Concept Introduction:

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 rises, 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. The reason for upward slopping is that the wages are sticky in the short run due to formal or informal contracts. At higher aggregate prices there is a higher profit leading to a high level of output.

Long Run Aggregate Supply ( LRAS ): It is a vertical curve which means it is an independent of price. When price increases, there is no change in the quantity supplied. In the long run, nominal wages are not fixed rather it can be negotiated.

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