Aggregate Supply & Demand
- The short-run macroeconomic equilibrium occurs where the SRAS = AD
- The long-run macroeconomic equilibrium occurs where the LRAS = AD
- If the short-run equilibrium is to the left of the long-run equilibrium, the economy is experiencing a recession
- If the short-run equilibrium is to the right of the long-run equilibrium, the economy is experiencing inflation
- In the long-run, the economy will “self-correct” with the SRAS moving back to the LRAS
- Expansionary fiscal and monetary policy make sense when the economy is experiencing a recession
- Contractionary fiscal and monetary policy usually take place in reaction to inflationary times

Why does increasing the prices of oil shift the supply to the left again? I thought that higher prices ==> larger incentive for aggregate suppliers to produce more ==> more supply.

I thought example 4 should be A because the tax multiplier should always have a greater magnitude at every MPC value, so if the government spending is the same as the amount taxes are increased, the taxes would have a greater impact.
