Adviser Connectedness and Placement Outcomes in the Economics Job Market, Labour Economics 84.
(2023).- We study the role of social networks in the academic job market for graduate students of Economics. We find that the connectedness of a student’s advisor in the coauthor network significantly improves her job market outcome. We use two identification strategies and find that a) higher Eigenvector centrality of an adviser leads to her student getting placed at a better ranked institution, and b) larger distance between an adviser and an institution decreases the probability that her students are placed there. Our study sheds light on the importance of social connections in a labour market where information frictions regarding job openings are virtually absent.

Discussants, Research Policy, 51 (10). DOI
(2022).- We study the role of informal collaboration in academic knowledge production using published research papers previously presented and discussed at the NBER Summer Institute. We show that papers that have a discussant are published in highly-ranked journals and are more likely to be published in a top journal. Conditional on having a discussant, the quality of a paper’s journal outlet increases in the discussant’s prolificness and editorial experience. This supports the idea that discussants help reduce information asymmetries that are inherent in the academic publication process. Conversely, using social network analysis we find no evidence that citations accumulate because discussants diffuse information about the paper.

The Rise of Multiple Institutional Affiliations in Academia, Journal of the Association for Information Science and Technology, 72 (8), 1039-1058. DOI
(2021).- This study provides the first systematic, international, large-scale evidence on the extent and nature of multiple institutional affiliations on journal publications. Studying more than 15 million authors and 22 million articles from 40 countries we document that: In 2019, almost one in three articles was (co-)authored by authors with multiple affiliations and the share of authors with multiple affiliations increased from around 10% to 16% since 1996. The growth of multiple affiliations is prevalent in all fields and it is stronger in high impact journals. About 60% of multiple affiliations are between institutions from within the academic sector. International co-affiliations, which account for about a quarter of multiple affiliations, most often involve institutions from the United States, China, Germany and the United Kingdom, suggesting a core-periphery network. Network analysis also reveals a number communities of countries that are more likely to share affiliations. We discuss potential causes and show that the timing of the rise in multiple affiliations can be linked to the introduction of more competitive funding structures such as "excellence initiatives" in a number of countries. We discuss implications for science and science policy.

What 5,000 Acknowledgements Tell Us About Informal Collaboration in Financial Economics, Research Policy, 50 (6). DOI
(2021).- We present and discuss a novel dataset on informal collaboration in financial economics, manually collected from more than 5,000 acknowledgement sections of published papers. We find that informal collaboration is the norm in financial economics, while generational differences in informal collaboration exist and reciprocity among collaborators prevails. Female researchers appear less often in acknowledgements than comparable male researchers. Information derived from networks of informal collaboration allows us to predict academic impact of both researchers and papers even better than information from co-author networks. Finally, we study the characteristics of the networks using various measures from network theory and characterize what determines a researcher’s position in it. The data presented here may help other researchers to shed light on an under-explored topic.

Adviser Connectedness and Placement Outcomes in the Economics Job Market, Max Planck Institute for Innovation & Competition Research Paper, No. 18-12.
(2023).- Using two identification strategies, we show that the connectedness of a PhD adviser (in the coauthor network) positively affects the placement of her student. First, we demonstrate that, on average, more central advisers place their students at better ranked institutes. To do this, we use the changes in the centrality of the adviser's coauthors in the year of student placement as an exogenous shock to the adviser's centrality. Our second strategy uses the death of faculty members as an exogenous shock to show that the probability of a student being placed at a particular university reduces when the 'social distance' between her adviser and that university increases due to the death.

Logic Mill - A Knowledge Navigation System, arXiv preprint 2301.00200.
(2022).- Logic Mill is a scalable and openly accessible software system that identifies semantically similar documents within either one domain-specific corpus or multi-domain corpora. It uses advanced Natural Language Processing (NLP) techniques to generate numerical representations of documents. Currently it leverages a large pre-trained language model to generate these document representations. The system focuses on scientific publications and patent documents and contains more than 200 million documents. It is easily accessible via a simple Application Programming Interface (API) or via a web interface. Moreover, it is continuously being updated and can be extended to text corpora from other domains. We see this system as a general-purpose tool for future research applications in the social sciences and other domains.

Allegations of Sexual Misconduct, Accused Scientists, and Their Research, Max Planck Institute for Innovation & Competition Research Paper, No. 22-18. DOI
(2022).- We study academic consequences of non-academic misconduct for accused researchers at US universities. Focusing on allegations of sexual misconduct, we find detrimental effects on scientific impact, productivity and career. Other researchers are less likely to cite the perpetrator’s prior work after allegations surface. The effect is absent in male-dominated fields and weakens with distance in the co-authorship network, indicating that researchers learn about allegations via their peers. Although we find that alleged perpetrators tend to remain active researchers, they are less likely to be affiliated with a university and publish fewer articles following the incident.

