Available in PDF, EPUB and Kindle. Book excerpt: A fully expanded edition of the Nobel Prize–winning economist's classic book This collection of essays uses the lens of rational expectations theory to examine how governments anticipate and plan for inflation, and provides insight into the pioneering research for which Thomas Sargent was awarded the 2011 Nobel Prize in economics. Rational expectations theory is based on the simple premise that people will use all the information available to them in making economic decisions, yet applying the theory to macroeconomics and econometrics is technically demanding. Here, Sargent engages with practical problems in economics in a less formal, noneconometric way, demonstrating how rational expectations can satisfactorily interpret a range of historical and contemporary events. He focuses on periods of actual or threatened depreciation in the value of a nation's currency. Drawing on historical attempts to counter inflation, from the French Revolution and the aftermath of World War I to the economic policies of Margaret Thatcher and Ronald Reagan, Sargent finds that there is no purely monetary cure for inflation; rather, monetary and fiscal policies must be coordinated. This fully expanded edition of Rational Expectations and Inflation includes Sargent's 2011 Nobel lecture, "United States Then, Europe Now." It also features new articles on the macroeconomics of the French Revolution and government budget deficits.

Download or read book The Limits of Rationality written by Karen Schweers Cook and published by University of Chicago Press. This book was released on 1990-11-15 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prevailing economic theory presumes that agents act rationally when they make decisions, striving to maximize the efficient use of their resources. Psychology has repeatedly challenged the rational choice paradigm with persuasive evidence that people do not always make the optimal choice. Yet the paradigm has proven so successful a predictor that its use continues to flourish, fueled by debate across the social sciences over why it works so well. Intended to introduce novices to rational choice theory, this accessible, interdisciplinary book collects writings by leading researchers. The Limits of Rationality illuminates the rational choice paradigm of social and political behavior itself, identifies its limitations, clarifies the nature of current controversies, and offers suggestions for improving current models. In the first section of the book, contributors consider the theoretical foundations of rational choice. Models of rational choice play an important role in providing a standard of human action and the bases for constitutional design, but do they also succeed as explanatory models of behavior? Do empirical failures of these explanatory models constitute a telling condemnation of rational choice theory or do they open new avenues of investigation and theorizing? Emphasizing analyses of norms and institutions, the second and third sections of the book investigate areas in which rational choice theory might be extended in order to provide better models. The contributors evaluate the adequacy of analyses based on neoclassical economics, the potential contributions of game theory and cognitive science, and the consequences for the basic framework when unequal bargaining power and hierarchy are introduced.

Download or read book Inflation Expectations written by Peter J. N. Sinclair and published by Routledge. This book was released on 2009-12-16 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.

Download or read book The Social Sciences and Rationality written by Hudson Meadwell and published by Routledge. This book was released on 2017-10-19 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, rational choice theory has emerged as the single most powerful, controversial claimant to provide a unified, theoretical framework for all the social sciences. In its simplest form, the theory postulates that humans are purposive beings who pursue their goals in a rational, efficient manner, seeking the greatest benefit at the lowest cost. This volume brings together prominent scholars working in several social science disciplines and the philosophy of science to debate the promise and problems of rational choice theory. As rational choice theory has spread from its home base in economics to other disciplines, it has come under fierce criticism. To its critics, the extension of the explanatory model mistakenly assumes that the logic of economic rationality can explain non-economic behavior and, at its worst, commits the ethnocentric error of imposing Western concepts of rationality on non-Western societies and cultures. This volume includes strong advocates as well as forceful critics of the rational choice approach. However, in contrast to previous debates, all the contributors share a commitment to open, constructive and knowledgeable dialogue. Well-known advocates of rational choice theory (Michael Hechter, Michael Smith, Chris Manfredi) explicitly ponder some of its serious limitations, while equally well-known critics (Ian Shapiro, Mario Bunge) strike a surprisingly conciliatory tone in contemplating its legitimate uses. Vociferous critics of neoclassical economics (Bunge) favorably discuss sociological proponents of rational choice theory while two economists who are not particularly anti-mainstream (Robin Rowley, George Grantham) critically assess the problems of such assumptions in their discipline. Philosophers (Storrs McCall) and sociologists (John Hall) alike reflect on the variable meaning of rationality in explaining social behavior. In the introduction and conclusion, the editors survey the current state of the debate and show how open, constructive dialogue enables us to move beyond hackneyed accusations and dismissals that have characterized much previous debate.

