Non-technical articles written for general audiences

The Puzzling Persistence of Place
Business Review 2015 Q2: 1-8. 

I explore the remarkable persistence of urban development patterns over decades, centuries, or even millennia. Is such extreme persistence desirable? What does it imply about today's "place-making" policies?

The Paper Trail of Knowledge Transfers
Business Review 2014 Q2: 1-6

Why do firms tend to locate near other firms? Economists suspect that geographic clustering spurs innovation by letting businesses tap a climate rich in informal transfers of knowledge. By tracing links between inventors filing for patents for the same inventions, I review new evidence supporting the idea that proximity offers businesses tangible benefits.

Geography, History, Economies of Density, and the Location of Cities
Business Review 2012 Q3: 18-24.

What determines the location of cities? I review evidence on the roles of natural amenities, history dependence, and economies of density in explaining the the location and sizes of cities.

Urban Productivity Advantages from Job Search and Matching
Business Review 2011 Q1: 9-16

Why do workers earn higher wages in big cities? One intriguing hypothesis is that agglomeration economies from job search and matching contribute to higher productivity in densely populated areas. I describe recent evidence and ask whether advantages from job search and matching are large enough to offer meaningful explanations for differences in productivity across cities.