(2022). #ScienceForUkraine: an Initiative to Support the Ukrainian Academic Community. “3 months since Russia’s invasion in Ukraine”, February 26 – May 31,- here was an immediate ad-hoc response of the international scientific community to help scholars from universities affected by Russia's war in Ukraine. Official government-backed funding programmes later allowed the ad-hoc help offers to be sustainable and stable. The #ScienceForUkraine initiative is a grass-root initiative that emerged out of the desire to help; initially created as a central database for the worldwide offers for help. Its 133 active volunteers engaged with policy-makers and funding bodies to improve support to the Ukrainian academic community.
The website scienceforukraine.eu became a central and well-known hub with a general database for help listings but also extensive curated link lists for further help. There were more than 120k visits in the past three months, 12k of which are reportedly from Ukraine. #ScienceForUkraine has many active country groups that flexibly respond to needs in their geographic area. Collecting information, creating posters for border stations, mentoring, consulting on how to organise transfers, and engaging with policy makers are some of the tasks performed by members.
#ScienceForUkraine is active on all major social networks to be in touch with both the Western academic community (primarily Twitter and LinkedIn) and the Ukrainian academic community (mainly Facebook and Telegram); whereas students are reached mostly via Instagram. The initiative fulfils an important function by transmitting information from one sphere to the other. #ScienceForUkraine recorded well over 2,600 support listings (one listing may be directed at several scholars). 15% of these were offered by German institutions (410), followed by French (227) and Polish (183) institutions. - Available at SSRN
Small World: Narrow, Wide and Long replication of Goyal, van der Leij and Moraga-González (JPE 2006) and a Comparison of EconLit and Scopus, Max Planck Institute for Innovation & Competition Research Paper, No. 21-01. DOI
(2020).- I undertake a narrow, wide and long replication of Goyal, van der Leij and Moraga-González (Journal of Political Economy 2006; 114(2): 403–412). Using social network analysis they show that the Economics profession gradually evolved into a small world. Small worlds (or small world networks) have unique information transmission capabilities. The trend is explained by the emergence of frequently publishing researchers with many distinct co-authors. In a social network they resemble stars. The original results are robust to the usage of (I) another software, (II) a recent version of the originally used data, and (III) another database and a more sophisticated author disambiguation.

Finding Doppelgängers in Scopus: How to Build Scientists Control Groups Using Sosia, Max Planck Institute for Innovation & Competition Research Paper, No. 20-20. DOI
(2020).- The construction of control groups of scientists is often a daunting effort. This paper presents sosia, an open-source Python-based software designed to query efficiently the Scopus database via RESTful API. sosia searches for researchers with publication profiles similar to a given researcher up to a given year based on all main standard bibliometric indicators. The user can choose flexibly a set of parameters to restrict the search to more or less narrow boundaries upfront and obtain additional similarity indicators to select a subset of authors after the search. Advanced settings also allow to narrow the search to a list of affiliations and to minimize the possible errors arising from ambiguous author profiles. One basic search can be set up in a few command lines and the average time of computation goes between 60 and 300 minutes. We discuss the functioning, characteristics, limitations and possible extension of the software.
The Rise of Multiple Institutional Affiliations, arXiv preprint 1912.05576.
(2019).- The affiliation to an institution provides prestige and identity to researchers and determines access to resources and infrastructure. Institutions in turn seek to affiliate researchers to secure their knowledge and skills, benefiting the research conducted within these institutions and their position in national and international rankings. This study documents the phenomenon of researchers having multiple affiliations and discusses potential causes and consequences. We analyze affiliation information of 8.5M authors from 40 countries, who published 8.9M scientific articles in 14 disciplines since 1996. We find that multiple affiliations occur both within countries as well as across borders, and that more than 60% are within the academic research sector. The share of authors with multiple affiliations increased substantially over the past two decades and particularly since the mid-2000s. The increase is particularly pronounced in countries whose funding structures became more competitive. The rise of multiple affiliations points to fundamental changes in the organisation of science and challenges our measurements of where scientific activity takes place.

Informal Intellectual Collaboration with Central Colleagues, Kiel Working Paper, 2084.
(2017).- When preparing a research article, academics engage in informal intellectual collaboration by asking their colleagues for feedback. This collaboration gives rise to a social network between academics. We study whether informal intellectual collaboration with an academic who is more central in this social network results in a research article having higher scientific impact. To address the well-known reflection problem in estimating network effects, we use the assignment of discussants at NBER summer institutes as a quasi-natural experiment. We show that manuscripts discussed by a discussant with a 10% higher than average Bonacich centrality rank results in 1.4% more citations and a 5% higher probability that an article is published in a top journal. To illustrate our results, we develop a structural model in which a positive externality from intellectual collaboration implies that collaborating with a more central colleague results in larger scientific impact of the research article.
