Research projects and data

Organizational inequalities

Project period: 2015 -

The aim of this project is to study inequality in earnings and work careers in organizations in developed economies.

This project is a collaboration of researchers from 14 countries within the Comparative Organizational Inequality Network. We focus on forms of categorical inequality based on gender, race/ethnicity, age, etc, document their magnitude, and provide explanations linked to developments in work organizations. Within the larger project, I lead a team focusing on inequalities between sexual majority and minority employees.

The consequences of flexible employment

Project period: 2014 -

The aim of this project is to describe and explain the consequences of flexible work arrangements and contingent employment for workers and organizations using the Sustainable Workforce Survey, a novel multilevel organizational survey dataset. Within this research, I integrate individual, organizational, and national policy levels to better understand the causes and consequences of flexible work arrangements and contingent employment for workers' well-being and performance.

Economic, Institutional, and Political Development and Intergenerational Social Mobility in Hungary between 1850 and 2005

Doctoral dissertation project
Project period: 2009 - 2014

In this project, I studied changes in intergenerational social mobility over time and its macro-level economic and political determinants in Hungary using church marriage registers from a sample of municipalities between 1850 and 1950, and social stratification surveys up until 2005.

The Hungarian Historical Social Mobility File

Project period: 2009-2011

The Hungarian Historical Social Mobility File is a large-scale micro and macro level database of digitized historical marriage registers from Hungary collected as part of the Towards Open Societies research project of the Utrecht University. The database contains around 82.000 marriage records, registered between 1850 and 1950 in Hungary. Records contain the occupational information of the spouses, their parents, and the witnesses, information on the age of marriage, birthplace, and residence of the spouses and their parents. This database has the following unique features which make it valuable for historical sociological and demographic research.

1. Uniquely among historical micro-level data collection projects, we used a probability sample to select the localities in which church marriage records were digitized. The sampling frame covers all regions and municipalities of the territory of present-day Hungary. 66 towns and villages were selected, and books from every local parish were recorded, from all denominations.

2. The database contains information from all large regions of Hungary and represents municipal size and grade of industrialization within these regions. Regional and municipal level cross-sectional and time-series comparisons are possible with the data.

3. Municipal-level aggregate time series of population size and other demographic and industrial characteristics complement the marriage records, extracted from Hungarian censuses and other sources since the 1850s. The file is also supplemented with weighting schemes to the microdata which adjusts to the regional and municipal population size in different periods.

A short description of the sampling method and a table with sample size per municipality and denomination and father-to-son mobility data in aggregate mobility tables (country-level, 5-year marriage cohort periods) are open access (see download links below). Individual-level data are available upon request.
