How can women maximise their political influence? Does state feminism enhance the political representation of women? Should feminism be established in state institutions to treat women's concerns? Written by experts in the field, this book uses an innovative model of political influence to construct answers to these and other questions in the long-running debate over the political representation of women. The book assesses how states respond to women's demands for political representation both in terms of their inclusion as actors and the consideration of their interests in the decision making process. Debates on the issue vary from country to country, depending on institutional structures, women's movements, and other factors, and this book offers the first comparative account of the subject. The authors analyse eleven democracies in Europe and North America and present comprehensive research from the 1960s to the present.
