Why does the demand curve from top left to bottom right
Real Balance effect - As price level rises, the real value of peoples income falls so consumers are less able to buy the items they want or need.
Interest rate effect - If the price levels rises, this causes inflation and an increase in the demand for money and so a possible rise in interest rates with a deflationary effect on the economy.
When is there movement along the demand line
There is a movement along the demand curve when the quantity wanted of a single commodity changes due to a change in price, while all other factors remain constant
When does the demand curve shift
at each possible price due to a change in one or more other factors.
