This book reveals the considerable variation in the levels of growth in a broad set of nonstandard work arrangements while presenting a comprehensive view of how, as a result, the nature of the employment relationship is changing within and among countries. The international roster of economists, sociologists, and labor law experts who contributed draw on cross-country variations in economic conditions and institutional characteristics to explain why some arrangements have grown faster in some countries than in others and what this means for workers. By considering a broad array of nonstandard work arrangements in a number of economies, the authors provide a richer understanding than if the focus had been limited to a single country of one or a short-list of employment arrangements.
