Through a comparative examination of institutions and testing theories of the use of policy analysis, Hird draws conclusions that are more useful than those derived from single cases. Hird examines nonpartisan policy research organizations established by and operating in U.S. state legislatures - one of the most intense of political environments - to determine whether and how nonpartisan policy research can survive in that harsh climate. By first detailing how nonpartisan policy analysis organizations came to be and what they do, and then determining what state legislators want from them, he presents a rigorous statistical analysis of those agencies in all 50 states and from a survey of 800 state legislators. This thoroughly comprehensive look at policymaking at the state level concludes that nonpartisan policy analysis institutions can play an important role - as long as they remain scrupulously nonpartisan.
