Multidisciplinary economics deliberately uses the insights and approaches of other disciplines and examines what consequences their contributions have for existing economic methods, theories and solutions to economic problems. Multidisciplinary economists should be at home in their own discipline and meet the high international standards of economic teaching and research that the discipline has developed. At the same time they should be able to recognise the limits of economics and be willing to open up new horizons by following new, discipline-transcending paths on which new insights into the analysis and solutions of economic problems can be found in collaboration with representatives of other disciplines. As a result of this search, economic methods and theories may have to be adjusted in such a way that they take insights from other disciplines into account. They may even have to be replaced by methods and theories that have been developed by other disciplines.

Europeans are living longer, and fewer now remain in the labour force as they grow older. Many European countries have responded to the ensuing financial pressure by reforming their public pension systems and health care programmes. There is considerable uncertainty as to the effects of these reforms - as they typically do not alter the unfunded nature of public welfare arrangements and this uncertainty is itself costly. Not only does it undermine the credibility of public welfare programmes, but it may also distort labour supply behaviour, decisions regarding savings and capital accumulation. More generally there is uncertainty about the overall impact of ageing on welfare and society and the multiple domains in which its effects may develop. Pensions: More Information, Less Ideology builds on the existing evidence - mostly in the field of public pensions - and highlights the advantages that would be obtained by: harmonising methodologies used in the various countries to report pension outlays and forecast future pension liabilities or more generally public spending; defining common standards as to the frequency of expenditure forecasts and the length of the forecast horizons for welfare expenditures; developing European longitudinal survey of persons pre- and post retirement age, providing timely information on a wide array of decisions by individuals and household related to the ageing process and the ongoing trends.

Covering a topic of massive contemporary importance, this well written volume demonstrates how transportation strategy and environmental sustainability can be pursued in a comprehensive and harmonious, rather than unconnected and potentially conflicting, set of public policies. It applies lessons from several urban areas (e.g., Bogota, Singapore, Mexico City, Sao Paulo), including "success stories" and less successful "hard-won lessons," to a case study in Guangzhou.

Information and communication technology (ICT) is central to reforming governance, innovating public services, and building inclusive information societies. Countries are learning to weave ICT into their strategies for transforming government as enterprises have learned to use ICT to innovate and transform their processes and competitive strategies. ICT-enabled transformation offers a new path to digital-era government that is responsive to the challenges of our time. It facilitates innovation, partnering, knowledge sharing, community organizing, local monitoring, accelerated learning, and participatory development.

In Transforming Government and Building the Information Society, Nagy Hanna draws on multi-disciplinary research on ICT in the public sector, and on his rich experience of over 35 years at the World Bank and other aid agencies, to identify the key ingredients for the strategic integration of ICT into governance and poverty reduction strategies. The author showcases promising practices from around the world to outline the strategic options involved in using ICT to maximize developmental impact-transforming government institutions and public services, and empowering communities for inclusion and grassroots innovation.

Despite the ICT promise, Hanna acknowledges that reforming governance and empowering poor communities are difficult long-term undertakings. Hanna moves beyond the imperatives and visions of e-transformation to strategic design and implementation options, and draws practical lessons for policymakers, reformers, innovators, community leaders, ICT specialists and development experts.

Globalization deeply affects economic structures and raises the issue of how governments should respond to new challenges. In this book, various ways of improving the institutional setup for global governance are discussed by renowned experts. The discussion focuses on further liberalizing international trade, preventing international financial crises, and protecting global environmental systems. The advantages of free international trade as well as the fears of those who are against globalization are considered in the contributions.

This book provides an up-to-date summary of the consequences of demographic aging for labor markets, financial markets, economic growth, social security schemes and public finances in Germany, essentially reflecting the present state of knowledge in any of these areas. All contributions are written by leading experts in their fields and are based on results that emerge at the forefront of current research.

The aim of this book is to analyse specific sets of macro and structural policies in selected Eastern European countries. The book includes studies on the major Western CIS countries, Belarus, Russia and Ukraine, plus a set of cross-country and regional studies. The analysis in this book contributes importantly to the discussion about the economic prospects of the CIS countries.

