The idea of duality has proved to be a powerful device in modern work on the economics of consumer behaviour. The authors have used duality to provide an integrated and accessible treatment of this subject. The book focuses on applications of the theory to welfare economics and econometric analysis. The book begins with four chapters that provide a self-contained presentation of the basic theory and its use in applied econometrics. These chapters also include elementary extensions of the theory to labour supply, durable goods, the consumption function, and rationing. The rest of the book is divided into three parts. In the first of these the authors discuss restrictions on choice and aggregation problems. The next part consists of chapters on consumer index numbers; household characteristics, demand, and household welfare comparisons; and social welfare and inequality. The last part extends the coverage of consumer behaviour to include the quality of goods and household production theory, labour supply and human capital theory, the consumption function and intertemporal choice, the demand for durable goods, and choice under uncertainty.

Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.

This book examines why game theory has become such a popular tool of analysis. It investigates the deficiencies in this methodology and goes on to consider whether its popularity will fade or remain an important tool for economists. The book provides the reader with some basic concepts from noncooperative theory, and then goes on to explore the strengths, weaknesses, and future of the theory as a tool of economic modelling and analysis. All those interested in the applications of game theory to economics, from undergraduates to academics will find this study of particular value.

Macro Markets puts forward a unique and authoritative set of detailed proposals for establishing new markets for the management of the biggest economic risks facing society. Our existing financial markets are seen as being inadequate in dealing with such risks and Professor Shiller suggests major new markets as solutions to the problem. Shiller argues that although some risks, such as natural disaster or temporary unemployment, are shared by society, most risks are borne by the individual and standards of living determined by luck. He investigates whether a new technology of markets could make risk-sharing possible, and shows how new contracts could be designed to hedge all manner of risks to the individual's living standards. He proposes new international markets for perpetual claims on national incomes, and on components and aggregates of national incomes, concluding that these markets may well dwarf our stock markets in their activity and significance. He also argues for new liquid international markets for residential and commercial property. Establishing such unprecedented new markets presents some important technical problems which Shiller attempts to solve with proposals for implementing futures markets on perpetual claims on incomes, and for the construction of index numbers for cash settlement of risk management contracts. These new markets could fundamentally alter and diminish international economic fluctuations, and reduce the inequality of incomes around the world.

Income Distribution In Macroeconomic Models

This book looks at the distribution of income and wealth and the effects that this has on the macroeconomy, and vice versa. Is a more equal distribution of income beneficial or harmful for macroeconomic growth, and how does the distribution of wealth evolve in a market economy? Taking stock of results and methods developed in the context of the 1990s revival of growth theory, the authors focus on capital accumulation and long-run growth. They show how rigorous, optimization-based technical tools can be applied, beyond the representative-agent framework of analysis, to account for realistic market imperfections and for political-economic interactions. The treatment is thorough, yet accessible to students and nonspecialist economists, and it offers specialist readers a wide-ranging and innovative treatment of an increasingly important research field. The book follows a single analytical thread through a series of different growth models, allowing readers to appreciate their structure and crucial assumptions. This is particularly useful at a time when the literature on income distribution and growth has developed quickly and in several different directions, becoming difficult to overview.

While the theoretical development of DSGE models is not overly difficult to understand, practical application remains somewhat complex. The literature on this subject has some significant obscure points. This book can be thought of, firstly, as a tool to overcome initial hurdles with this type of modeling. Secondly, by showcasing concrete applications, it aims to persuade incipient researchers to work with this methodology. In principle, this is not a book on macroeconomics in itself, but on tools used in the construction of this sort of models. It strives to present this technique in a detailed manner, thereby providing a step by step course intended to walk readers through this otherwise daunting process. The book begins with a basic Real Business Cycle model. Subsequently various frictions are gradually incorporated into a standard DSGE model: imperfect competition; frictions in prices and in wages ; habit formation; non-Ricardian agents; adjustment cost in investment; costs of not using the maximum installed capacity; and finally, Government.

This book provides a framework for thinking about economic instiutions such as firms. The basic idea is that institutions arise in situations where people write incomplete contracts and where the allocation of power or control is therefore important. Power and control are not standard concepts in economic theory. The book begins by pointing out that traditional approaches cannot explain on the one hand why all transactions do not take place in one huge firm and on the other hand why firms matter at all. An incomplete contracting or property rights approach is then developed. It is argued that this approach can throw light on the boundaries of firms and on the meaning of asset ownership. In the remainder of the book, incomplete contacting ideas are applied to understand firms' financial decisions, in particular, the nature of debt and equity (why equity has votes and creditors have foreclosure rights); the capital structure decisions of public companies; optimal bankruptcy procedure; and the allocation of voting rights across a company's shares. The book is written in a fairly non-technical style and includes many examples. It is aimed at advanced undergraduate and graduate students, academic and business economists, and lawyers as well as those with an interest in corporate finance, privatization and regulation, and transitional issues in Eastern Europe, the former Soviet Union, and China. Little background knowledge is required, since the concepts are developed as the book progresses and the existing literature is fully reviewed.
