Price Level LAS SAS, SAS, AD SAS, AD, AD, Real Output Refer to the graph. Suppose the economy is at SAS, and AD₂. What is a possible way the economy can return to potential output? What dynamic price level feedback effect could prevent the return to potential output? How would the dynamic price level feedback effect show up in the graph? O A decrease in asset prices in the economy; a decrease in asset prices would further decrease AD; a shift in AD from AD2 to AD3 O A decrease in material costs in the economy; a decrease in material costs would decrease AD; a shift in AD from AD2 to AD1 A decrease in wages in the economy; a decrease in wages would further decrease AD; a shift in AD from AD2 to AD3 A decrease in wages in the economy; a decrease in wages would further decrease AD; a shift in AD from AD2 to AD1

6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the sticky-wage theory asserts that output prices adjust more quickly to changes in the price level than wages do, in part because of long-term wage contracts. Suppose a firm signs a contract agreeing to pay its workers $15 per hour for the next year, based on an expected price level of 100. If the actual price level turns out to be 90, the firm's output prices will , and the wages the firm pays its workers will remain fixed at the contracted level. The firm will respond to the unexpected decrease in the price level by v the quantity of output it supplies. If many firms face similarly rigid wage contracts, the unexpected decrease in the price level causes the quantity of output…
