What is maximum sustainable capacity?

• The total output an economic system will produce over a set period of time if all resources are fully employed

• The total output an economic system will produce in the short-run if all resources are fully employed

Where is the LRAS vertical?

• At the full-employment level of output

• At the zero inflation level of output

• At the 2% inflation level of output

• At 2% real GDP growth

Why is the LRAS curve vertical?

• In the long run wages and prices fully adjust

• In the long run prices are infinite

• In the long run, we're all dead

• In the long run wages don't equal productivity.

Match the following

• Economy experiencing inflation, economy above full employment, UE < NRU

• 
• Economy at full employment in long-run equilibrium, experiencing NRU

• 
• Economy in recession, below full employment, UE is above the natural rate
