Understanding the origins of policy ideas can be crucial when trying to explain dynamics of political change and continuity. Paradigmatic changes in the German pension system have been attributed to the import of “foreign” neoliberal policy ideas from transnational organizations and other countries. The literature describes such processes as policy diffusion, transfer, or translation. In contrast, this article argues that foreign pension ideas did not have a substantive influence on local policy innovations and preference-formation processes. Instead, pension policy pioneers developed their ideas predominantly “from within” through bricolage by reconfiguring long-standing domestic schools of thought. Drawing on a wide range of primary and secondary sources, the analysis combines a broad historical perspective with case studies of individual policy makers. This sheds new light on the careers of ideas and why significant actors pick them up at certain points.
