Answer:
Natural GDP is the optimum quantity of goods and services that a country is expected to be producing per year. It is based on the various resources and constraints available in the economy.
Real GDP is the inflation adjusted value of goods and services actually produced in the country in a year.
1. Q < Qn ⇒ Recessionary Gap ⇒ Surplus in labor market ⇒ Wages will fall ⇒ SRAS will shift right ⇒ Below PPF
At this point where Natural GDP is above Real GDP, the nation is underproducing which means it is in a recessionary gap. Many will be unemployed so there will be a surplus in the labor market which makes labor cheap so wages will fall. The SRAS will shift right as input costs will be lower (wages) but the economy is inefficient so it is below its PPF.
2. Q > Qn ⇒ Inflationary Gap ⇒ Shortage in Labor market ⇒ Wages rise ⇒ SRAS shifts left ⇒ Above PPF
Real GDP is higher than the Natural GDP. The economy will be in an inflationary gap as a result and there will be a shortage in the labor market s companies look for more people to produce more which will lead to a rise in wages. With the ride in wages comes a rise in production costs so SRAS will shift left. The country will be above its PPF which is unattainable.
3. Q = Qn ⇒ Long Run Equilibrium ⇒ Labor Market Equilibrium ⇒ Unchanged wages ⇒ Unchanged SRAS ⇒ Producing at PPF boundary
This is the ideal situation where Real GDP equals Natural. Here the economy will be in a long run equilibrium where the labor market will also be in equilibrium which means that wages will not change, SRAS will remain where it is and the economy will be at the Production Possibilities Frontier (PPF) boundary.
