How does rate of interest affect consumption, investment, government, or net export expenditures, and explain how a change in this factor affects:

• Consumption, investment, government, or net export expenditures (Lower consumption?)
• Aggregate Expenditures (high rates decrease expenditures = less consumption?)
• Aggregate Demand(lower interest rate = more consumption and investments?)
• Real GDP(Increase in rates = decrease in GDP?)
• Price Level (Inflation. Increase is price level = increase in rate of interest?)

I have a pretty good idea - I hope I am on the right track and appreciate your help.
