one hand there are those who regard externalities as important. This group includes, to name only a few, m Scitovsky (192), Chenery (29), Colin Clark (36), Hirschman (95), Islam (103), and Schumpeter (189). (Only Schumpeter and Hirschman argue that externalities systematically promote economic development; the others apparently believe the converse.) On the other hand, a group of economists including Fleming (66), Stockfish (205), Meade (137), Knight (116), and Young (236) appear to regard externalities, at least in pure competition, as so insignificant that it is difficult to find any realistic and con vincing examples. Moreover, there is confusion over whether externalities should be defined as attributable to a general range of market imperfec tions (including fewness of competitors), as is believed by Bator (9), or as attributable almost exclusively to dynamic factors as is believed by Ellis and Feliner (55), Thus, although a large number of articles concerned with externalities have been published, the subject is still somewhat confused. vii In this study, the problems have been approached on two fronts. First it seemed necessary to examine the relationship of externalities to economic development using theory. This is done in chapters one to five. Problems are delimited in chapter one, while chapter two provides a review and synthesis of the literature—though this review is more con cerned with externalities than with economic development. The evolution of externality concepts has been closely related to both socialist thinking and welfare economics, as a study of Pigou's Economics of welfare (159) or Baumol's Welfare economics and the theory of the state (12) will confirm. Chapter three, therefore, is an attempt to apply modern welfare concepts to the problem. This procedure is more useful than might at first be imagined, because it helps a good deal in resolving definitional problems. In fact the definitions throughout, reflect the analysis of chapter three. Chapters four and five attempt to relate the externality concepts reviewed and extended in earlier chapters to problems of economic develop ment. It must be admitted that this section is more closely related to economic growth (as opposed to development) than is desirable and that in most places the argument proceeds little beyond comparative statics. But it does develop meaningful concepts for statistical examination. The second approach to externalities in development has been empir ical. This part of the study follows concepts developed in the earlier theoretical part, but it is only partly a parallel study. It is much narrower in scope and much more detailed. But even so it is cast in terms of large aggregates so that the econometric procedure involves a number of assumptions and estimates that are not as neat as one might desire. viii The empirical part involves, first, an examination of how frequent and important are economies of scale; second, a method for estimating marginal costs to the industry of increments in output is developed; third, an attempt is made to estimate the extent of pecuniary external ities for various Canadian industries and to determine whether these accrue in such a manner that industrial expansion can be self-financing. The data on which this empirical work is based is not of uniformly high quality and the results must be interpreted with caution. But it may be concluded that, if prices to the industry are assumed constant, falling costs (in the industry) are fairly common. Pecuniary external economies (funds which are potential sources of internal financing) vary a good deal from one industry to the next and these variations do not appear always to correspond to capital intensity or to capital longevity. To the extent that they do not, the capital market is called upon to redirect the flow of investment funds. It is possible to conclude that economic growth may be less than is achievable because of externalities. However, because development implies an increase in welfare, it is not clear that externalities do, in fact, interfere with economic development. It is clear that they might under certain circumstances, but that is a different matter. Pecuniary exter nalities are much easier to treat than technological externalities and one may even go some distance toward quantification of the former. But quantification of technological externalities appears remote. 1 I. INTRODUCTION A. Background of Externalities in Economic Development 1. Purpose This study is an attempt to clarify the relationship between exter nalities and economic development. It is not clear whether externalities are important in the study of growth and development, nor is it clear whether externalities are more important in developed than underdeveloped regions, and finally it is not clear whether the presence of externalities impedes development and growth or actually aids development and growth. All these problems need to be examined both theoretically and, where possible, empirically. But while externalities have been the subject of a considerable volume of literature, and while economic development has recently been extensively investigated, there has been relatively little work devoted to the manner in which the two are related. This situation prevails, despite frequent reference in the development literature to external economies and diseconomies.
