This volume links a microeconomic model of imperfectly informed firms and unions in monopolistic competition to a general theory of wage- and price-setting in a macroeconomic model. The analysis is based on a profit maximization and rational behaviour and is thus in line with the newly emerged New Keynesian approach in its emphasis on the microeconomic foundation of macroeconomics. The volume goes on to explain three stylized facts in macroeconomics: nominal rigidity, real rigidity, and cost-oriented prices, presented in a coherent New Keynesian framework. The analysis also provides new insight into the role of competition in an economy with imperfectly and differentially informed firms. It shows that increased competition may increase nominal as well as real price rigidity and increased volatility of investment.
Through careful methodological analysis, this book argues that modern macroeconomics has completely overlooked the aggregate nature of the data. In Part I, the authors test and reject the homogeneity assumption using disaggregate data. In Part II, they demonstrate that apart from random flukes, cointegration unidirectional Granger causality and restrictions on parameters do not survive aggregation when heterogeneity is introduced. They conclude that the claim that modern macroeconomics has solid microfoundations is unwarranted. However, some important theory-based models that do not fit aggregate data well in their representative-agent version can be reconciled with aggregate data by introducing heterogeneity.
This graduate textbook is a "primer" in macroeconomics. It starts with essential undergraduate macroeconomics and develops in a simple and rigorous manner the central topics of modern macroeconomic theory including rational expectations, growth, business cycles, money, unemployment, government policy, and the macroeconomics of nonclearing markets. The emphasis throughout the book is on both foundations and presenting the simplest model for each topic that will deliver the relevant answers. The first two chapters recall the main workhorses of undergraduate macroeconomics: the Solow-Swan growth model, the Keynesian IS-LM model, and the Phillips curve. The next chapters present four fundamental "building blocks" of modern macroeconomics: rational expectations, intertemporal dynamic models, nonclearing markets and imperfect competition, and uncertainty. Later the book deals with growth, notably the Ramsey model, overlapping generations, and endogenous growth. Chapter 10 moves to the famous "real business cycles" (RBC), which integrate in a unified framework growth and fluctuations. The final chapters look at the issue of stabilization, how best to guard the economy from shocks, and the connections between politics and the macroeconomy. To make the book self contained, a mathematical appendix gives a number of simple technical results that are sufficient to follow the formal developments of the book.
Unemployment, Recession and Effective Demand is a fine example of how critical analysis and debate about fundamental issues should be carried on. Claudio Sardoni does not pull his punches, but he criticises with courtesy in a learned and fair-minded way. His writings are a role model of proper procedure allied with cumulative persuasion through weight of evidence, sound scholarship and argument.' - From the foreword by G.C. Harcourt In the midst of the current world economic crisis, many claim there is a necessity to return to the Marxian and Keynesian traditions in order to better understand the dynamics of market economies. This book is an important step in that direction. It presents a critical examination of the foundations of macroeconomics as developed in the traditions of Marx, Keynes and Kalecki, which are contrasted with the current mainstream. Particular attention is given to the problem of market forms and their relevance for macroeconomics. Professional economists and postgraduate students in economics, in particular those concerned with macroeconomics and the history of economic thought in the 20th century, will find this insightful resource invaluable. This book should be required reading for a large proportion of the economics profession who are dissatisfied with the mainstream.
The macroeconomics of imperect competition has become in recent years a most influential paradigm, which many macroeconomists now prefer to the Classical of Keynesian ones, notably because of its clear and rigorous microfoundations. This volume collects and puts into perspective the leading contributions to this important and rapidly expanding field.
Given that there is no shortage of economic theories while economic problems are growing periodically, Conceptual Economics boldly attempts to initiate a new approach by employing conceptual and intuitive tools to examine the intra-relationship between microeconomics and macroeconomics as well as the inter-relationship between economic analysis and other social science studies, especially the relationship with political science. The few intuitive ideas include the separation between ex-ante situations and ex-post outcomes, the difference between endowment differences and unequal outcomes, and the role of economics as a vehicle in the delivery of numerous social and political activities. The discussion extends to cover an analysis on human values and concludes with a recommendation on the functionality of civic capitalism. With intuition and analytical reasoning within economics and with other social sciences, Conceptual Economics can become a new branch in economic study where scholars, analysts and intellectuals could 'think outside the box' by liaising a wider economic perspective and/or amalgamating non-economic aspects into their analysis. This shall provide a new dimension to solving human economic problems and possibly area of intellectuality.
Several years have passed since the 'store wars' over barriers to foreign products at Japanese distribution firms. Yet among English-speaking readers, how these firms operate remains a puzzle. In this book, the best Japanese scholars in their fields attempt to unravel that puzzle. Avoiding culture-based explanations, they employ a systematic and rigorous economic logic---yet, since they also avoid mathematical notation, the argument remains accessible to generalist readers.
