Coalition formation as a popularity contest?

In a new study, @wmjunk.bsky.social and I examine which groups are preferred partners in agenda setting. We find NGOs are favoured, and trusted allies trump capable newcomers—shaping how networks form and why NGOs hold an edge.

Does lobbying access actually mean lobbying influence?

In our new @jeppjournal.bsky.social paper we try to answer this key question in interest group politics and lobbying by exploring models of access = influence translation.

For those interested in Dutch politics:

Far-right leader, Geert Wilders, just pulled the plug on the government coalition that his party PVV was a part of.

May I add that this happened as his party was slipping in polls…

Geert Wilders PVV leaves Dutch government coalition, resulting in fall of cabinet Schoof

Thank you for sharing! This is very inspiring.

As I’ve stepped into more senior roles in academia (plus gotten a bit older), I often get asked:

“How do you keep writing academic articles, policy work, opinion pieces, while juggling everything else?”

My answer: skillpower