Following the birth of the European Monetary Union (EMU) economists are still divided in their assessment of the ability of its key institutions to provide macroeconomic stability and foster the reforms necessary to stimulate economic growth. In this collection, experts focus on issues of fiscal policy, monetary policy and labour markets and ask: Can the stability and growth pact provide an adequate framework for the conduct of national fiscal policies? Is the ECB reacting with competence and flexibility to a rapidly changing macroeconomic environment? How do national labour markets react to the macroeconomic institutions and what are the structural reforms needed in labour markets? Blending empirical and theoretical data, this book offers one of the most comprehensive surveys of research in macroeconomic policymaking within the EMU.

Derived from the international literature on experiences with performance budgeting five elements which constitute performance budgeting as a comprehensive system can be identified in this book. This new definition is then applied to the German state level in order to investigate whether performance budgeting is effective in Germany, in detail, whether it actually leads to a reduction of public expenditure. With a survey in the state Ministries of Finance and an individually constructed panel dataset, the impact of the German performance budgeting reforms on their major aim, the enhancement of fiscal discipline, is empirically analyzed. The main result is that the potential of expenditure savings is prolonged by the enormous investments in the beginning.

Most higher education finance literature assumes that students cannot pledge their future earnings to finance their education in a free society. Investing in Human Capital, first published in 2004, challenges that assumption and explores human capital contracts as an alternative mechanism for financing higher education. Investing in Human Capital tracks the roots of the idea behind human capital contracts, discusses the beneficial consequences they would have on students and on higher education markets, and describes how they can develop in light of the innovations that have taken place in financial markets during the last decades. The book also explores the challenges - ethical and financial - that such instruments face and offers implementation alternatives that can bring about their existence in the context of a national higher education financing programme.

Conventional wisdom warns that unaccountable political and business agents can enrich a few at the expense of many. But logically extending this wisdom implies that associated principals - voters, consumers, shareholders - will favor themselves over the greater good when 'rules of the game' instead create too much accountability. Democratic Governance and Economic Performance rigorously develops this hypothesis, and finds statistical evidence and case study illustrations that democratic institutions at various governance levels (e.g., federal, state, corporation) have facilitated opportunistic gains for electoral, consumer, and shareholder principals. To be sure, this conclusion does not dismiss the potential for democratic governance to productively reduce agency costs. Rather, it suggests that policy makers, lawyers, and managers can improve governance by weighing the agency benefits of increased accountability against the distributional costs of favoring principal stakeholders over more general economic opportunities. Carefully considering the fundamentals that give rise to this tradeoff should interest students and scholars working at the intersection of social science and the law, and can help professionals improve their own performance in policy, legal, and business settings.

David B. Smith This is a book about the application of economic theory to a unique form of social control - public utility regulation. A central theme of this work is to examine the role that economics has played in shaping the rationale and direction of regulatory practices. While economic theory has played an important role in the shaping of regulatory policy in the past, it has an even greater potential role to play in the future as the regulatory community grapples with the many challenges of a changing economic environment. This is a very timely and much needed piece of work that can serve as a reference for decision makers who are facing the challeng ing problems of deregulation and competition. This work is comprised of 13 selected articles that guide the reader from an initial discussion of why we decided to regulate certain industries in the first place to a specific analysis of what role economic theory has played in the electric, natural gas, telecommunications, and water indus tries, and whether it should be allowed to play an even more dominant role in the future. The reader is then provided with a more modern version of what economists mean by the concept of natural monopoly and a menu of policy options that will allow society to derive any benefits from such a market structure."

This volume contains original essays by outstanding scholars working within several of the dominant genres in contemporary political economy: neoclassical public finance, public choice, and Marxian analysis. Critical overviews of some of their major themes are offered in my introductory chapter and in Warren J. Samuels' concluding one, while more focused, if briefer, comments by other scholars follow each of the theoretical presen tations in chapters 2 through 4. The book's aim is to alert, inform, and possibly provoke readers to a more careful examination of the important and manifold problems of theory and analysis raised by authors whose points of entry into the subject of political economy often differ substan tially. At a time when problems of economic performance and political management frequently seem to have become not only severe but intrac table, it is not unwise to consider again the ways in which greater sense might be made of these crucial matters. The book's dialectical organization is intended to encourage readers to consider insights and objections that may not have been otherwise appar ent and, hence, to reflect in a more critical fashion upon the limitations and advantages of various visions in this complicated and sometimes disorderly field. Since I am of the opinion that no fully satisfactory syn thesis of the perspectives presented here is (probably ever) possible, no Procrustes has been summoned to make the attempt."

