1. Does the Aggregate Demand (AD) curve always slope downward? Discuss and use explanations (interest rate effect, wealth effects, open economy effect).
2. The Aggregate Supply (AS) curve slopes upward to reflect the profit motive of businesses. So, why there are two versions of the AS curve( i.e. short run and long- run). Discuss.
3. Does Aggregate Demand and Aggregate Supply always occur at full-employment level?
a) If yes, will there be some unemployment? Explain
b) If no, then the actual real GDP may be different from the potential real GDP. When the actual and potential GDP are not the same, then the economy is either in a recessionary gap or inflationary gap. Explain
