|
A supply shock is an event that suddenly changes the price of a commodity or service. It may be caused by a sudden increase or decrease in the supply of a particular good. This sudden change affects the equilibrium price.
A negative supply shock (sudden supply decrease) will raise prices and shift the aggregate supply curve to the left. A negative supply shock can cause stagflation due to a combination of raising prices and falling output.
A positive supply shock (an increase in supply) will lower the price of said good and shift the aggregate supply curve to the right.
An example of a supply shock is the increase in oil prices during the 1973 energy crisis.
