A new paper introduces Hierarchical Causal Models (HCMs) to address causal inference challenges in hierarchical data structures. These models extend traditional graphical models by incorporating nested structures, enabling causal identification even when unit-level summaries are the only available data. The research also presents estimation strategies, including hierarchical Bayesian models, and demonstrates their application through simulations and a reanalysis of the "eight schools" study. AI
