The following graph shows a decrease in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar. Specifically, the short-run aggregate supply curve shifts to the left from AS, to A$2, causing the quantity of output supplied at a price level of 100 to fall from $200 billion to $150 billion.
