Weiterbildungsaktivitäten gelten als schwer erinnerbare Ereignisse. Daher wurde bislang auf die retrospektive Erhebung nicht-formaler und informeller Weiterbildungsaktivitäten weitgehend verzichtet. Im Rahmen der IAB-Studie 'Arbeiten und Lernen im Wandel (ALWA)' stehen jedoch auch kurze und...

Paneldaten haben gegenüber Querschnittsdaten zahlreiche Vorteile. Amtliche Daten sind zudem eine wichtige Quelle für die Sozial- und Wirtschaftswissenschaften. Viele amtliche Datenerhebungen sind als Panel konzipiert und durchgeführt oder können zu Panels zusammengefügt werden. Diese Arbeit...

We compare two alternative mixed mode survey designs with face-to-face data collection in terms of differences in estimates. Both mixed mode designs involve face-to-face, telephone and web interviewing. One design uses modes sequentially; the other offers respondents an explicit choice of mode....

We examine the effects on survey estimates of extended interviewer efforts to gain survey response, including refusal conversion attempts and attempts to make contact with hard-to-contact sample members. Specifically, we update and extend the research of Lynn & Clarke (2002). We estimate bias...

We assess whether the probability of a sample member participating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally...

Pre-election polls sometimes fail to reach the purpose for which they are carried out: to provide accurate predictions of electoral out-comes. By looking at the 2006 Italian General Elections, this paper aims to assess the role that different factors play in determining the accuracy of the...

It is common practice to adapt the format of a question to the mode of data collection. Multi-coded questions in self-completion and face-to-face modes tend to be transformed for telephone into a series of 'yes/no' questions. Questions with response scales are often branched in telephone...

In the UK, in order to link individual-level administrative records to survey responses, a respondent needs to give their written consent. This paper explores whether characteristics of the respondent, the interviewer or survey design features influence consent. We use the BHPS combined with a...

We conduct two large-scale randomised experiments on the British Household Panel Survey (BHPS) to study methods of reducing panel attrition. The first experiment compares different strategies for tracing and maintaining contact with sample members. We find that change-of-address cards...

In face-to-face surveys interviewers play a crucial role in making contact with and gaining cooperation from sample units. While some analyses investigate the influence of interviewers on nonresponse, they are typically restricted to single-country studies. However, interviewer training,...
