Abstract
For those interested in understanding the role of government in modern life, important public policies have long been objects of close scrutiny. Traditionally, however, policies were treated only as outcomes that needed to be explained. More recently, there has been growing interest in the political consequences of policy development. Policies are no longer seen simply as effects, with attention focused on why these policies emerged. Policies have important repercussions as well: once adopted, they restructure the political and social environment that produced them.