Sebastian Werner examines aggregate short sales and convertible bond arbitrage, which is a typical hedge fund strategy that involves a significant short position in the underlying stock of a long convertible bond position for hedging purposes. He provides insightful and new observations of the significant difference in the trading pattern, information content and resulting impact on stock returns of arbitrage- versus valuation-based short selling activities.

This book contains material that I have presented in seminars at the Universities of Bochum, Mannheim, Munich, Salerno, and Southern California at Los Angeles, the Institute for Advanced Studies in Vienna, the Max-Planck-Institute for Demographic Research in Rostock, and on various international meetings and conferences. In preparing and revising the material I have benefited from comments, discussions, and advice from several colleagues. I had particularly close and friendly collaboration with Alexander Kemnitz and Robert von Weizsicker to whom I am very grateful. I am also grateful to Michele Boldrin, Axel Borsch-Supan, Friedrich Breyer, Karen Feist, Tullio Jappelli, Leo Kaas, Marco Pagano, Gerhard Schwooiauer, Carl Christian von Weizsacker, and Wolfgang Wiegard for their comments and suggestions.

This book explores theoretical and practical implications of reflecting the fair value of liabilities for insurance companies. In addition, the contributions discuss the disclosure of these values to the financial and regulatory communities and auditing firms which are actually calculating this illusive but important variable. It combines contributions by distinguished practitioners from the insurance, accounting and finance fields, with those of prominent academics. One of the central themes of the collection is that adequate disclosure of the true economic value of insurance company liabilities is both possible and desirable. Wherever possible, the insurance valuation process is wedded with modern financial theory. For example, the use of option pricing theory is applied to insurance companies, where the true value of the firm's liabilities is a critical variable. Methods such as cash flow, earned profit and indirect discount are explored.

What made me write this book was a feeling that students of international economics needed to fill out their knowledge of the theory with work on the practice of the major international economic organizations, many of which are having a growing influence on the national economies of their members. There was no single volume given over to a concise treatment of these organizations. The annual reports of the international organizations themselves can be consulted, of course, but as a rule these are not noted for being brief and to the point (the items of importance have to be fished out of a sea of useless detail), nor do they go in for criticism of their own activities. In selecting the organizations to be dealt with in the book I was guided by the influence they exert. I have left out those whose activities consist mainly in the drafting of recommendations to which, however meritorious they may be, little or no attention is paid. Some of them are included in the Introduction, which provides a summary of a number of institutions not discussed separately in the body of the work. There are, however, two exceptions: the Organization for Economic Cooperation and Development (OECD) as the organization replac ing the Organization for European Economic Cooperation (OEEC), and the United Nations Conference on Trade and Development (UNCTAD) whose meet ings have succeeded in drawing much attention of the press."

Much has been written about the economic and political problems of countries that are in the process of changing from centrally planned systems to market systems. Most studies have focused on the economic, legal, political, and sociological problems these economies have had to face during the transition period. However, not much has been written about the dramatic changes that have to be made to the accounting and financial system of a transition economy. Accounting and Financial System Reform in a Transition Economy: A Case Study of Russia was written to help fill that gap.

This book presents 15 original papers and commentaries by a distinguished group of tax policy and tax administration experts. Using international examples, they highlight the state of knowledge of tax reform, present new thinking about the issue, and analyze useful policy options. The book 's general goal is to examine the current and emerging challenges facing tax reformers and to assess possible directions future reforms are likely to take. More specific themes include distributional issues, how to tax capital income, how to design specific taxes (e.g., the income tax, the value-added tax, the property tax), how to consider the politics and administrative aspects of tax reform, and how to combine the separate insights into comprehensive tax reform.

A comprehensive overview of weak convergence of stochastic processes and its application to the study of financial markets. Split into three parts, the first recalls the mathematics of stochastic processes and stochastic calculus with special emphasis on contiguity properties and weak convergence of stochastic integrals. The second part is devoted to the analysis of financial theory from the convergence point of view. The main problems, which include portfolio optimization, option pricing and hedging are examined, especially when considering discrete-time approximations of continuous-time dynamics. The third part deals with lattice- and tree-based computational procedures for option pricing both on stocks and stochastic bonds. More general discrete approximations are also introduced and detailed. Includes detailed examples.

