3. What is the difference between the long-run aggregate supply (LRAS) and the short-run aggregate supply (SRAS) curves? Give examples of factors that decrease SRAS. Which way does the SRAS curve shift?
Only typed Answer
Determine whether each of the following would cause a shift of the aggregate demand curve, a shift of the aggregate supply curve, a shift in neither curve, or shift in both curves. If a shift is caused, indicate which curve shifts, and in which direction it shifts. What happens to aggregate output and the price level in each case? 4. The wages rate decreases.
