Reverse-Engineering Censorship in China, at Stanford University, Computer Science, Data Science, Friday, January 16, 2015:
Slides

Chinese government censorship of social media constitutes the largest selective suppression of human communication in recorded history. In three ways, we show, paradoxically, that this large system also leaves large footprints that reveal a great deal about itself and the intentions of the government. First is an observational study where we download all social media posts before the Chinese government can read and censor those they deem objectionable, and then detect from a network of computers all over the world which are censored. Second, we conduct

Simplifying Matching Methods for Causal Inference, at Stanford University, Department of Political Science, Wednesday, January 14, 2015:
Slides

This talk explains how to make matching methods for causal inference easier to use and more powerful. Applied researchers commonly use matching methods as a data preprocessing step for reducing model dependence and bias, after which they use whatever statistical procedure they would have without matching, such as regression. They routinely ignore the requirement that all matches be exact, and also commonly use ad hoc analyses that iterate between formal

Public Policy for the Poor? A Randomized Evaluation of the Mexican Universal Health Insurance Program, at Harvard School of Public Health (Foundations of Global Health and Population), Friday, October 10, 2014:
Slides
An evaluation of the Mexican Seguro Popular program (designed to extend health insurance and regular and preventive medical care, pharmaceuticals, and health facilities to 50 million uninsured Mexicans), one of the world's largest health policy reforms of the last two decades. Our evaluation features a new design for field experiments that is more robust to the political interventions and
