• The difference between actual growth
and the trend rate of growth
• Where would these be on your chart?
• Output lost in a recession is regained in
a boom but….
Hysteresis
• The trend rate of growth can shift
downwards if there is a deep recession
due to permanent losses of human and
physical capital
• Loss of skills – structural change
• Long term unemployed
• Cut backs in investment
• Outdated technology
• ‘potential’ falls
