Causal mediation analysis with double machine learning

Farbmacher, Helmut ; Huber, Martin ; Langen, Henrika ; Spindler, Martin

(Working Papers SES ; 515)

This paper combines causal mediation analysis with double machine learning to control for observed confounders in a data-driven way under a selection-on- observables assumption in a high-dimensional setting. We consider the average indirect effect of a binary treatment operating through an intermediate variable (or mediator) on the causal path between the treatment and the outcome, as well as...

The causalweight package for causal inference in R

Bodory, Hugo ; Huber, Martin

(Working Papers SES ; 493)

We describe R package “causalweight” for causal inference based on inverse probability weighting (IPW). The “causalweight” package offers a range of semiparametric methods for treatment or impact evaluation and mediation analysis, which incorporates intermediate outcomes for investigating causal mechanisms. Depending on the method, identification relies on selection on observables ...

A cautionary tale about control variables in IV estimation

Deuchert, Eva ; Huber, Martin

(Working Papers SES ; 453)

Many instrumental variable (IV) regressions include control variables to justify (conditional) independence of the instrument and the potential outcomes. The plausibility of conditional IV independence crucially depends on the timing when the control variables are determined. This paper systemically works through different IV models and discusses the (conditions for the) satisfaction of...

The challenge of dual career expatriate management in a specific host national environment: An exploratory study of expatriate and spouse adjustment in Switzerland based MNCs

Ravasi, Claudio ; Salamin, Xavier ; Davoine, Eric

(Working Papers SES ; 447)

The number of expatriates from global firms has been continuously increasing over the past decades as multinational companies still view expatriation as an important tool for sharing and transferring knowledge, controlling subsidiaries and developing workforce competencies. Expatriate management is still a costly and complex task for multinational companies. Adjustment, which has been defined as...

Chasing dividends during the COVID-19 pandemic

Eugster, Nicolas ; Ducret, Romain ; Isakov, Dušan ; Weisskopf, Jean-Philippe

(Working Papers SES ; 520)

This paper investigates the impact of the COVID-19 pandemic on the trading behavior of investors around ex-dividend dates in Europe. The sudden decrease in the number of companies paying dividends reduced the opportunities to capture dividends. The firms that have maintained dividend payments during the pandemic thus attracted more interest than before. This led to a doubling in the magnitude...

Combining experimental evidence with machine learning to assess anti-corruption educational campaigns among Russian university students

Denisova-Schmidt, Elena ; Huber, Martin ; Leontyeva, Elvira ; Solovyeva, Anna

(Working Papers SES ; 487)

This paper examines how anti-corruption educational campaigns affect the attitudes of Russian university students towards corruption and academic integrity. About 2,000 survey participants were randomly assigned to one of four different information materials (brochures or videos) about the negative consequences of corruption or to a control group. Using machine learning to detect effect...

Comparing Mobile Communication Service Prices Among Providers: A Hedonic Approach

Schöni, Olivier ; Seger, Lukas

(Working Papers SES ; 448)

The present article proposes a new approach to compare mobile communication service prices among different communications service providers. To this end, a hedonic model based on monthly phone bills is employed that relates billed amounts and the quantities of consumed mobile communication services. A linear hedonic regression model is separately estimated for each provider and then used to...

Das House Kapital

Grossmann, Volker ; Larin, Benjamin ; Steger, Thomas

(Working Papers SES ; 523)

The housing wealth-to-income ratio has been increasing in most developed economies since the 1950s. We provide a novel theory to explain this long-term pattern. We show analytically that house prices grow in the steady state if i) the housing sector is more land-intensive than the non-housing sector, or ii) technological progress in the construction sector is weaker than in the non-housing...

Direct and indirect effects based on changes-in-changes

Huber, Martin ; Schelker, Mark ; Strittmatter, Anthony

(Working Papers SES ; 508)

We propose a novel approach for causal mediation analysis based on changes-in- changes assumptions restricting unobserved heterogeneity over time. This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary intermediate variable (called mediator) and a direct effect running via other causal mechanisms. We...

Direct and indirect effects based on difference-in-differences with an application to political preferences following the Vietnam draft lottery

Deuchert, Eva ; Huber, Martin ; Schelker, Mark

(Working Papers SES ; 473)

This study empirically evaluates the impact of the war in eastern Ukraine on the political attitudes aThis paper proposes a difference-in-differences approach for disentangling a total treatment effect on some outcome into a direct impact as well as an indirect effect operating through a binary intermediate variable – or mediator – within strata defined upon how the mediator reacts to the...
