The contributors explore the reasons why involuntary unemployment happens when supply equals demand.

The paper analyzes the role of labor market segmentation and relative wage rigidity in the transmission process of macroeconomic shocks in a two-sector optimizing model of a small open economy. The analysis is first conducted in the context of perfect intersectoral labor mobility. The discussion is then extended to consider the existence of short-run constraints on labor movements. The results highlight the role of efficiency considerations in the behavior of sectoral wages. A deflationary policy induces a reallocation of labor across sectors, but has no long-run effect on the unemployment rate.

The distribution of income, the rate of pay raises, and the mobility of employees is crucial to understanding labor economics. Although research abounds on the distribution of wages across individuals in the economy, wage differentials within firms remain a mystery to economists. The first effort to examine linked employer-employee data across countries, The Structure of Wages:An International Comparison analyzes labor trends and their institutional background in the United States and eight European countries. A distinguished team of contributors reveal how a rising wage variance rewards star employees at a higher rate than ever before, how talent becomes concentrated in a few firms over time, and how outside market conditions affect wages in the twenty-first century. From a comparative perspective that examines wage and income differences within and between countries such as Denmark, Italy, and the Netherlands, this volume will be required reading for economists and those working in industrial organization.

In Let Their People Come, Lant Pritchett discusses five "irresistible forces" of global labor migration, and the "immovable ideas" that form a political backlash against it. Increasing wage gaps, different demographic futures, "everything but labor" globalization, and the continued employment growth in low skilled, labor intensive industries all contribute to the forces compelling labor to migrate across national borders. Pritchett analyzes the fifth irresistible force of "ghosts and zombies," or the rapid and massive shifts in desired populations of countries, and says that this aspect has been neglected in the discussion of global labor mobility. Let Their People Come provides six policy recommendations for unskilled immigration policy that seek to reconcile the irresistible force of migration with the immovable ideas in rich countries that keep this force in check. In clear, accessible prose, this volume explores ways to regulate migration flows so that they are a benefit to both the global North and global South.

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources of cross-sectional data on vacancies, JOLTS and HWOL, a new database covering the universe of online U.S. job advertisements. Mismatch across industries and occupations explains at most 1/3 of the total observed increase in the unemployment rate, whereas geographical mismatch plays no apparent role. The share of the rise in unemployment explained by occupational mismatch is increasing in the education level.

The Economic and Fiscal Consequences of Immigration finds that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. This report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. More than 40 million people living in the United States were born in other countries, and almost an equal number have at least one foreign-born parent. Together, the first generation (foreign-born) and second generation (children of the foreign-born) comprise almost one in four Americans. It comes as little surprise, then, that many U.S. residents view immigration as a major policy issue facing the nation. Not only does immigration affect the environment in which everyone lives, learns, and works, but it also interacts with nearly every policy area of concern, from jobs and the economy, education, and health care, to federal, state, and local government budgets. The changing patterns of immigration and the evolving consequences for American society, institutions, and the economy continue to fuel public policy debate that plays out at the national, state, and local levels. The Economic and Fiscal Consequences of Immigration assesses the impact of dynamic immigration processes on economic and fiscal outcomes for the United States, a major destination of world population movements. This report will be a fundamental resource for policy makers and law makers at the federal, state, and local levels but extends to the general public, nongovernmental organizations, the business community, educational institutions, and the research community.
