2 - ) Briefly explain the “consumption link” and “real wealth effect”.
Consumption link: P↑ Md↑ r↑ c↓ Y↓ an increase in the price level increases the demand for
money, which leads to an increase in the interest rate which leads to a decrease in

consumption which leads to a decrease in aggregate output. The initial decrease in
consumption contributes to the overall decrease in output. Planned investment does not bear
all the burden of providing the link from a higher interest rate to a lower level of aggregate
output.
Real wealth effect: an increase in price level may lower the real value of stocks and housing.
If stock prices and housing prices rise by the same percentage as the overall price level, the
real value of wealth remain unchanged. If real wealth falls, this leads to a decrease in
consumption, which leads to a decrease in aggregate output. So, change in consumption
brought about by a change in real wealth results from a change in price level.
