New Research Fellow Jacob Habinek


We are delighted that the IAS-team is steadily growing. From October 1, we are happy to welcome our new Research Fellow Jacob Habinek.

Jacob got his PhD in sociology at the University of California, Berkeley, in 2016, and then spent two years in the Sociology of Markets research group at the Max Planck Institute for the Study of Societies in Cologne, Germany.

At IAS he will use computational text analysis and network analysis to explore how networks of social influence can explain the emergence and evolution of new organizations and markets. He has two ongoing research projects at the moment, one on the emergence of academic disciplines and the other on strategies of speculative investment in securities markets.

Grant for research of segregation


We are proud to announce that Formas has awarded a new grant to Benjamin Jarvis and Sarah Valdez of IAS, along with their collaborators Guilherme Chihaya of Umeå University and Simone Scarpa.

Their project, “The Segregating Effects of Market and Non-Market Housing Allocation Mechanisms”, will examine how public housing queues and policies which promote homeownership influence patterns of ethnic segregation. The project will run from 2019-2021.

New PhD students at IAS


We are happy to welcome our two new PhD students at IAS, Miriam Hurtado Bodell and Emanuel Wittberg. 

Miriam got her master’s degree in statistics at Linköping University in 2014 and has previously attained bachelor’s degrees in both political sciences, majoring in economics, and statistics from Uppsala university. Her main interests are in using computational text analysis to understand political processes and discourse and causal inference. Prior to her current position, Miriam worked as a data analyst/research assistant at the Institute for International Economic Studies in Stockholm.

Emanuel’s position is the result of a collaboration with Centre for Municipality studies at the Department for studies of Social Change and Culture. Emanuel will conduct research about corruption and corruption risks in developed welfare states, with special focus on the municipality level in Sweden. He will explore how an analytical approach with focus on mechanism-based explanations can be integrated into classical corruption research which traditionally is built on the rational choice theory. Prior to his current position, Emanuel has worked as research assistant in projects connected to the study of corruption risks related to New Public Management reforms in Sweden. Apart from this, he has a background in the field of economics in which he has a master’s degree.

Opinion piece about voucher schools and segregation

Crowd wisdom among voters


Marc’s follow-up on crowd widsom has been published in Advances in Complex Systems. The authors, Christian Ganser (LMU Munich) and Marc Keuschnigg (IAS), demonstrate in agent-based simulations that under voting social influence contributes to information aggregation and thus strengthens collective judgment. This result stands in stark contrast to the effects of social influence on averaging---the highly researched yet infrequently used social decision rule---for which many have said that social influence narrows the variation in individual opinions and thus undermines crowd-wisdom effects. Understanding the consequences of social learning through these types of studies holds important ramifications for the design of collective decision-making in both public administration and private firms.

New study on trailing spouse phenomenon


IAS professor Magnus Bygren was interviewed in Dagens Nyheter on new study. The study investigates whether employer choices contribute to the so-called trailing spouse phenomenon, that couples tend to relocate for the sake of the man’s career rather than the woman’s. The study´s findings indicate that employers favor geographically distant men over geographically distant women, indicating that employer recruitment choices do contribute to the trailing spouse phenomenon by offering men a larger pool of geographically distant jobs.

New study on wage dispersion and cross-firm mobility


Chanchal Balachandran, Linköping University, Sweden and Aleksandra Kacperczyk, London Business School, United Kingdom recently published an article entitled “Vertical and Horizontal Wage Dispersion and Mobility Outcomes: Evidence from the Swedish Microdata.” The article was published in Organisation Science, February 22, 2018.

The article highlights the relationship between wage dispersion and cross-firm mobility. The authors propose that the effect of wage dispersion depends on organizational rank and whether wages are dispersed vertically (between job levels) or horizontally (within the same job level).

The result shows that that vertical wage dispersion suppresses cross-firm mobility because it is associated with outcomes beneficial for employees, such as attractive advancement opportunities. By contrast, horizontal wage dispersion increases cross-firm mobility because it is associated with outcomes harmful for employees, such as inequity concerns.

Analytical sociology and computational social science


In the new Journal of Computational Social Science, Marc Keuschnigg, Niclas Lovsjö, and Peter Hedström highlight the mutual benefits between Computational Social Science (CSS) and Analytical Sociology (AS): By providing relevant analytical tools to rigorously address sociology’s core questions, CSS has the potential to advance sociology in a similar way that the introduction of econometrics advanced economics during the last half century. For the nascent field to reach its full potential, they outline how AS can help to move CSS forward from descriptions and predictions to the explanation of social phenomena.

Two IAS’ researchers receive prestigious grants from the Swedish Research Council


We are proud to announce that two of our researchers has received prestigious three-year grants from the Swedish Research Council.   

The project titled “Understanding the dynamics of school choice to reduce segregation in education”, by Eduardo Tapia, aims to contribute to the analysis of the causes of school segregation in Sweden. On the basis of the implementation of a large-scale empirically-calibrated ABM on school choice using Swedish population registers, the project pursues three main objectives: (a) the study of students’ preferences on schools, (b) the analysis of the cumulative effect of students’ choices on segregation, and, finally, (c) the impact assessment of the current and alternatives admission school procedures on segregation.