Download or read book Rational Expectations Econometrics written by Lars Peter Hansen and published by CRC Press. This book was released on 2019-09-05 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the core of the rational expectations revolution is the insight that economic policy does not operate independently of economic agents' knowledge of that policy and their expectations of the effects of that policy. This means that there are very complicated feedback relationships existing between policy and the behaviour of economic agents, and these relationships pose very difficult problems in econometrics when one tries to exploit the rational expectations insight in formal economic modelling. This volume consists of work by two rational expectations pioneers dealing with the "nuts and bolts" problems of modelling the complications introduced by rational expectations. Each paper deals with aspects of the problem of making inferences about parameters of a dynamic economic model on the basis of time series observations. Each exploits restrictions on an econometric model imposed by the hypothesis that agents within the model have rational expectations.

Download or read book Learning and Expectations in Macroeconomics written by George W. Evans and published by Princeton University Press. This book was released on 2012-01-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crucial challenge for economists is figuring out how people interpret the world and form expectations that will likely influence their economic activity. Inflation, asset prices, exchange rates, investment, and consumption are just some of the economic variables that are largely explained by expectations. Here George Evans and Seppo Honkapohja bring new explanatory power to a variety of expectation formation models by focusing on the learning factor. Whereas the rational expectations paradigm offers the prevailing method to determining expectations, it assumes very theoretical knowledge on the part of economic actors. Evans and Honkapohja contribute to a growing body of research positing that households and firms learn by making forecasts using observed data, updating their forecast rules over time in response to errors. This book is the first systematic development of the new statistical learning approach. Depending on the particular economic structure, the economy may converge to a standard rational-expectations or a "rational bubble" solution, or exhibit persistent learning dynamics. The learning approach also provides tools to assess the importance of new models with expectational indeterminacy, in which expectations are an independent cause of macroeconomic fluctuations. Moreover, learning dynamics provide a theory for the evolution of expectations and selection between alternative equilibria, with implications for business cycles, asset price volatility, and policy. This book provides an authoritative treatment of this emerging field, developing the analytical techniques in detail and using them to synthesize and extend existing research.

Download or read book The Inflation Targeting Debate written by Ben S. Bernanke and published by University of Chicago Press. This book was released on 2007-11-01 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past fifteen years, a significant number of industrialized and middle-income countries have adopted inflation targeting as a framework for monetary policymaking. As the name suggests, in such inflation-targeting regimes, the central bank is responsible for achieving a publicly announced target for the inflation rate. While the objective of controlling inflation enjoys wide support among both academic experts and policymakers, and while the countries that have followed this model have generally experienced good macroeconomic outcomes, many important questions about inflation targeting remain. In Inflation Targeting, a distinguished group of contributors explores the many underexamined dimensions of inflation targeting—its potential, its successes, and its limitations—from both a theoretical and an empirical standpoint, and for both developed and emerging economies. The volume opens with a discussion of the optimal formulation of inflation-targeting policy and continues with a debate about the desirability of such a model for the United States. The concluding chapters discuss the special problems of inflation targeting in emerging markets, including the Czech Republic, Poland, and Hungary.

Download or read book Rational Machines and Artificial Intelligence written by Tshilidzi Marwala and published by Academic Press. This book was released on 2021-03-31 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intelligent machines are populating our social, economic and political spaces. These intelligent machines are powered by Artificial Intelligence technologies such as deep learning. They are used in decision making. One element of decision making is the issue of rationality. Regulations such as the General Data Protection Regulation (GDPR) require that decisions that are made by these intelligent machines are explainable. Rational Machines and Artificial Intelligence proposes that explainable decisions are good but the explanation must be rational to prevent these decisions from being challenged. Noted author Tshilidzi Marwala studies the concept of machine rationality and compares this to the rationality bounds prescribed by Nobel Laureate Herbert Simon and rationality bounds derived from the work of Nobel Laureates Richard Thaler and Daniel Kahneman. Rational Machines and Artificial Intelligence describes why machine rationality is flexibly bounded due to advances in technology. This effectively means that optimally designed machines are more rational than human beings. Readers will also learn whether machine rationality can be quantified and identify how this can be achieved. Furthermore, the author discusses whether machine rationality is subjective. Finally, the author examines whether a population of intelligent machines collectively make more rational decisions than individual machines. Examples in biomedical engineering, social sciences and the financial sectors are used to illustrate these concepts. Provides an introduction to the key questions and challenges surrounding Rational Machines, including, When do we rely on decisions made by intelligent machines? What do decisions made by intelligent machines mean? Are these decisions rational or fair? Can we quantify these decisions? and Is rationality subjective? Introduces for the first time the concept of rational opportunity costs and the concept of flexibly bounded rationality as a rationality of intelligent machines and the implications of these issues on the reliability of machine decisions Includes coverage of Rational Counterfactuals, group versus individual rationality, and rational markets Discusses the application of Moore’s Law and advancements in Artificial Intelligence, as well as developments in the area of data acquisition and analysis technologies and how they affect the boundaries of intelligent machine rationality

