A Critical Assessment of the Role of Imperfect Competition in Macroeconomics


Book Description

New Keynesian models and some models of growth rely on market power for their results. This sole focus on market power as the source for certain macroeconomic phenomena is misguided both theoretically and empirically. New Keynesian multipliers are closely related to standard measures of deadweight loss used in the public finance literature. The theoretical analysis shows that a standard competitive model with taxes exactly reproduces the multipliers in the new Keynesian models, and the empirical evidence strongly suggests that taxes, not market power, will be the far more important influence on explaining short-run fluctuations in GNP. Theory and the empirical evidence suggest that the existence of intellectual property rights is likely to be a more important determinant of innovation than market power. Finally, the paper shows how models that incorporate the cost of market making, durability and dynamic policies, and timing based on the option value of resolving uncertainty can yield more valuable insights into macroeconomic phenomena than can models with market power.







Trade Policy Issues and Empirical Analysis


Book Description

Interest in U.S. trade policy has been stimulated in recent years by the massive American trade deficit, by the belief that intervention by foreign governments in international markets has given other countries a competitive edge over the United States, and by concern about the increase in protectionism among industrial countries. In turn, major analytical developments in international economics have revolutionized trade theory, broadening its scope both by introducing in a more formal manner such concepts as imperfect competition, increasing returns, product differentiation, and learning effects and by including the study of political and economic factors that shape trade policy decisions. This collection of papers—the result of a conference held by the NBER—applies these "new" trade theories to existing world cases and also presents complementary empirical studies that are grounded in more traditional trade theories. The volume is divided into four parts. The papers in part 1 consider the problem of imperfect competition, empirically assessing the economic effect of various trade policies introduced in industries in which the "new" trade theory seems to apply. Those in part 2 isolate the effects of protection from the influences of the many economic changes that accompany actual periods of protection and also examine how the effects from exogenous changes in economic conditions vary with the form of protection. Part 3 provides new empirical evidence on the effect of foreign production by a country's firms on the home country's exports. Finally, in part 4, two key bilateral issues are analyzed: recent U.S.-Japanese trade tensions and the incident involving the threat of the imposition of countervailing duties by the United States on Canadian softwood lumber.




Allocation, Information and Markets


Book Description

This is an extract from the 4-volume dictionary of economics, a reference book which aims to define the subject of economics today. 1300 subject entries in the complete work cover the broad themes of economic theory. This volume concentrates on the topic of allocation information and markets.




Monopolistic Competition and Macroeconomic Theory


Book Description

Much of today's conventional macroeconomic theory presumes that markets for goods approach the state of perfect competition. Monopolistic Competition and Macroeconomic Theory assumes that markets are imperfect, so that sellers have some power over price, and must therefore form quantity expectations about the location of the firm's demand curve. The question is then about the macroeconomic implications of imperfect competition in goods markets. The first chapter is a brief survey of ideas proposed in economics including multiple equilibria. The second chapter describes a particular micro-based macro model that allows several families of equilibria. The third chapter shows how a standard locational model can be used to describe a sample macroeconomy when firms have close rivals. In this volume derived from his Federico Caffe Lecture, Nobel Laureate Robert Solow shows that there are simple and tractable micro-based models that offer the possibility of a richer and more intuitive macroeconomics.




The Economics of New Goods


Book Description

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 Economics of Imperfect Competition


Book Description

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.

Market Behaviour and Macroeconomic Modelling


Book Description

Market Behaviour and Macroeconomic Modelling discusses several state-of-the-art developments in the modelling approach to market behaviour in macroeconomic modelling. Leading experts in this field, deal with the implications of market imperfections in commodity markets, capital markets and labour markets for macroeconomic modelling and stabilization policy. They demonstrate that incorporating market imperfections leads to very different policy recommendations than those derived from the standard perfect competition model.
