1. Macroeconomic equilibrium is when the quantity of aggregate demand.
2. Increased inflation: Increased government spending can lead to increased inflation. This is because central banks may raise interest rates in response to increased inflation and output, which can erode some of the expansionary gains.
3. Movement along the Phillips curve an increase in fiscal spending can lead to a movement along the Phillips cure, where unemployment falls and inflation rises.
4. Crowding out effect: An increase in government spending can lead to the crowding out effect, where the governments spending on a social welfare macroeconomic equilibrium is when the quantity of aggregate demand is equal to the quantity of aggregate supply.
Changes in aggregate demand or aggregate supply can lead to changes in inflation, unemployment and price.
