2 part question

The Greek letter a represents a number that determines how much output responds to unexpected
changes in the price level. In this case, assume that a = $2 billion. That is, when the actual price
level exceeds the expected price level by 1, the quantity of output supplied will exceed the natural
level of output by $2 billion.
Suppose the natural level of output is $60 billion of real GDP and that people expect a price level of
110.
On the following graph, use the purple line (diamond symbol) to plot this economy's long-run
aggregate supply (LRAS) curve. Then use the orange line segments (square symbol) to plot the
economy's short-run aggregate supply (AS) curve at each of the following price levels: 100, 105,
110, 115, and 120.

PRICE LEVEL
In the short run, the quantity of output that firms supply can deviate from the natural level of
output if the actual price level in the economy deviates from the expected price level. Several
theories explain how this might happen.
For example, the sticky-price theory asserts that the output prices of some goods and services
adjust slowly to changes in the price level. Suppose firms announce the prices for their products in
advance, based on an expected price level of 100 for the coming year. Many of the firms sell their
goods through catalogs and face high costs of reprinting if they change prices. The actual price
level turns out to be 110. Faced with high menu costs, the firms that rely on catalog sales choose
not to adjust their prices. Sales from catalogs will
catalogs will respond by
high costs of adjusting prices, the unexpected increase in the price level causes the quantity of
output supplied to
and firms that rely on
v the quantity of output they supply. If enough firms face
the natural level of output in the short run.
