Quantitative Analysis of Publication Bias, Impact Factors and Tools for Measuring (QUANT)

The aim of the project is to study the relation between bibliometric performance measurements and the prevalence of publication bias (PB),  i.e. a selective publication of statistically significant and/or hypothesis-conforming results). In the first step, we systematically analyse the correlation between PB and the impact factor of journals using data from psychology and economics. In the next  step, we analyse possible drivers of the revealed relationship, for instance caused by the citation bias, i.e. the disproportionately more frequent citation of significant results. Ultimate project aim is to develop a guideline for monitoring and prevention of PB.

Gender- and Class-Specific Job Preferences: Survey Experiments in Different Household Contexts



There is preliminary empirical evidence that persisting gender inequalities are at least partly rooted in a missing fit of job offers’ working conditions and institutional frames to individual preferences, and that this is particularly true from a couple and family perspective. So far these inequalities were only rarely theoretically modeled and empirically researched. Using an innovative experimental data set, the general aim of the proposed project is to analyze how institutional and organizational frameworks frame gender and class specific willingness to accept job offers, and how differences in preferences and willingness to make concessions relate to the division of labor in couples and families. How do gender inequalities intersect with a possible mismatch? What is the impact of flexible working hours or availability and regional distribution of child care facilities on gender and class specific labor supply? How do norms and earnings constellations within households become relevant? Would there be more or less inequality if institutional and organizational restrictions were removed, allowing more freedom of choice when realizing job preferences? For the empirical analysis, a factorial survey module will be used which the applicants have successfully implemented into the Innovation Sample of the Socio Economic Panel (SOEP-IS). This module enables a multidimensional measurement of the willingness to accept job offers considering multiple, theoretically motivated conditions for reconciling work and family responsibilities for the first time.
