This volume brings together and expands on a body of research that I began in the early 1960s and have continued up to the present. It deals mainly with shiftwork-work that is performed during other than normal daytime hours. Shiftwork is a characteristic of economic life in the United States and abroad that has increased in importance over the years; according to the Bureau of Labor Statistics, one out of five full-time and part-time employees in the United States works on shifts. My interest in this field concerns fixed capital, specifically, changes in weekly hours worked by capital over long periods of time, and the signifi cance of those changes in the measurement oflong-run productivity change. In studies of growth, the measurement of capital input-by capital stocks or the services yielded by those stocks-typically makes no allowance for the changing hours worked by capital. Capital services are assumed to be propor tional to the stocks. Consequently, in analyses of output growth in a growth accounting framework, the effect of longer capital hours is a component of multifactor or total factor productivity growth.

Normative Social Theory James M. Dean and A. M. C. Waterman University of Manitoba 1. Economics and Religion Once Again This hook is a sequel to Economics and Religion: Are They Distinct? (Brennan and Waterman 1994). That volume was motivated by a frustration born of many disappointing encounters between economists and theologians in the 1980s. Can bishops, synods, and other voices of organized religion bring any interesting (and disinterested) contribution to the public policy debate? If so, what is the relation of their contribution to that of the purely "secular" knowledge economists believe they can supply? Can economists bring any interesting (and disinterested) contribution to the public policy debate? If so, what is the relation of their contribution to the fundamental values that inform social ethics and that are still guarded to a large extent by religious tradition? All too often the two sides talked at cross-purposes. Well-intentioned economists coexisted for a few hours or days with well intentioned theologians whose manner of conceiving social reality was radically incompatible with their own. There seemed to be no common ground. The first requisite of any genuine conversation is an agreed conceptual framework that is able to accommodate the peculiar social vision both of the economist and of theologian, and to display the logical relation between the two."

In 1987 the Swedish National Board for Technical Development (STU, later becoming the Swedish National Board for Industrial and Technical Development, NUTEK) initiated a study of Sweden's Technological Systems and Future Development Potential. A comprehensive, interdisciplinary study was envisioned, yielding not only useful insight but also a permanent competence base for future analyses of technological systems and technology policy in Sweden. Three leading Swedish research institutes were invited to participate: the Industrial Institute for Economic and Social Research in Stockholm, the Department ofIndustrial Management and Economics at Chalmers University of Technology in Gothenburg, and the Research Policy Institute at the University of Lund. I was invited to direct the project. The project group decided to focus initially on a particular technological system, namely factory automation, to be followed by similar studies of other systems. Numerous publications have resulted from the project thus far. The current volume represents a summary of our work on factory automation. It consists of several original essays and of some previously published papers which have been edited, in some cases substantially, in order to form a comprehensive and coherent picture of a technological system. To our knowledge, this is the first in-depth analysis of a technological system designed as a component of a systematic study of technological systems more generally. At the time of this writing, three further studies on electronics and computers, pharmaceuticals, and powder technology are under way, to be published in a later volume.

th This book is published to commemorate the 50 Anniversary of the S.S. Huebner Foundation for Insurance Education. Administered at the Wharton School of the University of Pennsylvania, the Huebner Foundation was established in 1941 to strengthen insurance education at the collegiate level by increasing the number of professors specializing in insurance and enriching the literature in the field. The financial support of leading life insurance companies has enabled the Foundation to provide post-graduate education for prospective insurance teachers and scholars. Through its fellowship program, the Foundation supports students in the Ph.D. program in Risk and Insurance at the Wharton School. The success of the Foundation is measured by the accomplishments of its alumni. Former Huebner Fellows play leading roles in every major area of insurance education. Fellows teach insurance to tens of thousands of undergraduate and MBA students each year and have written hundreds of books and thousands of articles on insurance. Fellows hold leadership positions at the American College, the Life Office Management Association, and the Certified Employee Benefit Specialist Program. The Foundation was created in honor of Dr. Solomon S. Huebner, a pioneer in insurance education. Dr. Huebner taught the first organized course on the economics of insurance ever offered at the collegiate level in 1904. An internationally recognized author and teacher, Dr. Huebner had a profound impact on both insurance education and the insurance industry. He served on the faculty of the Wharton School for more than nearly fifty years.

