Constructing Joint ConfiDence Bands for Impulse Response Functions of Var Models: A Review

Methods for constructing joint confidence bands for impulse response functions which are commonly used in vector autoregressive analysis are reviewed. While considering separate intervals for each horizon individually still seems to be the most common approach, a substantial number of methods have been proposed for making joint inferences about the complete impulse response paths up to a given horizon. ...

Structural Vector Autoregressive Models with more Shocks than Variables Identified via Heteroskedasticity

In conventional structural vector autoregressive (VAR) models it is assumed that there are at most as many structural shocks as there are variables in the model. It is pointed out that heteroskedasticity can be used to identify more shocks than variables. However, even if there is heteroskedasticity, the number of shocks that can be identified is limited. A number of results are provided that allow ...

The Need for Household Panel Surveys in Times of Crisis: The Case of SOEP-CoV

The spread of the novel coronavirus, SARS-CoV-2, poses major challenges for individuals and societies at large. The question now is how individuals and society are dealing with these challenges, and what health, psychological, social, and economic effects they will have to bear. Meaningful answers can only be provided using a generalizable database that contains contextual information such as family ...

Multiple Imputation of Binary Multilevel Missing Not at Random Data

We introduce a selection model‐based multilevel imputation approach to be used within the fully conditional specification framework for multiple imputation. Concretely, we apply a censored bivariate probit model to describe binary variables assumed to be missing not at random. The first equation of the model defines the regression model for the missing data mechanism. The second equation specifies ...

Using Mathematical Graphs for Questionnaire Validation

We present an approach for studying three quality issues related to survey data, namely the detection of interviewer misbehaviour, the correct implementation of the questionnaire programming and possible redundant paths, which lead to case numbers hindering feasible statistical analysis. The idea is using a theoretical graph model for describing all possible paths through...

Self-Control: Determinants, Life Outcomes and Intergenerational Implications

This paper studies self-control in a nationally representative sample. Using the wellestablished Tangney scale to measure trait self-control, we find that people’s age as well as the political and economic institutions they are exposed to have an economically meaningful impact on their level of self-control. A higher degree of self-control is, in turn, associated...

Comparing Self-Reported and Partnership-Inferred Sexual Orientation in Household Surveys

Research comparing heterosexuals with bisexuals and homosexuals in economics and the social sciences typically relies on two strategies to identify sexual orientation in existing survey data of general populations. Probing respondents to self-report their sexual orientation is generally considered the preferred option. Since self-reports are unavailable in most large multidisciplinary surveys, often ...

Paneldaten für die Sozialforschung

Unter Paneldaten versteht man im Bereich der empirischen Sozialforschung Daten auf Basis einer Untersuchungsanlage, bei der gleichzeitig drei Merkmale erfüllt sind. Es werden bei denselben Untersuchungseinheiten dieselben oder zumindest die gleichen Inhalte erhoben und die Daten werden mehrfach, also mindestens zweimal ermittelt.
