SODAS Data Discussion 26 February 2021
Copenhagen Center for Social Data Science (SODAS), is pleased to announce that we are continuing with SODAS Data Discussions this spring.
SODAS aspirers to be a resource for all students and researchers at the Faculty of Social Sciences. We therefor invite researchers across the faculty to present ongoing research projects, project applications or just a loose idea that relates to the subject of social data science.
Every month two researchers will present their work. The rules are simple: short research presentations of ten minutes are followed by twenty minutes of debate. No papers will be circulated beforehand, and the presentations cannot be longer than five slides.

Title: Tell me a story: Quantifying economic narratives and their role during COVID-19
We provide quantitative evidence that economic narratives are deeply integrated with the real economy and financial markets. To that end, we retrieve the most salient COVID-19 narratives from daily open-ended questionnaires presented to a large number of US stockholders prior to, during, and after the first wave of the pandemic (February through June, 2020). We elicit thirteen narratives (e.g. supply disruption, investor fear, stay at home, infection worry, and fiscal and monetary policy intervention) using textual analysis from the survey responses and quantify their propagation over time with individual time series. These narrative series are then included in a large network of macro-financial vari- ables, revealing that (i) narratives significantly drive unexpected fluctuations in the real economy and financial markets and that (ii) narratives are themselves shaped by the real economy and financial markets. The two directions are generally equally strong. These effects exist at a daily horizon, and cumulate over a weekly and monthly horizon. Narratives on supply disruption, infection worry, consumer confidence, and fiscal policy intervention play a dominant role.

Title: Identifying the impact of scholar mobility using bibliometric data
The science of science literature suggests that scientists acquire different rewards for their work depending on their prior reputation. This means that scientists affiliated with high prestige institutions are often at an advantage compared to scholars from less prestigious institutions or lower research-intensive countries. However, it has previously been unknown whether this effect was due to differences in researcher quality (capacity) or due to a status-driven “Mathew-effect”. In the present study, we use scholarly mobility, as measured through the Web of Science bibliometric database, as a method to try and disentangle these potential explanations. We also aim to assess the impact of different international mobility choices on a researcher’s long-term scientific performance.
We will compare performance of scholars (using a difference-in-difference approach) by matching authors with similar backgrounds (using coarsened exact matching) to understand both the short-term and the long-term impact of mobility on scientists’ career development. By looking at the performance of international mobile researchers and that of their non-mobile peers, we can assess the priming effect that specific countries, or institutions, have on the external perception of their scientific output.
The SODAS Data Discussion will take place at SODAS in Zoom from 11.00 am to 12.00 noon.
