In the recent ‘Regional outlook’, the OECD (2014) convincingly argues that cities can be the drivers of national growth and recovery: in principle, their diversity and density makes people and companies more productive and innovative. This is not only a tale of large cities: over the last decade, as recent studies demonstrate (e.g. Dijkstra, 2013) many smaller and medium-sized cities across Europe were important economic engines. But this did not happen automatically: to make that happen, ‘getting cities right’ is the key challenge, and action on the city level matters! As demonstrated by recent OECD data (OECD, 2014), poorly organised cities fail to reap their economic potential.
