Expert Solution

1. When aggregate price level in the economy falls, then the interest rate in the economy falls, which leads to increase in investent in the economy . This phenomenon is called the interest rate effect. Because lower interest rate means lower mortgage payments ,which tends to increase investment ,therefore investment rises when the price falls. Hence, option(B) is correct.

2. The Quantity theory of money is used to explain why the AD curve is downward sloping.Because high output means people engage in more transactions and need higher real money balances (M/P). Therefore, for a fixed level of M ,higher M/P implies a lower price level. In other words. a lower P means M/P will be higher wihich allows greater volume of transactions , so more output is demanded. Hence, option(C) is correct.

3. The misperceptions theory can be used to explain why the SRAS curve is upward sloping. Hence, option(B) is correct.

4. The LRAS curve will shift right if there is a discovery of a new huge coal mine. Hence, option(B) is correct.

5. Okun's law states that an extra unit of unemployment will lead to a 2% decrease in output . Hence, option(A) is correct.

6. The Phillips curve is downward sloping in the short run that shows the inverse relationship between inflation and unemployment. Hence, option(D) is correct.

According to the real balances effect, as the price level in the U.S. falls, a. Aggregate quantity demanded increases because lower price levels lead to lower interest rates, which stimulates spending. b. The entire aggregate demand curve will shift to the right. c. Aggregate quantity demanded increases because lower price levels cause the purchasing power of the dollar to increase. d. Aggregate quantity demanded increases because U.S. consumers tend to buy more domestically-produced goods/services and fewer imports. e. Answers b)....

Explain why the aggregate demand curve is downward sloping. (As the price level falls, the quantity of real output demanded increases.). List five factors that might cause the AD curve to shift outward (i.e. more is demanded at the same price).

1. The aggregate supply curve shows the relationship between the aggregate price level and the aggregate: output supplied. money supply. unemployment rate. employment. 2. The short-run aggregate supply curve shows: the price level at which real output will be consumed. the price level at which real output will be in equilibrium. the positive relationship between the aggregate price level and aggregate output supplied. the negative relationship between the aggregate price level and aggregate output supplied. 3. A change in _____...
