The decade of the 1970's has seen substantial improvement in our under standing of the determinants of urban spatial patterns. It is typical of western science and technology of the past several centuries that these advances in urban spatial analysis have resulted from the efforts of many individuals. No one of these claims to have found the answer; rather, each contributes some additional understanding of a rather complex set of inter related phenomena. All of this most recent work, in one way or another, rests on preliminary analysis work done in the previous ten to fifteen years. Those...

The presence of nonconvexities does severe damage to conventional theories of the firm and of the individual. The essential contribution of location theory, however, is in a world in which there are such nonconvexities. If resources are distributed evenly and the usual convexity assumptions made, then economic activity would be distributed evenly; there would be no concentration of pro duction. Thus the statement that is usually made, that the standard results carry over to a world in which there is spatial choice, is too weak and fails to capture the essence oflocation theory. Nevertheless,...

This publication is concerned with two major current debates in public policy in all affluent societies. One is the widespread concern with the quality of the natural environment-the quality of air, water, land, and wilderness areas-which has expressed itself in the passage and implementation in recent years of a variety of environmental laws and regulations. A second debate concerns the adequacy of energy resources to meet the requirements of a growing economy. The requirement that industries must abate environmental pollution leads to increased costs of production and, in turn, to higher...

1. 1. Motivation This book is based on the view-tx)int that both public and private decision making, in practice, can often be ilrproved upon by means of fonnal (nonnative) decision nodels and methods. To sane extent, the validity of this statement can be measured by the irrpressive number of su=esses of disciplines as operations research and management science. Hcwever, as witnessed by the many discussions in the professional journals in these fields, many rrodels and methods do not completely meet the requirements of decision making in prac tice. Of all possible origins of these clear...

The greatest challenge facing mankind today is the immense disparity in the levels of income among people in different parts of the globe. The growth rate of income of the poor countries is consistantiy far below the rate of the advanced, industrialized nations. Due to low income and a high propensity to consume, there is very little left in these countries for investment. A major portion of the resources available is devoted to military expenditures. This continual decline in the standard of living, coupled with poverty and unemployment, will lead to social and political upheaval in these...

The research project leading to this book was initiated in the fall of 1979 when the American Council of Life Insurance (ACLI) contacted Dan McGill, chairman of the Wharton School Insurance Department, about conducting a study on risk classification in life insurance. The ACLI was concerned about legislative and judicial activity in this area and its potential effects on the life insurance industry. A meeting was held at the ACLI offices in Washington, D.C., between several members of the ACLI staff and Dan McGill and David Cummins representing the Wharton School insurance department. An...

From the beginning, the systems research movement has shown a high potential for offering a conceptual framework for the understanding of social systems. Much of this potential has been realized, but a major gap remains with regard to operational investigative aids. Developments of the last ten years with a method ological orientation and emphasis seem finally to be filling this gap. The purpose of this book is to describe the most advanced of these developments and to make them available to a wider audience. The emphasis is on developments that are primarily oriented toward interaction with...

Most of the research incorporated in this monograph was initially undertaken as part of the author's Ph.D. dissertation submitted to the School of Urban and Public Affairs, Carnegie-Mellon University. The research was funded through a Doctoral Dissertation Grant from the U.S. Department of Housing and Urban Development. The dissertation was a winning entry in the 1979-80 Ph.D. Disser tation Competition of the North American Regional Science Association, funded through a grant from the Economic Development Agency of the U.S. Depart ment of Commerce. Revisions and extensions of the initial...

In recent years the development of spatial referencing techniques in com- puter-based information systems has enormously increased the opportuni- ties that exist for the treatment and presentation of both point and interaction data. The extent of this increase has drawn attention to the need for special aggregation and clustering procedures to be developed which enable data to be grouped in an efficient way for analytical pur- poses with a minimum loss of detail. In the case of interaction data, economy of representation is particularly important as the analysis is further complicated by the...
