In this important new Handbook, the editors have gathered together a range of leading contributors to introduce the theory and practice of multilevel modeling. The Handbook establishes the connections in multilevel modeling, bringing together leading experts from around the world to provide a roadmap for applied researchers linking theory and practice, as well as a unique arsenal of state-of-the-art tools. It forges vital connections that cross traditional disciplinary divides and introduces best practice in the field. Part I establishes the framework for estimation and inference, including chapters dedicated to notation, model selection, fixed and random effects, and causal inference. Part II develops variations and extensions, such as nonlinear, semiparametric and latent class models. Part III includes discussion of missing data and robust methods, assessment of fit and software. Part IV consists of exemplary modeling and data analyses written by methodologists working in specific disciplines. Combining practical pieces with overviews of the field, this Handbook is essential reading for any student or researcher looking to apply multilevel techniques in their own research.

The promise of upward mobility—the notion that everyone has the chance to get ahead—is one of this country's most cherished ideals, a hallmark of the American Dream. But in today's volatile labor market, the tradition of upward mobility for all may be a thing of the past. In a competitive world of deregulated markets and demanding shareholders, many firms that once offered the opportunity for advancement to workers have remade themselves as leaner enterprises with more flexible work forces. Divergent Paths examines the prospects for upward mobility of workers in this changed economic landscape. Based on an innovative comparison of the fortunes of two generations of young, white men over the course of their careers, Divergent Paths documents the divide between the upwardly mobile and the growing numbers of workers caught in the low-wage trap. The first generation entered the labor market in the late 1960s, a time of prosperity and stability in the U.S. labor market, while the second generation started work in the early 1980s, just as the new labor market was being born amid recession, deregulation, and the weakening of organized labor. Tracking both sets of workers over time, the authors show that the new labor market is more volatile and less forgiving than the labor market of the 1960s and 1970s. Jobs are less stable, and the penalties for failing to find a steady employer are more severe for most workers. At the top of the job pyramid, the new nomads—highly credentialed, well-connected workers—regard each short-term project as a springboard to a better-paying position, while at the bottom, a growing number of retail workers, data entry clerks, and telemarketers, are consigned to a succession of low-paying, dead-end jobs. While many commentators dismiss public anxieties about job insecurity as overblown, Divergent Paths carefully documents hidden trends in today's job market which confirm many of the public's fears. Despite the celebrated job market of recent years, the authors show that the old labor market of the 1960s and 1970s propelled more workers up the earnings ladder than does today's labor market. Divergent Paths concludes with a discussion of policy strategies, such as regional partnerships linking corporate, union, government, and community resources, which may help repair the career paths that once made upward mobility a realistic ambition for all American workers.
