The Household Finance and Consumption Survey (HFCS) provides information about household wealth (real and financial assets as well as liabilities) from 15 Euro‐countries after the financial crisis of 2007/8. The survey will be the central dataset in this topic in the future. However, several...

Der vorliegende Beitrag ist eine Metaanalyse von 99 deutschen Bevölkerungssurveys aus dem GESIS-Datenarchiv, in denen die postmaterialistische Einstellung der Befragten ermittelt wird. Es wird anhand von Mehrebenenmodellen gezeigt, dass sich der Anteil der Postmaterialisten unter Kontrolle von...

Im Jahr 2006 wurde erstmals ein Kognitionstest für Jugendliche in das Erhebungsinstrumentarium des SOEP aufgenommen und seitdem jährlich bei einer neuen Jugendkohorte durchgeführt. Ein speziell modellierter Fragebogen erfasst basierend auf dem I-S-T 2000-Test die fluiden...

Respondent driven sampling (RDS) is a network sampling technique typically employed for hard-to-reach populations (e.g. drug users, men who have sex with men, people with HIV). Similar to snowball sampling, initial seed respondents recruit additional respondents from their network of friends....

The paper analyzes factors that influence the adoption of e-learning and gives an example of how to forecast technology adoption based on a post-hoc predictive segmentation using a classification and regression tree (CART). We find strong evidence for the existence of technological...

Germany's water supply industry is characterized by a multitude of utilities and widely diverging prices, possibly resulting from structural differences beyond the control of firms' management, but also from inefficiencies. In this article we use Data Envelopment Analysis and Stochastic Frontier...

The German potable water supply industry is regarded as being highly fragmented, thus inhibiting high potentials for efficiency improvements through consolidation. Focusing on a hypothetical restructuring of the industry, we apply Data Envelopment Analysis (DEA) to analyze the potential...

We study the determinants of sovereign bond yield spreads across 10 EMU countries between Q1/1999 and Q1/2010. We apply a semiparametric time-varying coefficient model to identify, to what extent an observed change in the yield spread is due to a shift in macroeconomic fundamentals or due to...

Applying a method suggested by Woodruff (1971), we derive the sampling variances of Generalized Entropy and Atkinson inequality indices when estimated from complex survey data. It turns out that this method also greatly simplifies the calculations for the i.i.d. case when compared to previous...

In survival analysis, Cox's name is associated with the partial likelihood technique that allows consistent estimation of proportional hazard scale parameters without specifying a duration dependence baseline. In discrete choice analysis, McFadden's name is associated with the generalized...
