Conventional causal parameters, such as the average treatment effect (ATE), reflect how the mean outcome in a population or subpopulation would change if all units received treatment versus control. Real-world policy changes, however, are often incremental, changing the treatment status for only a small segment of the population who are at or near “the margin of participation.” To mimic real-world policy changes, two parallel lines of literature have developed in statistics/epidemiology and in economics/sociology that define, identify, and estimate what we call interventional effects and marginal interventional effects. The goal of this workshop is to introduce these two lines of literature, unify them under a common set of notation and definitions, propose new identification and estimation results that will be illustrated with two examples.

Workshop outline
Day 1 (May 10): Causal inference with observational data
Day 2 (May 11): Instrumental variables and marginal treatment effects
Day 3 (May 12): Interventional effects

Maximum number of participants will be 30. Priority will be given to members and alumni of the Department of Sociology and those with prior training in the counterfactual approach to causal inference.
