This last of a three-volume report of a study done to assess the feasibility of large-scale, countercyclical public job creation covers the findings regarding the priorities among projects, indirect employment effects, skill imbalances, and administrative issues; and summarizes the overall findings, conclusions, and recommendations. (Volume 1, comprised of the report's first chapter, overviews and summarizes the entire study. The second volume, containing the second chapter, covers the methods and the findings with respect to activities, their job-creation potential, and related characteristics.) The content covers the last six chapters in the report. Chapter 3 on establishing priorities among activity areas covers unmet needs, program choices, and a multidimensional approach to program priorities. Focus of the fourth chapter is on estimating the overall employment effect of public service employment programs, including an overview of the model (estimating offsite employment changes and accounting for the effects of fiscal substitution) and a defining of activity clusters. Chapter 5 discusses the methods and findings regarding the supply of skills available for newly created public jobs, while the sixth chapter assesses the potential for skill imbalances. Chapter 7 discusses seven administrative and operational issues in implementing public job-creation programs. The final chapter summarizes the overall findings, conclusions, and policy recommendations. (EM)
