## What is AD and AS curve?

The AD–AS or aggregate demand–aggregate supply model is a macroeconomic model that explains price level and output through the relationship of aggregate demand and aggregate supply.

What does the AS curve represent?

The aggregate supply curve Aggregate supply, or AS, refers to the total quantity of output—in other words, real GDP—firms will produce and sell. The aggregate supply curve shows the total quantity of output—real GDP—that firms will produce and sell at each price level.

What do the aggregate supply and aggregate demand curves describe?

Aggregate supply is the total quantity of output firms will produce and sell—in other words, the real GDP. Aggregate demand is the amount of total spending on domestic goods and services in an economy.

### Why are there two aggregate supply curves?

Like changes in aggregate demand, changes in aggregate supply are not caused by changes in the price level. Instead, they are primarily caused by changes in two other factors. The first of these is a change in input prices. A second factor that causes the aggregate supply curve to shift is economic growth.

Is LM and as AD?

The IS-LM model relates the real interest rate to output. The AD-AS model relates the price level to output.

What happens when ad as?

The aggregate demand curve shifts to the right as the components of aggregate demand—consumption spending, investment spending, government spending, and spending on exports minus imports—rise. If the AD curve shifts to the right, then the equilibrium quantity of output and the price level will rise.

#### Is curve a diagram?

The goods market equilibrium schedule is the IS curve (schedule). It shows combinations of interest rates and levels of output such that planned (desired) spending (expenditure) equals income. The goods- market equilibrium schedule is a simple extension of income determination with a 45° line diagram.

What is the shape of AS curve?

In the short-run, the aggregate supply curve is upward sloping. There are two main reasons why the quantity supplied increases as the price rises: The AS curve is drawn using a nominal variable, such as the nominal wage rate. In the short-run, the nominal wage rate is fixed.

What is the relationship between aggregate demand and price level?

In the most general sense (and assuming ceteris paribus conditions), an increase in aggregate demand corresponds with an increase in the price level; conversely, a decrease in aggregate demand corresponds with a lower price level.

## How do you shift the aggregate supply curve?

A shift in aggregate supply can be attributed to many variables, including changes in the size and quality of labor, technological innovations, an increase in wages, an increase in production costs, changes in producer taxes, and subsidies and changes in inflation.

What increases aggregate supply?

Why is long run as curve vertical?

Why is the LRAS vertical? The LRAS is vertical because, in the long-run, the potential output an economy can produce isn’t related to the price level. The LRAS curve is also vertical at the full-employment level of output because this is the amount that would be produced once prices are fully able to adjust.

### How is the as curve related to the AD curve?

Figure 1 combines the AS curve and the AD curve from Figures 1 & 2 on the previous page and places them both on a single diagram. The intersection of the aggregate supply and aggregate demand curves shows the equilibrium level of real GDP and the equilibrium price level in the economy.

Which is locus of equilibrium does the AD curve represent?

The AD curve represents the locus of equilibrium in the IS–LM model, also invented and developed by Keynes. The two models produce the same results with a constant price level.

What happens in the flat part of the as curve?

In the relatively flat part of the AS curve, where the equilibrium occurs, changes in the price level will not be a major concern, since such changes are likely to be small. Step 7. Determine what the steep portion of the AS curve indicates. Where the AS curve is steep, the economy is at or close to potential GDP. Step 8.

#### What happens to the AD curve during a Keynesian expansion?

Keynesian Case: If there is a fiscal expansion i.e. there is an increase in the government spending or a cut in the taxes, it will shift the AD curve rightwards. The shift would then imply an increase in the equilibrium output and employment. In the Classical case, the AS curve is vertical at the full employment level of output.

Figure 1 combines the AS curve and the AD curve from Figures 1 & 2 on the previous page and places them both on a single diagram. The intersection of the aggregate supply and aggregate demand curves shows the equilibrium level of real GDP and the equilibrium price level in the economy.

What are the four properties of indifference curves?

Four Properties of Indifference Curves 1. Indifference Curves are Downward Sloping 2. Higher Indifference Curves Are Preferred to Lower Ones 3. Indifference Curves Cannot Intersect 4. Indifference Curves are convex (i.e. bowed inward) In a Nutshell

Which is the correct description of a downward curve?

A curve that points towards the downward direction is called a downward curve. The downward curves are called concave downward or convex upward curves. A curved line is a line that is not straight and is bent.

## What do you call a concave upward curve?

The upward curves are called concave upward or convex downward curves. A curve that points towards the downward direction is called a downward curve. The downward curves are called concave downward or convex upward curves.
