The Policy Studies Journal (PSJ) invites submissions for a special Issue focusing on policy diffusion. Since Walker’s groundbreaking work 65 years ago, policy diffusion research has both burgeoned and stagnated at times (Mooney 2021). It continues to be a key policy process theory that has experienced significant advancements in the last decade in data (Boehmke et al. 2020), methods (e.g., Linder et al. 2020), theory (e.g., Colvin and Jansa 2024), and broadening from the American federal context (e.g., Cao 2010, Zhang and Zhu 2019).
This special issue invites papers that engage on any of the four fronts listed above: data, methods, theory, and context. Importantly, the aim is not to publish studies of a single policy using conventional methods (e.g., Event History Analysis) that confirm existing theory. We are looking for work that continues to push the boundaries of policy diffusion research. Papers should aim to explain diffusion broadly and should only focus on a single policy if it is a unique case that illustrates the boundaries of existing theory. These could include papers that:
- Provide methodological and/or theoretical advancements on our specification and understanding of the key mechanisms of diffusion.
- Explore diffusion dynamics in contexts beyond the American federal system and Europe. These could be new within-country contexts or underexplored regions like Africa.
- Propose new methods for conducting diffusion research.
- Link the macro-level patterns most commonly observed in diffusion studies (e.g., number and timing of adoptions) with the micro-level behavioral foundations that are assumed to be generating those patterns.
- Builds bridges between policy diffusion and other major policy process theories.
- Make greater use of the State Policy Innovation and Diffusion (SPID) database (https://dataverse.harvard.edu/dataverse/spid).
We also invite shorter pieces (3,000 – 5,000 words), including those that wrestle with the translational and practical implications of policy diffusion research for policymaking and governance. These will be published together in Policy Theory & Practice (a rolling special issue associated with PSJ) and will be bound with the PSJ special issue through our editorial introduction. This allows us to leverage all opportunities offered by PSJ to advance our thinking about policy diffusion.

**The deadline for submitting a manuscript for the Special Issue is December 1, 2025**
Potential contributors to the Special Issue may participate in a “Peer Paper Exchange” in the spring of 2025, through which authors can obtain informal feedback from peers who also plan to submit a paper to the Special Issue and opt to participate in the Exchange. For the exchange, papers will be paired together so the authors can exchange and provide each other with feedback. It is not a formal workshop. Participation in the exchange is intended to support the development of papers but has no bearing on the peer review process that will be undertaken by PSJ once papers are submitted to the journal. That review process is formal and entirely independent of the Peer Paper Exchange.
To participate in the Peer Paper Exchange, please submit a one-page abstract that explains your research question, the contribution of your research to policy diffusion, and the data and methodological approaches you plan to use to answer your research question, along with the paper title and author information. This is due by April 1st. Notifications of acceptance to participate in the Peer Paper Exchange will be made by May 15th.
Authors participating in the Exchange must share their draft papers with fellow participants by September 1st. Comments from the Exchange review will be returned to the authors by October 1st.
