Jane Jacobs was a fascinating thinker, economist, urban studies and public policy theorist. Her work addresses the growth of cities and their economies.
Here are some interesting ideas she poses in her work The Economy of Cities.
Why adding new work to old work is crucial to growing an economy (instead of merely dividing existing work more)
Why loosely structured and inefficient economies are better suited to survive change.
Why cities predated agriculture as we know it.
How cities can replace imported goods with their own industries.
Why some villages grow into cities and some do not.
How the design of urban spacies can either promote order or hinder it.
If you are studying urban studies, public policy or economics you need to read her.
For some reason, she has two entries in the catalog. One here, the other here.
