City officials are devising two alternative policies to reduce the risk of eviction for families living downtown, where rent has increased precipitously. One proposed policy is to divert housing demand away by building low‑income apartments in the surrounding area. The other proposed policy is to subsidize the development of low‑income apartments within the downtown area. For simplicity, assume that these are two bedroom apartments that have all the same attributes and that the slope of the supply and demand curves do not change. The line P0 in the diagram shows the current rent. The objective of any policy is to lower the rent to P1 while minimizing the impact on the quantity of apartments available. Show the optimal policy impact on the graph by shifting either the supply or demand curve.
