Assume that two shocks happen simultaneously: a positive expenditure shock (let's say a popular trend is to go for a bigger house) and a positive supply shock (let's say prices on imported inputs decreased dramatically due to a substantial reduction in tariffs). Use AE/PC Model (carefully labeled!!) without time lags (use the AE and PC graphs similarly to the textbook, place PC graph below AE graph). For your analysis, choose as a starting point (marked A) an economy operating at potential GDP (Y=Y*) and at its inflation target ( = !). Also, show point B where the economy is situated after the shocks but prior to any central bank policy response. There should be A and B on BOTH the upper (AE graph) and lower (PC graph) graphs. If points A and B are the same point, then just mark that point with both A and B. Mark initial curves with the

superscript 1, like AE and PC , and every subsequent shift with a higher number,

like the second shift would be AE and PC , and the third shift (if necessarily)

would be AE3and PC3and so on. Describe that situation.