This book presents a collection of papers which evaluate the achievements of the Australian Trade Practices Act 1974 in making Australian markets more competitive. The contributors have all played major roles in Australian and New Zealand antitrust actions, either as expert economic witnesses, as antitrust enforcers, as judges or as quasi-judicial administrators. No other publication presents such in-depth economic analysis of the Act and the cases decided under it in its first two decades of its operation. As well as an introductory paper, this collection includes a foreword by the Hon. George Gear, Assistant Treasurer of the Australian Government and Minister responsible for the administration of the Act, plus two broad analytical overviews of the last two decades of Australian antitrust actions by two economists who have continually been at the heart of antitrust proceedings. In addition, papers are provided which give a judicial view of the Act and economic analysis, which compare the Act with its New Zealand counterpart. Other contributions look in detail at those sections of the Act which cover mergers, misuse of market power, price-fixing and vertical practices. The book shows that the Act has had a major impact on Australian market behavior. Judges, lawyers and economists between them have produced a truly Australian approach to antitrust, which has reflected overseas trends in both law and economics, as well as developed a unique Australian flavor. The book will be of interest to academic and practicing lawyers and economists, judges and corporate executives. It will be essential reading for Australian students in undergraduate courses in antitrust law, business regulation, antitrust economics and industrial organization. It provides by far the most comprehensive economic evaluation of Australian antitrust yet published and so will be the definitive source of information on this topic for non-Australians interested in comparative antitrust legislation and enforcement issues.

A framework for financial market modeling, the benchmark approach extends beyond standard risk neutral pricing theory. It permits a unified treatment of portfolio optimization, derivative pricing, integrated risk management and insurance risk modeling. This book presents the necessary mathematical tools, followed by a thorough introduction to financial modeling under the benchmark approach, explaining various quantitative methods for the fair pricing and hedging of derivatives.

Modern option pricing theory was developed in the late sixties and early seventies by F. Black, R. e. Merton and M. Scholes as an analytical tool for pricing and hedging option contracts and over-the-counter warrants. How ever, already in the seminal paper by Black and Scholes, the applicability of the model was regarded as much broader. In the second part of their paper, the authors demonstrated that a levered firm's equity can be regarded as an option on the value of the firm, and thus can be priced by option valuation techniques. A year later, Merton showed how the default risk structure of cor porate bonds can be determined by option pricing techniques. Option pricing models are now used to price virtually the full range of financial instruments and financial guarantees such as deposit insurance and collateral, and to quantify the associated risks. Over the years, option pricing has evolved from a set of specific models to a general analytical framework for analyzing the production process of financial contracts and their function in the financial intermediation process in a continuous time framework. However, very few attempts have been made in the literature to integrate game theory aspects, i. e. strategic financial decisions of the agents, into the continuous time framework. This is the unique contribution of the thesis of Dr. Alexandre Ziegler. Benefiting from the analytical tractability of contin uous time models and the closed form valuation models for derivatives, Dr."

Consumers have always been concerned about the quality, and particularly the safety, of the foods they eat. In recent years this concern has taken on additional prominence. Consumer focus on food safety has been sharpened by reports about new risks, such as that posed by "mad cow" disease, and about more familiar sources of risk, such as food borne pathogens, pesticides, and hormones. At the same time, some consumers are in creasingly interested in knowing more about how their food is produced and in selecting products based on production practices. Some of the questions consumers are asking in clude whether food is produced with the use of modern biotechnology, whether it is or ganically produced, how animals are treated in meat and egg production systems, and whether food is produced using traditional methods. Recent trends also show increased consumer demand for a variety of food products that are fresh, tasty, and available on a year-round basis. This has fostered increased global trade in food. For example, consumers in temperate climates such as North America are able to buy raspberries throughout the year, and Europeans can enjoy South American coffee. Trade in processed food products is actually increasing more rapidly than trade in agricultural commodities, further addressing the demand for variety among consumers."

The United States is moving toward a possible catastrophic fiscal collapse. The country may not get there, but the risk is unmistakable and growing. The 'fiscal language' of taxes, spending, and deficits has played a huge and under appreciated role in the decisions that have pushed the nation in this dangerous direction. Part of the problem is that by focusing only on the current year, deficits permit politicians to ignore what is looming down the road. The bigger problem lies in the belief, shared by people on the left and the right alike, that 'tax cuts' and 'spending cuts' lead to smaller government, when in fact the characterization of any new policy as a change in 'taxes' or in 'spending' is purely a matter of labeling. This book proposes a better fiscal language for US budgetary policy, rooted in economic fundamentals such as wealth distribution and resource allocation in lieu of 'taxes' and 'spending'.
