Document Summary

Macroeconomics policy lecture 6 (chapter 23) An increase in p thus reduces private-sector wealth: reduction in desired consumption, downward shift in ae curve. There is also an effect on net exports: A fall in p raises the real value of money holdings. Much of private sector"s total wealth is held in the form of assets with a fixed nominal value. An increase in p reduces the real value of money holdings. An increase in p reduces desired aggregate expenditure: ae shifts down, equilibrium y falls. Aggregate demand: relates equilibrium real gdp to the price level. For any given p, the ad curve shows the level of real gdp for which desired aggregate expenditure equals actual gdp. Changes in the price level causes movements along the ad curve. A rise in the price level = ae curve shifts down, but we move along the ad curve. The aggregate demand (ad) is negatively sloped for two reasons:
