Drawing on recent advances in the social sciences, this volume shows how rigorous, theory-based empirical research can help improve the management of public policies and programs - and how better governance can lead to better performance. These original essays demonstrate how better data and improved statistical techniques have allowed researchers to construct more complex models of governance processes and thereby assess the effects of many variables on policy and program outcomes. They present useful research results that illuminate such issues as automatic grade advancement in public schools, management of federally-funded job-training programs, reducing welfare caseloads, and management of welfare-to-work programs. Illustrating a range of theoretical and methodological possibilities, this book shows how more sophisticated research in public management can help improve government performance.
