Dynamic Macroeconomic Theory

The tasks of macroeconomics are to interpret observations on economic aggregates in terms of the motivations and constraints of economic agents and to predict the consequences of alternative hypothetical ways of administering government economic policy. General equilibrium models form a convenient context for analyzing such alternative government policies. In the past ten years, the strengths of general equilibrium models and the corresponding deficiencies of Keynesian and monetarist models of the 1960s have induced macroeconomists to begin applying general equilibrium models. This book describes some general equilibrium models that are dynamic, that have been built to help interpret time-series of observations of economic aggregates and to predict the consequences of alternative government interventions. The first part of the book describes dynamic programming, search theory, and real dynamic capital pricing models. Among the applications are stochastic optimal growth models, matching models, arbitrage pricing theories, and theories of interest rates, stock prices, and options. The remaining parts of the book are devoted to issues in monetary theory; currency-in-utility-function models, cash-in-advance models, Townsend turnpike models, and overlapping generations models are all used to study a set of common issues. By putting these models to work on concrete problems in exercises offered throughout the text, Sargent provides insights into the strengths and weaknesses of these models of money. An appendix on functional analysis shows the unity that underlies the mathematics used in disparate areas of rational expectations economics. This book on dynamic equilibrium macroeconomics is suitable for graduate-level courses; a companion book, Exercises in Dynamic Macroeconomic Theory, provides answers to the exercises and is also available from Harvard University Press.

Exercises in Dynamic Macroeconomic Theory

This book is a companion volume to Dynamic Macroeconomic Theory by Thomas J. Sargent. It provides scrimmages in dynamic macroeconomic theory--precisely the kind of drills that people will need in order to learn the techniques of dynamic programming and its applications to economics. By doing these exercises, the reader can acquire the ability to put the theory to work in a variety of new situations, build technical skill, gain experience in fruitful ways of setting up problems, and learn to distinguish cases in which problems are well posed from cases in which they are not. The basic framework provided by variants of a dynamic general equilibrium model is used to analyze problems in macroeconomics and monetary economics. An equilibrium model provides a mapping from parameters of preferences, technologies, endowments, and rules of the game to a probability model for time series. The rigor of the logical connections between theory and observations that the mapping provides is an attractive feature of dynamic equilibrium, or rational expectations, models. This book gives repeated and varied practice in constructing and interpreting this mapping.

Introduction to Dynamic Macroeconomic Theory

Economies are constantly in flux, and economists have long sought reliable means of analyzing their dynamic properties. This book provides a succinct and accessible exposition of modern dynamic (or intertemporal) macroeconomics. The authors use a microeconomics-based general equilibrium framework, specifically the overlapping generations model, which assumes that in every period there are two generations which overlap. This model allows the authors to fully describe economies over time and to employ traditional welfare analysis to judge the effects of various policies. By choosing to keep the mathematical level simple and to use the same modeling framework throughout, the authors are able to address many subtle economic issues. They analyze savings, social security systems, the determination of interest rates and asset prices for different types of assets, Ricardian equivalence, business cycles, chaos theory, investment, growth, and a variety of monetary phenomena. Introduction to Dynamic Macroeconomic Theory will become a classic of economic exposition and a standard teaching and reference tool for intertemporal macroeconomics and the overlapping generations model. The writing is exceptionally clear. Each result is illustrated with analytical derivations, graphically, and by worked out examples. Exercises, which are strategically placed, are an integral part of the book.

Macroeconomic Theory

Macroeconomic Theory is the most up-to-date graduate-level macroeconomics textbook available today. This book truly offers something new by emphasizing the general equilibrium character of macroeconomics to explain effects across the whole economy, not just part. It is also the perfect resource for economists who need to brush up on the latest developments. Michael Wickens lays out the core ideas of modern macroeconomics and its links with finance. He presents the simplest general equilibrium macroeconomic model for a closed economy, and then gradually develops a comprehensive model of the open economy. Every important topic is covered, including growth, business cycles, fiscal policy, taxation and debt finance, current account sustainability, exchange-rate determination, and an up-to-date account of monetary policy through inflation targeting. Wickens addresses the interrelationships between macroeconomics and modern finance and shows how they affect stock, bond, and foreign-exchange markets. While the mathematics needed for this book is rigorous, the author describes fundamental concepts in a way that helps make the book self-contained and easy to use. Accessible, comprehensive, and wide-ranging, Macroeconomic Theory will become the standard text for students and is ideal for economists, particularly those in government, central and commercial banking, and financial investment.

Recursive Macroeconomic Theory fourth edition

This fourth edition features two new chapters and substantial revisions to other chapters that demonstrate the power of recursive methods.

Recursive Macroeconomic Theory  fourth edition

The substantially revised fourth edition of a widely used text, offering both an introduction to recursive methods and advanced material, mixing tools and sample applications. Recursive methods provide powerful ways to pose and solve problems in dynamic macroeconomics. Recursive Macroeconomic Theory offers both an introduction to recursive methods and more advanced material. Only practice in solving diverse problems fully conveys the advantages of the recursive approach, so the book provides many applications. This fourth edition features two new chapters and substantial revisions to other chapters that demonstrate the power of recursive methods. One new chapter applies the recursive approach to Ramsey taxation and sharply characterizes the time inconsistency of optimal policies. These insights are used in other chapters to simplify recursive formulations of Ramsey plans and credible government policies. The second new chapter explores the mechanics of matching models and identifies a common channel through which productivity shocks are magnified across a variety of matching models. Other chapters have been extended and refined. For example, there is new material on heterogeneous beliefs in both complete and incomplete markets models; and there is a deeper account of forces that shape aggregate labor supply elasticities in lifecycle models. The book is suitable for first- and second-year graduate courses in macroeconomics. Most chapters conclude with exercises; many exercises and examples use Matlab or Python computer programming languages.

Stochastic Dynamic Macroeconomics

This is a book on stochastic dynamic macroeconomics from a Keynesian perspective. It shows that including Keynesian features in intertemporal models considerably contributes to resolve major puzzles arising in the context of the Dynamic General Equilibrium (DGE) model. It also demonstrates that including microeconomic intertemporal behavior of economic agents in macroeconomics is not inconsistent with Keynesian economics.

The Dynamic Macroeconomic Effects of Public Capital

This book analyzes the dynamic macroeconomic effects of public capital in industrialized countries.

The Dynamic Macroeconomic Effects of Public Capital

This book analyzes the dynamic macroeconomic effects of public capital in industrialized countries. The issue of whether public capital is productive has received a great deal of recent attention. Yet, existing empirical analyses have been limited to a small set of countries. This book presents a new database that provides internationally comparable capital stock estimates for 22 OECD countries for the 1960-2001 period. Building on this database, the book estimates the dynamic effects of public capital using a variety of econometric methods. The results suggest that public capital is productive in OECD countries on average. The theoretical analysis based on a dynamic general equilibrium model shows that the effects of public capital depend crucially on the way the government chooses to finance additional spending.

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.

Macroeconomic Theory

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.
