While there is much new, Paper Picnic 2.0 remains committed to simplicity: no alert chaos, no registration, no clutter. Curious about the details? Read more on the Paper Picnic Substack: substack.com/home/post/p-....
The refurbished website gives you more control over what you see: toggle journal visibility and drag and drop to reorder journals. There is now also a dark mode 😎 and you can export BibTeX citations for new papers directly to your clipboard 📋(and from there to your reference manager).
Working papers from SocArXiv (osf.io/preprints/so...) and OSF Preprints (osf.io/preprints) are now integrated directly into the main site. Make sure to submit your working papers in the category “Social and Behavioral Sciences” to appear on Paper Picnic.
We now cover 142 journals — the top 20% of political science journals (N=70) and the top 5% of journals in adjacent fields. To rank journals, we used the Journal Citation Reports’ Article Influence Score.
🧺 Paper Picnic 2.0 is here! More journals. New features. An easier way to keep up with the latest research in political science and adjacent fields. 🧵👇
What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma.
It's *scientific publishing*.
We call this the Drain of Scientific Publishing.

We demonstrate that there is a compositional effect: using survey data, we show that leavers were 18 pp less likely to support the incumbent than stayers. Thus, in constituencies with more out-migration, the incumbent vote share increased.
Using constituency-level electoral data, we show that in East German constituencies with more out-migration between 1990–1994, the incumbent vote share increased. What explains this? Do voters reward the incumbent for high out-migration (sparked by increasing unemployment)? Unlikely.
To illustrate the formal results, we study the case of East Germany after reunification, when more than 9% of East Germans moved to former West Germany. How did this exodus affect electoral support for the incumbent coalition government in the 1994 federal election across East Germany?
These two types of effects are conceptually similar but different to natural (in)direct effects in mediation analysis. We discuss how to identify, estimate, and bound the compositional effect from in- and out-migration.
We use Rubin's potential outcomes framework to formally define compositional effects and to decompose the total causal effect of internal migration into exposure effects and compositional effects.
When studying how internal migration affects changes in district-level electoral outcomes, it is important to separate the compositional effect (heterogeneity in political behavior between movers and stayers) from the exposure effect (change in political behavior due to exposure to migration).

I have been attending EPSA since 2014, but I’m excited to attend EPSS in Belfast next year instead. Below some clarification how EPSS differs from EPSA.
The European Political Science Society is now accepting paper & panel proposals for its annual conference!
📢 Call for Papers: EPSS 2026 – Belfast
🗓️ June 18–20, 2026
📍 ICC Belfast
📬 Deadline: Nov 7, 2025

🚨 Big News for European Political Science 🚨
We’re thrilled to announce the launch of the European Political Science Society (EPSS): a new, member-led, not-for-profit association built to support our scholarly community.

Here’s a thread with everything you need to know.

Und wohin geht dann die Erststimme?
Das Wählerverzeichnis ist in der Verantwortung des Kreiswahlleiters und nicht des Bundeswahlleiters. Es gibt also nicht 1 WZ in D. Wählen (persönlich und per Brief) kann man daher auch nur im jeweiligen Wahlkreis weil nur dort die Registrierung der Stimmenabgabe im WZ möglich ist.
A few months actually. Launch date was August 23, 2024.

Working paper: osf.io/preprints/so... Research brief: immigrationlab.org/project/prep...
6/ For policymakers preparing for future refugee arrivals, this research highlights the need to balance urgency, capacity, & effectiveness in integration programming. Scaling existing, proven programs may be more effective than building large-scale initiatives from scratch.
5/ The limited number of classroom hours (320 vs. 600 hours), a non-standardized curriculum, and a lack of certification might explain the differences between the two programs.
4/ But the pre-existing program did help refugees to secure jobs! Using a staggered difference-in-differences design, we find that participants were 4.4 percentage points more likely to be employed after just 1 year of starting the course, rising to 12 p.p. after 18 months.
3/ Using a regression discontinuity design, we compare refugees who arrived in Germany before and after the eligibility cutoff for the ad hoc program, observing refugee employment outcomes over nearly 2 years. We find that the ad hoc program had no impact on employment.
