To determine

Illustrate the aggregate demand curve and the factors that shift it

Explanation of Solution

In macroeconomics, the emphasis is on the demand and supply of all products and services produced by an economy. Appropriately, the demand for every single individual goods and service is likewise consolidated and referred to aggregate demand.

The total/aggregate demand curve depicts the aggregate amount of all products (and services) demanded by the economy at various price levels. A case of a total demand curve is given in Figure 1 as follows:

The vertical axis indicates the price levels of all final goods and services. The total price level is estimated by either the GDP deflator or the CPI. The horizontal axis speaks about the genuine amount of all products and services acquired as estimated by the level of real GDP. Notice that the total demand curve, AD, similar to the demand curves for singular merchandise is downward sloping, inferring that there is an inverse connection between the price level and the quantity demanded of real GDP.

Shifts of Aggregate Demand Curve

Changes in aggregate demand are indicated by shifts in the aggregate demand curve. A representation of the two ways by which the total demand curve can move is given in Figure 2 as follows:

A shift to the right of the aggregate demand curve from AD 1 to AD 2, implies that at a similar price level the quantity demanded of real GDP has expanded. A shift to the left of the aggregate demand curve, from AD 1 to AD 3, implies that at a similar price level the quantity demanded of real GDP has diminished.

Changes in aggregate demand are not caused by changes in the price level. Rather, they are caused by changes in the demand for any of the parts of real GDP. Changes in the demand for consumption of products and services, changes in investment spending, changes in the government demand for merchandise and services, or changes in the demand for net exports.

Think about a few cases. Assume shop Keepers were to diminish their spending on all merchandise and services, maybe because of a recession. At that point, the total demand curve would move to the left.

Assume loan fees as interest rates were to fall with the goal that financial specialist expand their investment spending; the total demand curve would move to the right.

If government somehow managed to slice spending to lessen a budget deficit, the total demand curve would move to the left.

In the event that the livelihoods of foreigners were to rise, empowering them to request more domestic-made merchandise, net exports would increment, and total demand would move to the right.

These are only a couple of the numerous conceivable ways the total aggregate demand may move. None of these clarifications, in any case, has anything to do with changes in the price level.

The total/aggregate demand curve depicts the aggregate amount of all products (and services) demanded by the economy at various price levels. Changes in aggregate demand are not caused by changes in the price level. Rather, they are caused by changes in the demand for any of the parts of real GDP. Changes in the demand for consumption of products and services, Changes in investment spending, Changes in the government demand for merchandise and services, or changes in the demand for net exports.
