Concept Introduction:

Inflation: It is defined as the continuous rise in price of all the goods and services for a span of time in the economy.

Gross Domestic Product (GDP): It is defined as the value of output which is produced domestically that is inside the borders of the country in the given interval of time.

Aggregate Demand Curve (AD): It shows how price and the quantity demanded are related to each other. The curve is negatively slopped which means that when prices rise the quantity demanded falls.

Aggregate Supply Curve (AS): It shows how price and the quantity supplied are related to each other. The curve is positively slopped which means that when prices rise, the quantity supplied also rises. The curve depends on the duration of time.

Short Run Aggregate Supply (SRAS): It is a positively slopped curve in which supply increases when price rises.

Long Run Aggregate Supply (LRAS): It is a vertical curve which is independent of time. When price increases there is no change in quantity supplied.

Short Description 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 800 billion dollars with an increment of 40 billion dollars, and the y-axis is scaled from 30 to 150 units with an increment of 5 units.   Object Details On the graph we have:Four Line Objects:An upward sloping Aggregate Supply, AS line with two endpoints:Point 1 at (160, 70)Point 2 at (720, 140)A downward sloping Aggregate Demand, AD1 line with two endpoints:Point 1 at (80, 110)Point 2 at (640, 40)A vertical Long-run Aggregate Supply, LRAS with two endpoints:Point 1 at (400, 145)Point 2 at (400, 30)A downward sloping Aggregate Demand, AD line with two endpoints:Point 1 at (720, 60)Point 2 at (160, 130)Two Reference Points:Lines AS, AD, and LRAS intersect at (400, 100)Lines AS  and AD1 intersect at (280, 85) a.