Regulations to promote health and safety may be costly relative to the expected health and safety benefits, and may actually have negative effects on health and safety. These negative effects, or costs, may be due to reduced private spending on health and safety, moral hazard, or the creation of new risks. This volume considers the use of costs--benefit analysis, risk--risk analysis, and health--health analysis to determine the mortality cost associated with regulatory expenditures.

Do marijuana users cut back on consumption when the price rises? To what degree is marijuana consumption related to drinking and tobacco usage? What would happen if marijuana were legalised and taxed in the same way as alcohol and tobacco? Is marijuana priced in a similar way to other goods? Economics and Marijuana deals with these and other questions by drawing on a rich set of data concerning the consumption and pricing of marijuana in Australia, a country where the drug has been decriminalised in some, but not all, states. The book applies the economic approach to drugs to analyse consumption, pricing and the economics of legalising the use of marijuana. The result is a fascinating analysis of this widely used, but little understood illicit drug that provides much needed information and policy advice for a wide range of readers, including economists, policy makers and health professionals.

Future Directions in Postal Reform brings together leading practitioners, world-wide postal administrations, and the courier industry, as well as a number of regulators, academic economists, mailers, and lawyers, to examine some of the major policy and regulatory issues facing the postal and delivery industry. Issues addressed include international postal policy; the universal service obligation; regulation; competition, entry, and the role of scale and scope economies; the nature and role of cost analysis in postal service; productivity; interaction of law and economics; and future technologies and service standards.

The origin of this work is to be found in the cyclostyled course on 'The optimal allocation of resources in the firm and in the Nation' taught by Mr Boiteux at the Centre d'Etudes des Programmes Economiques (C. E. P. E. ), Paris from 1957 to 1960. Of course, several successive later rewritings and a great many additions have profoundly altered the initial version: starting from a remarkably clear and concise exposition of eco nomic theory, we have ended with a book that is several hundred pages long. It is not at all certain that Mr Boiteux would recognise this intellec tual sponsorship. Nor is it certain that the gain in information justifies such an increase in size. However that may be, the initial plan has survived. Without Mr Boiteux this book would never have been undertaken: it is a pleasant duty for us respectfully to acknowledge our debt to him here. Microeconomic analysis, that is to say that analysis which results from the study of the behaviour and activities of individual decision-units, was for a long time the main concern of the neo-classicists. Quite recently the introduction of macroeconomic theory, dealing with aggregate quan tities, seemed to relegate it to second place. But this is not where it belongs: we tend to agree with Mr Raymond Barre that there are "two different scales of analysis that complement rather than contrast with one another.""

The book is divided into three major sections. The first presents a theoretical discussion that underlies the other essays. The second section deals with privatization issues from the perspective of the United States. The third describes research addressed to the U. K. and Canada. In the first chapter, Richard Zeckbauser and Murray Horn develop a wide-ranging theoretical framework for assessing the capabilities and role of state-owned enterprises; it provides a foundation for the analyses that follow. In The Control and Perfonnance o[ State-Owned Enterprises , they describe state-owned enterprises as an extreme case of the separation of ownership and control. The focus is on management --the incentives it faces and the conflicts to which it is subjected. The distinguishing characteristics of public enterprise, the authors suggest, give it a comparative advantage over both public bureaucracy and private enterprise in certain situations. They argue that legislators are more likely to prefer SOEs over private enterprise when the efficiency of private enterprise is undermined by regulation or the tbreat of opportunistic state action, when the informational demands of subsidizing private production to meet distributional objectives are high, when it is difficult to assign property rights, or when state ownership is ideologically appealing. These considerations suggest why SOEs are usually assigned special rights and responsibilities, and they help explain observed regularities in the distribution of SOEs across countries and sectors. Zeckhauser and Horn apply principal-agent theory to identify the key factors underlying the performance of state-owned enterprises.

This volume is a compilation of essays by prominent economists in the area of household and family economics. The volume attempts to cover some areas in the field and focuses on topics such as income determination and the intergenerational transmission of income generation, the changing role of women in the labor force, fertility, and income tax treatment of the family. Each essay is followed by a discussion of part, or all, of its contents.

