Multiple Unemployment Equilibria Under Non-representative Agent Demand


Book Description

This dissertation analyzes the possibility that high unemployment can be be self-reinforcing through its effects on the distribution of income and, consequently, aggregate demand. The major results of my work demonstrate that these forces can lead to multiple macroeconomic equilibria which are indexed by the level of unemployment. By characterizing low output and employment states as equilibrium outcomes, this thesis provides a coherent theoretical explanation for periods of persistently high unemployment. The key property throughout is non-homotheticity of consumers' preferences, whereby the market demand for goods changes as income distribution changes, even if the total income of all consumers remains fixed. This implies that, unlike in many macroeconomic models, demand cannot be generated from a representative agent and, crucially, that changes in employment along the extensive, as opposed to intensive, margin can have more severe general equilibrium consequences.

Development Economics in the Twenty-First Century


Book Description

Development Economics has been identified as a homogeneous body of theory since the 1950s, concerned both with the study of development issues and with the shaping of more effective policies for less advanced economies. Development Economics in the Twenty-First Century brings together an international contributor team in order to explore the origins and evolution of development economics. This book highlights the different elements of ‘high development theory’ through a precise reconstruction of the different theoretical approaches that developed between the 1950s and the 1970s. These include the theory of balanced and unbalanced growth theory, the debate on international trade, the concept of dualism, dependency theory, structuralism and the analysis of poverty and institutions. The chapters highlight the relevance and usefulness of these analyses for the contemporary theoretical debate on development issues. Comparative perspectives are explored and analysed, including those of Keynes, Hirschman, Krugman and Stiglitz. The chapters situate development economics within current debates among economists and historians of economic thought, providing a platform for future research. This book is suitable for researchers and students with an interest in Development Economics, the History of Economic development and the Economics of Developing Countries.




What Every Economics Student Needs to Know and Doesn't Get in the Usual Principles Text


Book Description

This short book explores a core group of 40 topics that tend to go unexplored in an Introductory Economics course. Though not a replacement for an introductory text, the work is intended as a supplement to provoke further thought and discussion by juxtaposing blackboard models of the economy with empirical observations. Each chapter starts with a short "refresher" of standard neoclassical economic modelling before getting into real world economic life. Komlos shows how misleading it can be to mechanically apply the perfect competition model in an oligopolistic environment where only an insignificant share of economic activity takes place in perfectly competitive conditions. Most economics texts introduce the notion of oligopoly and differentiate it from the perfect competition model with its focus on "price takers." Komlos contends that oligopolies are "price makers" like monopolies and cause consumers and economies nearly as much harm. Likewise, most textbook authors eschew any distortions of market pricing by government, but there is usually little discussion of the real impact of minimum wages, which Komlos corrects. The book is an affordable supplement for all basic economics courses or for anyone who wants to review the basic ideas of economics with clear eyes.




Aggregation and the Microfoundations of Dynamic Macroeconomics


Book Description

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.




Handbook of Computable General Equilibrium Modeling


Book Description

In this collection of 17 articles, top scholars synthesize and analyze scholarship on this widely used tool of policy analysis, setting forth its accomplishments, difficulties, and means of implementation. Though CGE modeling does not play a prominent role in top US graduate schools, it is employed universally in the development of economic policy. This collection is particularly important because it presents a history of modeling applications and examines competing points of view. - Presents coherent summaries of CGE theories that inform major model types - Covers the construction of CGE databases, model solving, and computer-assisted interpretation of results - Shows how CGE modeling has made a contribution to economic policy




The New Generation of Computable General Equilibrium Models


Book Description

This book covers some important topics in the construction of computable general equilibrium (CGE) models and examines use of these models for the analysis of economic policies, their properties, and their implications. Readers will find explanation and discussion of the theoretical structure and practical application of several model typologies, including dynamic, stochastic, micro-macro, and simulation models, as well as different closure rules and policy experiments. The presentation of applications to various country and problem-specific case studies serves to provide an informed and clearly articulated summary of the state of the art and the most important methodological advancements in the field of policy modeling within the framework of general equilibrium analysis. The book is an outcome of a recent workshop of the Italian Development Economists Association attended by a group of leading practitioners involved in the generation of CGE models and research on modeling the economy and policy making. It will be of interest to researchers, professional economists, graduate students, and knowledgeable policy makers.

Financial Markets Theory


Book Description

This work, now in a thoroughly revised second edition, presents the economic foundations of financial markets theory from a mathematically rigorous standpoint and offers a self-contained critical discussion based on empirical results. It is the only textbook on the subject to include more than two hundred exercises, with detailed solutions to selected exercises. Financial Markets Theory covers classical asset pricing theory in great detail, including utility theory, equilibrium theory, portfolio selection, mean-variance portfolio theory, CAPM, CCAPM, APT, and the Modigliani-Miller theorem. Starting from an analysis of the empirical evidence on the theory, the authors provide a discussion of the relevant literature, pointing out the main advances in classical asset pricing theory and the new approaches designed to address asset pricing puzzles and open problems (e.g., behavioral finance). Later chapters in the book contain more advanced material, including on the role of information in financial markets, non-classical preferences, noise traders and market microstructure. This textbook is aimed at graduate students in mathematical finance and financial economics, but also serves as a useful reference for practitioners working in insurance, banking, investment funds and financial consultancy. Introducing necessary tools from microeconomic theory, this book is highly accessible and completely self-contained. Advance praise for the second edition: "Financial Markets Theory is comprehensive, rigorous, and yet highly accessible. With their second edition, Barucci and Fontana have set an even higher standard!"Darrell Duffie, Dean Witter Distinguished Professor of Finance, Graduate School of Business, Stanford University "This comprehensive book is a great self-contained source for studying most major theoretical aspects of financial economics. What makes the book particularly useful is that it provides a lot of intuition, detailed discussions of empirical implications, a very thorough survey of the related literature, and many completely solved exercises. The second edition covers more ground and provides many more proofs, and it will be a handy addition to the library of every student or researcher in the field."Jaksa Cvitanic, Richard N. Merkin Professor of Mathematical Finance, Caltech "The second edition of Financial Markets Theory by Barucci and Fontana is a superb achievement that knits together all aspects of modern finance theory, including financial markets microstructure, in a consistent and self-contained framework. Many exercises, together with their detailed solutions, make this book indispensable for serious students in finance."Michel Crouhy, Head of Research and Development, NATIXIS
