Well, aggregate supply is the total output of goods and services that producers in an economy are willing and able to supply at different price levels in a given time period. Aggregate supply can be modeled on a diagram in two ways: the long run and the short run.
- A fall in interest rates. This will encourage businesses to invest therefore allowing them to expand and increase supply. This will shift LRAS to LRAS 1 on the diagram. If interest rates rose the opposite would happen and we could end up at curve LRAS 2 on the diagram.
- Unemployment related benefits could be reduced. This would encourage more to try and get back into work, thus giving more potential labour for firms. This will increase LRAS to LRAS 1. The opposite would happen if unemployment related benefits were increased.
- Education and training will improve the productivity of the workforce.. pushing LRAS out to LRAS 1. If funding for education and training was cut then LRAS may fall to curve LRAS 2.
