Some of my current projects:

• herd behaviour in firm location: does clustering really originate with rational choices and measurable advantages? (with two current students)
• following your job: when do employees follow their employer if the firm moves out to the periphery? (with Paula Prenzel)
• related variety: a meta-analysis (with Jeroen Content)
• regional gender gaps (with Frank van Oort)
• entrepreneurs in Amsterdam (with former student Harm-Jan Rouwendal)
• robustness of agglomeration measures (with Frank van Oort)
• co-working spaces (COST action, with Veronique Schutjens and others)
• measuring innovation using webscraping (with former student Jaap Willems)
