    How to Make Causal Inferences with Time-Series Cross-Sectional Data under Selection on Observables

    How to Make Causal Inferences with Time-Series Cross-Sectional Data under Selection on Observables by Matthew Blackwell, Harvard University and Adam N. Glynn, Emory University Repeated measurements of the same countries, people, or groups over time are vital to manyfields of political science. These measurements, sometimes called time­series cross­sectional (TSCS) data, allow researchers to estimate a broad set of causal quantities, including contemporaneous effects and direct effects of lagged treatments. Unfortunately, popular  methods for TSCS data can only produce valid inferences for lagged effects under very strong  assumptions. In this paper, we use potential outcomes to define causal quantities of interest in  this settings and clarify how standard models like the autoregressive distributed lag model can  produce biased estimates of these quantities due to post­treatment conditioning even when a  selection on observables assumption holds. We then describe two estimation strategies that  avoid these post­treatment biases­­­inverse probability weighting and structural nested mean  models­­­and show via simulations that they can outperform standard approaches in small  sample settings. We illustrate these methods in a study of how welfare spending affects  terrorism.
