Coworker shooting performance, meaningfully impacts both, manager decisions and third-party expert evaluations of individual performance.

Causal Machine Learning for Moderation Effects

no code implementations16 Jan 2024 Nora Bearth, Michael Lechner

Adding additional identifying assumptions allows specific balanced differences in treatment effects between groups to be interpreted causally, leading to the causal balanced group average treatment effect.

The finite sample performance of instrumental variable-based estimators of the Local Average Treatment Effect when controlling for covariates

no code implementations14 Dec 2022 Hugo Bodory, Martin Huber, Michael Lechner

This paper investigates the finite sample performance of a range of parametric, semi-parametric, and non-parametric instrumental variable estimators when controlling for a fixed set of covariates to evaluate the local average treatment effect.

Modified Causal Forest

no code implementations8 Sep 2022 Michael Lechner, Jana Mareckova

Uncovering the heterogeneity of causal effects of policies and business decisions at various levels of granularity provides substantial value to decision makers.

Active labour market policies for the long-term unemployed: New evidence from causal machine learning

no code implementations18 Jun 2021 Daniel Goller, Tamara Harrer, Michael Lechner, Joachim Wolff

Active labor market programs are important instruments used by European employment agencies to help the unemployed find work.

The Effect of Sport in Online Dating: Evidence from Causal Machine Learning

no code implementations7 Apr 2021 Daniel Boller, Michael Lechner, Gabriel Okasa

We find that for male users, doing sport on a weekly basis increases the probability to receive a first message from a woman by 50%, relatively to not doing sport at all.

Priority to unemployed immigrants? A causal machine learning evaluation of training in Belgium

no code implementations30 Dec 2019 Bart Cockx, Michael Lechner, Joost Bollens

Based on administrative data of unemployed in Belgium, we estimate the labour market effects of three training programmes at various aggregation levels using Modified Causal Forests, a causal machine learning estimator.

Random Forest Estimation of the Ordered Choice Model

2 code implementations4 Jul 2019 Michael Lechner, Gabriel Okasa

In this paper we develop a new machine learning estimator for ordered choice models based on the random forest.

Modified Causal Forests for Estimating Heterogeneous Causal Effects

no code implementations22 Dec 2018 Michael Lechner

Uncovering the heterogeneity of causal effects of policies and business decisions at various levels of granularity provides substantial value to decision makers.