The other project, called “Grading Practices and Inequality of Opportunity”, by Anders Hjorth-Trolle, studies the effects of school grading and grading practices on social stratification. In 1997, the Swedish education system changed their grading practice from relative grades (where teachers assess students' skills in relation to their peers) to absolute grades (where teachers base their grades on specific criteria for each course). This project will analyze how such a change in grading practice affects a student's grades differently depending on their ethnicity and their parents' socioeconomic status and how grades matter for later life outcomes such as earnings, education, and health. The project will compare its findings with data from Denmark, a comparable welfare state, which recently instituted similar reforms.

New evidence on the low-cost hypothesis

Marc Keuschnigg, assistant professor at IAS, shows in a natural experiment how normative change affects the relationship of attitudes and behavior.

This relationship has often been described in terms of the "low-cost hypothesis:" Attitudes and behaviors correspond in situations of little inconvenience, but diverge as choosing the "right" option requires greater effort. Through the example of household waste recycling, the authors demonstrate that the scope conditions of the "low-cost hypothesis" include only actions for which compliance-enforcing social norms are weak. This finding, now published in Environment and Behavior, reconciles prior results from the environmental social sciences.

IAS researcher Christian Steglich receives prize for software rSiena


This year, at the Beijing Sunbelt Conference, a committee of judges consisting of Vlado Batagelj, Alessandro Lomi, and Jim Moody, has awarded the Richards Prize to rSiena.
Together with Tom A.B. Snijders (University of Groningen and University of Oxford), Christian Steglich at the Institute for Analytical Sociology has been the main developer of the software. Our warmest congratulations!

The William D. Richards Software Award is a "lifetime achievement award" to honor individuals who have created publically available social network analysis software without which it would be impossible to study social networks. Named in honor of former INSNA President Bill Richards, the award is a biennial prize. The award has three purposes: it recognizes breakthrough thinking in developing social network analysis software that becomes highly valued by the scholarly community; it acknowledges the longevity of the software, as its functionality evolves in close correspondence with changes in the field of social network analysis; and, finally, it honors the dedication of the scholars in providing this service to the community. 

IAS researcher Marc Keuschnigg receives prestigious price for best paper in Analytical Sociology


Robert K. Merton was one of the most influential sociologists of the 20th Century. His writing on the principles and importance of middle-range theory as well as his own theories of self-fulfilling prophecies and Matthew effects have been important sources of inspiration for the emergence of analytical sociology. The Robert K. Merton Award for the best paper in analytical sociology is an annual award announced at the annual INAS conference. The award is based on a thorough selection process. Nominations are sought from the international scholarly community and the decision is made by a committee of leading scholars appointed at the INAS meeting. The 2017 Robert K. Merton Award was bestowed on the article "Disorder, social capital, and norm violation: Three field experiments on the broken windows thesis", written by Marc Keuschnigg and Tobias Wolbring. It was published in Rationality and Society, 2015.


Is Category Spanning Truly Disadvantageous?

IAS researcher Marc Keuschnigg and Thomas Wimmer present new evidence from primary and secondary movie markets in new article in Social Forces


Genre assignments help audiences make sense of new releases. Studies from a wide range of market contexts have shown that generalists defying clear mapping to established categories suffer penalties in market legitimacy, perceived quality, or audience attention. The data used in the study on feature films released to US theaters and subsequently made available on DVD reveal that consequences of category spanning are subject to strong moderating influences. Negative effects are far from universal and the study provides ramifications as to the scope conditions of categorization effects and modifies some widely acknowledged truisms regarding boundary crossing in cultural markets.

IAS researchers show that impact of school segregation on performances is overstated


Policy makers, school administrators and parents have drawn the conclusion that ethnic segregation impedes the education progress of both native born and immigrant studies. IAS researchers Maria Brandén and Gunn Birkelund and former IAS researcher Ryszard Szulkin studied data from students between 1998 and 2012 and the results show that the influence of the ethnic composition of classrooms on educational performance was close to zero.

Random allocation is better than proximity and queuing time in countering segregation.


The free school choice has contributed to increased school segregation. Selection based on queuing time is probably one contributing explanation. Random allocation of pupils to schools will not automatically lead to more mixed schools, but the method offers better prospects of countering segregation than the alternatives. The method is simple, transparent and provides equal chances to all applicants, write 20 school researchers, among them Peter Hedström, professor and director of IAS.

Article in Social Science Research

In a recent publication in Social Science Research Marc Keuschnigg, together with colleagues from LMU Munich,Felix Bader and Johannes Bracher, shows how global crowdsourcing platforms such as Amazon’s Mechanical Turk can be adapted to estimate effects of local context in behavioral games.
Marc KeuschniggBringing context back into social experiments is particularly relevant for sociological research which-unlike most experimental research in economics and psychology-fully acknowledges the importance of context effects in a multi-level explanation of individual action.
