This book chronicles many of the most important workforce program experiments and the key lessons derived from the evaluations of both existing large-scale programs and the development of new interventions including low-cost experiments based on behavioral science methods. Stephen A. Wandner gathers contributions from a notable group of researchers who have extensive experience with USDOL workforce experiments. Together, they provide a comprehensive resource for anyone interested in designing, implementing, and evaluating public workforce experiments and in how such experiments can be used to influence public policy.
