In normal circumstances, ceteris paribus, the supply curve shifts left as competition drives down prices.
The aggregate demand curve shifts to the right
right
In economics, the supply curve in the aggregate supply and demand model shifts drastically to the left due to an inadequacy of resources or because the demand overpowers the supply.
Prices rise, output rises
ceteris paribus this would lead to the equilibrium production decreasing, with the price effect depending on the characteristics of the supply relation.

Prices rise, output rises
Aggregate expenditures will shifts down by the decline in aggregate expenditures.
Movements along the aggregate demand curve are caused by changes in price level - real wealth effect, interest rate effect and open economy effect. If some non-price level determinant causes total spending to increase/decrease then the curve will shift to the right/left - consumption, investment, government expenditure, net exports.
a
If aggregate demand increases at every price level than the demand curve shifts to the right. In the short-run the new equilibrium forms from an increase in willingness to spend, thus higher prices and higher real GDP or quantity of output. If short-run aggregate supply increases at every price level than the supply curve shifts to the right. From the short-run to the long-run the new equilibrium forms from an increase willingness to sell, thus prices reduce to original equilibrium and output increases further. Recap: Prices stay constant while real GDP or total quantity of output increases.
