Labor Markets and Business Cycles integrates search and matching theory with the neoclassical growth model to better understand labor market outcomes. Robert Shimer shows analytically and quantitatively that rigid wages are important for explaining the volatile behavior of the unemployment rate in business cycles. The book focuses on the labor wedge that arises when the marginal rate of substitution between consumption and leisure does not equal the marginal product of labor. According to competitive models of the labor market, the labor wedge should be constant and equal to the labor income tax rate. But in U.S. data, the wedge is strongly countercyclical, making it seem as if recessions are periods when workers are dissuaded from working and firms are dissuaded from hiring because of an increase in the labor income tax rate. When job searches are time consuming and wages are flexible, search frictions--the cost of a job search--act like labor adjustment costs, further exacerbating inconsistencies between the competitive model and data. The book shows that wage rigidities can reconcile the search model with the data, providing a quantitatively more accurate depiction of labor markets, consumption, and investment dynamics. Developing detailed search and matching models, Labor Markets and Business Cycles will be the main reference for those interested in the intersection of labor market dynamics and business cycle research.

Doing Business in 2005: Obstacles to Growth is the second in a series of annual reports investigating the scope and manner of regulations that enhance business activity and those that constrain it. New quantitative indicators on business regulations and their enforcement can be compared across more than 130 countries, and over time. The indicators are used to analyze economic outcomes and identify what reforms have worked, where and why. Topics in Doing Business in 2005 include: Licensing and Inspections: Having registered a business, now what? In most countries, firms face a myriad of sector specific licenses as well as inspections to enforce compliance. The Doing Business database constructs two sets of indicators on the regulation of operations. One measures the steps, time and costs of complying with licensing and permit requirements for ongoing. The other assesses the enforcement of regulations through two of the most common types of inspections-labor and tax. Registering Property: Property registries were first developed to help raise tax revenue. What was good for the tax authorities has since proven to be good for strengthening property rights-the registries strengthen incentives to invest, facilitate trade, and expand access to credit. New indicators cover the steps, time and cost to register property. Measures of the legal provisions that strengthen property rights and the efficiency of property registries are also developed. Protecting Investors: Corporate governance issues are often thought to affect only publicly listed companies in developed countries. In fact, corporate governance is relevant for every large privately held company that has more than one owner. New indicators examine several possible types of shareholder expropriation, including related-party transactions, guarantees and loans to company managers and directors, mergers and acquisitions, disclosure of ownership information, and treatment of conflicts of interest. Including a new emphasis on gender, Doing Business not only provides insights into business constraints throughout the world but highlights particular barriers faced by women. Doing Business is a comprehensive resource that no investor, economic adviser, business developer, or economic policymaker should be without.

This book focuses on the modeling of the transitions in and out of unemployment, given the stochastic processes that break up jobs and lead to the formation of new jobs, and on the implications of this approach for macroeconomic equilibrium and for the efficiency of the labor market. An equilibrium theory of unemployment assumes that firms and workers maximize their payoffs under rational expectations and that wages are determined to exploit the private gains from trade. This book focuses on the modeling of the transitions in and out of unemployment, given the stochastic processes that break up jobs and lead to the formation of new jobs, and on the implications of this approach for macroeconomic equilibrium and for the efficiency of the labor market. This approach to labor market equilibrium and unemployment has been successful in explaining the determinants of the "natural" rate of unemployment and new data on job and worker flows, in modeling the labor market in equilibrium business cycle and growth models, and in analyzing welfare policy. The second edition contains two new chapters, one on endogenous job destruction and one on search on the job and job-to-job quitting. The rest of the book has been extensively rewritten and, in several cases, simplified.

Amid total factor productivity (TFP) shocks job-to-job flows amplify the volatility of unemployment, but the aggregate implications of job-to-job flows amid financial shocks are less understood. To develop such understanding we model a general equilibrium labor-search framework that incorporates on-the-job (OTJ) search and distinctly accounts for the differential impact of TFP and financial shocks. Surprisingly, we find that the interaction of OTJ search with financial shocks is sufficiently different from its interaction with TFP shocks so that, under standard calibrations, our model generates aggregate dynamics exceedingly in line with the behavior of key U.S. macro data across several decades and in the wake of the Global Financial Crisis as well. Importantly, as in the data, the model yields relatively high volatilities of consumption, labor income, and unemployment. As such, our work contributes to resolving two limitations of current general equilibrium labor-search theory: under standard calibrations models without OTJ search generate implausibly low unemployment volatility, while models with OTJ search generate unemployment volatility closer to the data but at the expense of implausibly low consumption and labor-income volatility.

The 20th NBER Macroeconomics Annual, covering questions at the cutting edge of macroeconomics that are central to current policy debates.

A proposal that the notion of specificity -- the idea that factors of production are not interchangeable -- can provide a unified framework to analyze and understand a wide variety of macroeconomic phenomena stemming from the transactional environment and microeconomic restructuring. The core mechanism that drives economic growth in modern market economies is massive microeconomic restructuring and factor reallocation -- the Schumpeterian "creative destruction" by which new technologies replace the old. At the microeconomic level, restructuring is characterized by countless decisions to create and destroy production arrangements. The efficiency of these decisions depends in large part on the existence of sound institutions that provide a proper transactional environment. In this groundbreaking book, Ricardo Caballero proposes a unified framework to analyze and understand a wide variety of macroeconomic phenomena stemming from limitations, especially institutional, that hinder these adjustments. Caballero argues that macroeconomic models need to be made more "structural" in a precise sense and can not be maintained on the assumption that decisions are fully flexible. What is needed, he proposes, is the notion of specificity -- the idea that factors of production are not freely interchangeable. Many of the major macroeconomic developments of recent decades, he argues, fit naturally into this perspective, including the transition problems of Eastern Europe, the heavy weight of labor regulations in Western Europe, the emerging market crises of the 1990s, the prolonged expansion of the U.S. economy, and Japan's stagnation following the collapse of its real estate bubble. After describing the basic arguments of the book and developing models to illustrate two different kinds of specificity (relationship specificity and technological specificity), Caballero analyzes a variety of aspects of inefficient restructuring and revisits perennial business cycle patterns such as the cyclical behavior of unemployment, investment, and wages. Finally, he looks at the endogenous response of political institutions and technology to opportunistic exploitation of relationship specificity. Economists working on macroeconomics, development, growth, labor, and productivity issues will find Caballero's conceptual framework applicable to phenomena in their fields.

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.
