Suppose the marginal value of a square foot of factory space is constant at $1.00. The marginal benefit of a square foot of housing space is $1.00 for 1,000 square feet and $0.80 for 1,200 square feet. Suppose the government provides a 20 percent mortgage subsidy, cutting the net price of housing to
