Rent Control and Elasticity Consider the effects of rent control in two cities, each of which imposes rent control with a maximum price of $400, compared to an equilibrium price of $500. In Elastic City, the price elasticity of supply of housing is 5.0. In Rigid City, the supply elasticity is 0.40. a

Leapfrog city has two rings of vacant land suitable for housing, one that is three miles from the center and a second that at the edge of the city, six miles from the center. Both rings were expected to be developed in the next year. Suppose the city imposes a new development tax of $20,000 per new h
