Описание: 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, demonstrat

The Evolving Rationality of Rational Expectations

Описание: Inspired by recent developments in science studies, this book offers an innovative type of analysis of the recent history of rational expectations economics. In the course of exploring the multiple dimensions of rational expectations analysis, Professor Sent focuses on the work of Thomas Sargent, an instrumental pioneer in the development of this school of thought. The investigation attempts to avoid a Whiggish history that sees Sargent’s development as inevitably progressing to better and better economic analysis. Instead, it provides an illustration of what happened to the approach through a contextualization of Sargent’s work vis-a-vis that of other scholars and ideas. The treatment aims to illuminate some of the shifting negotiations and alliances that characterize the rise and shift of direction in rational expectations economics. The Evolving Rationality of Rational Expectations won the 1998 Gunnar Myrdal Prize of the European Association for Evolutionary Political Economy for the best monograph on a theme broadly in accord with the EAEPE Theoretical Perspectives.

Описание: Olof DahlbГ¤ck's book breaks new ground for the analysis of crime from a rationality perspective by presenting models and methods that go far beyond those with which researchers have hitherto been equipped. The book examines single crimes, individual criminality, and societal crime, and it discusses thoroughly the general decision theoretical presuppositions necessary for analyzing these various types of crime. An expected utility maximization model for a single discrete choice regarding the commission of a crime is the foundation of most of the analyses presented. A version of this model is developed that permits interpersonal comparisons, and this basic model is used when deriving more complex models of crime as well as when analyzing the potential for such derivations. The rigorous, powerful methods suggested provide considerable opportunities for improving research and for seeing old problems in a new light.

The Rational Expectation Hypothesis, Time-Varying Parameters and Adaptive Control / A Promising Combination?

Описание: 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.

Описание: It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage argued that it would be ridiculous to use his theory outside the kind of small world. This book explains the foundations of this theory and shows why Savage restricted the theory`s application to small worlds.
