All of the following would cause a shift in the aggregate supply curve except:. a. a change in the price level.
b. an increase in the real wages of workers.
c. a decrease in productivity.
d. the emergence of a new production technology.
e. a tax on all manufactured goods.

a change in the price level.

Explanation:

A shift in the aggregate supply curve is caused by non-price changes such as real wages of the workers, tax, technological innovation, productivity level etc.

The change in price will only result in the movement along the supply curve, which is also referred to as the change in quantity supplied. A change in price will not cause a shift on the aggregate supply curve.
