Gender differences in wage expectations

Fernandes, Ana ; Huber, Martin ; Vaccaro, Giannina

(Working Papers SES ; 516)

Using a survey on wage expectations among students at two Swiss institutions of higher education, we examine the wage expectations of our respondents along two main lines. First, we investigate the rationality of wage expectations by comparing average expected wages from our sample with those of similar graduates; we further examine how our respondents revise their expectations when provided...

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...

Bounds on direct and indirect effects under treatment/mediator endogeneity and outcome attrition

Huber, Martin ; Lafférs, Lukáš

(Working Papers SES ; 514)

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 the treatment on the outcome of interest. However, the evaluation of direct and indirect effects is frequently complicated by non-ignorable selection into the treatment and/or mediator, even after controlling for...

Machine learning approach for flagging incomplete bid-rigging cartels

Wallimann, Hannes ; Imhof, David ; Huber, Martin

(Working Papers SES ; 513)

We propose a new method for flagging bid rigging, which is particularly useful for detecting incomplete bid-rigging cartels. Our approach combines screens, i.e. statistics derived from the distribution of bids in a tender, with machine learning to predict the probability of collusion. As a methodological innovation, we calculate such screens for all possible subgroups of three or four bids...

M&A by Chinese POEs in developed countries : acquiring and bundling strategic assets

Wu, Juan ; Morschett, Dirk

(Working Papers SES ; 512)

Building on the resource-based view and based on 33 interviews with top executives of 11 Chinese private owned enterprises (POEs) and 15 Western target companies, this study is an in-depth multi-case analysis of Chinese crossborder merger and acquisitions. While literature has argued that acquisitions by Chinese companies in developed countries are motivated by asset-seeking, this study takes...

Langue d’origine et langue de scolarisation : dans quelle mesure les compétences en littéracie sont-elles transférables ? : Une synthèse = Herkunftssprache und Schulsprache: sind Literalitätskompetenzen übertragbar?: Das Wichtigste in Kürze

Lambelet, Amelia ; Berthele, Raphael ; Vanhove, Jan ; Desgrippes, Magalie ; Pestana, Carlos ; Decandio, Fabricio

(Rapports du Centre scientifique de compétence sur le plurilinguisme)

The project Heritage language and school language: are literacy skills transferable? (HELASCOT) addresses the linguistic development in migrant children of Portuguese descent in Switzerland. It focuses primarily on the children’s literacy skills (reading comprehension and writing skills) in their heritage language (i.e. Portuguese) and in the language of instruction in the region in which...

Einige der insgesamt 140 Vorstösse sind durch konkrete religionspolitische Ereignisse, kantonale Reformprozesse und natürlich Parteiprogramme geprägt. Im Hintergrund werden jedoch zwei politische Agenden sichtbar: Während die eine auf...

Health consequences of sterilizations

La Rupelle, Maëlys de ; Dumas, Christelle

(Working Papers SES ; 503 (revised))

In India, as in many developing countries, female sterilization is the main contraceptive method: 37% of women older than 25 are sterilized. However, no economic study assesses the eect of sterilization, providing guidance on ecient reproductive health policies. We analyze the consequences of sterilization for maternal health, considering the endogeneity of the decision. We exploit that...

Using stagger charts to improve the accuracy of demand forecasts

Ramosaj, Agneta ; Widmer, Marino

(Internal working papers DIUF ; 20-01)

Nowadays, no business organization can avoid the need for accurate demand forecasting. It helps make the right decisions at every level, strategic or operational, and it is the center of financial simulation or procurement decisions in terms of production. A way to depict company forecasts could be provided by a stagger chart, a visual tool that is easy to implement and is understandable at...
