Q

Keynesian LRAS Curve

A

Below Y1 is elastic as output can be increased, because there is high unemployment, workers have little power in demanding wage increases, and because spare resources can be bought without increasing price, inflation will not rise as output rises

In the Long Run, Keynes disagrees with eh Classical LRAS view that wages will fall and go back to equilibrium in a recession, as wages are ‘sticky’, meaning workers will be very reluctant to take a pay cut even in times of recession

Q

Neo-classical view of LRAS

A

In the Long-Run, an economy will always be at full employment level of output, hence why it is vertical

The economy will respond to shocks and return to equilibrium. e.g.in recession, factor prices (WAGES, rents) will fall, as they fall, demand will rise again .
