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),...

Valoriser les processus pour élaborer des cahiers des charges: une approche innovante

Venteicher, Francesca ; Widmer, Marino

(Internal working papers DIUF ; 18-02)

Lors de la fusion de communes, l’organisation des services du feu et leur efficacité dans la lutte contre les incendies et autres sinistres est une préoccupation des autorités cantonales. L’accroissement des activités socio-économiques et des besoins humains exerce une pression grandissante sur les corps des sapeurs-pompiers (CSP), créant des difficultés de recrutement et de...

Finding the adequate location scenario after the merger of fire brigades thanks to Multiple Criteria Decision Analysis Methods

Aldabbas, Mohammad ; Venteicher, Francesca ; Gerber, Lenna ; Widmer, Marino

(Internal working papers DIUF ; 18-01)

This paper addresses the issue of selecting a suitable location for a fire station in canton of Fribourg, as a result of a fire brigades’merger, by applying Multiple Criteria Decision Analysis (MCDA) methods. Solving the problem of determining fire station locations through various methods has been analyzed in-­‐depth by researchers. However, a different approach, based on application of...

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 ...

Instrument-based estimation with binarized treatments : issues and tests for the exclusion restriction

Andresen, Martin Eckhoff ; Huber, Martin

(Working Papers SES ; 492)

When estimating local average and marginal treatment effects using instrumental variables (IV), multivalued endogenous treatments are frequently binarized based on a specific threshold in treatment support. However, such binarization introduces a violation of the IV exclusion if (i) the IV affects the multivalued treatment within support areas below and/or above the threshold and (ii) such...

Family firms and financial analyst activity

Eugster, Nicolas

(Working Papers SES ; 491)

This paper examines the relationship between ownership structure, analyst coverage, and forecast error for the entire population of non-financial companies listed on the Swiss Exchange for the period 2003-2013. The results show a negative association between concentrated ownership and analyst coverage for both family firms and firms held by a nonfamily blockholder. Furthermore, forecasts of...

Exploring nuances of user privacy preferences on a platform for political participation

Kaskina, Aigul

(Internal working papers / DIUF ; 17-02)

A problematic gap between existing online privacy controls and actual user disclosure behavior motivates researchers to focus on a design and development of intelligent privacy controls. These intelligent controls intend to decrease the burden of privacy decision-making and generate user-tailored privacy suggestions. To do so, at first it is necessary to analyze user privacy preferences. Previous...

Founding family ownership, stock market returns, and agency problems

Eugster, Nicolas ; Isakov, Dušan

(Working Papers SES ; 490)

This paper explores the relationship between founding family ownership and stock market returns. Using the entire population of non-financial firms listed on the Swiss stock market for 2003–2013, we find that the stock returns of family firms are significantly higher than those of non-family firms after adjusting the returns for different risk factors and firm characteristics. Family firms...

Including covariates in the regression discontinuity design

Frölich, Markus ; Huber, Martin

(Working Papers SES ; 489)

This paper proposes a fully nonparametric kernel method to account for observed covariates in regression discontinuity designs (RDD), which may increase precision of treatment effect estimation. It is shown that conditioning on covariates reduces the asymptotic variance and allows estimating the treatment effect at the rate of one-dimensional nonparametric regression, irrespective of the...

Peer effects on perseverance

Buechel, Berno ; Mechtenberg, Lydia ; Petersen, Julia

(Working Papers SES ; 488)

Successful performance – be it in school, at the job, or in sports activities – requires perseverance, i.e., persistent work on a demanding task. We investigate in a controlled laboratory experiment how an individual’s social environment affects perseverance. We find evidence for two kinds of peer effects: being observed by a peer can serve as a commitment device, while observing a peer can...
