Urban Economics 8
Consider the Dinks (double income, no kids). Mr. Dink commutes to a job in the city center (x=0), while Ms. Dink commutes to a suburban subcenter four miles east of the city center. The Dinks consume the same quantity of housing at all locations. Travel speed is the same in both directions. a . Draw
