Testing Theories of American Politics: Elites, Interest Groups, and Average Citizens

September, 2014

Abstract

Each of four theoretical traditions in the study of American politics—which can be characterized as theories of Majoritarian Electoral Democracy, Economic-Elite Domination, and two types of interest-group pluralism, Majoritarian Pluralism and Biased Pluralism—offers different predictions about which sets of actors have how much influence over public policy: average citizens; economic elites; and organized interest groups, mass-based or business-oriented.

Four Stylized Facts about COVID19 - Study of Nonpharmaceutical Interventions

August, 2020

Abstract

We document four facts about the COVID-19 pandemic worldwide relevant for those studying the impact of non-pharmaceutical interventions (NPIs) on COVID-19 transmission.

First: across all countries and U.S. states that we study, the growth rates of daily deaths from COVID-19 fell from a wide range of initially high levels to levels close to zero within 20-30 days after each region experienced 25 cumulative deaths.

Second: after this initial period, growth rates of daily deaths have hovered around zero or below everywhere in the world.
