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...

Causal Pitfalls in the Decomposition of Wage Gaps

Huber , Martin

In: Journal of business & economic statistics, 2015, vol. 33, no. 2, p. 179-191

The decomposition of gender or ethnic wage gaps into explained and unexplained components (often with the aim to assess labor market discrimination) has been a major research agenda in empirical labor economics. This article demonstrates that conventional decompositions, no matter whether linear or nonparametric,areequivalenttoassuminga(probablytoo)simplemodelofmediation(aimed atassessing...

A review of causal mediation analysis for assessing direct and indirect treatment effects

Huber, Martin

(Working Papers SES ; 500)

Mediation analysis aims at evaluating the causal mechanisms through which a treatment or intervention affects an outcome of interest. The goal is to disentangle the total treatment effect into an indirect effect operating through one or several observed intermediate variables, the so-called mediators, as well as a direct effect reflecting any impact not captured by the observed mediator(s)....

Direct and indirect effects of continuous treatments based on generalized propensity score weighting

Hsu, Yu-Chin ; Huber, Martin ; Lee, Ying-Ying ; Pipoz, Layal

(Working papers SES ; 495)

This paper proposes semi- and nonparametric methods for disentangling the total causal effect of a continuous treatment on an outcome variable into its natural direct effect and the indirect effect that operates through one or several intermediate variables or mediators. Our approach is based on weighting observations by the inverse of two versions of the generalized propensity score (GPS),...

Argomentare per superare il conflitto : l'argomentazione nella mediazione

Greco Morasso, Sara

In: Sistemi intelligenti, 2012, vol. 3, p. 481-502

This paper sets out to analyze the role that argumentation may play in dispute resolution, in particular within the practice of dispute mediation. The focus is on the complex interplay of different argumentative discussions which are necessary for the parties to personally handle and possibly solve their conflict. This contribution focuses in particular on the mediator's role in a...

Argumentative and other communicative strategies of the mediation practice

Greco Morasso, Sara ; Rigotti, Eddo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009.

This work investigates how argumentation, namely the communicative exchange aimed at founding ones position in a reasonable fashion, is an essential condition for the fulfilment of the pragmatic goals of mediation, conceived of as a conflict resolution practice. In mediation, the parties are competent and responsible for the decision on the conflict, while the mediator helps them assume an...

The Metaphor of the Triangle in Theories of Human Development

Zittoun, Tania ; Gillespie, Alex ; Cornish, Flora ; Psaltis, Charis

In: Human Development, 2007, vol. 50, no. 4, p. 208-229

Developmental psychologists have a long history of using triangle metaphors to conceptualise the social constitution of psychological development. In this paper, we present a genealogy of triadic theories, to clarify their origins, distinctions between them, and to identify key themes for theoretical development. The analysis identifies three core triangle models in the developmental literature....

Gli ombudsman dei giornali come strumento di gestione della qualità giornalistica = Reader's representatives as instruments for management of journalism quality

Elia, Cristina ; Russ-Mohl, Stephan (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2007 ; 2007COM006.

Press ombudsmen are particularly visible in Anglo-Saxon countries and in Sweden, but they are also present in most European and Latin American countries. Many studies have been conducted to understand the origins, the role and the effectiveness of Anglo-Saxon ombudsmen but not much was known about ombudsmen active in the rest of the world. On the occasion of the function's 40th anniversary - the...
