Economists who view the AS curve as upward-sloping believe that changes on the demand side result in changes in Real GDP in the short run. Economists who view the AS curve as vertical believe that government changes from the demand side to raise Real GDP in the short run

May; cannot do anything

Explanation:

In the short run, the aggregate supply curve will react to price level, which means it is upward sloping rather than vertical. If the price level increases, quantity supplied will increase. If the price level decreases, the quantity supplied will decrease.

Economists who view the AS curve as upward-sloping believe that changes on the demand side CAN result in changes in Real GDP in the short run. Economists who view the AS curve as vertical believe that government changes from the demand side CANNOT DO ANYTHING to raise Real GDP in the short run.

Explanation:

In the short run, the aggregate supply (AS) curve is upward sloping because most input prices are fixed in the short run. So a change in the aggregate demand will cause the AS curve to change in the short run. If the demand increases, the aggregate supply will increase, and vice versa.

On the long run, input prices are not fixed, so the AS curve is vertical and any changes in the aggregate demand will not affect it.

comment it always confuses me

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
