The Impact of Gender Quotas is a theory-building and comparative exercise in elaborating concepts commonly used to analyze the broad impacts of gender quotas. The book begins with the argument that the means by which women enter politics may influence how, why and to what extent their presence affects political representation. Following a preface by Drude Dahlerup, one of the pioneers of gender quota research, the editors introduce the book with a conceptual framework for analyzing the impact of quotas, based upon descriptive, substantive and symbolic dimensions of representation. The book is subsequently organized into three sections, each devoted to analyzing one of the dimensions of representation, and each of these sections contains a chapter case study from one of four regions of the world (Western Europe, Latin America, Sub-Saharan Africa, and Asia). Each of the chapters follows a basic format instituted by the editors, with the goal of facilitating cross-case comparisons and broad theory-building. The editors conclude the book by summarizing the main themes and implications for future research on gender quotas.
