Explanation:

The Aggregate Demand (AD) curve is used to measure the impact that price level has on the expenditure in the economy.

The AD comprises of Investment, Consumption Spending, Government spending and Net Income.

When prices are high, households will spend less as they cannot afford to spend a lot which will reduce consumption spending.

Another result of a high price level is that people will have less money to save and so there will be a lower supply of loanable funds.

Both of these components of the AD reduce when prices increase and vice versa. This is why the AD is downward slopping.
