From the traditional craft hiring hall to the Web site Monster.com, a multitude of institutions exist to facilitate the matching of workers with firms. The diversity of such Labor Market Intermediaries (LMIs) encompasses criminal records providers, public employment offices, labor unions, temporary help agencies, and centralized medical residency matches. Studies of Labor Market Intermediation analyzes how these third-party actors intercede where workers and firms meet, thereby aiding, impeding, and, in some cases, exploiting the matching process. By building a conceptual foundation for analyzing the roles that these understudied economic actors serve in the labor market, this volume develops both a qualitative and quantitative sense of their significance to market operation and worker welfare. Cross-national in scope, Studies of Labor Market Intermediation is distinctive in coalescing research on a set of market institutions that are typically treated as isolated entities, thus setting a research agenda for analyzing the changing shape of employment in an era of rapid globalization and technological change.

Labor Market Intermediaries (LMIs) are entities or institutions that interpose themselves between workers and firms to facilitate, inform, or regulate how workers are matched to firms, how work is accomplished, and how conflicts are resolved. This paper offers a conceptual foundation for analyzing the market role played by these understudied institutions, and to develop a qualitative and, in some cases, quantitative sense of their significance to market operation and welfare. Though heterogeneous, I argue that LMIs share a common function, which is to redress -- and in some cases exploit -- a set of endemic departures of labor market operation from the efficient neoclassical benchmark. At a rudimentary level, LMIs such as online job boards reduce search frictions by aggregating and reselling disparate information at a cost below which workers and firms could obtain themselves. Beyond passively supplying information, a set of LMIs forcibly redress adverse selection problems in labor markets by compelling workers and firms to reveal normally hidden credentials, such as criminal background, academic standing, or financial integrity. At their most forceful, LMIs such as labor unions and centralized job matching clearinghouses, resolve coordination and collective action failures in markets by tightly controlling -- even monopolizing -- the process by which workers and firms meet, match and negotiate. A unifying observation of the analytic framework is that participation in the activities of a given LMI are typically voluntary for one side of the market and compulsory for the other; workers cannot, for example, elect to suppress their criminal records and firms cannot opt out of collective bargaining. I argue that the nature of participation in an LMI's activities -- voluntary or compulsory, and for which parties -- is dictated by the market imperfection that it addresses and thus tells us much about its economic function.

This book constitutes the refereed proceedings of the 6th International Workshop on Internet and Network Economics, WINE 2010, held in Stanford, USA, in December 2010. The 52 revised full papers presented were carefully reviewed and selected from 95 submissions. The papers are organized in 33 regular papers and 19 short papers.

Globalization, technological change, and deregulation have made the American marketplace increasingly competitive in recent decades, but for many workers this "new economy" has entailed heightened job insecurity, lower wages, and scarcer benefits. As the job market has grown more volatile, a variety of labor market intermediaries—organizations that help job seekers find employment—have sprung up, from private temporary agencies to government "One-Stop Career Centers." In Staircases or Treadmills? Chris Benner, Laura Leete, and Manuel Pastor investigate what approaches are most effective in helping workers to secure jobs with decent wages and benefits, and they provide specific policy recommendations for how job-matching organizations can better serve disadvantaged workers. Staircases or Treadmills? is the first comprehensive study documenting the prevalence of all types of labor market intermediaries and investigating how these intermediaries affect workers' employment opportunities. Benner, Leete, and Pastor draw on years of research in two distinct regional labor markets—"old economy" Milwaukee and "new economy" Silicon Valley—including a first-of-its-kind random survey of the prevalence and impacts of intermediaries, and a wide range of interviews with intermediary agencies' staff and clients. One of the main obstacles that disadvantaged workers face is that social networks of families and friends are less effective in connecting job-seekers to stable, quality employment. Intermediaries often serve as a substitute method for finding a job. Which substitute is chosen, however, matters: The authors find that the most effective organizations—including many unions, community colleges, and local non-profits—actively foster contacts between workers and employers, tend to make long-term investments in training for career development, and seek to transform as well as satisfy market demands. But without effective social networks to help workers locate the best intermediaries, most rely on private temporary agencies and other organizations that offer fewer services and, statistical analysis shows, often channel their participants into jobs with low wages and few benefits. Staircases or Treadmills? suggests that, to become more effective, intermediary organizations of all types need to focus more on training workers, teaching networking skills, and fostering contact between workers and employers in the same industries. A generation ago, rising living standards were broadly distributed and coupled with relatively secure employment. Today, many Americans fear that heightened job insecurity is overshadowing the benefits of dynamic economic growth. Staircases or Treadmills? is a stimulating guide to how private and public job-matching institutions can empower disadvantaged workers to share in economic progress.

Searching for a job has been an everyday affair in both modern and past societies, and employment a concern for both individuals and institutions. The case studies in this volume investigate job search and placement practices in European countries, Australia, and India in the nineteenth and twentieth centuries. The contributors explore how looking for work becomes a means by which participants (individuals, placement agents, trade unions, municipalities, administrations, state authorities, and schools) articulated specific interests, perspectives, and agendas. Taking an exploratory approach, the chapters illustrate different approaches to the history of employment and job searching, ranging from organizational and regulatory histories to the analysis of practices and autobiographical accounts. In the process, they uncover the interrelations of search practices and attempts to arrange placement services.

This paper evaluates the impact of the availability of electronic labor markets on university-to-work transition. In particular, we analyze the effect of the intermediation activity carried on by the interuniversity consortium AlmaLaurea on graduates' labor market outcomes. Different timing of universities' enrolment in AlmaLaurea produces counterfactuals that allow us to overcome the problems faced by previous empirical investigations. The evaluation is performed applying the difference-in-differences method to a repeated cross section data set. It is shown that, if the usual assumption concerning parallel outcomes holds, AlmaLaurea reduces individual unemployment probability and improves matching quality. Interestingly, it is also found that on-line intermediaries foster graduates' geographical mobility. -- Labor Markets Intermediaries ; Job Search ; Electronic Markets
