Q

What is a short-run aggregate supply (SRAS) curve?

A

A short-run aggregate supply (SRAS) curve shows the quantity supplied of all goods & services (Real GDP) at different price levels, ceteris paribus.

17
Q

Define short-run equilibrium.

A

Short-run equilibrium is the condition in the economy when the quantity demanded and Real GDP equals the (short-run) quantity supplied of Real GDP.

Short-run equilibrium is met where the aggregate demand curve intersects the short-run aggregate supply curve.

18
Q

What is Natural Real GDP?

A

Natural Real GDP is the Real GDP that’s produced at the natural unemployment rate and when the economy is in long-run equilibrium.

19
Q

What is a long-run aggregate supply (LRAS) curve?

A

A long-run aggregate supply (LRAS) curve represents the output the economy produces when wages and prices have adjusted to their final equilibrium levels and when workers don’t have any relevant misperceptions.

The LRAS line is a vertical line at the level of the Natural Real GDP.

20
Q

Define long-run equilibrium.

A

Long-run equilibrium is the condition that exists in the economy when wages and prices have adjusted to their (final) equilibrium levels and when workers don’t have any relevant misperceptions.

On a graph, the long-run equilibrium occurs at the intersection of the AD and LRAS curves.
