3. The supply and demand for land for residential development is shown in the diagram above. The land supplied
for such development comes from privately held openspace land or privately held farmland.

a) Redraw the graph above and show how an increase in
income will affect the equilibrium price and quantity of
land converted into residential development, assuming
that the land for residential development is a normal
good.

b) Redraw the graph above and show how a decrease in government
per-unit subsidies to farmers will affect the equilibrium price and
quantity of land converted into residential development.
Note: If you assume the Subsidy was for “selling” land, then any decrease
Will shift Supply to the left.
Generally speaking: less subsidy shifts supply left
more subsidy shifts supply right

c) Assume that the conversion of open-space land and
farmland imposes costs on the general population,
which can no longer enjoy the scenic vistas.
i) Indicate whether the marginal social cost of converting land is greater
than, less than, or equal to the marginal private cost of converting land.
MCT > MCP

ii) Explain whether the private market quantity of land converted into
residential development is socially optimal.
No, because MCT > MBP
Private Costs MCP fail to include all social costs

Too much land is converted into residential development.
