Question

Aggreate demand and aggregate supply approach class 12 macro economics

Answer 1

Firms make decisions about what quantity to supply based on the profits they expect to earn. Profits, in turn, are also determined by the price of the outputs the firm sells and by the price of the inputs—like labor or raw materials—the firm needs to buy. Aggregate supply, or AS, refers to the total quantity of output—in other words, real GDP—firms will produce and sell. The aggregate supply curve shows the total quantity of output—real GDP—that firms will produce and sell at each price level.
The graph below shows an aggregate supply curve. Let's begin by walking through the elements of the diagram one at a time: the horizontal and vertical axes, the aggregate supply curve itself, and the meaning of the potential GDP vertical line.
