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.




Transforming Modern Macroeconomics


Book Description

Since the 1950s, macroeconomics has been transformed. This book is about one of the most important aspects of that transformation: the attempt, through the end of the twenty-first century and beyond, to construct macroeconomic models rigorously derived from models of individual firms and households.




Microfoundations Reconsidered


Book Description

Most macroeconomists agree that we live in the age of microfoundations. The recent worldwide financial crisis may have emboldened critics of this microfoundational orthodoxy, but it remains the dominant view that macroeconomic models must go beyond supply and demand functions to the level of individual decision-making, taking into account the general dynamic environment where agents live. Microfoundations Reconsidered seeks to reassess how the relationship of micro and macroeconomics evolved over time. The highly regarded contributors to the book argue that the standard narrative of microfoundations is likely to be unreliable. They therefore re-examine the history of the relationship of microeconomics and macroeconomics, starting from their emergence as self-consciously distinct fields within economics in the early 1930s. They seek to go beyond the conventional history that is often told and written by practicing economists. From different perspectives they challenge the association of microfoundations with Robert Lucas and rational expectations and offer both a more complete and a deeper reading of the relationship between micro and macroeconomics. Microfoundations Reconsidered is a valuable addition to the macroeconomic research literature. It is ideally suited to students, scholars, researchers, and practitioners with an interest in macro and microeconomics and the history of economics.




Microfoundations


Book Description

The first full-length survey of current work which examines the compatibility of microeconomics and macroeconomics.




Microfoundations of Financial Economics


Book Description

This textbook takes the reader from the level of microeconomics principles through to modern asset pricing theory. Yvan Lengwiler elegantly links together issues that have in the past been the territory of general economic theorists on the one hand, and financial economists on the other. In a sequence of carefully explained steps, the reader learns how the first welfare theorem is used in asset pricing theory. The book then moves on to explore Radner economies and von Neumann-Morgenstern decision theory, and this section culminates in Wilson's mutuality principle and the consumption-based CAPM. This is then put into a dynamic setting, and term structure models are introduced. The empirical shortcomings of the standard asset pricing models are extensively discussed, as is research from the last twenty years aimed at bringing theory in line with reality. The reader is brought up to date on the latest areas of concern, such as habit formation, the consequences of heterogeneity, demographic effects, changing tax regimes, market frictions, and the implications of prospect theory for asset pricing. Aimed at masters or Ph.D. students specializing in financial economics, the book can also be used as a supplementary text for students of macroeconomics at this advanced level and will be of interest to finance professionals with a background in economics and mathematics. It includes problems (with solutions), and an accompanying website provides supporting material for lecturers.




Advanced Modern Macroeconomics


Book Description

Modern Macroeconomics, by Max Gillman, takes a new and modern approach to macroeconomic theory using microeconomic foundations. Building from the standard neo-classical models, Gillman has developed a new dynamic model which works to explain business cycles and unemployment, why you can have a banking lead recession as well as fiscal and monetary policy. Although strong in mathematical rigour all calculations in this text are fully derived and graphs provide a direct representation making it accessible. This text is suitable for undergraduate students studying Advanced Macroeconomics courses.




The Macroeconomics of Self-fulfilling Prophecies


Book Description

Farmer argues for the future of macroeconomics as a branch ofapplied general equilibrium theory. His main theme is thatmacroeconomics is best viewed as the study of equilibrium environmentsin which the welfare theorems break down.




Recursive Methods in Economic Dynamics


Book Description

This rigorous but brilliantly lucid book presents a self-contained treatment of modern economic dynamics. Stokey, Lucas, and Prescott develop the basic methods of recursive analysis and illustrate the many areas where they can usefully be applied.




Foundations of International Macroeconomics


Book Description

Foundations of International Macroeconomics is an innovative text that offers the first integrative modern treatment of the core issues in open economy macroeconomics and finance. With its clear and accessible style, it is suitable for first-year graduate macroeconomics courses as well as graduate courses in international macroeconomics and finance. Each chapter incorporates an extensive and eclectic array of empirical evidence. For the beginning student, these examples provide motivation and aid in understanding the practical value of the economic models developed. For advanced researchers, they highlight key insights and conundrums in the field. Topic coverage includes intertemporal consumption and investment theory, government spending and budget deficits, finance theory and asset pricing, the implications of (and problems inherent in) international capital market integration, growth, inflation and seignorage, policy credibility, real and nominal exchange rate determination, and many interesting special topics such as speculative attacks, target exchange rate zones, and parallels between immigration and capital mobility. Most main results are derived both for the small country and world economy cases. The first seven chapters cover models of the real economy, while the final three chapters incorporate the economy's monetary side, including an innovative approach to bridging the usual chasm between real and monetary models.




Big Ideas in Macroeconomics


Book Description

An accessible description of modern macroeconomics, and a defense of its policy relevance. Macroeconomists have been caricatured either as credulous savants in love with the beauty of their mathematical models or as free-market fundamentalists who admit no doubt as to the market's wisdom. In this book, Kartik Athreya draws a truer picture, offering a nontechnical description of prominent ideas and models in macroeconomics, and arguing for their value as interpretive tools as well as their policy relevance. Athreya deliberately leaves out the technical machinery, providing an essential guide to the sometimes abstract ideas that drive macroeconomists' research and practical policy advice. Athreya describes the main approach to macroeconomic model construction, the foundational Walrasian general-equilibrium framework, and its modern version, the Arrow-Debreu-McKenzie (ADM) model. In the heart of the book, Athreya shows how the Walrasian approach shapes and unifies much of modern macroeconomics. He details models central to ongoing macroeconomic analyses: the neoclassical and stochastic growth models, the standard incomplete-markets model, the overlapping-generations model, and the standard search model. Athreya's accessible primer traces the links between the views and policy advice of modern macroeconomists and their shared theoretical approach.
