- Fiscal Policy Graph Details Shown is a Fiscal Policy diagram with the variable Real GDP (billions of dollars) on the x-axis and the variable Price Level on the y-axis. The x-axis is scaled from 0 to 1000 billion dollars with an increment of 50 billion dollars, and the y-axis is scaled from 0 to 180 units with an increment of 10 units. Object Details On the graph we have:Four Line Objects:An upward sloping Aggregate Supply, AS line with two endpoints:Point 1 at (200, 40)Point 2 at (800, 160)A downward sloping Aggregate Demand, AD line with two endpoints:Point 1 at (200, 160)Point 2 at (800, 40)A downward sloping Aggregate Demand, AD1 line with two endpoints:Point 1 at (350, 170)Point 2 at (900, 60)A vertical Long-run Aggregate Supply, LRAS line with two endpoints:Point 1 at (500, 170)Point 2 at (500, 0)Two Reference Points:Lines AS and AD1 intersect at (600, 120)Lines AS, AD, and LRAS intersect at (500, 100) a.
