I don't know, overoptimistic real estate developers? My point is just that asserting that rents in SF are increasing because they are trying to reach some kind of equilibrium with Flint, MI obviously involves glossing over tons of factors that affect rents more in the short term. You might as well argue that rents in SF are rising because they are trying to reach equilibrium with the rents in rural villages in Mali

If developers in SF become too optimistic then those homes become a drag on the economy, and SF soon loses the career advantage it currently has, still leading to equilibrium eventually.

I felt I was quite explicit that finding equilibrium takes time. I am not sure why you are focusing on short term movements in price.

In some ways that is true. China's rags to riches story happened in large part due to costs in the US rising to the point where it became cheaper to move (some) operations over there. Reaching equilibrium at the international scale is more difficult due to many artificial barriers found along the way, however. There is really nothing stopping an American citizen living in SF from moving to Flint.
