disco: Distributional Synthetic Controls
Florian Gunsilius, David Van Dijcke
The method of synthetic controls is widely used for evaluating causal effects of policy changes in settings with observational data. Often, researchers aim to estimate the causal i…
On the Differential-Geometric Equivalence of Hellinger-Kantorovich and Cone-Wasserstein Spaces
Tristan Luca Saidi, Gonzalo Mena, Florian Gunsilius
The Hellinger-Kantorovich (HK) space provides a natural geometry for nonnegative measures with varying total mass, but its differential-geometric structure is less well understood…
Wasserstein Parallel Transport for Predicting the Dynamics of Statistical Systems
Tristan Luca Saidi, Gonzalo Mena, Larry Wasserman +1
Many scientific systems, such as cellular populations or economic cohorts, are naturally described by probability distributions that evolve over time. Predicting how such a system…
Nonparametric Testability of Slutsky Symmetry
Florian Gunsilius, Lonjezo Sithole
Economic theory implies strong limitations on what types of consumption behavior are considered rational. Rationality implies that the Slutsky matrix, which captures the substituti…
Free Discontinuity Regression: With an Application to the Economic Effects of Internet Shutdowns
Florian Gunsilius, David Van Dijcke
Sharp, multidimensional changepoints-abrupt shifts in a regression surface whose locations and magnitudes are unknown-arise in settings as varied as gene-expression profiling, fina…
A primer on optimal transport for causal inference with observational data
Florian F Gunsilius
The theory of optimal transportation has developed into a powerful and elegant framework for comparing probability distributions, with wide-ranging applications in all areas of sci…
