Quasi-Experimentation


Book Description

Featuring engaging examples from diverse disciplines, this book explains how to use modern approaches to quasi-experimentation to derive credible estimates of treatment effects under the demanding constraints of field settings. Foremost expert Charles S. Reichardt provides an in-depth examination of the design and statistical analysis of pretest–posttest, nonequivalent groups, regression discontinuity, and interrupted time-series designs. He details their relative strengths and weaknesses and offers practical advice about their use. Comparing quasi-experiments to randomized experiments, Reichardt discusses when and why the former might be a better choice than the latter in the face of the contingencies that are likely to arise in practice. Modern methods for elaborating a research design to remove bias from estimates of treatment effects are described, as are tactics for dealing with missing data and noncompliance with treatment assignment. Throughout, mathematical equations are translated into words to enhance accessibility. Adding to its discussion of prototypical quasi-experiments, the book also provides a complete typology of quasi-experimental design options to help the reader craft the best research design to fit the circumstances of a given study.




Experimental Social Programs and Analytic Methods


Book Description

Experimental Social Programs and Analytic Methods: An Evaluation of the U.S. Income Maintenance Projects examines the statistical and econometric research on work disincentive effects reported by a series of social experiments that explore the economic and social consequences of a guaranteed income program. This book provides a comparative description of the several experimental designs and labor supply results, including a general discussion of methodological issues common to the social experiments. The Conlisk-Watts model for sample assignment and labor supply findings from both an econometric and statistical perspective are also elaborated. This text likewise presents an updated survey of the work response findings from the American negative income tax experiments. This publication is intended for professionals and students in econometrics, labor economics, statistics, and quantitative research, but is also valuable to policy analysts and others concerned with social welfare reform and public administration.




Process Mapping


Book Description

A business organization, like a human body, is only as effective as its various processes. Pretty obvious, right? Yet, as V. Daniel Hunt demonstrates in this groundbreaking book, the failure to appreciate this obvious fact is the reason most reengineering schemes fail. Managers whose job it is to improve company performance, like physicians who work to improve patient health, must develop a clear picture of how each process fits into the overall organizational structure; how it ought to function; and how well it is performing at any given moment; before they can form a diagnosis or devise a treatment strategy. Fortunately, a powerful new analytical tool that has emerged in recent years helps you to do all of that and much more. Developed at General Electric, process mapping has been implemented in companies around the globe, and the results have been simply astonishing. Now find out how to make this breakthrough reengineering technology work for your organization in Process Mapping. The first and only hands-on guide of its kind, Process Mapping arms you with a full complement of state-of-the-art tools and techniques for assessing existing business processes and developing a detailed road map for ongoing change and improvement. Internationally known management consultant and bestselling author V. Daniel Hunt guides you step-by-step through the entire process. He helps you assess the need for process reengineering in your organization and determine whether or not a process map is what you need. He shows you how to create a process mapping team and helps you select the best-buy process mapping tools for the job. He explains how to gather vital information about your business processes via focused interviews and other interview techniques, and how to use this data in implementing process mapping. He also offers expert advice on how to apply your process map to significantly improve business functions and bottom-line performance. Hunt draws upon the experiences of companies around the world whose process mapping success stories will be a source of inspiration and instruction. You'll find out just how process mapping was put to use--and the results it achieved--at General Electric, IBM, NASA, Tandy Electronics, Shawmut National Bank, Fluor Daniel, Exxon, and other leading product and service firms. Find out all about today's most important new management tool and how to put it to work for continuous improvement in your organization in Process Mapping. The first and only hands-on guide to a powerful new process mapping tool The most important new process improvement tool to come along in more than a decade, process mapping enables managers to easily identify and assess the various business processes that make up their organizations and to develop a road map for continued performance improvement. Now find out how to make this breakthrough management tool work in your organization by applying Process Mapping. V. Daniel Hunt, the bestselling author of Reengineering, Quality in America, and The Survival Factor, guides you step-by-step through the entire process. He gives you all the proven process mapping tools and techniques you need to: * Assess the need for process improvement in your company * Decide if process mapping is right for you * Create a process mapping team * Select the best process mapping software tools for the job * Collect vital information about business processes * Use the data to build your own process map * Use your process map to significantly improve bottom-line business performance Hunt also provides detailed case studies of product and service companies around the globe that have discovered the value of process mapping. You'll find out how General Electric, IBM, NASA, Tandy Electronics, Shawmut National Bank, Fluor Daniel, Exxon, and other leading companies achieved stunning results when they made process mapping part of their business improvement efforts.
