About this paper
Yuta Kawakami, Jin Tian
This work develops a framework for analyzing the distributional properties of causal effects beyond average measures, enabling the identification and estimation of moments such as variance, skewness, and kurtosis of individual causal effects. The approach provides a deeper understanding of treatment effect heterogeneity and relationships between different treatments, which is valuable for personalized decision-making and policy design.
Key insights
- Analyzing higher-order moments (variance, skewness, kurtosis) of causal effects reveals crucial information about heterogeneity beyond what averages convey.
- Product moments capture complex interdependencies between multiple causal effects or outcomes, such as how effects on different outcomes covary.
- Identification of these unobservable moments can be achieved through specific causal assumptions (e.g., exogeneity and monotonicity) or by deriving bounds from observational data.
