Search Theory And Unemployment

Search Theory and Unemployment contains nine chapters that survey and extend the theory of job search and its application to the problem of unemployment. The volume ranges from surveys of job search theory that take microeconomic and macroeconomic perspectives to original theoretical contributions which focus on the externalities arising from non-sequential search and search under imperfect information. It includes a clear and authoritative survey of econometric methods that have been developed to estimate models of job search, as well as two lucid contributions to the empirical search literature. Finally, it includes a study that reviews and extends the literature on optimal unemployment insurance and concludes with an appraisal of the influence of search theory on the thinking of macroeconomic policymakers.

The economics of search is a prominent component of economic theory, and it has a richness and elegance that underpins a host of practical applications. In this book Brian and John McCall present a comprehensive overview of the economic theory of search, from the classical model of job search formulated 40 years ago to the recent developments in equilibrium models of search. The book gives decision-theoretic foundations to seemingly slippery issues in labour market theory, estimation theory and economic dynamics in general, and surveys the entire field of the economics of search, including its history, theory, and econometric applications. Theoretical models of the economics of search are covered as well as estimation methods used in search theory and topics covered include job search, turnover, unemployment, liquidity, house selling, real options and auctions. The mathematical methods used in search theory such as dynamic programming are reviewed as well as structural estimation methods and econometric methods for duration models. The authors also explore the classic sequential search model and its extensions in addition to recent advances in equilibrium search theory.

This collection of papers marks the development of empirical application of the search approach to labor economics--an approach which arose as a theoretical development of the 1960s and led to numerous insights in the 1970s. The search approach naturally incorporates uncertainty in the economic model, making up some of the early work in what is now called "the economics of information." Included are econometric issues such as estimation and specification of search models for wages and unemployment duration, continuous time models of turnover, and identification of structural parameters. Applications to policy questions including Unemployment Insurance and wage subsidy programs are given, and data collection issues are discussed within the search framework.

A collection of papers which analyzes and measures unemployment as a search activity, discusses efficiency wage models and which considers the impact of government and unions on employment and unemployment.

The behavior of unemploy. over the bus. cycle plays an important role in economic policy considerations. Most of the variation in unemploy. comes about through changes in job-finding rates. Search theories of unemploy. study the implications of the matching process between unemployed workers and vacant jobs in environments with search frictions. The authors review work on whether these theories are consistent with the cyclical behavior of unemploy. and job-finding rates. They conclude that when the basic search model is calibrated to generate labor market volatility of a magnitude comparable with the data, it has sharp counterfactual implications for the size and the cyclicality of the wage share and for the elasticity of unemploy. to welfare benefits.

This volume defines the economics of search, which has become a part of the standard graduate curriculum. The concept deals with the costs and benefits to individual workers - either employed or unemployed - of seeking a job with the highest possible pay.

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.

Since the beginning of the economic crisis of the 1980s considerable research has been dedicated to the study of the unemployment problem. Nevertheless, the phenomenon has not become fully understood, nor are its consequences adequately prevented. In this important new volume, On the Mysteries of Unemployment, economists and social scientists come together to offer the reader the latest insights on unemployment and policies regarding unemployment from the perspectives of both disciplines. On the Mysteries of Unemployment contains four main sections. Part One provides an introductory chapter and general overview. Part Two contains rich contributions that provide new insights from an economic science perspective, while Part Three offers a balanced view from social scientists. The final section is devoted to the examination of policy issues concerning unemployment. This volume, unique in its field, will be of interest to researchers, students, politicians and policy-makers.
