PUBLIC POLICY: AN EVOLUTIONARY APPROACH, 3e, examines how the substance and process of public policy and our understanding of that have evolved in America. After providing the reader with an analytic, historic and contextual framework for viewing public policy in the U.S., the authors offer a comprehensive look at the various elements of the governing process including agenda setting and problem definition, policy formation, implementation, program evaluation, and policy change and termination. In doing that the authors pay particular attention to the range of theories that have been offered to explain how, why, and with what effects governments act. The authors then look at three critical policy areas - environment, education, and welfare - to further illustrate how governing proceeds in the U.S.. Throughout the text the authors draw extensively on actual policy examples including recent efforts to reform education and welfare and the war in Iraq.
