Hello! I'm an economist studying cities, regions, and growth. I'm interested in how and why places change, especially over long time scales.

Some of my current research projects are on self-fulfilling expectations in neighborhood development, central neighborhood decline in the mid-20th century, & long-run invention dynamics.

Some hats that I wear:
* VP & economist, #PhilFedResearch.
* Co-host, #DenselySpeaking podcast.
* Co-editor, #RSUE.
* Co-director, Philadelphia #FSRDC.
