The document describes three economic shocks and asks how each would affect equilibrium output and prices in the short-run and long-run according to the Aggregate Demand-Aggregate Supply model. The first shock is a large increase in commodity prices which would likely decrease output and increase prices in the short-run. The second shock is more Canadians vacationing and shopping domestically which would increase aggregate demand and output in the short-run. The third shock discusses new energy technologies which would decrease costs and increase output in the long-run.
