Economic space is the distance that separates economic agents such as manufacturers and consumers. Distance naturally imposes costs on the economic agents, but it has long been a neglected element in orthodox economic theory, one thought to complicate the issue unnecessarily. However, the theoretical implications of assuming away spatial elements may be especially significant for pricing practices and hence for competition. This volume shows why and in what ways the concept of economic space is vital and thus needed to reform orthodox price theory. It negates the classical paradigm of perfect competition and calls for a spatial price theory of imperfect competition. Among Hiroshi Ohta's findings in spatial microeconomic theory are that unlimited entry of new firms into the market may not lower consumer prices and that increased labor productivity in a spatial economy may actually lower real wages. Researchers and students of economic geography and regional science and economics will find the author's careful analysis, equations, and illustrations valuable in understanding a decade of advances in spatial price theory and in exploring new theories of competition.

This new approach to traditional price theory and to the analysis of imperfect competition represents a breakthrough in the development of a "new" microeconomic theory. Addresses issues in price theory, industrial organization, international trade and regional urban economics.

This collection of readings provides a broad overview of the major theoretical concepts in the field and includes papers on industry size, quantity and price competition, entry barriers, product differentiation, incomplete information and general equilibrium with imperfect competition.

New goods are at the heart of economic progress. The eleven essays in this volume include historical treatments of new goods and their diffusion; practical exercises in measurement addressed to recent and ongoing innovations; and real-world methods of devising quantitative adjustments for quality change. The lead article in Part I contains a striking analysis of the history of light over two millenia. Other essays in Part I develop new price indexes for automobiles back to 1906; trace the role of the air conditioner in the development of the American south; and treat the germ theory of disease as an economic innovation. In Part II essays measure the economic impact of more recent innovations, including anti-ulcer drugs, new breakfast cereals, and computers. Part III explores methods and defects in the treatment of quality change in the official price data of the United States, Canada, and Japan. This pathbreaking volume will interest anyone who studies economic growth, productivity, and the American standard of living.

"The discrete choice approach provides an ideal framework for describing the demands for differentiated products and can be used for studying most product differentiation models in the literature. By introducing extra dimensions of product heterogeneity, the framework also provides richer models of firm location and product selection."--BOOK JACKET.

Avinash Dixit and Joseph Stiglitz revolutionized the modelling of imperfectly competitive markets and launched "the second monopolistic competition revolution". Experts in the areas of macroeconomics, international trade theory, economic geography, and international growth theory examine the success of the second revolution in this collection of papers. They reveal what appears to be "missing" and look forward to the next step in the modelling of imperfectly competitive markets. The text includes a comprehensive survey of the two monopolistic competition revolutions, and previously unpublished working papers by Dixit and Stiglitz that led to their famous 1977 paper.

Since the publication of the first edition of Network Economics: A Variational Inequality Approach in 1993, there have been many ad vances in both methodological developments, as well as, applications in this field. These have occurred in an environment of an increasingly networked global economy, in which the importance of transportation networks and communication networks is now well-recognized, with net works such as knowledge networks, environmental networks, and finan cial networks receiving growing attention. This edition adds recent research progress in new and evolving ar eas of network economics through common and unifying principles. In addition, it includes dynamic models of traffic, of spatially separated markets, of oligopolistic markets, and of financial markets. In order to expand the range and reach of this material, we have also included a series of problems in an appendix for self-study purposes and for use in the classroom. We note that computational economics has been at the forefront in stimulating the development of mathematical methodologies for the analysis and solution of complex, large-scale problems. The past fifteen years, in particular, have witnessed a dramatic growth of interest in this area. Supported by the increasing availability of data and by advances in computer architectures, the scale and dimensions of problems that can now be handled are unveiling new horizons in both theoretical modeling and policy analysis.

This book provides the first unifying treatment of the range of economic reasons for the clustering of firms and households. Its goal is to explain further the trade-off between various forms of increasing returns and different types of mobility costs. Although referring to agglomeration as a generic term is convenient, it should be noted that the concept of economic agglomeration refers to distinct real world situations. The main focus of the treatment is on cities, but it also explores the formation of agglomerations, such as commercial districts within cities, industrial clusters at the regional level, and the existence of imbalance between regions. The book is rooted within the realm of modern economics and borrows concepts from geography and regional science, which makes it accessible to a broad audience formed by economists, geographers, regional planners, and other scientists. It may be used in coursework for graduate students and upper-level undergraduates.

These contributions discuss a number of important developments over the past decade in a newly established and important field of economics that have led to notable changes in views on governmental competition policies. They focus on the nature and role of competition and other determinants of market structures, such as numbers of firms and barriers to entry; other factors which determine the effective degree of competition in the market; the influence of major firms (especially when these pursue objectives other than profit maximization); and decentralization and coordination under control relationships other than markets and hierarchies.ContributorsJoseph E.
