Power-holders and gate-keepers in political parties and governments continue to be primarily men. How are they responding to the increasing numbers of women who are seeking leadership roles in politics? Are they angels who embrace equality and fling open the doors to power? Are they devils who block women at every turn? Are they powerless against the increasing tide of feminism and inadvertently succumbing to the push for power from women? Most likely, these male elites are primarily concerned with maintaining their own power, which drives their reaction to women’s political inclusion. The Inclusion Calculation examines women’s inclusion from the perspective of men in power and offers a novel approach to understanding differences in women’s descriptive representation. The book argues that with declining legitimacy it is valuable for male elites to “strategically feminize,” associating themselves or their party with women, because citizens will interpret the increased presence of women as meaning that the party or government is becoming more honest, cooperative, and democratic. Using a combination of case studies from Latin America, Europe, and Africa, as well as large-N analyses, the book provides evidence that male elites are more likely to increase the number of women candidates on party lists or adopt a gender quota when “feminizing” is advantageous to the political careers of men. Women’s exclusion from government, then, is not a product of their own lack of effort or ability but rather a rational action of men in power to keep their power.