Download or read book The Conquest of American Inflation written by Thomas J. Sargent and published by Princeton University Press. This book was released on 1999 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Conquest of American Inflation, Thomas J. Sargent presents an analysis of the rise and fall of U.S. inflation after 1960. He examines two broad explanations for the behavior of inflation and unemployment in this period: the natural rate hypothesis joined to the Lucas critique and a more traditional econometric policy evaluation modified to include adaptive expectations and learning. His purpose is not only to determine which is the better account, but also to codify for the benefit of the next generation the economic forces that cause inflation. Providing an original methodological link between theoretical and policy economics, this book will engender much debate and become an indispensable text for academics, graduate students, and professional economists.

This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major controversies in macroeconomics over the last 30 years has been that on the effectiveness of stabilization policies. However, this debate, between those who believe that this kind of policies is useless if not harmful and those who argue in favor of it, has been mainly theoretical so far. The Rational Expectation Hypothesis, Time-Varying Parameters and Adaptive Control wants to represent a step toward the construction of a common ground on which to empirically compare the two "beliefs" and to do this three strands of literature are brought together. The first strand is the research on time-varying parameters (TVP), the second strand is the work on adaptive control and the third one is the literature on linear stationary models with rational expectations (RE). The material presented in The Rational Expectation Hypothesis, Time-Varying Parameters and Adaptive Control is divided into two parts. Part 1 combines the strand of literature on adaptive control with that on TVP. It generalizes the approach pioneered by Tse and Bar-Shalom (1973) and Kendrick (1981) and one recently used in Amman and Kendrick (2002), where the law of motion of the TVP and the hyperstructural parameters are assumed known, to the case where the hyperstructural parameters are assumed unknown. Part 2 is devoted to the linear single-equation stationary RE model estimated with the error-in-variables (EV) method. It presents a new formulation of this problem based on the use of TVP in an EV model. This new formulation opens the door to a very promising development. All the theory developed in the first part to control a model with TVP can sic et simpliciter be applied to control a model with RE.

Download or read book Imperfect Knowledge Economics written by Roman Frydman and published by Princeton University Press. This book was released on 2023-09-26 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Posing a major challenge to economic orthodoxy, Imperfect Knowledge Economics asserts that exact models of purposeful human behavior are beyond the reach of economic analysis. Roman Frydman and Michael Goldberg argue that the longstanding empirical failures of conventional economic models stem from their futile efforts to make exact predictions about the consequences of rational, self-interested behavior. Such predictions, based on mechanistic models of human behavior, disregard the importance of individual creativity and unforeseeable sociopolitical change. Scientific though these explanations may appear, they usually fail to predict how markets behave. And, the authors contend, recent behavioral models of the market are no less mechanistic than their conventional counterparts: they aim to generate exact predictions of "irrational" human behavior. Frydman and Goldberg offer a long-overdue response to the shortcomings of conventional economic models. Drawing attention to the inherent limits of economists' knowledge, they introduce a new approach to economic analysis: Imperfect Knowledge Economics (IKE). IKE rejects exact quantitative predictions of individual decisions and market outcomes in favor of mathematical models that generate only qualitative predictions of economic change. Using the foreign exchange market as a testing ground for IKE, this book sheds new light on exchange-rate and risk-premium movements, which have confounded conventional models for decades. Offering a fresh way to think about markets and representing a potential turning point in economics, Imperfect Knowledge Economics will be essential reading for economists, policymakers, and professional investors.

Download or read book Ambiguity no Arbitrage and the Limits to Rational Expectations written by Hendri Adriaens and published by . This book was released on 2008 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional finance approach combines the rational expectations hypothesis with the assumption of no arbitrage. However, the numerous anomalies reported in the finance literature reject this approach. The behavioral finance approach takes rational expectations as the maintained hypothesis with as null hypothesis no arbitrage versus the alternative of limits to arbitrage. Anomalies are interpreted as rejecting the null, suggesting that non-rational noise traders affect the outcomes in financial markets, explaining the anomalies. Alternatively, we take no arbitrage as maintained hypothesis and consider as null hypothesis rational expectations versus the alternative of expectations characterized by ambiguity. But also under ambiguity arbitrage opportunities will be exploited, making no arbitrage the relevant maintained hypothesis. Expectations are modeled as output of an econometric model. Ambiguity arises when the econometric model generates multiple probability distributions, for instance, when modeling a complicated, hard to fully understand financial market, possibly with unforeseen contingencies. Anomalies are then a violation of the null of rational expectations, implying that anomalies need not arise due to the presence of non-rational investors, but are just an artefact of imposing the possibly unrealistically strong assumption of rational expectations.
