In the aggregate demand and aggregate supply model: 0 the factors that cause the individual demand curve to slope downward are the same as the factors that cause the aggregate demand curve to slope downward. O the factors that cause the individual supply curve to slope upward are the same as the factors that cause the short-run aggregate supply curve to slope upward. O the upward-sloping aggregate demand curve intersects the downward-sloping short-run aggregate supply curve to determine the economy's price level and GDP. 0 the upward-sloping short-run aggregate supply curve intersects the downward-sloping aggregate demand curve to determine the economy's price level and GDP