All humans eventually die, but life expectancies differ over time and among different demographic groups. Teasing out the various causes and correlates of death is a challenge, and it is one we take on in this book. A look at the data on mortality is both interesting and suggestive of some possible relationships. In 1900 life expectancies at birth were 46. 3 and 48. 3 years for men and women respectively, a gender differential of a bit less than 5 percent. Life expectancies for whites then were about 0. 3 years longer than that of the whole population, but life expectancies for blacks were only about 33 years for men and women. At age 65, the remaining life expectancies were about 12 and 11 years for whites and blacks respectively. Fifty years later, life expectancies at birth had grown to 66 and 71 years for males and females respectively. The percentage differential between the sexes was now almost up to 10 percent. The life expectancies of whites were about one year longer than that for the entire population. The big change was for blacks, whose life expectancy had grown to over 60 years with black females living about 5 percent longer than their male counterparts. At age 65 the remaining expected life had increased about two years with much larger percentage gains for blacks.

On May 20, 1976, the Economics Department of the City College of the City University of New York held its fourth annual conference. Eight papers followed by eight com ments were delivered on the topic of "Economics of Informa tion." These papers and comments are published in this volume along with a brief introduction. This publication has been made possible by income from the Harry Schwager Fund. My colleagues in the Economics Department have been generous when called upon to read and evaluate the papers. Professor Morris Silver, chairman of the department, was helpful at each stage of the project. Bob Leiter, my colleague and joint editor of these papers, died on August 19, 1976, while we were in the process of editing this volume. He was instrumental in organizing the Economics Department's annual conferences from their beginning in 1973 and for editing or jointly editing the con ference volumes. The Economics Department's Memorial Resolution, which follows, best expresses our sense of loss at his premature death."

Financial Risk and Derivatives provides an excellent illustration of the links that have developed in recent years between the theory of finance on one hand and insurance economics and actuarial science on the other. Advances in contingent claims analysis and developments in the academic and practical literature dealing with the management of financial risks reflect the close relationships between insurance and innovations in finance. The book represents an overview of the present state of the art in theoretical research dealing with financial issues of significance for insurance science. It will hopefully provide an impetus to further developments in applied insurance research.

This volume brings together academic economists and lawyers to evaluate and compare the regulation of telecommunications markets in Germany and the United States. The unifying theme in all of the pa pers is that the goal of public policy in this area should be to make the broadest and most functional competition possible by means of an ap propriate regulatory framework. Because the European and American telecommunications markets are becoming more intertwined each day, the issues addressed in this volume will be topical to the business, government, and academic communities for some time. For the chairman of the Monopoly Commission, Wernhard Moschel, the opening of the German telecommunications market has been successful in principle. This is clearly recognizable in the case of the competition in long-distance transport. Based on the view that the regulatory authority should make itself obsolete, Professor Moschel advocates an incremental review and gradual reduction of regulation."

This collection of thirteen essays on social ethics and normative economics honouring Serge-Christophe Kolm's seminal contributions to this field addresses the following questions: How should the public sector price its production and services? What are the normative foundations of criteria for comparing distributions of riches and advantages? How should intergenerational social immobility and inequality in circumstances be measured? What is a fair way to form partnerships? How vulnerable to manipulation is the Lindahl rule for allocating public goods? What are the properties of Kolm's ELIE tax proposal? Would the addition of EU-level income taxes enhance equity? How should we compare different scenarios for future societies with different population sizes? How can domain conditions in social choice theory be justified using Kolm's epistemic counterfactuals? How can Kolm's distributive liberal contract be implemented? What are the implications of norms of reciprocity for the organization of society? The answers to these questions give major insight into the state-of-the-art of social ethics and normative economics and are thus an indispensable source for researchers in both of these fields.

Cost Structure and the Measurement of Economic Performance is designed to provide a comprehensive guide for students, researchers or consultants who wish to model, construct, interpret, and use economic performance measures. The topical emphasis is on productivity growth and its dependence on the cost structure. The methodological focus is on application of the tools of economic analysis - the `thinking structure' provided by microeconomic theory - to measure technological or cost structure, and link it with market and regulatory structure. This provides a rich basis for evaluation of economic performance and its determinants. The format of the book stresses topics or questions of interest rather than the theoretical tools for analysis. Traditional productivity growth modeling and measurement practices that result in a productivity residual often called the `measure of our ignorance' are initially overviewed, and then the different aspects of technological, market and regulatory structure that might underlie this residual are explored. The ultimate goal is to decompose or explain the residual, by modeling and measuring a multitude of impacts that determine the economic performance of firms, sectors, and economies. The chapters are organized with three broad goals in mind. The first is to introduce the overall ideas involved in economic performance measurement and traditional productivity growth analysis. Issues associated with different types of (short and long run, internal and external) cost economies, market and regulatory impacts, and other general cost efficiencies that might impact these measures are then explored. Finally, some of the theoretical, data construction and econometric tools necessary to justify and implement these models are emphasized.

