Ethnic Politics and Women's Empowerment in Africa: Ministerial Appointments to Executive Cabinets

Under what conditions do women participate in executive power in multiethnic societies? Previous research has examined how political institutions, socioeconomic factors, and cultural norms affect the appointment of women as cabinet ministers. However, no study has assessed the extent to which the politicization of ethnicity—a cleavage that shapes political life in many countries—affects women's cabinet appointments. Focusing on sub‐Saharan Africa, we argue that women are less likely to become cabinet ministers where incumbents use such appointments to build patronage‐based alliances with politicians who act as advocates for ethnic constituencies. Using an original dataset on the composition of cabinets in 34 African countries from 1980 to 2005, we show that women's share of cabinet appointments is significantly lower in countries where leaders must accommodate a larger number of politicized ethnic groups, but it rises with higher levels of democracy and greater representation of women in parliament.     

Guilt by association: The link between states�� influence and the legitimacy of intergovernmental organizations

Unfavorable views toward a particular state will result in skepticism about the legitimacy of IGOs in which that state possesses influence. The more extensive the avenues of influence, the stronger this “guilt by association.” The rationale is two-fold. First, a state that possesses institutionalized influence (e.g., a veto) within an intergovernmental organization faces substantial difficulties in credibly committing to non-interference with organizational activities. Second, even if a state somehow could commit to abstention from overt interference, it may exert covert ideational influence if it already has embedded its values into an IGO. Elites and laypeople alike recognize the avenues of influence that fuel guilt-by-association. With statistical analyses of public opinion data from 35,397 people in 23 countries, I provide the first systematic evidence that guilt-by-association exists: for the United States, Russia, Japan, and Pakistan, vis-à-vis the United Nations, World Bank, and International Monetary Fund. The evidence is robust to numerous alternative specifications. The findings contribute to international relations scholarship by enhancing our understanding of threats to IGO legitimacy and by providing concrete evidence for a mechanism by which antipathy toward powerful states matters in the international realm.     

Dynamics of Polarizing Rhetoric in Congressional Tweets

Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric via a novel and highly accurate application of supervised machine learning methods. Fitting with our expectations, we find that more ideologically extreme members, those from safer districts, and those who are not in the president’s party are more likely to send polarizing tweets, and that polarizing tweets garner more engagement, increasing campaign funding for more polarizing members.
