ECON 103 Chapter Notes - Chapter 20.2: Aggregate Supply, Aggregate Demand, Price Level
Document Summary
Why does the aggregate demand curve slope downward: a decrease in the price level raises the real value of money and makes consumers wealthier, which in turn encourages them to spend more. This depreciation stimulates u. s net exports and thereby increases the quantity of goods and services demanded. Conversely, when the us price level rises and causes us interest rates to rise, the real value of the dollar increases, and this appreciation reduces us net exports and the quantity of goods and services demanded. Why the aggregate demand curve might shift: any event that changes how much people want to consume at a given price level shifts the curve. Changes in taxation is an example: firms being optimistic or pessimistic about future business conditions, tax policy, money supply, changes in government purchases, changes in net exports. Why the aggregate supply curve is vertical in the long run: price level does not affect the long run determinants of real gdp.