The Telecommunications Act of 1996 envisioned a competitive free-for-all in the U.S. telecommunications industry with removal of barriers to entry in local telecommunications markets and the lifting of the artificial restrictions that kept the Regional Bell Operating Companies (RBOCs) out of the interLATA long-distance market. After close to 5 years, only one RBOC has been granted permission (controversially) to enter the interLATA market, and local competition has yet to provide most consumers with meaningful choices. In addition, the wave of mergers across the industry has raised the specter of putting the former Bell System back together again. Policymakers now openly question whether the Act can deliver what it promised. Three principal themes are developed in this book. First, there has been a coordination failure between Congress and the FCC in translating the principles embodied in the Act into practice. The authors provide evidence for this by analyzing stock market reactions to legislative and regulatory actions. This coordination failure was largely predictable, given the ambiguity in the Act, as well as conflicting jurisdictions between the FCC and the states. Second, the Act calls for wholesale prices to be `based on cost.' Regulators adopted a costing standard (TELRIC) that provides a means to subsidize competitive entry in local telephone service markets. The ready adoption of the TELRIC standard by regulators is shown to be tied to the third theme: price cap regulation provides regulators with `insurance' against the adverse effects of competition in local telephone markets. Statistical analysis reveals that regulators in price cap states set uniformly lower unbundled network element prices (lower barriers to entry) in comparison with regulators in rate-of-return and earnings sharing states. The result is a triumph of regulatory processes over market processes - the antithesis of the purpose of the Act.

Competitive Transformation of the Postal and Delivery Sector is an indispensable source of information and analysis on the current state of the postal and delivery sector. It offers current insights of leading researchers and practitioners into strategy and regulation as well as the economics of this sector. Issues addressed include national and international perspectives, financial viability, the universal service obligation, regulation, competition, entry, the role of scale and scope economies, the nature and role of cost and demand analysis in postal service, productivity, interaction of law and economics, human resources, transition and reform issues. The papers in the book were selected from the papers presented at the 11th Conference on Postal and Delivery Economics, Toledo, Spain, June 4-7, 2003.

In recent years, choice no-fault has emerged as a popular but controversial proposal for addressing the problem of high automobile insurance rates. Choice plans offer consumers the option of a lower-cost insurance policy with restrictions on filing lawsuits or a higher-cost policy with full tort rights. Some American states have implemented choice programs, and major federal choice legislation is now pending in the United States Congress. Choice no-fault has caught the attention of policy makers, the insurance industry, and academics. Until now, however, no single book has pulled together the available research on the topic. The Economics and Politics of Choice No-Fault Insurance fills that gap. Edited by scholars from different disciplines, each of whom has written extensively on automobile insurance issues, the book includes some of the best work in the area. Former Massachusetts Governor and presidential candidate Michael S. Dukakis wrote the foreword. Contributors include University of Virginia Law Professor Jeffrey O'Connell, widely considered the `father of no-fault,' as well as authors of the influential RAND study of the potential effects of choice no-fault on insurance rates. The book chapters, most of which were written especially for this volume, cover topics ranging from the impact of choice no-fault on accidents and driving behavior, to the effects of choice on medical care usage, to alternative approaches for resolving accidents involving both `no-fault' and `tort' electors, to the political feasibility of choice legislative proposals. Emphasis on the potential advantages of choice no-fault is balanced by consideration of possible ill effects.

Firms do not patent every invention. In many cases they rather rely on trade secrecyorothernon-legalmeanstoprotecttheirintellectualproperty, i. e. the returns on their investments in research and development (R&D). A patent confers to its ownerthe exclusiverights to prevent third parties frommaking, using, o?ering for sale, selling, or importing for these purposes the patent protected product (Art. 28, Agreement on Trade-Related Aspects of Int- lectual Property Rights (TRIPs)). In exchange for the temporary monopoly which is securedby this protection, the patentee has todisclose the invention in a manner su?ciently clear and complete for it to be carried out by a p- son skilled in the art (Art. 83, European Patent Convention (EPC)). Thus every patent has the drawbackof a possible loss of a technologicalleadership caused by the mandatory disclosure of formerly proprietary knowledge. The patentee has to fear that this transfer of enabling knowledge included in the patent description may bene't his rivals by facilitating their rapid catch-up. The relevance and actual enforcement of the disclosurerequirement is und- lined by the European Commission's Green Paper on Innovation (European Commission (1996)). In the so-called Route of Action 8 on the promotion of intellectual and industrial property it is stated that a desirable action should be the"promotion of patent information services as a method of technology watch based, in particular, on the information system set up by the European Patent O?ce"(European Commission (1996), p. 42).

