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.

This report quantifies labor mobility costs in developing countries and simulates the implied adjustment paths of employment and wages following a change in trade policy. High mobility costs are shown to reduce the potential gains to trade reform.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Jobs provide higher earnings and better benefits as countries grow, but they are also a driver of development. Poverty falls as people work their way out of hardship and as jobs empowering women lead to greater investments in children. Efficiency increases as workers get better at what they do, as more productive jobs appear, and less productive ones disappear. Societies flourish as jobs bring together people from different ethnic and social backgrounds and provide alternatives to conflict. Jobs are thus more than a byproduct of economic growth. They are transformational —they are what we earn, what we do, and even who we are. High unemployment and unmet job expectations among youth are the most immediate concerns. But in many developing countries, where farming and self-employment are prevalent and safety nets are modest are best, unemployment rates can be low. In these countries, growth is seldom jobless. Most of their poor work long hours but simply cannot make ends meet. And the violation of basic rights is not uncommon. Therefore, the number of jobs is not all that matters: jobs with high development payoffs are needed. Confronted with these challenges, policy makers ask difficult questions. Should countries build their development strategies around growth, or should they focus on jobs? Can entrepreneurship be fostered, especially among the many microenterprises in developing countries, or are entrepreneurs born? Are greater investments in education and training a prerequisite for employability, or can skills be built through jobs? In times of major crises and structural shifts, should jobs, not just workers, be protected? And is there a risk that policies supporting job creation in one country will come at the expense of jobs in other countries? The World Development Report 2013: Jobs offers answers to these and other difficult questions by looking at jobs as drivers of development—not as derived labor demand—and by considering all types of jobs—not just formal wage employment. The Report provides a framework that cuts across sectors and shows that the best policy responses vary across countries, depending on their levels of development, endowments, demography, and institutions. Policy fundamentals matter in all cases, as they enable a vibrant private sector, the source of most jobs in the world. Labor policies can help as well, even if they are less critical than is often assumed. Development policies, from making smallholder farming viable to fostering functional cities to engaging in global markets, hold the key to success.
