One of the big questions in urbanism is the degree to which culture shapes economic development. Traditionally, it was thought that culture follows from economic development: The more developed and affluent that a city becomes, the more money that it has to spend creating art galleries, museums, concert halls, and other cultural venues.
But my own writing on the creative class and a large number of other studies argue that culture acts as a key factor in economic development by helping attract talented, ambitious people to cities. Others go further, contending that arts and culture are large industries that act as direct inputs into development.