Empirical Studies in Industrial Organization brings together leading scholars who present state-of-the-art research in the spirit of the structure-conduct-performance paradigm embodied in the work of Leonard W. Weiss. The individual chapters are generally empirically or public policy oriented. A number of them introduce new sources of data that, combined with the application of appropriate econometric techniques, enable new breakthroughs and insights on issues hotly debated in the industrial organization literature. For example, five of the chapters are devoted towards uncovering the link between market concentration and pricing behavior. While theoretical models have produced ambiguous predictions concerning the relationship between concentration and price these chapters, which span a number of different markets and situations, provide unequivocal evidence that a high level of market concentration tends to result in a higher level of prices. Three of the chapters explore the impact of market structure on production efficiency, and three other chapters focus on the role of industrial organization on public policy. Contributors include David B. Audretsch, Richard E. Caves, Mark J. Roberts, F.M. Scherer, John J. Siegfried and Hideki Yamawaki.

The main objective of this book is to restate the important theories and evidence from economic analysis concerning intergovernmental fiscal issues. More importantly, the second objective of the book is to identify gaps in knowledge, empirical uncertainties, and missing theoretical structures and then to establish a preliminary agenda for new research on this topic. The book is organized in two sections. The first covers the core body of intergovernmental fiscal relations, including optimal size for jurisdictions and assignment of public sector functions, the formulation and execution of tax policy in an intergovernmental setting, and the appropriate structure and use of intergovernmental transfers. In the second section, the core knowledge is applied to four major policy areas: education, welfare, fiscal interaction in urban areas, and economic development. In thinking about a new research agenda, the authors call for more current and authoritative estimates of fiscal incidence, including interjurisdictional spillovers, for more fundamental research about the federation process and effects of consolidation, for new evidence about the long run, general equilibrium effects of interjurisdictional competition, and for basic research about the choice process and establishment of intergovernmental fiscal institutions and policies by federal and subnational governments.

Studies in Consumer Demand - Econometric Methods Applied to Market Data contains eight previously unpublished studies of consumer demand. Each study stands on its own as a complete econometric analysis of demand for a well-defined consumer product. The econometric methods range from simple regression techniques applied in the first four chapters, to the use of logit and multinomial logit models used in chapters 5 and 6, to the use of nested logit models in chapters 6 and 7, and finally to the discrete/continuous modeling methods used in chapter 8. Emphasis is on applications rather than econometric theory. In each case, enough detail is provided for the reader to understand the purpose of the analysis, the availability and suitability of data, and the econometric approach to measuring demand.

THE JANUS-FACE OF RACE: REFLEC- TIONS ON ECONOMIC THEORY Patrick L. Mason and Rhonda Williams Many economists are willing to accept that race is a significant factor in US eco nomic and social affairs. Yet the professional literature displays a peculiar schizo phrenia when faced with the task of actually formulating what race means and how race works in our political economy. On the one hand, race matters when the dis cussion is focused on anti-social behavior, social choices, and undesired market outcomes. Inexplicably, African Americans are more likely to prefer welfare, lower labor force participation, and unemployment. On the other hand, race does not matter when the subject of discussion is economically productive or socially accept able activities and legal market choices (for example, wages and employment). This Janus-faced construction of race is maintained by economists' stubborn ad herence to the market power hypothesis. The market power hypothesis asserts that racial discrimination and market competition are inversely correlated. Discrimina tory behavior will persist only in those sectors of society where the competitive forces of the market are least operative. When applied to the labor market, the mar ket power hypothesis suggests that pre- and post-labor market decisions represent disjoint sets. On average, members of a disadvantaged social group may accumulate a lower amount of or a lower quality of productive attributes because of discrimina tion in marital, residential, or school choice, or because of substantial animosity in day-to-day interpersonal relations with members of a privileged group.
