arXiv:2604.00915v2 Announce Type: replace Abstract: Estimation of heterogeneous long-term treatment effects (HLTEs) is relevant for personalized decision-making in marketing, economics, and medicine, where short-term observational datasets are often combined with long-term observational datasets. However, HLTE estimation is challenging due to limited overlap in treatment assignments or in long-term outcomes for certain subpopulations, which can lead to unstable HLTE estimates with large finite-sample variance. To address this challenge, we introduce the LT-O-learners (Long-Term Orthogonal Lear
The continuous development in AI and machine learning pushes for more sophisticated causal inference methods, especially for heterogeneous effects in complex, real-world data.
Improved estimation of heterogeneous long-term treatment effects can lead to more precise, personalized decision-making across critical sectors like healthcare, marketing, and economics.
The ability to more stably and accurately predict individual responses to interventions over time is enhanced, even with limited or noisy data.

More effective and tailored interventions become possible in fields traditionally challenged by long-term effect estimation.
Reduced waste in resource allocation as interventions are optimally matched to subpopulations, leading to improved outcomes and efficiency.
Ethical considerations surrounding algorithmic bias in personalized decision-making become more pronounced as these models gain broader adoption.
