The following graph shows a decrease in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the left from AD1AD1 to AD2AD2, causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion.
The following table lists several determinants of aggregate demand.
Complete the table by indicating the change in each determinant necessary to decrease aggregate demand.

The following graph shows the short-run and long-run aggregate supply curves (SRAS and LRAS) for an economy.
Suppose there is a technological improvement that allows firms to reduce their costs of production permanently.
Drag one or both of the curves on the graph to illustrate the long-term effects of this change. If you don't believe there will be any long-term effects,
leave the curves where they are.

6. Why the aggregate supply curve slopes upward in the short run
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
, and firms that rely on catalogs
will respond by
the quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected…

- The following graph shows an aggregate demand curve (AD) illustrating the inverse relationship between the price level and the quantity of Real GDP in the United States. During World War II, the United States increased military spending. Show the effect of the following scenario on the aggregate demand curve by dragging the curve or moving the point to the appropriate position. Note: Tool tip: To move the curve, click and drag any part of the curve. The curve will snap into position, so if you try to move it and it snaps back to its original position, just try again and drag it a little farther.
