a) A fiscal expansionary policy is used when the economy is in
recession or is slowing down. It increases the government
expenditure which leads to increase in transaction demand for money
causing interest rate to increase at given money supply. When
interest rate increases, it increases the cost of borrowing which
leads to decrease in private investment (this is called crowding
out effect, the decrease in private investment due to increase in
government spending). Also, an increased interest rate attracts
investors which increases the met capital inflow in the country
leading to appreciation of the domestic currency. As currency has
appreciated, so, exports become costly but imports become cheap
increasing the demand for imports but decreasing the demand for
exports this leads to a decrease in net exports (this is called the
net-exports effect). The increased government spending increases
the aggregate demand for goods and services which at given
aggregate supply leads to an increase in price level and output.
This increase in output leads to a decrease in unemployment as now
more labor is required for production.
b) A fiscal contractionary policy is used when the economy is in
a boom phase. It decreases the government expenditure which leads
to decrease in transaction demand for money causing interest rate
to decrease at given money supply. When interest rate decreases ,
it decreases the cost of borrowing which leads to increase in
private investment. Also, a decreased interest rate dicourages
investors which increases the met capital outflow from the country
leading to depreciation of the domestic currency. As currency has
depreciated, so, exports become cheaper but imports become
expensive increasing the demand for exports but decreasing the
demand for imports this leads to an increase in net exports (this
is called the net-exports effect). The decreased government
spending decreases the aggregate demand for goods and services
which at given aggregate supply leads to a decrease in price level
and output. This decrease in output leads to an increase
in unemployment as now less labor is required for
production.
