40.
The model of aggregate demand and aggregate supply
a.
is different from the model of supply and demand for a particular market, in that we cannot
focus on the
substitution of resources between markets to explain aggregate relationships.
b.
is different from the model of supply and demand for a particular market, in that we have to
separate real and
nominal variables in the aggregate model.
c.
is a straightforward extension of the model of supply and demand for a particular market, in
which substitution
of resources between markets is highlighted.
d.
is a straightforward extension of the model of supply and demand for a particular market, in
which the
interaction between real and nominal variables is highlighted.
