Many political surveys rely on post-stratification, raking, or related weighting adjustments to align respondents with the target population. But when respondents differ from nonre…
Testing identification in mediation and dynamic treatment models
Martin Huber, Kevin Kloiber, Lukas Laffers
We propose a test for the identification of causal effects in mediation and dynamic treatment models that is based on two sets of observed variables, namely covariates to be contro…
Double machine learning for sample selection models
Michela Bia, Martin Huber, Lukáš Lafférs
This paper considers the evaluation of discretely distributed treatments when outcomes are only observed for a subpopulation due to sample selection or outcome attrition. For ident…
Bounds on direct and indirect effects under treatment/mediator endogeneity and outcome attrition
Martin Huber, Lukáš Lafférs
Causal mediation analysis aims at disentangling a treatment effect into an indirect mechanism operating through an intermediate outcome or mediator, as well as the direct effect of…
Benchmark values for the net proton number fluctuations
Boris Tomasik, Ivan Melo, Lukas Laffers +1
We formulate a baseline model for the net-proton number fluctuations in ultrarelativistic heavy-ion collisions. Our model includes total baryon number conservation, fluctuations of…
